I made this change in Rawhide, so let's see how it goes ...

I don't believe that commit made a difference. Prior to that commit,
libvirt would always add Werror if biulding from git, even if meson
had already added Werror, causing a warning from meson.

Now we only add Werror if building from git and meson has not already
added Werror itself.

Normally -Dwerror=false would be sufficient for building from the
tarball, but in the RPM we're using git to manage patches, so we
need both options:

   -Dwerror=false -Dgit_werror=disabled

Turning off -Werror

2021-07-28 Thread Richard W.M. Jones


  commit 3c3c55be66e230ef09ad927eda038dc32f01a166
  Author: Daniel P. Berrangé 
  Date:   Thu Apr 8 11:50:30 2021 +0100

meson: don't probe for -Werror if --werror is enabled

Builds are failing in Fedora Rawhide at the moment because of a
warning being turned into an error.  Fedora's spec file has this which
is supposed to turn off -Werror, but it no longer works after the
above commit was added.

https://src.fedoraproject.org/rpms/libvirt/blob/rawhide/f/libvirt.spec#_189

I'm trying to understand how you're supposed to turn off -Werror.
According to meson documentation omitting --werror should work.
According to some different docs, use --werror=false.  Neither are
working for me.

I'm actually wondering if the commit above is wrong.

Rich.
