Re: [Mingw-users] [mingw - StupidTechiQuestions] Cannot link SDL+OpenGL example with MinGW

[Brian K. <bk...@em...>]

Command line order matters for mingw.  Try linking like this:

gcc example.o -o example -lSDLmain -lSDL -lmingw32 -lopengl32 -lglu32


Generally if a library depends on another then it should come earlier on the 
command line (eg. SDL depends on opengl in this example so place the SDL lib
before the opengl lib).
