I am trying to link SDL, GL and GLew with mingw. This is my compile command:



g++ -mwindows main.cpp -o arcanacaelestia.exe

-IC:\Users\Light\Programming\SDL-1.2.15\include

-IC:\Users\Light\Programming\glew-1.7.0\include

-LC:\Users\Light\Programming\SDL-1.2.15\lib\x86

-LC:\Users\Light\Programming\glew-1.7.0\lib

-lmingw32 -lglew32 -lSDL -lSDLmain -lopengl32

and I am having problems with SDLmain. These are the errors I get:

I've tried with and without the -mwindows option.

SDL and SDLmain are in the path

Completely wild guess here, but have you tried wrapping the #includes for SDL in an extern "C" { ... }? It may have been compiled with C linkage.

I had a ton of different compilers and versions of the same libraries. I came to the conclusion that I'll just get rid of them all and redownload MinGW and the appropriate libraries that I need. Turns out I was linking to Visual Studio version of the SDL library with mingw... Also, it is important to put -lSDLmain before -lSDL or else I get undefined references as well. Anyways it seems to work now with the following command:



g++ main.cpp -o arcanacaelestia.exe

-IC:\Users\Light\Programming\SDL-1.2.15\include

-IC:\Users\Light\Programming\glew-1.7.0\include\GL

-LC:\Users\Light\Programming\SDL-1.2.15\lib

-LC:\Users\Light\Programming\glew-1.7.0\lib

-lmingw32 -lglew32 -lSDLmain -lSDL -lopengl32

It turns out I have a runtime error which I think is related to all of this because I was able to get the same code to run in MSVC. This is what I am getting:

Sounds to me like some reference disappeared. Or a pointer is accessing memory that doesn't exist.
