c++ - Undefined reference to 'SDL_main'

Question

I've recently decided to try working with SDL with CodeBlocks 10.05. I started with the tutorial on http://www.sdltutorials.com/sdl-tutorial-basics and did my best to follow it. Unfortunately, I'm encountering:

............SDLSDL-1.2.15liblibSDLmain.a(SDL_win32_main.o):SDL_win32_main.c|| undefined reference to `SDL_main'|

when I try to compile it.

I've searched through many of the questions on this website and other tutorials (mainly the tutorial on LazyFoo and the CodeBlocks wiki) and can't seem to find a solution.

• C:SDLSDL-1.2.15include has been added in the Compiler tab (Search Directories)
• C:SDLSDL-1.2.15lib has been added in the Linker tab
• The libraries libmingw32.a, libSDLmain.a, libSDL.dll.a are linked in that order
  • libmingw32.a from the MinGWlib folder in the CodeBlocks installation directory
• SDL.dll is in both the System32 folder and in the project folder

When attempting to follow the tutorial on the CodeBlocks wiki, I was told that SDL.h could not be found in the given directory (when making a new SDL project).

CApp.cpp

#include "CApp.h"
#include "SDLSDL.h"

CApp::CApp(){
    Surf_Display=NULL;

    Running=true;
}

int CApp::OnExecute(){
    if (OnInit()==false){
        return -1;
}

SDL_Event Event;

while (Running){
    while (SDL_PollEvent(&Event)){
        OnEvent(&Event);
    }
    OnLoop();
    OnRender();
}

OnCleanup();
return 0;
}

int main(int argc, char* argv[]){
    CApp theApp;

    return theApp.OnExecute();
}

CApp.h

#ifndef CAPP_H_INCLUDED
#define CAPP_H_INCLUDED
#include "SDLSDL.h"

class CApp{
    private:
        bool Running;
        SDL_Surface* Surf_Display;

    public:
        CApp();
        int OnExecute();

    public:
        bool OnInit();
        void OnEvent(SDL_Event* Event);
        void OnLoop();
        void OnRender();
        void OnCleanup();
};



#endif // CAPP_H_INCLUDED

put these arguments to the main function. I had this problem too, and I fixed it few seconds ago.

int main(int argv, char** args) { }
