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

Hi, 

I am trying to compile Libvirt from the source code on windows using msys2 but
keep hitting issues while running `./configure`.

Does anyone have any experience compiling Libvirt on a windows machine ?
Specifically I am trying to enable hyper-v domain on Libvirt.

Thanks,

Reza Shahriari

So what arguments does msys2 pass to the configure script?

Erik

I am passing in:

./configure \
  --without-sasl \
  --without-polkit \
  --without-python \
  --without-libxl \
  --without-qemu \
  --without-lxc \
  --without-openvz \
  --without-libvirtd

As the error message says, you need to have a pthreads impl to
build libvirt. This is not a standard part of Windows, but is
provided by the mingw64 cross compiler toolchain. I'm unclear
if its possible to get this into msys or not/

The pthreads library is a mandatory part of libvirt, so we can't
skip that.

Can you provide your "config.log" file - if it is larger than
200 KB, please compress it, or upload it somewhere

Hi,

I have attached my compressed config file.

Thanks,
