Hi, I just tried creating an x86 MSVC import lib for a libzmq.dll generated by MINGW32 on 32-bit Windows. I did get it to work. I imagine cross-compiled, 64-bit versions and libczmq.dll would work too.
There's no C++ name mangling issue since libzmq exports a C interface. The errors you encountered when compiling czmq with MSVC is probably due to the C99 style used in czmq. Follow instructions on the web to create a .def file: nm libzmq.dll | findstr /C:" T _z" > libzmq.def then edit the .def file so that it looks like this: EXPORTS zmq_bind zmq_close ... How does your .def file look like? Generate the .lib file: lib.exe /machine:x86 /def:libzmq.def Tested it out with a simple zeromq program compiled with MSVC.
