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?:
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
