[GEM-dev] pb with configure on new Gem install

[cyrille henry]

Hello,
after my main hard drive failure, i reinstall my system on a new hard drive.

so i'm still with ubuntu 10.04, and i'm now installing everything...

after a svn update (rev 4422) then ./autogen.sh, the ./configure finish with a :
configure: error: GL (headers) not found! you need openGL!!!

I did of course install everything that i think was related to openGL header.
moreover, the configure output this lines :
checking GL/gl.h usability... yes
checking GL/gl.h presence... yes
checking for GL/gl.h... yes
checking OpenGL/gl.h usability... no
checking OpenGL/gl.h presence... no
checking for OpenGL/gl.h... no

so i would imagine that gl.h is in GL folder...
the strange thing is that gem can compile and run correctly. so is it only this error that should not have to be displayed?

cheers,
Cyrille
