Right now sub-sub projects are not correctly registered, because we
don't have a way to pass up past the first level of subproject. This
patch changes that by making the build_Def_files as defined in the
Interpreter initializer accurate for translated dependencies, ie, cmake
dependencies won't define a dependency on a non-existent meson.build.
This means that it can always add the subi.build_def_files because they
are always accurate.
Subprojects that use the CMake PCH feature will cause
compilation/linker errors. The CMake PCH support
should thus be disabled until this can be properly
translated to meson.

Instead of trying to cover everything internally
When glib is a subproject we should use glib-compile-resources it
overrides using find_program() in the case it is not installed on the
build machine. With old glib version we have to run
glib-compile-resources at configure time to generate the list of
dependencies, but not when glib is recent enough.
wraps from subprojects are now merged into the list of wraps from main
project, so they can be used to download dependencies of dependencies
instead of having to promote wraps manually. If multiple projects
provides the same wrap file, the first one to be configured wins.
This also fix usage of sub-subproject that don't have wrap files. We can
now configure B when its source tree is at
`subprojects/A/subprojects/B/`. This has the implication that we cannot
assume that subproject "foo" is at `self.subproject_dir / 'foo'` any
more.
Sometimes, distros want to configure a project so that it does not
use any bundled library. In this case, meson.build might want
to do something like this, where slirp is a combo option
with values auto/system/internal:
slirp = dependency('', required: false)
if get_option('slirp') != 'internal'
slirp = dependency('slirp',
required: get_option('slirp') == 'system')
endif
if not slirp.found()
slirp = subproject('libslirp', ...) .variable('...')
endif
and we cannot use "fallback" because the "system" value should never
look for a subproject.
This worked until 0.54.x, but in 0.55.x this breaks because of the
automatic subproject search. Note that the desired effect here is
backwards compared to the policy of doing an automatic search on
"required: true"; we only want to do the search if "required" is false!
It would be possible to look for the dependency with `required: false`
and issue the error manually, but it's ugly and it may produce an error
message that looks "different" from Meson's.
Instead, with this change it is possible to achieve this effect in an
even simpler way:
slirp = dependency('slirp',
required: get_option('slirp') != 'auto',
allow_fallback: get_option('slirp') == 'system' ? false : ['slirp', 'libslirp_dep'])
The patch also adds support for "allow_fallback: true", which is
simple and enables automatic fallback to a wrap even for non-required
dependencies.
Currently if you change the `choices` field in the meson_options.txt
file, no update will be done until `meson setup --wipe` is called. Now
if the choices change then the options will be properly merged.
If the currently select value is still valid it is guaranteed to be
kept, if it is now invalid the new default value will be used and a
warning will be printed.
Fixes#7386
`pathlib.Path.glob()` also returns directories that match source
filenames (i.e. a directory named `test.h/`), but `clang-format` and
`clang-tidy` fail when handed a directory. We manually skip calling
`clang-format` and `clang-tidy` on those directories.
This is required to make the various keys in the [user options] section
work the same as they do in the meson_options.txt file, where we don't
have any rules about case sensitivity.
There is some risk here. Someone may be relying on this lower by default
behavior, and this could break their machine files.
Fixes#7731
There are two cases that won't work (these are taken from fortran/9
cpp), using gfortran with a non-gcc compiler on windows, or using
gfortran with apple clang. The latter is due to default search paths,
which we can fix, but is out of scope for this MR.
This is a test for https://github.com/mesonbuild/meson/pull/7021, to
verify that `link.exe` uses the correct architecture when targeting
ARM64. Can be extended to other cross targets later.
Split out tests (and parts of tests) which require a native compiler
from the 'common' suite to a new suite called 'native', so we can
selectively avoid running those tests when only a cross-compiler is
available.
Also move test '211 cmake module' to 'cmake' suite, since it appears
that the way we use cmake requires a native compiler.
If the meson.build doesn't use a native compiler, the native compiler
options (e.g. 'c_args') shouldn't be present in the output of 'meson
introspect --buildoptions'.
Something like {a: foo} currently stymies the IntrospectionInterpreter and
breaks introspection of the source directory. The fix is just to walk the keys
and return a dummy dictionary.

Add the ids of any target that needs to be rebuilt before running the
tests as computed by the backend, to the introspection data for tests and benchmarks.
This also includes anything that appears on the test's command line.
Without this information, IDEs must update the entire build before running
any test. They can now instead selectively build the test executable
itself and anything that is needed to run it.

when that statement gets evaluated, the interpreter remembers the
version target and if it was part of the evaluation of a `if` condition
then the target meson version is temporally overriden within that
if-block.

This removes the check for "mingw" for platform.system(). The only case I know
where "mingw" is return is if using a msys Python under a msys2 mingw environment.
This combination is not really supported by meson and will result in weird errors,
so remove the check.
The second change is checking sys.platform for cygwin instead of platform.system().
The former is document to return "cygwin", while the latter is not and just
returns uname().
While under Cygwin it uname() always starts with "cygwin" it's not hardcoded in MSYS2
and starts with the environment name. Using sys.platform is safer here.
Fixes#7552
This is useful for automatically generated docs (doxygen, hotdoc)
with a lot of generated files that may differ with different
versions of the generator.
