OpenGL not found on my system!

[Redwolf]

Tried to compile Blender and d2x on Linux, neither would compile. Says I am missing openGL. I installed the headers AND the GLUT library, but it still doesn't trust me.

Exact error:

checking for IMG_ReadXPMFromArray in -lSDL_image... no
checking for main in -lGL... yes
checking for main in -lGLU... no
configure: error: GLU not found, --with-opengl cannot be used
redwolf@wolf:~/d2x-0.2.5$

Does anyone know how to fix this? I'm running Slackware 9 with emerde and the NVIDIA 5328 drivers (and yes, those headers are installed).

-edit- Crap, wxGTK won't install because of this either. I NEED OPENGL INSTALLED! How do I do this?

hello,
i assume you are running ./configure, try ./configure --help to get the command so you cna point to the exact location.

I can't point it to the exact location. wxGTK and Blender I'm compiling through emerde (portage clone) and d2x only gives me the --with-opengl option to work with.

The best way to do that would just be to compile glut again. But you do need the headers/libs etc installed. Are the /usr/X11R6/include/GL/glu.h and /usr/X11R6/include/GL/glut.h headers there?
Do locate glu and locate glut. Also, atm the blender makefiles are broken. You need a few patches to make them cleanly compile.

[Redwolf]

Ok, I checked. Both glu.h and glut.h are in the /usr/X11R6/include/GL folder. A little birdie once told me I need mesa installed too, but when I try to compile it with mesa, it says all packages that can satisfy the dependencies have been masked. I'll try unmerging and remerging glut now.

Ah, that happened to me once on Gentoo. There's a file (/usr/portage/profiles/package.mask) to edit that will rid you of the mask. The XFree ebuild takes care of mesa now (or should do) hence the mask
try re-emerging media-libs/glut (assuming emerde uses the same tree structure as portage)

[Redwolf]

One step ahead of ya.
I figured what the heck and did an emerde rsync. It notified me there was a new ver of portage. So I compiled that, and lo and behold. It now tells you what masks the package. So I looked at the packages.mask file and found that Cfree now takes care of mesa, and compiling it externally is dangerous. There was a new version of Xfree out anyway (ver r5), so I figured what the heck. It's been compiling for a while now. I figure after this I reinstall glut and try to compile wxgtk. Thanks for the help guys, I'll let you know how it goes!
