which backend/platform? it sounds like when your backend was compiled
either WGL or the GL/GLX libraries were not found.

Windows XP  (I installed GNUstep using gnustep-core-0.22.0-setup.exe and gnustep-system-0.22.0-setup.exe)

In which .a there is the glPixelFormatClass backend ?

When should I run configure ?
I wrote a GNUmakefile (for a small lib)

it seems that gnustep-core-0.22.0-setup.exe and gnustep-system-0.22.0-setup.exe  do not install" GNUstep Backend" package.

I will try to compile it by my self so, or any other explanation ?

Last question: do you how to remove the "-0" suffix that appears in the .dll file name ? (include $(GNUSTEP_MAKEFILES)/library.make)
 

I just compiled gnustep backend package (see config.log in attachement) and it installed files which were already installed with gnustep-core-0.22.0-setup.exe
(I mean libgnustep-back-016.dll and libgnustep-back-016.bundle etc..)

There is no .a associated to this dll so I think I have to activate something in my makefile (GNUMakefile)
Any idea ?
 
Thx
