It won't. The API exported by their DLL isn't even object. It looks like pure C calls, there are no classes at all. i have no idea why they didn't export it "extern C" at the first place.

Okay. i have asked the library vendors if they would do that (i won't do it myself, because their API might be subject to changes, and i'm not going to do that each time they release). As they are already developping on Windows with MSVC, it should be a no-brainer for them.

Thanks for the tip JonY :)
