Cross compile for Windows using x86_64-w64-mingw64 #632

Open JlnWntr opened 2 years ago

JlnWntr commented 2 years ago

I tried to CC="x86_64-w64-mingw32-gcc" ./configure --host=x86_64-w64-mingw64 on a Ubuntu subystem and make gave me

Am I doing this right? :)

No idea, since I have no experience with Windows based systems including cross compiling for it... Can't you compile it natively on Windows?

Give CMAKE a try... :)

Give CMAKE a try

I believe you have to know cmake in order to do that. (And that's an entirely different chore.) How do you tell cmake to use mingw or crosscompile for windows?

$ CC="x86_64-w64-mingw32-gcc" cmake ../usrsctp/ throws this error:

The C compiler

    "/usr/bin/x86_64-w64-mingw32-gcc"

  is not able to compile a simple test program.

Which is odd, since I've already compiled other libraries using mingw.

@tuexen : The possibility to crosscompile usrsctp is in my opinion really interesting combined with the idea that it is advertised to be portable. (Which it is.)

No idea. I'm always referring to @weinrank for any cmake related question...

I agree, but I have never done it...

Not touching CMake with a ten foot pole but I regularly built usrsctp for Windows as a Meson subproject via Dockcross in a CI environment, so it's definitely possible: https://github.com/rawrtc/ci-image/tree/cross/windows-x64
