If you have issues compiling the application, first make sure all your linker options are set correctly and that you properly included the right directories in your IDE (as explained in the previous chapter). In the "Select Directory" window, the "Folder" should be "lib-vc2019" or the latest. You might still get GL_INVALID_ENUM (depending on the version of GLEW you use), but at least GLEW ignores glGetString(GL_EXTENSIONS) and gets all function pointers. consider supporting our work with a contribution to wikiHow.
