How to use GLEW with MinGW [duplicate]

Question

I was trying to use glew32.lib file to link in my project, than I compile Glew source by myself to get glew.a file. Now, I have these link errors in my project:

g++ -o Chapter10(OpenCLTest).exe src\Chapter10(OpenCLTest).o -lopengl32 -lglew -lglut32 -lglu32 -lopencl
src\Chapter10(OpenCLTest).o:Chapter10(OpenCLTest).cpp:(.text+0x167): undefined reference to `_imp____glewBindBuffer'

It is good to solve this problem but by the way I want to ask are there any other opengl implementaions of gl extentions?

Answer 1

I'm afraid you can't use glew.lib with g++ (because .lib is a proprietary Microsoft format). These errors you get are missing function entry points, meaning that you didn't compile GLEW correctly (the required functions are not exported in your .so - need to know more details in order to be able to solve this issue).

As for the other part of the question, you can try GLEH. It is still in the development phase and may need some tweaking to work for you, but we've been using it quite successfuly in linux so it shouldn't be too bad.

Answer 2

(I know this is a bit late, but I figured it might solve someone else's problem, so) I had a very similar problem compiling a program that linked to GLEW dynamically. It turns out that I had overlooked the libglew32.dll.a file - that also needed to be present (in addition to libglew32.a and glew32.dll that I had previously copied to my project folder.)
