libvirt users - Aug 2019 - Re: Compiling Libvirt on Windows for Hyper V support

Hi,

I tried that out, I got a new error about pthreads in my config.log.

Could you take another look.

Thanks again,

Reza

It finds the header file now which is good, but it still fails to
find the libpthread.dll file, which is what LDFLAGS should have
addressed

configure:15417: checking for pthread_kill in -lpthread
configure:15442: gcc -o conftest.exe
-I/c/msys64/mingw64/x86_64-w64-mingw32/include/ 
-L/c/msys64/mingw64/x86_64-w64-mingw32/lib/:/c/msys64/mingw64/bin/ conftest.c
-lpthread   >&5
c:/mingw/bin/../lib/gcc/mingw32/8.2.0/../../../../mingw32/bin/ld.exe: cannot
find -lpthread
| char pthread_kill ();

Thanks so much. I got it to go past pthreads. Now I am working on other
dependencies
