Yeah, I've use dlls made in gcc with dmd. You need to run implib
over the dll to get a .lib and then it works pretty easily.

implib /s mydll.lib mydll.dll


implib can be found in the basic utilities package at digital
mars.

Yes, it is possible.

Long ago i have dealt with this almost on a daily basis (we used Borland C++ Builder on Windows in the former company I worked for).

The easiest method is to use DEF files to create the import library. If you do not have it, you can use some tool that will analyse the DLL, make the DEF file for you, and then you modify it to your needs, and then create the import library for your target toolchain.

This article explains everything you need to know: http://wyw.dcweb.cn/stdcall.htm

Yes, this works in most cases, but when it does not, then you have to use DEF files and modify/add symbols. It is not complicated, just time-consuming...

Thanks, I'll give it a try.
