As it appears optional, I have disabled gzip support in the files used by 'configure'.
In 'ftoption.h' the precompiler directive is undefined:
#undef FT_CONFIG_OPTION_USE_ZLIB In 'modules.cfg' the gzip module addition is commented out:
Have you excluded ftgzip from the build?2014-06-13 11:42 GMT+02:00 Jeffrey Sheen <address@hidden>:Hi all,
I have successfully built a full version of freetype2, using the
freetype-ios project's Xcode project file. However, I am still unable to
build a minimal version of freetype2 using the 'configure' command line
method. Ideally, I would like to just build support for TrueType and
OpenType font formats.
Please find attached my 'ftoption.h' and 'modules.cfg' files, and the batch
script used to cross compile for iOS architectures (including the i386
simulator).
I get linker errors when trying to use the static library built with this
configuration. Specifically:
Undefined symbols for architecture i386:
"_FT_Gzip_Uncompress", referenced from:
_sfnt_init_face in libfreetype-ios+simulator.a(sfnt.o)
ld: symbol(s) not found for architecture i386
I can see that 'sfnt_init_face' calls 'FT_Gzip_Uncompress' in the source
code.
Although there is no dependency mentioned in the documentation, is it the
case that the TrueType or OpenType modules require Gzip support to be
enabled? I have disabled it in my build options, as I interpreted it as
being optional.
Any help is much appreciated.
Cheers,
Jeff.

Dear Werner and the wider freetype mailing list,
I just wanted to say that I fixed my OSX build environment by reinstalling
the latest distribution of the Xcode command line tools.
I have updated my StackOverflow question with this solution, so that
others with the same issue can resolve it without resorting to the mailing
list.
Thank you for your patience,
Jeff.

After contacting the owner of the freetype2-iphone git project, it seems
that he has the same problems building the library with Xcode. I have
decided to put that approach to one side for now, and to follow the
procedures detailed in INSTALL.UNIX and INSTALL.CROSS.
My execution of the `configure` script is currently not working with the
parameterisation suggested on StackOverflow, resulting in errors to do with
the `limits.h` and `assert.h` header files. However, this is specific to my
build environment, and not a general freetype2 question.
I have addressed the StackOverflow community to try to resolve this:

Many thanks for your quick response Werner.
This being my first foray with freetype2, I had indeed overlooked the
customisation of `ftmodule.h`.
After commenting out the modules corresponding to those `.c` files that
I had omitted from the compilation step, I rebuilt the product. I ended up
with a library of 3.2MB, as opposed to the previous build of 2.6Mb. I then
re-added it to my other, dependent Xcode project.
The first clean and build cycle of the dependent Xcode project yielded
the same linker errors, so there is still something awry. I will give it
another go in the morning.
Perhaps I will jettison my plan to build the freetype2 library with
Xcode altogether. There are some suggestions for a command line process that
I can attempt instead.

I notice that these errors contain the names of modules that I have
disabled, by removing their respective ".c" files from compilation
in the original "freetype2-ios" Xcode project.
Was there some other configuration required in that Xcode project,
in order to remove references to these disabled modules?
I guess that you've missed to update `ftmodule.h' to hold only the
modules you are going to use. Cf. `docs/CUSTOMIZE'.
