Here's an useful tutorial about how to set up Simple Directmedia Layer library in Pelles C:

http://www.friedspace.com/cprogramming/sdlsetup.php

Today: 1.6.2011. I test SDL 1.2.14 on Pelles6.50 rel..candidate. It is still functional! This is is perfect cookbook how to setup. Step by step (or "microstep"). 1/Small appendix: be aware to switch ON Project/Option/Compiler [v] Enable Micr. extensions (It's not default).
2/Comments:
BTWay: does anybody know, how to use static linking with DLL? I need to distrib. my small funny game(s) like only one exe file. Manhy thanks.

Will this procedure continue to work with the revised new version 1.3?

I don't know if I'd want to be copying 3rd party files into the include and lib folders for Pelles C.... It would be a lot smarter to keep SDL in it's own folders and modify the Project->Project Options->Folders as needed for projects that include SDL.

That exactly what I do in this situation. Keep external things separate, the same goes for DirectX.

You never know what you break, if you include too many extensions by default.

I threw together a little hack for this using __stdcall calling convention it's essentially the same as the original SDL_win32_main.c with the calls to atexit() removed and the SDL exit routines placed before exit is called to close the program.

Code: [Select]
/*
    SDL_main.c, placed in the public domain by Sam Lantinga  4/13/98

    The WinMain function -- calls your program's main() function
*/
/********************************************************************************/
/*
Changed a few things to make this compile with Pelles C with the __stdcall
calling cnvention. Basically removed references to and placed all clean up
functions before exit is called.
