It looks like I am also seeing this issue of compiling gl- render.cc on Mac. Has the fix propogated to the primary octave development branch? 

Jonathan

Yes


Hmm, OK, but I am getting this error:

I've started a fresh build and am now past liboctave and libcruft.
I can think two things that may be different (besides that I'm running 10.5.6). 

(1) I'm using Thomas' macro to make sure the OpenGL stuff is found.

http://www-old.cae.wisc.edu/pipermail/octave-maintainers/2009-February/010703.html
If you're not using it, give it a try. If you are, make sure you're not passing some OpenGL specifics to configure. 

When running configure I pass the following options ...
./configure --prefix=/sw FLIBS=/sw/lib/gcc4.3/lib/libgfortran.dylib F77=/sw/bin/gfortran --infodir='${prefix}/share/info' --mandir='$ {prefix}/share/man' --libexecdir='${prefix}/lib' -enable-shared - enable-dl --disable-static --without-mpi --with-hdf5 --with-fftw CPPFLAGS="-g -I/sw/include -I/sw/include/freetype2" FFLAGS="-g -ff2c" LDFLAGS="-L/sw/lib/fltk-aqua/lib -L/sw/lib -lfltk_gl -lfltk -lpthread" $blas 

where $blas points to vecLib and is defined as
blas='--with-lapack=-Wl,-framework,Accelerate,-dylib_file,/System/ Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ vecLib.framework/Versions/A/libLAPACK.dylib:/System/Library/Frameworks/ Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ libLAPACK.dylib --with-blas=-Wl,-framework,Accelerate,-dylib_file,/ System/Library/Frameworks/Accelerate.framework/Versions/A/Frameworks/ vecLib.framework/Versions/A/libBLAS.dylib:/System/Library/Frameworks/ Accelerate.framework/Versions/A/Frameworks/vecLib.framework/Versions/A/ libBLAS.dylib' 

Also notice I've setup things to work with the Fink package manager.

(2) I've also modified the tests for FTGL in configure.in

 707 #ifdef HAVE_FTGL_FTGL_H
 708 #ifdef HAVE_FTGL_UPPERCASE
 709 #include <FTGL/FTGL.h>
