Unresolved external symbol for every glew function I use

I wanted to create new OpenGl/GLEW/GLFW Visual Studio project in 64 bit. So I downloaded glew binaries and glfw binaries. My project settings are as followed:

Additional Libraries:

  • glew-2.1.0\lib\Release\x64
  • glfw-3.3.bin.WIN64\lib-vc2019

Additional Dependencies:

  • glew32s.lib (I dont get why its named glew32 and its in x64 folder)
  • opengl32.lib
  • glfw3.lib

With such setting for every glew function like glGenBuffers or glUseProgram or anything I get LNK2001 unresolved external symbol error. Any clue where I did a mistake?

(And since I am a new to all of these can someone explain why do I have to link opengl32.lib on 64 bit app and why there is no opengl64.lib and so on?)

When you want to link the static glew library on windows, then you've to define the GLEW_STATIC preprocessor definition when you compile your application.
See Building Your Project with GLEW
and GLEW - why should I define GLEW_STATIC?.

If you use gnu (g++), then just add -D GLEW_STATIC to the build command.
In Visual Studio add GLEW_STATIC to the Project properties -> C/C++ -> Preprocessor -> Preprocessor Definitions

Well it seems to work when I link it dynamicly (glew32.lib instead of glew32s.lib). Still no clue why static linking didnt work out.
