SDL_Main or WinMain@16 error

[Michael Sgier]

Hi
While trying to compile the follwoing example with devC++
I get errors:

D:\SDL-1.2.7MingW\lib\libSDLmain.a(SDL_win32_main.o.b)
(.text+0x34b)
[Warning] In function `console_main':
[Linker error] undefined reference to `SDL_SetModuleHandle'
[Linker error] undefined reference to `SDL_main'
If I delete the SDL linker I get undefined reference to
WinMain@16
Thanks for help. Regards
Michael
PS: The links to sdl etc. should be fine tough.

Try including windows.h before any other headers and replace "int main()"
with "int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR
lpCmdLine, uint nCmdShow )"
