I'm having trouble compiling DevIL. I manage to configure it the way I want (without directx and with the OpenGL utiliies), but when I give the "make" command I get this error:

"error: invalid argument '-std=gnu99' not allowed with 'C++/ObjC++'

make[1]: *** [libIL_la-il_exr.lo] Error 1

make: *** [all-recursive] Error 1"

After some googling, I found that the error means that the computer is trying to compile C++ code with a plain C compiler (and that makes sense that it wouldn't work). However I couldn't find any solutions on how to correct it.

Is there a way to solve this or is it a problem only the lib ray developers can address?
