Question

This is my situation:
1) I have checked with the the glewinfo tool of the GLEW library and found that my graphic driver support the glGenerateMipmapEXT function:

glGenerateMipmapEXT:                                         OK

2) I have get the GLEW code and rebuild it on VC++ 2010, I dont know whether files in the auto\core\ or auto\extensions\ folder affect my build or not 🙁

3) When building my source code which use the glGenerateMipmapEXT function, the VC++ give me an error

 error LNK2001: unresolved external symbol __imp____glewGenerateMipmapEXT

So, how do I use the glGenerateMipmapEXT function?

Answer 1

• init opengl window
• glewInit()

• create the texture and use glGenerateMimapEXT()

  if (GLEW_EXT_framebuffer_object)
  {
  // you have FBO and glGenerateMipmapExt !
  }

you should have GFX card that supports OpenGL 2.1 to be sure to have those extensions…
