[GRASS-user] Problems with OpenGL when compiling grass-6.4.0 on Mac OS X 10.5.4

[Elvis Dowson]

Hi William,
			Ok, I've taken your suggestions and tried it, but with identical  
results.

Here are my export option. I still get the same error without the -g  
option

export CFLAGS="-arch i386 -Os"
export CXXFLAGS="-arch i386 -Os"
export LDFLAGS="-arch i386 -Os"
export NAD2BIN=/Library/Frameworks/PROJ.framework/Programs/nad2bin

./configure --with-cxx --prefix=/Applications/GRASS --enable-macosx- 
app --with-x --with-cxx --with-opengl

I still get the same error

checking for gluBeginCurve in -lGLU... yes
checking for glXCreatePbuffer... no
configure: error: *** Unable to locate .

I have attached the config.log file here. Please note that configure  
command did not complete successfully. So, I haven't had a chance to  
run make, so the glXCreatePBuffer() error is in the config.log.

Any ideas on how I can resolve this or what might be causing this?



Best regards,

Elvis Dowson
