I have change the original glext.h files (version 17) present in the directory /usr/include/GL with the last version 22 and all my problems are resolved except with the extension GL_ARB_multitexture witch the use is really different that others extensions but this isn’t important.
But this solution don’t relary interesting me before it isn’t easy to other programmer to compile my code.
I think that the define of GL_GLEXT_LEGACY and the include of “./GL/glext.h” aren’t used and i don’t understand why …
