tan,log etc undefined reference
Author
Hi,
I was trying an openGL program in my system. When I tried to compile it I got the following errors
In libGL.so
undefined refrence to log,tan,floor etc. I do know that these are in math.h but I am not using it. Does anybody know why libGL.so giving such problems ?
I am using
MesaGL-3.0
Slackware 7.0 (like anyone is really bothere what I use)
Xfree 3.3.5(XF86_SVGA of 3.3.6)
Thank you
This is probably because the maths library isn''t linked into libgl itself. Try adding -lm to your linker command line to include it.

OpenGL certainly use maths and therefore needs the maths library linked.

Got it working, thank you.
This is what I have to type :-
cc filename.c -L/usr/lib -lGL -lGLU -lglut -L/usr/X11R6/lib -lXaw3d -lXxf86vm -lm
to compile an openGL app -ugh.
What did they do in X > 4.0 ? Linked all libraries to Xxf86vm ?

Those are for specific access to XF86 (XFree86) features
and are usually only valuable at the glX level.
This also limits your game to players using XF86 as their
X server (there are other X servers out there).
You might want to weigh the importance of the absolute need
of accessing XF86''s specific features in your game.
