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'
