When req_version is None (e.g. pcap-config case) it gets printed in the
logs.
Take this opportunity to reformat the message to look more like
ExternalProgram messages.
Not need to catch exceptions in dependency_fallback(), it's already
handled in do_subproject(). This ensure subproject errors are handled
the same way when doing dependency() fallback and when doing
subproject().
Otherwise Python gets all confused and it makes testing difficult.
Also minimally emulate the behaviour of the normal object to make the rest
of the code happy.
If a configure_file has an install_dir set, the supported install
argument is ignored, while this should have actually higher priority
than the install_dir itself.
Also check that correct types are used for `install` and `install_dir`.
Add test to verify this.
Fixes#3983
On OpenBSD, the main PowerPC machine is known as macppc, while the processor
family is powerpc:
$ uname -{m,p}
macppc powerpc
$ echo 'import platform; print (platform.machine())' | python3
macppc
$ echo 'import platform; print (platform.processor())' | python3
powerpc
This allows for e.g. GLib configure to properly detect that cpu:
Build machine cpu family: ppc
Build machine cpu: macppc
While it failed before with: WARNING: Unknown CPU family 'macppc' <snip>
Since trying to cross compile for Windows from Linux (WSL) and having
paths like this:
'-L/mnt/c/Program Files (x86)/Microsoft Visual Studio/2017/\
Community/VC/Tools/MSVC/14.15.26726/lib/x64'
I found that the spaces and brackets in the paths weren't properly
escaped by the Ninja backend.
This adds a hidden option to dump the current otherwise hidden peristant
state in coredata.dat.
This interface is unstable as meson has no compatibility promises about
coredata.dat.
When python sees an invalid character in a filename for the current locale,
instead of clobbering it, it saves is as an invalid codepoint called a
surrogate. We need to explicitly instruct the encoder to write those out
as-is. In the JSON file, we replace them instead to produce valid json.
