GLEW: The OpenGL Extension Wrangler Library Latest Release: Download Last Update: 07-31-17 The OpenGL Extension Wrangler Library The OpenGL Extension Wrangler Library (GLEW) is a cross-platform open-source C/C extension loading library. GLEW provides efficient run-time mechanisms for determining which OpenGL extensions are supported on the target platform. OpenGL core and extension functionality is exposed in a single header file. GLEW has been tested on a variety of operating systems, including Windows, Linux, Mac OS X, FreeBSD, Irix, and Solaris. Downloads is distributed as source and precompiled binaries.
So I'm trying to bring a c project using Qt and OpenGL written and compiled on a Linux machine over to my Windows 7 machine at home, but I'm running into some difficulty. First I learned that some gl things (like GLTEXTURE0) were no longer defined because gl.h doesn't define them for windows. Also, the glext.h that I have does not define some functions like glActiveTexture.
Opengl Gltranslate
Both of these issues I found could be solved by bringing in a newer glext.h. My most immediate issue seems to be that I'm not bringing it in correctly. If I do: #define GLGLEXTLEGACY //should prevent old glext.h from being included #define GLGLEXTPROTOTYPES //should make glActiveTexture be defined #include #include 'glext.h' //local up-to-date glext.h #include then make tells me that I have undefined references to glActiveTexture. If I include QGLShaderProgram before glext.h, then I still have that problem, but make also warns me that I am redefining quite a few things that are defined in both QGLShaderProgram and glext, so I know the latter file is being included.
Any help would really be appreciated.
