Hello -
This is my first time using Inline.
I am trying to autowrap a C library called GLFW using Inline C (0.44) on Mac
OS X. GLFW is a very nice cross-platform OpenGL Framework. It deals with the
system issues and gets out of the way of your OpenGL app. Once I get this
working I plan on wrapping a few other libraries and making a decent framework
for developing games in Perl (ala PyGame for Python, but for 3D).
GLFW is built as a static library (libglfw.a) and is installed in the usual
location (/usr/local/lib). GCC finds it without issue. I am having an issue
however. To use OpenGL on Mac OS X "natively" (read: not through X11), one
must link using the -framework OpenGL option to GCC. You'll also end up
needing -framework AGL (Apple OpenGL) and -framework Carbon (GLFW uses Carbon
on Mac OS X).
So I have GLFW.pm at the moment compiling fine but failing to find certain
symbols that I find strange:
ld: Undefined symbols:
_main
_Perl_Gthr_key_ptr
_Perl_Isv_yes_ptr
_Perl_Tcurpad_ptr
_Perl_Tmarkstack_ptr_ptr
<snip>
Note that I have to use LDDLFLAGS for the -framework options and not LIBS as I
get "unknown option to LIBS: -framework" otherwise.
To make this easy for someone to help me, here's how to set this all up:
* Download and install GLFW on Mac OS X 10.3 (I am running 10.3.9)
http://easynews.dl.sourceforge.net/sourceforge/glfw/glfw-2.5.0.tar.bz2
make macosx-gcc
sudo mkdir -p /usr/local/lib
sudo cp libglfw.a /usr/local/lib
sudo ranlib /usr/local/lib/libglfw.a
sudo mkdir -p /usr/local/include/GL
sudo cp glfw.h /usr/local/include/GL
* Download my script (didn't want to make this email *too* big):
http://brianhammond.com/perl/GLFW.pm
http://brianhammond.com/perl/glfw-test.pl
* Try my script
perl -MInline=FORCE,NOISY ./glfw-test.pl
Let me know if you have any insights on this!
Thanks, Brian H.
PS - I'm not sure it matters but I am using Fink's perl in /sw/bin/perl which
is Perl 5.8.6
$ which perl
/sw/bin/perl
$ perl -v
This is perl, v5.8.6 built for darwin-thread-multi-2level
