In version 3.6.0, clang added -Wignored-optimization-argument. Without
setting this flag to -Werror, "ignored optimization arguments" such as
(for example) -fpeel-loops, are accepted but warned about, leading to
noisy builds if meson thinks the flag is supported.

PR #1955 added implib to known_exe_kwargs, but since PR #2001 it needs to be
in exe_kwargs as well, to avoid 'WARNING: Passed invalid keyword argument
"implib"' when it is used.
99% of all mkenums uses in C libraries use the same basic template,
so add a mkenums_simple() function that takes care of everything for
us based on that template.
Features:
- optional function declaration decorator such as GLIB_AVAILABLE
- optional extra header prefix (e.g. for include needed for decorator)
- optional extra body prefix (e.g. for additional includes)
- optional function name prefix (e.g. to add leading underscores)
Fixes issue #1384
CCache requires this flag when building with precompiled headers.
Without it, the preprocessor fails and CCache fallbacks to running the
real compiler.
Users still need to set 'sloppiness' to 'pch_defines,time_macros' in
their ccache.conf file for CCache to cache builds that use precompiled
headers. See the CCache manual for more info:
https://ccache.samba.org/manual.html#_precompiled_headers
gnome.compile_resources() was not parsing custom target sources
properly. It was using the custom target name as the output of the
custom target instead of looking at the list of outputs.
Also modify the GNOME framework test to expose this.
Libpcap has its own pcap-config tool rather than using pkg-config. Add
support for pcap-config, based on the existing implementation of
sdl2-config that is there already.
As stderr may contain information the user can use to solve the problem with
the gcc installation, it should not be ignore but added to the error message.
The valac binary was hard coded in meson. We now check if VALAC is
defined in the environment, and if it is, use its value as the vala
compiler, if not, we proceed with the hard coded binary name.
We prefer pkg-config files, though only OpenMPI supplies them.
Otherwise, check environment variables and search for wrappers and ask
them for what to do.
Currently if a target uses link_whole, and one of those archives is a
C++, but the files for the target are C linking will fail when the C
linker attempts to link the C++ files. This patches add
link_whole_targets to the list of languages in the target so the correct
linker will be selected.
We prefer to use the --extra-library parameter for passing -l arguments
to g-ir-scanner, however we need to be careful to only replace the first
'-l' occurrence to not translate
'-lfoo-lib'
to
'--extra-library=foo--extra-library=ib'
Introduce a DirMaker class that disassembles the path up to '/' and stores all
directories in a list. That list is in creation order and pre-existing
directories are ignored, i.e. creating the two paths
'/usr/share/foo/bar/baz' and '/usr/share/foo/bar/boo' is stored as
[ '/usr/share/foo',
'/usr/share/foo/bar',
'/usr/share/foo/bar/baz',
'/usr/share/foo/bar/boo' ]
This is on the assumption that /usr/share already existed.
After all files have been installed, the list of created directories is
appended in reverse order to the install log. The uninstall script then
triggers rmdir on all directories.
If a custom install script drops files into the directories, removing those
will fail. This matches the current expectation, see the existing warning
"Remember that files created by custom scripts have not been removed."
Unfortunately, this makes the behavior on uninstall inconsistent. Assuming a
non-existing prefix,
ninja install && ninja uninstall
removes all traces of the install.
However,
ninja install && ninja install && ninja uninstall
removes the files only, not the directories as they already existed.
This could be fixed by just unconditionally removing any (emtpy) directories
that we drop files into, at the risk of removing system directories if empty.
For example, one could imagine /etc/foo.conf.d/ to be removed in that case if
it is empty.
