Correct, using that option you can disable libvirtd which should reduce<br>
some dependencies but there is no option to disable virsh. We can<br>
possibly introduce an option to disable libvirt clients but that would<br>
save you only readline as a dependency which you can disable by using<br>
-Dreadline=disabled .<br>
<br>
If you want to do a minimal build of libvirt you can run meson with<br>
--auto-features=disabled which will disable most of the features and you<br>
can explicitly enable only the things that you want to use (this is what<br>
most distributions are doing when building packages). I just noticed<br>
that there are some build options where this doesn't work so I'll post<br>
patches to fix them.<br>
<br>
The last part I have to ask what do you mean by "without dynamic lib<br>
dependencies"? If you mean that libvirt.so should be statically linked<br>
that is not currently possible. We would have to add option to make it<br>
possible and update all dependency() and find_library() calls in all<br>
meson.build files to look only for static libraries.<br>
<br>
In addition I think we should add build options which would allow users<br>
to disable tests, documentation, examples and other bits that end-users<br>
don't have to use.<br>
