Hi David,


Regarding your problems with generating your_filetm.c, you can try the 
following ...


    Select Project -> Settings...
    Select your_file.tm in the panel on the left.
    Select the Custom Build tab.

    In the Commands section make sure you have something like ...
    mprep your_file.tm -o your_filetm.c

    In the Outputs section make sure you have something like ...
    .\your_filetm.c


Hope this helps.

Below is the form of the main() function I always use -- I am not sure 
if this is the latest.

Lawrence

#if MACINTOSH_MATHLINK

int main( int argc, char* argv[])
{
    /* Due to a bug in some standard C libraries that have shipped with
     * MPW, zero is passed to MLMain below.  (If you build this program
     * as an MPW tool, you can change the zero to argc.)
     */
    argc = argc; /* suppress warning */
    return MLMain( 0, argv);
}

#elif WINDOWS_MATHLINK

#if __BORLANDC__

int PASCAL WinMain( HINSTANCE hinstCurrent, HINSTANCE hinstPrevious, 
LPSTR lpszCmdLine, int nCmdShow)
{
    char  buff[512];
    char FAR * buff_start = buff;
    char FAR * argv[32];
    char FAR * FAR * argv_end = argv + 32;

    if( !MLInitializeIcon( hinstCurrent, nCmdShow)) return 1;
    MLScanString( argv, &argv_end, &lpszCmdLine, &buff_start);
    return MLMain( argv_end - argv, argv);
}

#else

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

#endif
