What exactly did not build with the standard Perl binary? OpenGL and
PDL work fine for me with the Apple-provided Perl, but I don't need
any fancy PDL options at the moment (such as the infamous PGPLOT, or
special Fortran libs).
OpenGL is supposed to use the standard OpenGL library in
/System/Library/Frameworks/OpenGL.framework/
that ships with every Mac. However, I'm beginning to suspect that we
still need X11 to be installed in order to build (I wouldn't notice
because I'd never touch a Mac without X11 :-).
Antonio, could you check whether you've got X11? Recent discussions
suggest that it's a standard part of the system since Leopard (before,
you had to download it separately), but perhaps it's an optional
install. In particular, you need the directory
/usr/X11/include/GL/
in order to build the Perl OpenGL module. BTW, do you have the latest
version of Leopard?
Best,
Stefan
PS: Chris, I remembered the reason why we're relying on X11 headers.
The gl.h and glu.h header files are present in the OpenGL framework,
but they're not contained in a GL/ subdirectory. If we just use
-I /System/Library/Frameworks/OpenGL.framework/Versions/Current/
Headers/
they aren't found by includes such as #include <GL/glu.h>. In order
to remove the dependency on X11 entirely, I suppose that we'd have to
wrap every relevant #include in an #ifdef. If you're willing to try
this, I can set the right include paths in Makefile.PL and see if it
works.
PPS: Antonio, if you want to get OpenGL / PDL up and running quickly,
you'll probably have to install X11. Just grab the latest version
from http://xquartz.macosforge.org/ and run the installer. But if you
can wait for a little while, we may be able to fix the OpenGL module
and it would be good to have someone (i.e. you) to confirm that it
actually builds without any prerequisites.
