I have missing opengl32 library (more details: mingw32 w64 missing OpenGL32 lib). I have several questions related to this library:

  1. Why I need opengl32 static library ( I have .dll)?
  2. Why video card vendors does not provide this library?
  3. Who should provide it?
  4. Is there a source code of opengl32 library?
  5. Why I need GLEW or other GL library implementations (to use all features of OpenGL) if there is opengl32? Why opengl32 cannot have all required GL implementation?

    1. It’s not a static library, it’s the library to dynamically link to the DLL.
    2. Because it’s a part of the OS, more or less. The symbols exported from OpenGL32.dll tend to be standard (a particular set of gl... functions) and Microsoft-specific (wgl ones at least). The publicly-known ones don’t vary between vendors.
    3. Microsoft does provide it, with their compilers. Any other compiler vendor should as well, since libs can be somewhat compiler-specific.
    4. Mesa is an open-source OpenGL implementation, so the closest you’ll get.
    5. You don’t, you can get the strings and function pointers manually, it’s just extremely tedious. GLEW et al do most of the feature-checks and initialization for you. They don’t do anything you can do directly with OpenGL32.dll, but they do make life a lot easier.
