Hi. I'm trying to use SDL v1.2.11 with one of my projects, but I keep
getting these weird errors.

This is my program:

----------

#include "SDL.h"

int main(int argv, char* argc[])
{
return 0;
}

----------

From that, I get all this:

----------

SDL_main(int,char * *)
:: === Build finished: 6 errors, 5 warnings ===

----------

For installing SDL, I downloaded the development libraries for Visual C
++ from the SDL web site. I put SDL.dll in both Borland's Bin
directory and in my project folder. I put all of the SDL header files
into Borland's Include directory. I called coff2omf on SDL.lib and
SDLmain.lib and put the new files into Borland's Lib director.

The only flag I set was -w (display all warnings). I also tried
replacing "main" with "SDL_main." Can anyone tell what's going on?

The error messages are clear. There is a problem with the header file.
When you use a header file that was created for a different compiler it is
possible that that file is done in a manner which is specific to the
compiler for which it was intended. The way one fixes that is to look at
the header file, determine what items generate the errors and alter them to
not generate errors.

One thing you could try to see if it reduces the number of errors is to
include stdio.h and stdlib.h prior to including stl.h

The errors are all from the compiler and not from the linker. Coff2omf
creates an import library for the linker to use so it is not an issue here.
