Fetching cflags and libs can also fail if, for instance, the pkg-config
file for a dependency needed by this package isn't found. Without this,
we will print "Found: YES" and then "Found: NO".
Without this, macOS users can't figure out why a particular dependency
wasn't found because the pkg-config error message gets masked by the
fresh and useless DependencyException.
Don't need to define __init__ and manually call the parent init. Doing
so messes up the error message you get by doing str(exception) because
it includes the current class name in it repeatedly.
We were storing the pkg-config path on the class as a static variable --
PkgConfigDependency.pkgbin. When we regenerate via Ninja, the found-deps
are all cached in a pickled coredata, so if you have a statement that
does dep.get_pkgconfig_variable(), it will raise the following exception
because the static class variables are per-meson-invocation.
To fix this, we store the pkg-config binary as both a class variable and
an instance variable.

ninja: error: rebuilding 'build.ninja': subcommand failed
In several places in the gnome module, we are getting an array from this
and directly appending to it which changes the original command array
ever since we started caching the find_program results.
We urgently need to move to immutable types for all object properties.
Reported by Alexandor Larsson on IRC.
a) Don't search for pkg-config if we're only cross-compiling
b) Don't unconditionally error out while cross-compiling if the
specified pkg-config is not found and the dependency is optional
c) Use the pkg-config binary that was found in check_pkgconfig for the
actual testing
d) Use shutil.which on the found pkg-config only if it finds it.
Sometimes shutil.which fails to find it, for instance on Windows
with absolute paths.
When you pass an absolute path to shutil.which, it will not implicitly
append any extensions. This is problematic on Windows, so we need to
account for that.
This fixes detection of Qt tools on Windows which are searched with the
full path to the Qt bindir.
If it isn't, the --target-glib check in generate_vala_compile will
iterate over the version_reqs as a string and fail to add the
--target-glib argument.
Instead of adding it everywhere manually, create a wrapper called
mesonlib.Popen_safe and use that everywhere that we call an executable
and extract its output.
This will also allow us to tweak it to do more/different things if
needed for some locales and/or systems.
Closes#1079
On Windows, we can build with both 32-bit and 64-bit compilers, but the
Python is either 32-bit or 64-bit. Check the architecture of the found
Python libraries and don't use them if they don't match our
build_machine.
Also skip the tests if the Python 3 dependency is not found.
Sometimes we want to restrict the acceptable versions to a list of
versions, or a smallest-version + largest-version, or both. For
instance, GStreamer's opencv plugin is only compatible with
3.1.0 >= opencv >= 2.3.0
qmake for both Qt4 and Qt5 detection was assuming that it was only used
on Windows, which is incorrect. It can also be used on Linux for
cross-compilation or in general when pkg-config is not available.
It was also not failing properly for both Qt5 and Qt4 when no libraries
were found, and was assuming that the .dll was always available.
Qt4 detection with qmake was also completely broken.
Also prevents unwanted injection of partially-found qt dependencies in
targets by unsetting self.cargs and self.largs
Move CCompiler.compile to Compiler.compile so that ValaCompiler can use
it. Also rewrite ValaCompiler.sanity_check to use it since it does
a simple compile check.
At the same time, it enhances ExternalLibrary to support arguments for
languages other than C-like.
Includes a test for this that links against zlib through Vala.
Closes#983
* Simpler picking of pkg-config vs qmake detection
* qmake-based detection now allows specifying qmake via cross-info
* bindir is now stored from qmake/pkg-config detection and can be used
to detect qt tools such as moc, uic, rcc with self.compilers_detect()
* Qt4 dependencies got some love; now they share the implementation with
Qt5 since the two are very similar; basically identical
* Don't ask about Qt3
And remove the InternalDependencyHolder class.
In some cases we need to know the type of dependency we are
dealing with. For example in GStreamer if the dependency
is not an internal one, then we need to get some env var
from pkg-config to know where to find some plugins necessary
to run some tests.
Reduces duplicated code, and also use universal_newlines=True which
avoids having to decode the bytes output to string.
We mostly need this so we can pass the *current* process environment to
pkg-config which might've changed since the module was imported. Without
this, subprocess.Popen invokes pkg-config with a stale environment (used
in the unittest added later)
Fixes https://github.com/mesonbuild/meson/issues/526
Also removes useless and incorrect mesonlib.is_32bit() function. We
cannot trust that the architecture that Python is built for is the same
as the one we're targetting.
Because of how files and executables work on Windows, scripts that use
an interpreter must have an extension, and that extension must be
associated with an interpreter. The full list of executable extensions
is available in the PATHEXT environment variable.
However, UNIX-like OSes use an executable bit and read the shebang to
figure out what interpreter to use, and the scripts don't need to have
extensions. We can now detect these scripts using find_program by
manually searching in PATH and reading the shebang.
This gives a clearer output when the dependency is not required or has a
fallback subproject otherwise the user is left wondering why the optional
dependency wasn't used or why the fallback subproject is being used.
Just exit immediately when there's no pkg-config file found instead of putting
everything else in a huge 'else:'. Much clearer and avoids one level of
indentation.
No code changes accompany this.
