undefined reference to `WinMain@16'

Question

When I try to build a program using Eclipse CDT, I get the following:

/mingw/lib/libmingw32.a(main.o):main.c:(.text+0x106): undefined r

Answer 1

I was encountering this error while compiling my application with SDL. This was caused by SDL defining it's own main function in SDL_main.h. To prevent SDL define the main function an SDL_MAIN_HANDLED macro has to be defined before the SDL.h header is included.
