Meson build

Hi, Just a heads up on my experiences with the new build system. Arch Linux meson-0.55.1 Overall, it looks good, so well done! Just a couple of minor things I noted: 1. Arch uses a meson wrapper script (arch-meson) that sets:   --buildtype plain This seems to trigger a bug in meson that results in copious bogus compiler warnings: cc1: warning: ‘-Wformat-y2k’ ignored without ‘-Wformat’ [-Wformat-y2k] cc1: warning: ‘-Wformat-extra-args’ ignored without ‘-Wformat’ [-Wformat-extra-args] cc1: warning: ‘-Wformat-zero-length’ ignored without ‘-Wformat’ [-Wformat-zero-length] cc1: warning: ‘-Wformat-contains-nul’ ignored without ‘-Wformat’ [-Wformat-contains-nul] cc1: warning: ‘-Wformat-security’ ignored without ‘-Wformat’ [-Wformat-security] which of course breaks -Werror builds. I can easily work around it by setting `-D git_werror=disabled' or even better still: CFLAGS+=" -Wall" arch-meson... Maybe this github issue is related?: https://github.com/mesonbuild/meson/issues/7399 2. Arch currently builds libvirt with support for ZFS. Seeing as ZFS is not in the distro proper, a simple Autoconf tweak is used: ZFS=/usr/bin/zfs ZPOOL=/usr/bin/zpool \ ./configure ... This is surprisingly hard to emulate with meson, in fact it appears impossible, unless I resort to dodgy hacks with sed etc. Cheers
