Re: Doubt about plotting on MAC OS X Catalina

[Elias Mårtenson]

There is no ldf on OSX if I'm not mistaken. I think you have to use otool.

Do note that OSX doesn't behave much like a Unix, and newer version are even more limited. 

You probably need to add the correct compiler flags manually since its possible autotools doesn't handle it right.

Hi,

try:

ldd apl

in the src directory to see if the apl binary find all its libraries. If not then you
need to configure and run ldconfig to tell the dynamic linker the place where
the shared libraries can be found. This is fairly platform dependant. It has no
relation to the header files (they are no longer needed after successful compilation).

I Have tried this.

Compiled and it worked finally de interpreter can find the X11 but now giving a segmentation fault:

Do you thing that adding the include files will help?

Hi,

too bad. How about /usr/local/include (and a bit olf luck that g++ knows it) ?

Hi,

so the headers are usable even though they don't exist. Interesting platform
that you have there. In that situation I would (recursively) copy the header files from
/opt/X11/include to /usr/include to make sure that they are found by both the
preprocessor and the compiler. If I remember correctly then apple does not
use the real g++ but a kind of emulation of it which might cause this kind of
problems.

Also have a look at config.log after ./configure; it tells you how the tests were compiled.

Hi,

I would at least expect something like

 CXXFLAGS="-I /opt/X11/include" ./configure

(if that is the directory where your header files live).

Hi Antonio,

For X11 and friend to work you need two different things:

1. header files, e.g. xcb.h, Xlib.h, etc.
2. library files, e.g. libxcb.so.1, libX11.so.6, etc.

These days libraries are often shipped in two different packages: one that
contains only the (shared) libraries and the other package contains the
corresponding header files. That second packages normally ends with "-dev".

For example (output from aptitude search libx11):

i   libx11-6                        - X11 client-side library
i   libx11-dev                      - X11 client-side library (development headers)

In your case the ./configure script cannot find the header files which means that either the  the -dev package
was not installed, or they were installed in an unusual place. In the latter case you can
tell ./configure where else to look, for example:

CXXFLAGS = -I /usr/somewhere_else ./configure [other configure options...]

Jürgen Sauermann

⎕PLOT is not available because one or more of its build prerequisites (in

particular libX11.so) was missing, or because it was explicitly

 disabled in ./configure.

But different from the first one, it was no libxcb library was found, I suspect that at this point I also need to change something in the configure in order to compile with X11

Hi again,

another thing that you may want to check is that your config.h (which is
generated by ./configure) contains the following lines:

/* Enable GNU extensions on systems that have them.  */
#ifndef _GNU_SOURCE
# define _GNU_SOURCE 1
#endif

Hi Antonio,

that seems to be an incompatibility between the commonly used libs and the Apple libs.
Nothing that I could (or should) do anything about in GNU APL. As far as I can see you could
probably remove the  POLLRDHUP without much harm so that the offending line reads:

pfd.events = POLLIN;
