Whilst working on the Reproducible Builds effort [0], I noticed that meson did
not generate reproducible .cmake files: they include the full path name.
This commit not only makes the build reproducible, but it also matches CMake's
own behaviour. Specifically, CMakePackageConfigHelpers.cmake does the
equivalent transformation using:
get_filename_component(inputFileName "${_inputFile}" NAME)
I originally filed this in Debian as bug #1000327 [1].

Contrary to most system method checks, zlib currently functions as a
whitelist of OSes. This isn't really needed however. The first special
case for OSes that provide zlib as part of the base OS is worth keeping.
However, the elif for windows is more than generic enough to allow any
other potential OSes to try. Just make it a simplie if/else instead.
Since these aren't warnings, per se, we don't note every single call
site that has one. And we raise mlog.notice in non-fatal mode to avoid
either:
- being too threatening
- making builds fail with --fatal-meson-warnings
Nevertheless, it is useful to give people a heads-up that there is an
upgrade opportunity, rather than waiting until they upgrade and then
causing projects to begin printing fatal warnings.
mlog can already print location info, and we use this often -- including
for custom feature warnings already. Make this work everywhere, so that
it is feasible to move such custom warnings to globally tracked
Features.
This is only relevant on certain versions of meson, so do not print it
when meson_version is too low.
The message itself is not precisely a deprecation warning, since
ostensibly it may be an unlikely coding mistake. It is probably an
attempt to implement `copy: true`, but it might not be, hence "warning"
instead of "deprecation". So although we could switch this to a
FeatureDeprecated, that is not being done at this time.
We went straight to the extra message, which when parsed as a subproject
string resulted in the Feature being entirely skipped because "project()
has not been parsed yet" as it could not find a subproject named that.
This tries to link the system provided python, which is deprecated and
will result in an ambiguous error like "your binary is not an allowed
client of .../Library/Frameworks/python.framework/python.tbd for
architecture x86_64".
Depending on whether hdf5 is compiled with parallel support, the
same config-tool program may be installed with a mysterious "p" in the
name. In this case, dependency lookup will totally fail, unless of
course you use the superior pkg-config interface in which case you get a
predictable name.
Work around this insanity by checking for both types of config-tool
name.
Fixes#9555
When input kwarg is missing in i18n.merge_file() it was crashing with a
backtrace because of kwargs['input'][0]. That code was useless anyway
because CustomTarget now uses first output as default name which is what
we need here.
While the horizontal line and the other pictograms in mtest have an ASCII-only
version, the spinner does not. This causes mtest to fail with a
UnicodeEncodeError exception on non-Unicode locales.

Virtualenvs do not have their Python DLLs etc in the `sys.prefix`
directory, but in the `sys.base_prefix` directory. This directory is
the same as `sys.prefix` if not in a virtualenv, so is safe for either
case:

If the LTO threads == 0 clang will default to the same argument we
manually pass, which meant we dropped support for admittedly ancient
versions of clang that didn't yet add that option.
Drop the extraneous argument, and add a specific error condition when
too old versions of clang are detected.
Fixes#9569
Without this patch, the name of the RunTarget is passed to the
install script; for the enclosed test, meson setup (incorrectly)
succeeds, but installation fails.
Fixes the following error in the testcase:

We currently enable this only for rcc (where this really really matters)
but it can often matter for moc as well, and is just generally more
correct.
Really, this should have been added in #7451 too, but I neglected it
since the module warned about inaccurate dependencies only for rcc...
All kwargs inherited from has_header need to be prefixed `header_` so we
cannot just do straight inheritance. And the part of the description
that highlighted the way kwargs are derived and evolved, went entirely
missing.
Fixes#9551
When installing with 'meson install --quiet' I'd get the following output:
This file does not have an rpath.
This file does not have a runpath.
(It turns out that of the couple hundred of binaries that are installed,
this message was generated for /usr/lib/systemd/boot/efi/linuxx64.elf.stub.)
There doesn't seem to be any good reason for this output by default. But those
functions can still be used for debugging. Under a debugger, returning the
string is just as useful as printing it, but more flexible. So let's suppress
printing of anything by default, but keep the extractor functions.
The code was somewhat inconsistent wrt. to when .decode() was done. But it
seems that we'll get can expect a decodable text string in all cases, so
just call .decode() everywhere, because it's nicer to print decoded strings.
This removes the `packages` keyword argument, which was added in
80d665e8de, but beyond not warning about
unknown arguments has never done anything, and has never been
documented. The only users I could find were in our own test suite. If
someone is using this we can add it back with a deprecation warning.
