There is no common ABI among C++ compilers. Thus, the libraries and headers of one can't be used as input to the compiler of another, even on the same platform. This only works for C code. So you have to either build the proprietary libs with Cygwin's C++ compiler or write your own "shim" library that wraps the necessary calls and objects in a C API, compile that with VS, and link your program against the APIs in your library.@Larry: Would this work? I think MSVC produces obj and lib files in COFF; can Cygwin's toolchain understand that?Being as this code is proprietary I doubt that Perforce will release it to me to compile but I will point them at this thread...'Maybe you can convince them to build a Cygwin version (not very likely).
I am in contact with Perforce about this. They think it's a wonderful idea and they fully want me to let them know when I've managed to accomplish this! ;-)
Needless to say, Cygwin, it's Perl and having a P4Perl available for it is not necessarily in Perforce's business model. Most people just use ActiveState. That said, with 5.18 I hear the backend moves to gcc and they need to address that issue. Once addressed having a Cygwin version may be easier for them to produce.
I, unfortunately, do not have a lot of time to dedicate to this as my client wants me to work on others things. Using Cygwin's Perl is a convenience for me but not a necessity, though I would love to have this working.
