On Windows, how to use classes in C++ DLL library from Julia?

[barche]

CxxWrap supports using Visual Studio, and in fact does so by default on Windows for now, see:

GitHub - JuliaInterop/CxxWrap.jl: Package to make C++ libraries available in...

This in fact automates what @tkelman suggests. Also, there are caveats when not using the same compiler as Julia even when going through ccall, discussed here for instance:

Windows C++ binary compatibility: MinGW vs MSVC

Creating a new topic to continue the discussion about binary and compiler compatibility started here in the context of QML.jl. All of this is in the context of CxxWrap.jl, where C++ code is made available in Julia by building a small C++ wrapper library that is accessed from Julia using ccall. CxxWrap itself contains a C++ library, and so does any package built using it. Naturally, all of these have to be compiled with the same compiler for any binaries to be compatible with each other.
