Re: [libvirt-users] Compiling Libvirt on Windows for Hyper V support

[reza shahriari]

Hi,

I have hit a new issue with `./configure` when specifying the `—with-hyper` 
parameter.

Configure runs successfully when no parameters are given but when trying to 
build with hyper-v I run into this issue. I was wondering if anyone knows how 
to install this dependency on msys2.

Thanks,

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

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

The log shows

configure:8796: checking for pthread.h
configure:8796: gcc -c -g -O2  conftest.c >&5
conftest.c:82:10: fatal error: pthread.h: No such file or directory
 #include 
  ^~~
compilation terminated.


so it is not finding the winpthreads package you installed.

You might be ablke to set the  "CFLAGS" env variable to
"-I/path/to/winpthreads/include" to get it to work. Might
need LDFLAGS="-L/path/to/winpthreads/lib" too.

Daniel

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

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/

Unfortunately that page is somewhat stale.

These days you should not need to pass any args to configure - we should
automagicaly disable everything that doesn't work on Windows.

That said, officially the *only* way we support Windows right now is
via the mingw64 cross-compiler toolchain running on a Linux host, as
that is what our CI systems test for each release.

msys may or may not work - we dont have any CI systems or developers
actively testing that anymore.

So what arguments does msys2 pass to the configure script?

[libvirt-users] Compiling Libvirt on Windows for Hyper V support

[reza shahriari]

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,
