How can I make a stdcall function on Linux with DMD? extern(Windows) works, but it gives it DMC's Windows name mangling (e.g. foo@4) that is not compatible with Linux' stdcall C functions.

If this won't be changed in DMD's Linux version, I suppose I could settle with manually telling ld how to translate the names. Anyone know if this is possible or how?

I didn't know Linux even had stdcall C functions.

GCC has __attribute__((__stdcall__))

Specifically, I want to work with winelib, which is a Windows API implementation for Linux (and others); and like Windows, uses stdcall.

Also, there's a static assert in std.c.windows.windows preventing it from working with winelib; I had to comment that line out and it at least compiled, just wouldn't link due to the stdcall stuff.

If Linux's stdcall functions are for compatibility with Windows, why aren't they compatible with Windows name mangling?

I don't think that's its one and only purpose. Just what I want it for now. Besides, I don't think all Windows compilers mangle stdcall that way, and linux ones don't.

Hmm, DMD matches the way Microsoft's compiler mangles stdcall names.

The attached program might help:
1) use extern(Windows) in your sources
2) compile
3) dmd_wine_fixer <your_object_file>
4) link

__attribute__((__stdcall__)) does nothing in gcc on Linux. Windows and
Linux do not share the same ABI, so gcc doesn't care about that
attribute on non-Windows OS's as far as I know.

It's doing something here, on 32 bits. I tested it by marking a function definition as stdcall but not its prototype; it linked but did odd things before segfaulting. Matching both without stdcall or both with stdcall made it work as normal.

However, I did notice with 64 bits, gcc will ignore the stdcall attribute.
