Hi, D-people!

Is there any good example how to create D program for Windows using Ares library? How to compile/link them?

This is a good start:

http://www.digitalmars.com/d/windows.html

Replace "std.c.windows" with "sys.c.windows" and the example almost compiles. DMD still complains about an undefined symbol, __Dmain, but I think this may be a compiler issue. However, I added this to the sample:

int main() {}

and then it compiled and ran fine. Now that I've tried it, I don't really like how this process works, so I'll probably add a module to Ares to simplify things. It will be in sys.windows. Note that this means sys.c.windows will change to sys.windows.c and sys.c.linux will change to sys.linux.c, which seems to make more sense anyway.

Copied from digitalmars.D.learn:

I was promped to try creating a Windows application in D recently and was struck
by how complicated winsamp made it seem--no user should ever have to copy
portions of proprietary runtime code (dmain2) to make her D app work. This is
an alternate method I cooked up that works equally well and show be a bit more
portable:
Code:
import sys.windows.c.windows;

/*
 * Pass on all the real work to the standard main function.
 */
extern (C) int main( int argc, char **argv );
 
extern (Windows) int WinMain( HINSTANCE hInstance,
                              HINSTANCE hPrevInstance,
                              LPSTR     lpCmdLine,
                              int       nCmdShow )
{
    return main( 1, &lpCmdLine );
}
 
/*
 * Define your D main function as usual.  This will be called through
 * the extern(C) main function called above.  That's it!
 */
void main()
{

}

A working sample using this method (based on samples.d.winsamp bundled with DMD)
is available here:
