SDL2 will not bind correctly

Question

I am using Code :: Blocks, which is my code:

#include "SDL2/SDL.h" int main(int argc, char* args[]) { SDL_Init( SDL_INIT_EVERYTHING ); SDL_Quit(); return 0; } 

I build as:

 mingw32-g++.exe -o C:\..\main.exe C:\..\main.o -lmingw32 -lSDL2main -lSDL2 

And having received this:

 undefined reference to "SDL_Init" undefined reference to "SDL_Quit" 

I am sure that the linker will find the cause of the libs if I change them to something random, which it complains “cannot find anything”.

Answer 1

A bit late, but I just stumbled upon a similar problem on Linux.

This leads to linker errors:

 g++ $(pkg-config --cflags --libs sdl2) sdl2test.cpp sdl2test.cpp:(.text+0x11): undefined reference to `SDL_Init' sdl2test.cpp:(.text+0x20): undefined reference to `SDL_GetError' sdl2test.cpp:(.text+0x34): undefined reference to `SDL_Quit' 

It works:

 g++ sdl2test.cpp $(pkg-config --cflags --libs sdl2) 

Answer 2

even if this is a Linux problem, I got to this entry via google.

Mayb this can help someone else: I had the same problem with 32-bit Windows XP code blocks: Mingw + SDL2 and I fixed it after I copied the correct SDLFolders (include, lib ...) to the mingw folder . The reason I ended up in this pythall is because the name of the SDL-Rootfolder from the DEV-Pack is a bit confusing. You have the "x86_64-w64-mingw32" -Folder, which is for the 64-bit compiler and the "i686-w64-mingw32", which is for the 32-bit compiler (as is still the case). I messed it up because of the "x86 ..." naming, still don't know why they write it that way.

After overwriting the correct files, it works great for me.

Are you sure you have your libraries in your way?

Try adding -LC:/whatever/ with a folder that actually contains you libSDL2.a and other *.a to your compiler arguments.
