Re: Yet Another Plotting System for Octave

[Alexander Barth]

Marius,

In order to use libGL in OpenGL.framework, you have to set LDFLAGS before 
starting octave:

export 
LDFLAGS="-L/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries"

But maybe you need both libraries (in /usr/X11R6/lib/ and OpenGL.framework):

export LDFLAGS="-L/usr/X11R6/lib -lGL \
-L/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries"

Does this work?
