Hi everyone, I'm new to here, and this is my first post, desperate for help.

I've downloaded and installed required SDL files, as explained in the wiki, http://gpwiki.org/index.php/SDL:Tutoria ... 2B.2B_.NET

When I include sdl.h under main, I get an error while debugging, which I totally do not understand. I have no idea what is wrong.

Code:

1>------ Build started: Project: RPG_GFX, Configuration: Debug Win32 ------
1>Linking...
1>MSVCRTD.lib(cinitexe.obj) : warning LNK4098: defaultlib 'msvcrt.lib' conflicts with use of other libs; use /NODEFAULTLIB:library
1>SDLmain.lib(SDL_win32_main.obj) : error LNK2019: unresolved external symbol _SDL_main referenced in function _main
1>C:\Users\Tarik\Desktop\My Custom Projects\RPG with GFX\RPG_GFX\Debug\RPG_GFX.exe : fatal error LNK1120: 1 unresolved externals
1>Build log was saved at "file://c:\Users\Tarik\Desktop\My Custom Projects\RPG with GFX\RPG_GFX\RPG_GFX\Debug\BuildLog.htm"
1>RPG_GFX - 2 error(s), 1 warning(s)
========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ==========

Again, I'm a starter to programming, and this is my first post here. Hopefully I'm posting at the right section, if not, I apologise. I'd be so glad if anyone could help me on this error, and in a rather simpler English as it's not my native langauge.

Thanks, and have a nice day.

Note: Using Visual Studio 2005, and the problem occurs on a Win32 Console Application.

This should be under the C++ section. I'll move it for you

The issue could be one of 2 things. Either you haven't linked to the SDLmain.lib file in your project or you haven't named your main function correctly for an SDL project. For SDL, main should be one of the following:

Code:

int main(int argc, char*argv[])

int main(int argc, char**argv)

sdl.h will perform a rename of this function to SDL_main (or similar) so that it can do some pre-setup of SDL before actually getting to your main function, but it means you are required to have the correct signature (otherwise it can't find your main function and you get unresolved symbols like the one you have encountered

)

I renamed main function as you suggested, and now it works like a dream.

Didn't expect such a useful reply in such short time. Thank you very much workmad3!
