-FreeType is a freely available software library to render fonts.
|
|
7
|
|
-
|
|
8
|
|
-It is written in C, designed to be small, efficient, highly
|
|
9
|
|
-customizable, and portable while capable of producing high-quality
|
|
10
|
|
-output (glyph images) of most vector and bitmap font formats.
|
|
11
|
|
-
|
|
12
|
|
-Please read the `docs/CHANGES` file, it contains IMPORTANT
|
|
13
|
|
-INFORMATION.
|
|
14
|
|
-
|
|
15
|
|
-Read the files `docs/INSTALL*` for installation instructions; see the
|
|
16
|
|
-file `docs/LICENSE.TXT` for the available licenses.
|

17
|
|
-
|
|
18
|
|
-For using FreeType's git repository instead of a distribution bundle,
|
|
19
|
|
-please read file `README.git`. Note that you have to actually clone
|
|
20
|
|
-the repository; using a snapshot will not work (in other words, don't
|
|
21
|
|
-use gitlab's 'Download' button).
|
|
22
|
|
-
|
|
23
|
|
-The FreeType 2 API reference is located in directory `docs/reference`;
|
|
24
|
|
-use the file `index.html` as the top entry point. [Please note that
|
|
25
|
|
-currently the search function for locally installed documentation
|
|
26
|
|
-doesn't work due to cross-site scripting issues.]

31
|
|
---------------------------------
|
|
32
|
|
-
|
|
33
|
|
-The git repository doesn't contain pre-built configuration scripts for
|
|
34
|
|
-UNIXish platforms. To generate them say
|
|
35
|
|
-
|
|
36
|
|
- sh autogen.sh
|
|
37
|
|
-
|
|
38
|
|
-which in turn depends on the following packages:
|
|
39
|
|
-
|
|
40
|
|
- automake (1.10.1)
|
|
41
|
|
- libtool (2.2.4)
|
|
42
|
|
- autoconf (2.62)
|
|
43
|
|
-
|
|
44
|
|
-The versions given in parentheses are known to work. Newer versions
|
|
45
|
|
-should work too, of course. Note that `autogen.sh` also sets up
|
|
46
|
|
-proper file permissions for the `configure` and auxiliary scripts.
|
|
47
|
|
-
|
|
48
|
|
-The `autogen.sh` script checks whether the versions of the above three
|
|
49
|
|
-tools match the numbers above. Otherwise it will complain and suggest
|
|
50
|
|
-either upgrading or using environment variables to point to more
|
|
51
|
|
-recent versions of the required tools.
|
|
52
|
|
-
|
|
53
|
|
-Note that `aclocal` is provided by the 'automake' package on Linux,
|
|
54
|
|
-and that `libtoolize` is called `glibtoolize` on Darwin (OS X).
|
|
55
|
|
-
|
|
56
|
|
-
|
|
57
|
|
-alternative build methods
|
|
58
|
|
--------------------------
|
|
59
|
|
-
|
|
60
|
|
-For static builds that don't use platform-specific optimizations, no
|
|
61
|
|
-configure script is necessary at all; saying
|
|
62
|
|
-
|
|
63
|
|
- make setup ansi
|
|
64
|
|
- make
|
|
65
|
|
-
|
|
66
|
|
-should work on all platforms that have GNU `make` (or `makepp`).
|
|
67
|
|
-
|
|
68
|
|
-A build with `cmake` or `meson` can be done directly from the git
|
|
69
|
|
-repository. However, if you want to use the `FT_DEBUG_LOGGING` macro
|
|
70
|
|
-(see file `docs/DEBUG` for more information) it is currently mandatory
|
|
71
|
|
-to execute `autogen.sh` in advance; this script clones the 'dlg' git
|
|
72
|
|
-submodule and copies some files into FreeType's source tree.

-This document contains instructions on how to cross-build the FreeType
|
|
2
|
|
-library on Unix systems, for example, building binaries for Linux/MIPS
|
|
3
|
|
-on FreeBSD/i386. Before reading this document, please consult the
|
|
4
|
|
-file `INSTALL.UNIX' for required tools and the basic self-building
|
|
5
|
|
-procedure.
|
|

|
|
-
|
|
7
|
|
-
|
|

|
|
- 1. Required Tools
|
|
9
|
|
- -----------------
|
|
10
|
|
-
|
|
11
|
|
- For self-building the FreeType library on a Unix system, GNU Make
|
|
12
|
|
- 3.81 or newer is required. `INSTALL.UNIX' contains hints how to
|
|
13
|
|
- check the installed `make'.
|
|
14
|
|
-
|
|
15
|
|
- The GNU C compiler to cross-build the target system is required.
|
|
16
|
|
- Currently, using a non-GNU cross compiler is untested. The cross
|
|
17
|
|
- compiler is expected to be installed with a system prefix. For
|
|
18
|
|
- example, if your building system is FreeBSD/i386 and the target
|
|
19
|
|
- system is Linux/MIPS, the cross compiler should be installed with
|
|
20
|
|
- the name `mips-ip22-linuxelf-gcc'.
|
|
21
|
|
-
|
|
22
|
|
- A C compiler for a self-build is required also, to build a tool
|
|
23
|
|
- (`apinames') that is executed during the build procedure. Non-GNU
|
|
24
|
|
- self compilers are acceptable, but such a setup is untested.
|
|
25
|
|
-
|
|
26
|
|
-
|
|
27
|
|
- 2. Configuration
|
|
28
|
|
- ----------------
|
|
29
|
|
-
|
|
30
|
|
- 2.1. Building and target system
|
|
31
|
|
-
|
|
32
|
|
- To configure a cross-build, the options `--host=<system>' and
|
|
33
|
|
- `--build=<system>' must be passed to the `configure' script.
|
|
34
|
|
- For example, if your build system is FreeBSD/i386 and the target
|
|
35
|
|
- system is Linux/MIPS, say
|
|
36
|
|
-
|
|
37
|
|
- ./configure \
|
|
38
|
|
- --build=i386-unknown-freebsd \
|
|
39
|
|
- --host=mips-ip22-linuxelf \
|
|
40
|
|
- [other options]
|
|
41
|
|
-
|
|
42
|
|
- It should be noted that `--host=<system>' specifies the system
|
|
43
|
|
- where the built binaries will be executed, not the system where
|
|
44
|
|
- the build actually happens. Older versions of GNU autoconf use
|
|
45
|
|
- the option pair `--host=' and `--target='. This is broken and
|
|
46
|
|
- doesn't work. Similarly, an explicit CC specification like
|
|
47
|
|
-
|
|
48
|
|
- env CC=mips-ip22-linux-gcc ./configure # BAD
|
|
49
|
|
-
|
|
50
|
|
- or
|
|
51
|
|
-
|
|
52
|
|
- env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD
|
|
53
|
|
-
|
|
54
|
|
- doesn't work either; such a configuration confuses the
|
|
55
|
|
- `configure' script while trying to find the cross and native C
|
|
56
|
|
- compilers.
|
|
57
|
|
-
|
|
58
|
|
-
|
|
59
|
|
- 2.2. The prefix to install FreeType2
|
|
60
|
|
-
|
|
61
|
|
- Setting `--prefix=<prefix>' properly is important. The prefix
|
|
62
|
|
- to install FreeType2 is written into the `freetype-config'
|
|
63
|
|
- script and `freetype2.pc' configuration file.
|
|
64
|
|
-
|
|
65
|
|
- If the built FreeType 2 library is used as a part of the
|
|
66
|
|
- cross-building system, the prefix is expected to be different
|
|
67
|
|
- from the self-building system. For example, a configuration
|
|
68
|
|
- with `--prefix=/usr/local' installs binaries into the
|
|
69
|
|
- system-wide `/usr/local' directory, which then can't be executed
|
|
70
|
|
- due to the incorrect architecture. This causes confusion in
|
|
71
|
|
- configuration of all applications that use FreeType2. Instead,
|
|
72
|
|
- use a prefix to install the cross-build into a separate system
|
|
73
|
|
- tree, for example, `--prefix=/usr/local/mips-ip22-linux/'.
|
|
74
|
|
-
|
|
75
|
|
- On the other hand, if the built FreeType 2 library is used as a
|
|
76
|
|
- part of the target system, the prefix to install should reflect
|
|
77
|
|
- the file system structure of the target system.
|
|
78
|
|
-
|
|
79
|
|
-
|
|
80
|
|
- 2.3. Library dependencies
|
|
81
|
|
-
|
|
82
|
|
- FreeType normally depends on external libraries like `libpng' or
|
|
83
|
|
- `libharfbuzz'. The easiest case is to deactivate all such
|
|
84
|
|
- dependencies using the `--without-XXX' configuration options.
|
|
85
|
|
- However, if you want to use those libraries, you should ensure
|
|
86
|
|
- that they are available both on the target system and as
|
|
87
|
|
- (cross-compiled) libraries on the build system.
|
|
88
|
|
-
|
|
89
|
|
- FreeType uses `pkg-config' to find most of the libraries; the
|
|
90
|
|
- other libraries it links to are expected in the standard system
|
|
91
|
|
- directories. Since the default pkg-config's meta-information
|
|
92
|
|
- files (like `harfbuzz.pc') of the build platform don't work, use
|
|
93
|
|
- one of the two possible solutions below.
|
|
94
|
|
-
|
|
95
|
|
- o Use pkg-config's meta-information files that are adjusted to
|
|
96
|
|
- cross-compile and cross-link with the target platform's
|
|
97
|
|
- libraries. Make sure those files are found before the build
|
|
98
|
|
- system's default files. Example:
|
|
99
|
|
-
|
|
100
|
|
- ./configure \
|
|
101
|
|
- --build=i386-unknown-freebsd \
|
|
102
|
|
- --host=mips-ip22-linuxelf \
|
|
103
|
|
- PKG_CONFIG_LIBDIR="/usr/local/mips-ip22-linux/lib/pkgconfig" \
|
|
104
|
|
- [other options]
|
|
105
|
|
-
|
|
106
|
|
- See the manpage of `pkg-config' for more details.
|
|
107
|
|
-
|
|
108
|
|
- o Set variables like LIBPNG_LIBS as additional options to the
|
|
109
|
|
- `configure' script, overriding the values `pkg-config' would
|
|
110
|
|
- provide. `configure --help' shows the available environment
|
|
111
|
|
- variables. Example:
|
|
112
|
|
-
|
|
113
|
|
- ./configure \
|
|
114
|
|
- --build=i386-unknown-freebsd \
|
|
115
|
|
- --host=mips-ip22-linuxelf \
|
|
116
|
|
- LIBPNG_CFLAGS="-I/usr/local/mips-ip22-linux/include" \
|
|
117
|
|
- LIBPNG_LIBS="-L/usr/local/mips-ip22-linux/lib -lpng12" \
|
|
118
|
|
- [other options]
|
|
119
|
|
-
|
|
120
|
|
-
|
|
121
|
|
- 3. Building command
|
|
122
|
|
- -------------------
|
|
123
|
|
-
|
|
124
|
|
- If the configuration finishes successfully, invoking GNU make
|
|
125
|
|
- builds FreeType2. Just say
|
|
126
|
|
-
|
|
127
|
|
- make
|
|
128
|
|
-
|
|
129
|
|
- or
|
|
130
|
|
-
|
|
131
|
|
- gmake
|
|
132
|
|
-
|
|
133
|
|
- depending on the name the GNU make binary actually has.
|
|
134
|
|
-
|
|
135
|
|
-
|
|
136
|
|
- 4. Installation
|
|
137
|
|
- ---------------
|
|
138
|
|
-
|
|
139
|
|
- Saying
|
|
140
|
|
-
|
|
141
|
|
- make install
|
|
142
|
|
-
|
|
143
|
|
- as usual to install FreeType2 into the directory tree specified by
|
|
144
|
|
- the argument of the `--prefix' option.
|
|
145
|
|
-
|
|
146
|
|
- As noted in section 2.2, FreeType2 is sometimes configured to be
|
|
147
|
|
- installed into the system directory of the target system, and
|
|
148
|
|
- should not be installed in the cross-building system. In such
|
|
149
|
|
- cases, the make variable `DESTDIR' is useful to change the root
|
|
150
|
|
- directory in the installation. For example, after
|
|
151
|
|
-
|
|
152
|
|
- make DESTDIR=/mnt/target_system_root/ install
|
|
153
|
|
-
|
|
154
|
|
- the built FreeType2 library files are installed into the directory
|
|
155
|
|
- `/mnt/target_system_root/<prefix_in_configure>/lib'.

|
|
3
|
|
-running Cygwin or MinGW/MSYS in Windows, you should follow the
|
|
4
|
|
-instructions in the file `INSTALL.UNIX' instead.
|
|
5
|
|
-
|
|
6
|
|
-
|
|
7
|
|
- FreeType 2 includes a powerful and flexible build system that allows
|
|
8
|
|
- you to easily compile it on a great variety of platforms from the
|
|
9
|
|
- command line. To do so, just follow these simple instructions.
|
|
10
|
|
-
|
|
11
|
|
- 1. Install GNU Make
|
|
12
|
|
- -------------------
|
|
13
|
|
-
|
|
14
|
|
- The FreeType 2 build system relies on many features special to GNU
|
|
15
|
|
- Make.
|
|
16
|
|
-
|
|
17
|
|
- NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE', SO REALLY
|
|
18
|
|
- INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
|
|
19
|
|
-
|
|
20
|
|
- Note that make++, a make tool written in Perl, supports enough
|
|
21
|
|
- features of GNU make to compile FreeType. See
|
|
22
|
|
-
|
|
23
|
|
- https://makepp.sourceforge.net
|
|
24
|
|
-
|
|
25
|
|
- for more information; you need version 2.0 or newer, and you must
|
|
26
|
|
- pass option `--norc-substitution'.
|
|
27
|
|
-
|
|
28
|
|
- Make sure that you are invoking GNU Make from the command line, by
|
|
29
|
|
- typing something like:
|
|
30
|
|
-
|
|
31
|
|
- make -v
|
|
32
|
|
-
|
|
33
|
|
- to display its version number.
|
|
34
|
|
-
|
|
35
|
|
- VERSION 3.81 OR NEWER IS NEEDED!
|
|
36
|
|
-
|
|
37
|
|
-
|
|
38
|
|
- 2. Invoke `make'
|
|
39
|
|
- ----------------
|
|
40
|
|
-
|
|
41
|
|
- Go to the root directory of FreeType 2, then simply invoke GNU
|
|
42
|
|
- Make from the command line. This will launch the FreeType 2 host
|
|
43
|
|
- platform detection routines. A summary will be displayed, for
|
|
44
|
|
- example, on Win32.

|
- ==============================================================
|
|
48
|
|
- FreeType build system -- automatic system detection
|
|
49
|
|
-
|
|
50
|
|
- The following settings are used:
|
|
51
|
|
-
|
|
52
|
|
- platform windows
|
|
53
|
|
- compiler gcc
|
|
54
|
|
- configuration directory .\builds\windows
|
|
55
|
|
- configuration rules .\builds\windows\w32-gcc.mk
|
|
56
|
|
-
|
|
57
|
|
- If this does not correspond to your system or settings please
|
|
58
|
|
- remove the file 'config.mk' from this directory then read the
|
|
59
|
|
- INSTALL file for help.
|
|
60
|
|
-
|
|
61
|
|
- Otherwise, simply type 'make' again to build the library
|
|
62
|
|
- or 'make refdoc' to build the API reference (the latter needs
|
|
63
|
|
- Python >= 3.5).
|
|
64
|
|
- =============================================================
|
|
65
|
|
-
|
|
66
|
|
-
|
|
67
|
|
- If the detected settings correspond to your platform and compiler,
|
|
68
|
|
- skip to step 5. Note that if your platform is completely alien to
|
|
69
|
|
- the build system, the detected platform will be `ansi'.
|
|
70
|
|
-
|
|
71
|
|
-
|
|
72
|
|
- 3. Configure the build system for a different compiler
|
|
73
|
|
- ------------------------------------------------------
|
|
74
|
|
-
|
|
75
|
|
- If the build system correctly detected your platform, but you want
|
|
76
|
|
- to use a different compiler than the one specified in the summary
|
|
77
|
|
- (for most platforms, gcc is the default compiler), invoke GNU Make
|
|
78
|
|
- with
|
|
79
|
|
-
|
|
80
|
|
- make setup <compiler>
|
|
81
|
|
-
|
|
82
|
|
- Examples:
|
|
83
|
|
-
|
|
84
|
|
- to use Visual C++ on Win32, type: `make setup visualc'
|
|
85
|
|
- to use Borland C++ on Win32, type `make setup bcc32'
|
|
86
|
|
- to use Watcom C++ on Win32, type `make setup watcom'
|
|
87
|
|
- to use Intel C++ on Win32, type `make setup intelc'
|
|
88
|
|
- to use LCC-Win32 on Win32, type: `make setup lcc'
|
|
89
|
|
- to use Watcom C++ on OS/2, type `make setup watcom'
|
|
90
|
|
- to use VisualAge C++ on OS/2, type `make setup visualage'
|
|
91
|
|
-
|
|
92
|
|
- The <compiler> name to use is platform-dependent. The list of
|
|
93
|
|
- available compilers for your system is available in the file
|
|
94
|
|
- `builds/<system>/detect.mk'.
|
|
95
|
|
-
|
|
96
|
|
- If you are satisfied by the new configuration summary, skip to
|
|
97
|
|
- step 5.
|
|
98
|
|
-
|
|
99
|
|
-
|
|
100
|
|
- 3a. Use clang instead of gcc
|
|
101
|
|
- ----------------------------
|
|
102
|
|
-
|
|
103
|
|
- The `clang' compiler can use FreeType's setup for `gcc'; it is
|
|
104
|
|
- sufficient to set the `CC' variable, for example
|
|
105
|
|
-
|
|
106
|
|
- make CC=clang
|
|
107
|
|
-
|
|
108
|
|
-
|
|
109
|
|
- 3b. Compiling with a C++ compiler
|
|
110
|
|
- ---------------------------------
|
|
111
|
|
-
|
|
112
|
|
- FreeType can be built with a C++ compiler, for example
|
|
113
|
|
-
|
|
114
|
|
- make CC="g++"
|
|
115
|
|
-
|
|
116
|
|
- If `clang++' should be used it is necessary to also override the
|
|
117
|
|
- `ANSIFLAGS' variable:
|
|
118
|
|
-
|
|
119
|
|
- make CC="clang++" ANSIFLAGS=""
|
|
120
|
|
-
|
|
121
|
|
-
|
|
122
|
|
- 4. Configure the build system for an unknown platform/compiler
|
|
123
|
|
- --------------------------------------------------------------
|
|
124
|
|
-
|
|
125
|
|
- The auto-detection/setup phase of the build system copies a file
|
|
126
|
|
- to the current directory under the name `config.mk'.
|
|
127
|
|
-
|
|
128
|
|
- For example, on OS/2+gcc, it would simply copy
|
|
129
|
|
- `builds/os2/os2-gcc.mk' to `./config.mk'.
|
|
130
|
|
-
|
|
131
|
|
- If for some reason your platform isn't correctly detected, copy
|
|
132
|
|
- manually the configuration sub-makefile to `./config.mk' and go to
|
|
133
|
|
- step 5.
|
|
134
|
|
-
|
|
135
|
|
- Note that this file is a sub-Makefile used to specify Make
|
|
136
|
|
- variables for compiler and linker invocation during the build.
|
|
137
|
|
- You can easily create your own version from one of the existing
|
|
138
|
|
- configuration files, then copy it to the current directory under
|
|
139
|
|
- the name `./config.mk'.
|
|
140
|
|
-
|
|
141
|
|
-
|
|
142
|
|
- 5. Build the library
|
|
143
|
|
- --------------------
|
|
144
|
|
-
|
|
145
|
|
- The auto-detection/setup phase should have copied a file in the
|
|
146
|
|
- current directory, called `./config.mk'. This file contains
|
|
147
|
|
- definitions of various Make variables used to invoke the compiler
|
|
148
|
|
- and linker during the build. [It has also generated a file called
|
|
149
|
|
- `ftmodule.h' in the objects directory (which is normally
|
|
150
|
|
- `<toplevel>/objs/'); please read the file `docs/CUSTOMIZE' for
|
|
151
|
|
- customization of FreeType.]
|
|
152
|
|
-
|
|
153
|
|
- To launch the build, simply invoke GNU Make again: The top
|
|
154
|
|
- Makefile will detect the configuration file and run the build with
|
|
155
|
|
- it. If you have used variables in step 3, you must use the same
|
|
156
|
|
- variables here, too.
|
|
157
|
|
-
|
|
158
|
|
-
|
|
159
|
|
- Final note
|
|
160
|
|
-
|
|
161
|
|
- The above instructions build a _statically_ linked library of the
|
|
162
|
|
- font engine in the `objs' directory. On Windows, you can build a
|
|
163
|
|
- DLL either with MinGW (within an MSYS shell, following the
|
|
164
|
|
- instructions in `INSTALL.UNIX'), or you use one of the Visual C++
|
|
165
|
|
- project files; see the subdirectories of `builds/windows'. For
|
|
166
|
|
- everything else, you are on your own, and you might follow the
|
|
167
|
|
- instructions in `INSTALL.ANY' to create your own Makefiles.

-This document contains instructions on how to build the FreeType
|
|
2
|
|
-library on Unix systems. This also works for emulations like Cygwin
|
|
3
|
|
-or MSys on Win32:
|
|
4
|
|
-
|
|
5
|
|
-
|
|
6
|
|
- 1. Ensure that you are using GNU Make
|
|
7
|
|
- -------------------------------------
|
|
8
|
|
-
|
|
9
|
|
- The FreeType build system _exclusively_ works with GNU Make. You
|
|
10
|
|
- will not be able to compile the library with the instructions
|
|
11
|
|
- below using any other alternative (including BSD Make).
|
|
12
|
|
-
|
|
13
|
|
- Check that you have GNU make by running the command:
|
|
14
|
|
-
|
|
15
|
|
- make -v
|
|
16
|
|
-
|
|
17
|
|
- This should dump some text that begins with:
|
|
18
|
|
-
|
|
19
|
|
- GNU Make <version number>
|
|
20
|
|
- Copyright (C) <year> Free Software Foundation Inc.
|
|
21
|
|
-
|
|
22
|
|
- Note that version 3.81 or higher is *required* or the build will
|
|
23
|
|
- fail.
|
|
24
|
|
-
|
|
25
|
|
- It is also fine to have GNU Make under another name (e.g. 'gmake')
|
|
26
|
|
- if you use the MAKE variable as described below.
|
|
27
|
|
-
|
|
28
|
|
- As a special exception, 'makepp' can also be used to build
|
|
29
|
|
- FreeType 2. See the file docs/MAKEPP for details.
|
|
30
|
|
-
|
|
31
|
|
- For builds with `cmake' please check file `CMakeLists.txt'; this
|
|
32
|
|
- is a contributed file not directly supported by the FreeType team.
|
|
33
|
|

|
|
34
|
|
-
|
|
35
|
|
- 2. Regenerate the configure script if needed
|
|
36
|
|
- --------------------------------------------
|
|
37
|
|
-
|
|
38
|
|
- This only applies if you are building a git snapshot or checkout,
|
|
39
|
|
- *not* if you grabbed the sources of an official release.
|
|
40
|
|
-
|
|
41
|
|
- You need to invoke the `autogen.sh' script in the top-level
|
|
42
|
|
- directory in order to create the `configure' script for your
|
|
43
|
|
- platform. Normally, this simply means typing:
|
|
44
|
|
-
|
|
45
|
|
- sh autogen.sh
|
|
46
|
|
-
|
|
47
|
|
- In case of problems, you may need to install or upgrade Automake,
|
|
48
|
|
- Autoconf or Libtool. See `README.git' in the top-level directory
|
|
49
|
|
- for more information.
|
|
50
|
|
-
|
|
51
|
|
-
|
|
52
|
|
- 3. Build and install the library
|
|
53
|
|
- --------------------------------
|
|
54
|
|
-
|
|
55
|
|
- Say
|
|
56
|
|
-
|
|
57
|
|
- ./configure --help
|
|
58
|
|
-
|
|
59
|
|
- to see the list of possible configuration options and important
|
|
60
|
|
- environment variables. The ./configure script will detect some
|
|
61
|
|
- prerequisite system libraries (libpng, brotli, etc.) if their
|
|
62
|
|
- headers are available at the default locations.
|
|
63
|
|
-
|
|
64
|
|
- The following should work on all Unix systems where the `make'
|
|
65
|
|
- command invokes GNU Make:
|
|
66
|
|
-
|
|
67
|
|
- ./configure [options]
|
|
68
|
|
- make
|
|
69
|
|
- make install (as root)
|
|
70
|
|
-
|
|
71
|
|
- The default installation path is `/usr/local'. It can be changed
|
|
72
|
|
- with the `--prefix=<path>' option. Example:
|
|
73
|
|
-
|
|
74
|
|
- ./configure --prefix=/usr
|
|
75
|
|
-
|
|
76
|
|
- When using a different command to invoke GNU Make, use the MAKE
|
|
77
|
|
- variable. For example, if `gmake' is the command to use on your
|
|
78
|
|
- system, do something like:
|
|
79
|
|
-
|
|
80
|
|
- MAKE=gmake ./configure [options]
|
|
81
|
|
- gmake
|
|
82
|
|
- gmake install (as root)
|
|
83
|
|
-
|
|
84
|
|
- If this still doesn't work, there must be a problem with your
|
|
85
|
|
- system (e.g., you are using a very old version of GNU Make).
|
|
86
|
|
-
|
|
87
|
|
- For library identification, FreeType's `configure' script uses the
|
|
88
|
|
- `pkg-config' interface: Assuming it needs library `foo', it calls
|
|
89
|
|
- the `pkg-config' program to find information on library `foo',
|
|
90
|
|
- which in turn looks for a `foo.pc' file installed at the system.
|
|
91
|
|
- Some platforms, however, don't come with `pkg-support'; you then
|
|
92
|
|
- have to use environment variables as described by `configure
|
|
93
|
|
- --help'. Example:
|
|
94
|
|
-
|
|
95
|
|
- LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \
|
|
96
|
|
- LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \
|
|
97
|
|
- configure ...
|
|
98
|
|
-
|
|
99
|
|
- It is possible to compile FreeType in a different directory.
|
|
100
|
|
- Assuming the FreeType source files in directory `/src/freetype' a
|
|
101
|
|
- compilation in directory `foo' works as follows:
|
|
102
|
|
-
|
|
103
|
|
- cd foo
|
|
104
|
|
- /src/freetype/configure [options]
|
|
105
|
|
- make
|
|
106
|
|
- make install
|
|
107
|
|
-
|
|
108
|
|
-
|
|
109
|
|
- 3.1 Interdependency with HarfBuzz
|
|
110
|
|
- .................................
|
|
111
|
|
-
|
|
112
|
|
- Note that there is a chicken-and-egg problem currently since the
|
|
113
|
|
- HarfBuzz library (used by the auto-hinter to improve support of
|
|
114
|
|
- OpenType fonts) depends on FreeType, which can be solved as
|
|
115
|
|
- follows in case HarfBuzz is not yet installed on your system.
|
|
116
|
|
-
|
|
117
|
|
- 1. Call FreeType's `configure' script with option
|
|
118
|
|

|
+ The git repository doesn't contain pre-built configuration scripts for

+ UNIXish platforms. To generate them say
|
|
|
95
|
+
|
|
|
96
|
+ sh autogen.sh
|
|
|
97
|
+
|
|
|
98
|
+ which in turn depends on the following packages:
|
|
|
99
|
+
|
|
|
100
|
+ automake (1.10.1)
|
|
|
101
|
+ libtool (2.2.4)
|
|
|
102
|
+ autoconf (2.62)
|
|
|
103
|
+
|
|
|
104
|
+ The versions given in parentheses are known to work. Newer versions
|
|
|
105
|
+ should work too, of course. Note that `autogen.sh` also sets up
|
|
|
106
|
+ proper file permissions for the `configure` and auxiliary scripts.
|
|
|
107
|
+
|
|
|
108
|
+ The `autogen.sh` script checks whether the versions of the above three
|
|
|
109
|
+ tools match the numbers above. Otherwise it will complain and suggest
|
|
|
110
|
+ either upgrading or using environment variables to point to more
|
|
|
111
|
+ recent versions of the required tools.
|
|
|
112
|
+
|
|
|
113
|
+ Note that `aclocal` is provided by the 'automake' package on Linux,
|
|
|
114
|
+ and that `libtoolize` is called `glibtoolize` on Darwin (OS X).

|

|
117
|
+## E. Alternative build methods
|
|
|
118
|
+
|
|
|
119
|
+ For static builds that don't use platform-specific optimizations, no
|
|
|
120
|
+ configure script is necessary at all; saying
|
|
|
121
|
+
|
|
|
122
|
+ make setup ansi
|
|
|
123
|
+ make
|
|
|
124
|
+
|
|
|
125
|
+ should work on all platforms that have GNU `make` (or `makepp`).
|
|
|
126
|
+
|
|
|
127
|
+ A build with `cmake` or `meson` can be done directly from the git
|
|
|
128
|
+ repository. However, if you want to use the `FT_DEBUG_LOGGING` macro
|
|
|
129
|
+ (see file [docs/DEBUG][DEBUG] for more information) it is currently mandatory
|
|
|
130
|
+ to execute `autogen.sh` in advance; this script clones the 'dlg' git
|
|
|
131
|
+ submodule and copies some files into FreeType's source tree.

|
+If you want to test FreeType on arm devices, compiling it on an Android
|
|
|
4
|
+phone is one of the easiest ways.
|
|
|

|
+
|
|
|
6
|
+## 1. Compiling FreeType
|
|
|
7
|
+
|
|
|
8
|
+1. Install and open termux
|
|
|
9
|
+
|
|
|
10
|
+2. Update termux packages using:
|
|
|
11
|
+
|
|
|
12
|
+ ```bash
|
|
|
13
|
+ pkg update
|
|
|
14
|
+ pkg upgrade
|
|
|
15
|
+ ```
|
|
|
16
|
+ Select `y` if any configuration changes are asked
|
|
|
17
|
+
|
|
|
18
|
+3. Install `git`:
|
|
|
19
|
+
|
|
|
20
|
+ ```bash
|
|
|
21
|
+ pkg install git
|
|
|
22
|
+ ```
|
|
|
23
|
+4. Install packages required for compilation:
|
|
|
24
|
+
|
|
|
25
|
+ ```bash
|
|
|
26
|
+ pkg install automake autoconf libtool make clang binutils
|
|
|
27
|
+ ```
|
|
|
28
|
+
|
|
|
29
|
+5. Clone FreeType's git repository:
|
|
|
30
|
+
|
|
|
31
|
+ ```bash
|
|
|
32
|
+ git clone https://gitlab.freedesktop.org/freetype/freetype.git
|
|
|
33
|
+ ```
|
|
|
34
|
+
|
|
|
35
|
+6. Enter into the source directory:
|
|
|
36
|
+
|
|
|
37
|
+ ```
|
|
|
38
|
+ cd freetype/
|
|
|
39
|
+ ```
|
|
|
40
|
+
|
|
|
41
|
+7. Now you can compile FreeType according to [INSTALL_UNIX.md]:
|
|
|
42
|
+
|
|
|
43
|
+ ```bash
|
|
|
44
|
+ ./autogen.sh
|
|
|
45
|
+ ./configure
|
|
|
46
|
+ make -j$(nproc)
|
|
|
47
|
+ ```
|
|
|
48
|
+ The compiled binaries can be accessed under `objs/.libs`
|
|
|
49
|
+
|
|
|
50
|
+## 2. Compiling FreeType Demo programs
|
|
|
51
|
+If you need to test your changes you may want to use ft-demo
|
|
|
52
|
+programs. They can be compiled and run by follwing these steps:
|
|
|
53
|
+
|
|
|
54
|
+1. First compile FreeType using the steps above.
|
|
|
55
|
+
|
|
|
56
|
+2. Clone FreeType demos adjacent to the `freetype/` directory:
|
|
|
57
|
+
|
|
|
58
|
+ ```bash
|
|
|
59
|
+ git clone https://gitlab.freedesktop.org/freetype/freetype-demos.git
|
|
|
60
|
+ ```
|
|
|
61
|
+ i.e. If you can access FreeType repo under `~/freetype`, you should
|
|
|
62
|
+ be able to access `~/freetype-demos`.
|
|
|
63
|
+
|
|
|
64
|
+3. Enter into the ft-demos directory:
|
|
|
65
|
+
|
|
|
66
|
+ ```bash
|
|
|
67
|
+ cd freetype-demos
|
|
|
68
|
+ ```
|
|
|
69
|
+
|
|
|
70
|
+4. Compile the programs:
|
|
|
71
|
+
|
|
|
72
|
+ ```bash
|
|
|
73
|
+ make
|
|
|
74
|
+ ```
|
|
|
75
|
+
|
|
|
76
|
+5. The compiled binaries can be accessed and executed under `bin/` like:
|
|
|
77
|
+
|
|
|
78
|
+ ```bash
|
|
|
79
|
+ cd bin
|
|
|
80
|
+ ./ftlint
|
|
|

|
+ ```

|
|
|
4
|
+library on Unix systems, for example, building binaries for Linux/MIPS
|
|
|
5
|
+on FreeBSD/i386. Before reading this document, please consult the
|
|
|
6
|
+file [INSTALL_UNIX.md] for required tools and the basic self-building
|
|
|

|
+## 1. Required Tools
|
|
|
11
|
+
|
|
|
12
|
+ For self-building the FreeType library on a Unix system, GNU Make
|
|
|
13
|
+ 3.81 or newer is required. [INSTALL_UNIX.md contains hints how to
|
|
|
14
|
+ check the installed `make`.
|
|
|
15
|
+
|
|
|
16
|
+ The GNU C compiler to cross-build the target system is required.
|
|
|
17
|
+ Currently, using a non-GNU cross compiler is untested. The cross
|
|
|
18
|
+ compiler is expected to be installed with a system prefix. For
|
|
|
19
|
+ example, if your building system is FreeBSD/i386 and the target
|
|
|
20
|
+ system is Linux/MIPS, the cross compiler should be installed with
|
|
|
21
|
+ the name `mips-ip22-linuxelf-gcc`.
|
|
|
22
|
+
|
|
|
23
|
+ A C compiler for a self-build is required also, to build a tool
|
|
|
24
|
+ (`apinames`) that is executed during the build procedure. Non-GNU
|
|
|
25
|
+ self compilers are acceptable, but such a setup is untested.
|
|
|

|
|
|
28
|
+## 2. Configuration
|
|
|
29
|
+
|
|
|
30
|
+ ### 2.1 Building and target system
|
|
|
31
|
+
|
|
|
32
|
+ To configure a cross-build, the options `--host=<system>` and
|
|
|
33
|
+ `--build=<system>` must be passed to the `configure` script.
|
|
|
34
|
+ For example, if your build system is FreeBSD/i386 and the target
|
|
|
35
|
+ system is Linux/MIPS, say
|
|
|
36
|
+
|
|
|
37
|
+ ```bash
|
|
|
38
|
+ ./configure \
|
|
|
39
|
+ --build=i386-unknown-freebsd \
|
|
|
40
|
+ --host=mips-ip22-linuxelf \
|
|
|
41
|
+ [other options]
|
|
|
42
|
+ ```
|
|
|
43
|
+
|
|
|
44
|
+ It should be noted that `--host=<system>` specifies the system
|
|
|
45
|
+ where the built binaries will be executed, not the system where
|
|
|
46
|
+ the build actually happens. Older versions of GNU autoconf use
|
|
|
47
|
+ the option pair `--host=` and `--target=`. This is broken and
|
|
|
48
|
+ doesn't work. Similarly, an explicit CC specification like
|
|
|
49
|
+
|
|
|
50
|
+ ```bash
|
|
|
51
|
+ env CC=mips-ip22-linux-gcc ./configure # BAD
|
|
|
52
|
+ ```
|
|
|
53
|
+ or
|
|
|
54
|
+
|
|
|
55
|
+ ```bash
|
|
|
56
|
+ env CC=/usr/local/mips-ip22-linux/bin/gcc ./configure # BAD
|
|
|
57
|
+ ```
|
|
|
58
|
+
|
|
|
59
|
+ doesn't work either; such a configuration confuses the
|
|
|
60
|
+ `configure` script while trying to find the cross and native C
|
|
|
61
|
+ compilers.
|
|
|
62
|
+
|
|
|
63
|
+
|
|
|
64
|
+ ### 2.2. The prefix to install FreeType2
|
|
|
65
|
+
|
|
|
66
|
+ Setting `--prefix=<prefix>` properly is important. The prefix
|
|
|
67
|
+ to install FreeType2 is written into the `freetype-config`
|
|
|
68
|
+ script and `freetype2.pc` configuration file.
|
|
|
69
|
+
|
|
|
70
|
+ If the built FreeType 2 library is used as a part of the
|
|
|
71
|
+ cross-building system, the prefix is expected to be different
|
|
|
72
|
+ from the self-building system. For example, a configuration
|
|
|
73
|
+ with `--prefix=/usr/local` installs binaries into the
|
|
|
74
|
+ system-wide `/usr/local` directory, which then can't be executed
|
|
|
75
|
+ due to the incorrect architecture. This causes confusion in
|
|
|
76
|
+ configuration of all applications that use FreeType2. Instead,
|
|
|
77
|
+ use a prefix to install the cross-build into a separate system
|
|
|
78
|
+ tree, for example, `--prefix=/usr/local/mips-ip22-linux/`.
|
|
|
79
|
+
|
|
|
80
|
+ On the other hand, if the built FreeType 2 library is used as a
|
|
|
81
|
+ part of the target system, the prefix to install should reflect
|
|
|
82
|
+ the file system structure of the target system.
|
|
|
83
|
+
|
|
|
84
|
+
|
|
|
85
|
+ ### 2.3. Library dependencies
|
|
|
86
|
+
|
|
|
87
|
+ FreeType normally depends on external libraries like `libpng` or
|
|
|
88
|
+ `libharfbuzz`. The easiest case is to deactivate all such
|
|
|
89
|
+ dependencies using the `--without-XXX` configuration options.
|
|
|
90
|
+ However, if you want to use those libraries, you should ensure
|
|
|
91
|
+ that they are available both on the target system and as
|
|
|
92
|
+ (cross-compiled) libraries on the build system.
|
|
|
93
|
+
|
|
|
94
|
+ FreeType uses `pkg-config` to find most of the libraries; the
|
|
|
95
|
+ other libraries it links to are expected in the standard system
|
|
|
96
|
+ directories. Since the default pkg-config's meta-information
|
|
|
97
|
+ files (like `harfbuzz.pc`) of the build platform don't work, use
|
|
|
98
|
+ one of the two possible solutions below.
|
|
|
99
|
+
|
|
|
100
|
+ - Use pkg-config's meta-information files that are adjusted to
|
|
|
101
|
+ cross-compile and cross-link with the target platform's
|
|
|
102
|
+ libraries. Make sure those files are found before the build
|
|
|
103
|
+ system's default files. Example:
|
|
|
104
|
+ ```bash
|

|
150
|
+

151
|
+ As noted in section 2.2, FreeType2 is sometimes configured to be

|
152
|
+ installed into the system directory of the target system, and
|
|
|
153
|
+ should not be installed in the cross-building system. In such
|
|
|
154
|
+ cases, the make variable `DESTDIR` is useful to change the root

|
156
|
+
|
|
|

|
+This document contains instructions how to build the FreeType library
|
|
|
4
|
+on non-Unix systems with the help of GNU Make. Note that if you are
|
|
|
5
|
+running Cygwin or MinGW/MSYS in Windows, you should follow the
|
|
|
6
|
+instructions in the file [INSTALL_UNIX.md] instead.

|
+FreeType 2 includes a powerful and flexible build system that allows
|
|
|
10
|
+you to easily compile it on a great variety of platforms from the
|
|
|
11
|
+command line. To do so, just follow these simple instructions.
|
|
|
12
|
+
|
|
|
13
|
+## 1. Install GNU Make
|
|
|
14
|
+
|
|
|
15
|
+ The FreeType 2 build system relies on many features special to GNU
|
|
|
16
|
+ Make.
|
|
|
17
|
+
|
|
|
18
|
+ NEARLY ALL OTHER MAKE TOOLS FAIL, INCLUDING `BSD MAKE`, SO REALLY
|
|
|
19
|
+ INSTALL A RECENT VERSION OF GNU MAKE ON YOUR SYSTEM!
|
|
|
20
|
+
|
|
|
21
|
+ Note that make++, a make tool written in Perl, supports enough
|
|
|
22
|
+ features of GNU make to compile FreeType. See
|
|
|
23
|
+
|
|
|
24
|
+ https://makepp.sourceforge.net
|
|
|
25
|
+
|
|
|
26
|
+ for more information; you need version 2.0 or newer, and you must
|
|
|
27
|
+ pass option `--norc-substitution`.
|
|
|
28
|
+
|
|
|
29
|
+ Make sure that you are invoking GNU Make from the command line, by
|
|
|
30
|
+ typing something like:
|
|
|
31
|
+
|
|
|
32
|
+ make -v
|
|
|
33
|
+
|
|
|
34
|
+ to display its version number.
|
|
|
35
|
+
|
|
|
36
|
+ VERSION 3.81 OR NEWER IS NEEDED!
|
|
|
37
|
+
|
|
|
38
|
+
|
|
|
39
|
+## 2. Invoke `make`
|
|
|
40
|
+
|
|
|
41
|
+ Go to the root directory of FreeType 2, then simply invoke GNU
|
|
|
42
|
+ Make from the command line. This will launch the FreeType 2 host
|
|
|
43
|
+ platform detection routines. A summary will be displayed, for
|
|
|
44
|
+ example, on Win32.
|
|
|
45
|
+
|
|
|
46
|
+
|
|
|
47
|
+ FreeType build system -- automatic system detection
|
|
|
48
|
+
|
|
|
49
|
+ The following settings are used:
|
|
|
50
|
+
|
|
|
51
|
+ platform windows
|
|
|
52
|
+ compiler gcc
|
|
|
53
|
+ configuration directory .\builds\windows
|
|
|
54
|
+ configuration rules .\builds\windows\w32-gcc.mk
|
|
|
55
|
+
|
|
|
56
|
+ If this does not correspond to your system or settings please
|
|
|
57
|
+ remove the file 'config.mk' from this directory then read the
|
|
|
58
|
+ INSTALL file for help.
|
|
|
59
|
+
|
|
|
60
|
+ Otherwise, simply type 'make' again to build the library
|
|
|
61
|
+ or 'make refdoc' to build the API reference (the latter needs
|
|
|
62
|
+ Python >= 3.5).
|
|
|
63
|
+
|
|
|
64
|
+
|
|
|
65
|
+ If the detected settings correspond to your platform and compiler,
|
|
|
66
|
+ skip to step 5. Note that if your platform is completely alien to
|
|
|
67
|
+ the build system, the detected platform will be `ansi`.
|
|
|
68
|
+
|
|
|
69
|
+
|
|
|
70
|
+## 3. Configure the build system for a different compiler
|
|
|
71
|
+
|
|
|
72
|
+ If the build system correctly detected your platform, but you want
|
|
|
73
|
+ to use a different compiler than the one specified in the summary
|
|
|
74
|
+ (for most platforms, gcc is the default compiler), invoke GNU Make
|
|
|
75
|
+ with
|
|
|
76
|
+
|
|
|
77
|
+ ```
|
|
|
78
|
+ make setup <compiler>
|
|
|
79
|
+ ```
|
|
|
80
|
+
|
|
|
81
|
+ Examples:
|
|
|
82
|
+
|
|
|
83
|
+ to use Visual C++ on Win32, type: `make setup visualc`
|
|
|
84
|
+
|
|
|
85
|
+ to use Borland C++ on Win32, type `make setup bcc32`
|
|
|
86
|
+
|
|
|
87
|
+ to use Watcom C++ on Win32, type `make setup watcom`
|
|
|
88
|
+
|
|
|
89
|
+ to use Intel C++ on Win32, type `make setup intelc`
|
|
|
90
|
+
|
|
|
91
|
+ to use LCC-Win32 on Win32, type: `make setup lcc`
|
|
|
92
|
+
|
|
|
93
|
+ to use Watcom C++ on OS/2, type `make setup watcom`
|
|
|
94
|
+
|
|
|
95
|
+ to use VisualAge C++ on OS/2, type `make setup visualage`
|
|
|
96
|
+
|
|
|
97
|
+
|
|
|
98
|
+ The `<compiler>` name to use is platform-dependent. The list of
|
|
|
99
|
+ available compilers for your system is available in the file
|
|
|
100
|
+ `builds/<system>/detect.mk`.
|
|
|
101
|
+
|
|
|
102
|
+ If you are satisfied by the new configuration summary, skip to
|
|
|
103
|
+ step 5.
|
|
|
104
|
+
|
|
|
105
|
+
|
|
|
106
|
+ ### 3a. Use clang instead of gcc
|
|
|
107
|
+
|
|
|
108
|
+ The `clang` compiler can use FreeType's setup for `gcc`; it is
|
|
|
109
|
+ sufficient to set the `CC` variable, for example
|
|
|
110
|
+
|
|
|
111
|
+ make CC=clang
|
|
|
112
|
+
|
|
|
113
|
+
|
|
|
114
|
+ ### 3b. Compiling with a C++ compiler
|
|
|
115
|
+
|
|
|
116
|
+ FreeType can be built with a C++ compiler, for example
|
|
|
117
|
+
|
|
|
118
|
+ make CC="g++"
|
|
|
119
|
+
|
|
|
120
|
+ If `clang++` should be used it is necessary to also override the
|
|
|
121
|
+ `ANSIFLAGS` variable:
|
|
|
122
|
+
|
|
|
123
|
+ make CC="clang++" ANSIFLAGS=""
|
|
|
124
|
+
|
|
|
125
|
+
|
|
|
126
|
+## 4. Configure the build system for an unknown platform/compiler
|
|
|
127
|
+
|
|
|
128
|
+ The auto-detection/setup phase of the build system copies a file
|
|
|
129
|
+ to the current directory under the name `config.mk`.
|
|
|
130
|
+
|
|
|
131
|
+ For example, on OS/2+gcc, it would simply copy
|
|
|
132
|
+ `builds/os2/os2-gcc.mk` to `./config.mk`.
|
|
|
133
|
+
|
|
|
134
|
+ If for some reason your platform isn't correctly detected, copy
|
|
|
135
|
+ manually the configuration sub-makefile to `./config.mk` and go to
|
|
|
136
|
+ step 5.
|
|
|
137
|
+
|
|
|
138
|
+ Note that this file is a sub-Makefile used to specify Make
|
|
|
139
|
+ variables for compiler and linker invocation during the build.
|
|
|
140
|
+ You can easily create your own version from one of the existing
|
|
|
141
|
+ configuration files, then copy it to the current directory under
|
|
|
142
|
+ the name `./config.mk`.
|
|
|
143
|
+
|
|
|
144
|
+
|
|
|
145
|
+## 5. Build the library
|
|
|
146
|
+
|
|
|
147
|
+ The auto-detection/setup phase should have copied a file in the
|
|
|
148
|
+ current directory, called `./config.mk`. This file contains
|
|
|
149
|
+ definitions of various Make variables used to invoke the compiler
|
|
|
150
|
+ and linker during the build. [It has also generated a file called
|
|
|
151
|
+ `ftmodule.h` in the objects directory (which is normally
|
|
|
152
|
+ `<toplevel>/objs/`); please read the file [docs/CUSTOMIZE][CUSTOMIZE] for
|
|
|
153
|
+ customization of FreeType.]
|
|
|
154
|
+
|
|
|
155
|
+ To launch the build, simply invoke GNU Make again: The top
|
|
|
156
|
+ Makefile will detect the configuration file and run the build with
|
|
|
157
|
+ it. If you have used variables in step 3, you must use the same
|
|
|
158
|
+ variables here, too.
|
|
|
159
|
+
|
|
|
160
|
+
|
|
|
161
|
+Final note
|
|
|
162
|
+
|
|
|
163
|
+ The above instructions build a _statically_ linked library of the
|
|
|
164
|
+ font engine in the `objs` directory. On Windows, you can build a
|
|
|
165
|
+ DLL either with MinGW (within an MSYS shell, following the
|
|
|
166
|
+ instructions in `INSTALL.UNIX`), or you use one of the Visual C++
|
|
|
167
|
+ project files; see the subdirectories of `builds/windows`. For
|
|
|
168
|
+ everything else, you are on your own, and you might follow the
|
|
|
169
|
+ instructions in `INSTALL.ANY` to create your own Makefiles.

Starting with Mac OS X 10.5, gcc defaults the deployment target to
|
|
11
|
13
|
10.5. In previous versions of Mac OS X, this defaulted to 10.1. If
|
|
12
|
14
|
you want your built binaries to run only on 10.5, this change does not
|
|
13
|
15
|
concern you. If you want them to also run on older versions of Mac
|
|
14
|
16
|
OS X, then you must either set the MACOSX_DEPLOYMENT_TARGET
|
|
15
|
|
-environment variable or pass `-mmacosx-version-min' to gcc. You
|
|
|
17
|
+environment variable or pass `-mmacosx-version-min` to gcc. You
|
|
16
|
18
|
should specify the oldest version of Mac OS you want the code to run
|
|
17
|
19
|
on. For example, if you use Bourne shell:
|
|
18
|
20
|
|
|
|
21
|
+```bash
|
|
19

|

|
+
|
|
|
6
|
+## 1. Ensure that you are using GNU Make
|
|
|
7
|
+
|
|
|
8
|
+ The FreeType build system _exclusively_ works with GNU Make. You
|
|
|
9
|
+ will not be able to compile the library with the instructions
|
|
|
10
|
+ below using any other alternative (including BSD Make).
|
|
|
11
|
+
|
|
|
12
|
+ Check that you have GNU make by running the command:
|
|
|
13
|
+ ```bash
|
|
|
14
|
+ make -v
|
|
|
15
|
+ ```
|
|
|
16
|
+
|
|
|
17
|
+ This should dump some text that begins with:
|
|
|
18

+
|
|

|
|
|
21
|
+
|
|
|
22
|
+ Note that version 3.81 or higher is *required* or the build will
|
|
|
23
|
+ fail.
|
|
|
24
|
+
|
|
|
25
|
+ It is also fine to have GNU Make under another name (e.g. 'gmake')
|
|
|
26
|
+ if you use the MAKE variable as described below.
|
|
|
27
|
+
|
|
|
28
|
+ As a special exception, 'makepp' can also be used to build
|
|
|
29
|
+ FreeType 2. See the file `docs/MAKEPP` for details.

|
+## 2. Regenerate the configure script if needed
|
|
|
36
|
+
|
|
|
37
|
+ This only applies if you are building a git snapshot or checkout,
|
|
|
38
|
+ *not* if you grabbed the sources of an official release.
|
|
|
39
|
+
|
|
|
40
|
+ You need to invoke the `autogen.sh` script in the top-level
|
|
|
41
|
+ directory in order to create the `configure` script for your
|
|
|
42
|
+ platform. Normally, this simply means typing:
|
|
|
43
|
+ ```bash
|
|
|
44
|
+ sh autogen.sh
|
|
|
45
|
+ ```
|
|
|
46
|
+
|
|
|
47
|
+ In case of problems, you may need to install or upgrade Automake,
|
|
|
48
|
+ Autoconf or Libtool. See [INSTALL.md] for more information.
|
|
|
49
|
+
|
|
|
50
|
+
|
|
|
51
|
+## 3. Build and install the library
|
|
|
52
|
+
|
|
|
53
|
+ Say
|
|
|
54
|
+ ```bash
|
|
|
55
|
+ ./configure --help
|
|
|
56
|
+ ```
|
|
|
57
|
+
|
|
|
58
|
+ to see the list of possible configuration options and important
|
|
|
59
|
+ environment variables. The `./configure` script will detect some
|
|
|
60
|
+ prerequisite system libraries (libpng, brotli, etc.) if their
|
|
|
61
|
+ headers are available at the default locations.
|
|
|
62
|
+
|
|
|
63
|
+ The following should work on all Unix systems where the `make`
|
|
|
64
|
+ command invokes GNU Make:
|
|
|
65
|
+ ```bash
|
|
|
66
|
+ ./configure [options]
|
|
|
67
|
+ make
|
|
|
68
|
+ make install (as root)
|
|
|
69
|
+ ```
|
|
|
70
|
+
|
|
|
71
|
+ The default installation path is `/usr/local`. It can be changed
|
|
|
72
|
+ with the `--prefix=<path>` option. Example:
|
|
|
73
|
+ ```bash
|
|
|
74
|
+ ./configure --prefix=/usr
|
|
|
75
|
+ ```
|
|
|
76
|
+
|
|
|
77
|
+ When using a different command to invoke GNU Make, use the MAKE
|
|
|
78
|
+ variable. For example, if `gmake` is the command to use on your
|
|
|
79
|
+ system, do something like:
|
|
|
80
|
+ ```bash
|
|
|
81
|
+ MAKE=gmake ./configure [options]
|
|
|
82
|
+ gmake
|
|
|
83
|
+ gmake install (as root)
|
|
|
84
|
+ ```
|
|
|
85
|
+
|
|
|
86
|
+ If this still doesn't work, there must be a problem with your
|
|
|
87
|
+ system (e.g., you are using a very old version of GNU Make).
|
|
|
88
|
+
|
|
|
89
|
+ For library identification, FreeType's `configure` script uses the
|
|
|
90
|
+ `pkg-config` interface: Assuming it needs library `foo`, it calls
|
|
|
91
|
+ the `pkg-config` program to find information on library `foo`,
|
|
|
92
|
+ which in turn looks for a `foo.pc` file installed at the system.
|
|
|
93
|
+ Some platforms, however, don't come with `pkg-support`; you then
|
|
|
94
|
+ have to use environment variables as described by `configure
|
|
|
95
|
+ --help`. Example:
|
|
|
96
|
+ ```bash
|
|
|
97
|
+ LIBPNG_CFLAGS="-I/path/to/libpng/include/directory" \
|
|
|
98
|
+ LIBPNG_LIBS="-L/path/to/libpng/lib/directory" \
|
|
|
99
|
+ configure ...
|
|
|
100
|
+ ```
|
|
|
101
|
+ It is possible to compile FreeType in a different directory.
|
|
|
102
|
+ Assuming the FreeType source files in directory `/src/freetype` a
|
|
|
103
|
+ compilation in directory `foo` works as follows:
|
|
|
104
|
+ ```bash
|
|
|
105
|
+ cd foo
|
|
|
106
|
+ /src/freetype/configure [options]
|
|
|
107
|
+ make
|
|
|
108
|
+ make install
|
|
|
109
|
+ ```
|
|
|

+
|
|
|
111

+
|

|
112
|
+ ### 3.1 Interdependency with HarfBuzz
|
|
|
113
|
+
|
|
|
114
|
+ Note that there is a chicken-and-egg problem currently since the
|
|
|
115
|
+ HarfBuzz library (used by the auto-hinter to improve support of
|
|
|
116
|
+ OpenType fonts) depends on FreeType, which can be solved as
|
|
|
117
|
+ follows in case HarfBuzz is not yet installed on your system.
|
|
|
118
|
+
|
|
|
119
|
+ 1. Call FreeType's `configure` script with option
|
|
|
120
|
+ `--without-harfbuzz`, then compile and install FreeType.
|
|
|
121
|
+
|
|
|
122
|
+ 2. Compile and install HarfBuzz.
|
|
|
123
|
+
|
|
|
124
|
+ 3. Call FreeType's `configure` script without option
|
|
|
125
|
+ `--without-harfbuzz` (after executing `make distclean`), then
|
|
|
126
|
+ compile and install FreeType again.

|
+FreeType follows a modular architecture, i.e. all the features are
|
|
|
4
|
+implemented as separate modules. There are separate modules for
|
|
|
5
|
+rasterizers, font parsers, hinting etc. located under the `src/` directory.
|
|
|
6
|
+
|
|
|
7
|
+(See https://freetype.org/freetype2/docs/design/design-5.html)
|
|
|
8
|
+
|
|
|
9
|
+To add new features you have to either modify the existing modules or
|
|
|
10
|
+add a new module to FreeType.
|
|
|
11
|
+
|
|
|
12
|
+## Adding a new module to FreeType
|
|
|
13
|
+
|
|
|
14
|
+Suppose we want to add a new module "example" to FreeType:
|
|
|
15
|
+
|
|
|
16
|
+1. Create a directory under `src/` having the same name as the module.
|
|
|
17
|
+ i.e. `src/example/`
|
|
|
18
|
+
|
|
|
19
|
+2. Add source files under src/example having `#define FT_MAKE_OPTION_SINGLE_OBJECT`
|
|
|
20
|
+ which includes the other files to create the module.
|
|
|
21
|
+
|
|
|
22
|
+ (See `src/sdf/sdf.c` for reference)
|
|
|
23
|
+
|
|
|
24
|
+3. Add the module to `include/freetype/config/ftmodule.h` according to whether
|
|
|
25
|
+ it is a renderer, font driver or another module like:
|
|
|
26
|
+
|
|
|
27
|
+ ```C
|
|
|
28
|
+ FT_USE_MODULE( FT_Renderer_Class, ft_example_renderer_class )
|
|
|
29
|
+ ```
|
|
|
30
|
+
|
|
|
31
|
+4. Add the module to `modules.cfg` in the toplevel directory:
|
|
|
32
|
+ ```
|
|
|
33
|
+ RASTER_MODULES += example
|
|
|
34
|
+ ```
|
|
|
35
|
+
|
|
|
36
|
+5. Under `src/example` add `module.mk` and `rules.mk` files to enable compilation
|
|
|
37
|
+ with `make`. (See `src/smooth/rules.mk` for reference).
|
|
|
38
|
+
|
|
|
39
|
+6. Now you can simply compile by using `make` in the toplevel directory and the module
|
|
|
40
|
+ should compile.
|
|
|
41
|
+
|
|
|
42
|
+ You can check out pre-existing modules for reference under `src/` |
