Using the std option, so now `rust_std=..` will work. I've chosen to use
"std" even though rust calls these "editions", as meson refers to
language versions as "standards", which makes meson feel more uniform,
and be less surprising.
Fixes: #5100
Apparently anchor links are case-sensitive and needs to be lowercase in hotdoc.
Prior to this change the anchor links were uppercase so the link did not refer to the anchor tag.
Likely that there are more occurrences around the docs than this, have not looked.
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.
You could always specify a list of tests to run by passing the names as
arguments to `meson test`. If there were multiple tests with that name (in the
same project or different subprojects), all of them would be run. Now you can:
1. Run all tests with the specified name from a specific subproject: `meson test subprojname:testname`
1. Run all tests defined in a specific subproject: `meson test subprojectname:`
Also forbid ':' in test names. We already forbid this elsewhere, so
should not be a big deal.
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.
Automatic fallback to subprojects is complicated and should be
pointed out outside the "fallback" keyword argument. It is also
surprising that fallback to a subproject will not happen if
override_dependency has already been used with the request
dependency. Document all this.
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
Instead of the default ones, this is especially important when cross
compiling or when using compilers that aren't compatible with the
default ones.
squash! dependencies/hdf5: Use the actual system compilers
Those function are common source of issue when used in a subproject because they
point to the parent project root which is rarely what is expected and is a
violation of subproject isolation.
* Add preliminary support for the CompCert C Compiler
The intention is to use this with the picolibc, so some GCC flags are
automatically filtered. Since CompCert uses GCC is for linking, those
GCC-linker flags which are used by picolibc, are automatically prefixed
with '-WUl', so that they're passed to GCC.

add CompCert to meson (does not fully work, yet)
* remove unused import and s/cls/self/
fixes the two obvious LGTM warnings
* CompCert: Do not ignore unsupported GCC flags
Some are safe to ignore, however, as per
https://github.com/mesonbuild/meson/pull/7674, they should not be
ignored by meson itself. Instead the meson.build should take care to
select only those which are actually supported by the compiler.
* remove unused variable
* Only add arguments once.
* Apply suggestions from code review

* Remove erroneous ' ' from '-o {}'.format()
As noticed by @dcbaker
* added release note snippet for compcert
* properly split parameters
As suggested by @dcbaker, these parameters should be properly split into multiple strings.

This means that, in the common case of a simple meson.build which
doesn't contain any 'native: true' targets, we won't require a native
compiler when cross-compiling, without needing any changes in the
meson.build.
Documentation of most methods mentions method arguments enclosed in
parentheses. Two methods are an exception and we fix them here to make
the manual more consistent.
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.

The -Doption=value style argument works for all builtin options,
and compiler options passed to meson. And some universal options,
have additional ways to be passed. However, base options (and compiler
options) do not have exactly the same ways of passing as universal
options.
This change adds a few pieces of information, which might get lost,
if the manual is not read serially.
[skip ci]
This is useful for automatically generated docs (doxygen, hotdoc)
with a lot of generated files that may differ with different
versions of the generator.
A common pattern in Qt5 applications is to embed translations in the
executable using the qresource system. In this case, the list of
translation files is already available in the .qrc file and there's no
good reason to duplicate this info in meson.build.
Let compile_translations optionally take a qrc input, in which case it
will go straight to generating the relevant translations and
rcc-generated .cpp, and directly return the thing users actually care
about -- the .cpp for linking.
There are a couple new users of Meson that might be worth mentioning.

- Exceptions raised during subproject setup were ignored.
- Allow c_stdlib in native file, was already half supported.
- Eliminate usage of subproject variable name by overriding
'<lang>_stdlib' dependency name.
This attempts to clarify the usage of strings and arrays, as well as
document the boolean type that has been exposed via the project and
built-in options
This is like the project options, but for meson builtin options.
The only real differences here have to do with the differences between
meson builtin options and project options. Some meson options can be set
on a per-machine basis (build.pkg_config_path vs pkg_config_path) others
can be set on a per-subproject basis, but should inherit the parent
setting.
This allows adding a `[project options]` section to a cross or native file
that contains the options defined for a project in it's meson_option.txt
file.
* Add boost_root support to properties files
This commit implements `boost_root`, `boost_includedir`, and
`boost_librarydir` variable support to native and cross properties
files. The search order is currently environment variables, then
these variables, and finally a platform-dependent search.
* Add preliminary boost_root / boost_includedir tests
Each test contains a fake "version.hpp", as that's how boost detection is
currently being done. We look for this file relative to the root directory,
which probably shouldn't be allowed (it previously was for BOOST_LIBRARYDIR
but not for BOOST_ROOT). It also cannot help with breakage detection in
libraries, however it looks like this wasn't getting tested beforehand.
I've given the two unique version numbers that shouldn't be present in any
stock version of boost (001 and 002).
* Add return type to detect_split_root
* Return empty list when nothing found in BOOST_ROOT, rather than None
* Update boost_root tests
* Create nativefile.ini based on location of run_project_tests.py
* Add fake libraries to ensure boost_librarydir is being used
* Require all search paths for boost to be absolute
* Redo boost search ordering
To better match things like pkg-config, we now look through native/cross files,
then environment variables, then system locations for boost installations.
Path detection does not fall back from one method to the next for properties or
environment variables--if boost_root, boost_librarydir, or boost_includedir is
specified, they must be sufficient to find boost. Likewise for BOOST_ROOT and
friends. pkg-config detection is still optional falling back to system-wide
detection, for Conan.
(Also, fix a typo in test 33's nativefile)
* Correct return type for detect_roots
* Correct boost dependency search order in documentation
* Print debug information for boost library finding, to resolve CI issues
* Handle native/cross file templates in a more consistent way
All tests can now create a `nativefile.ini.in` if they need to use some
parameter that the testing framework knows about but they can't.
* Pass str--rather than PosixPath--to os.path.exists, for Python35
* Look for boost minor versions, rather than boost patch versions in test cases
* Drop fake dylib versions of boost_regex
* Prefer get_env_var to use of os.environ
* Correct error reporting for relative BOOST_ROOT paths
* Bump version this appears in. Also, change "properties file" to "machine file" as that appears to be the more common language.
We have experimented with the module for about a year in a qemu
branch (https://wiki.qemu.org/Features/Meson), and we would like to
start moving the build system to meson. For that, keyval should have
the stability guarantees.

This header erroneously referred to the dynamic linker while the paragraph talks about
the "link editor." Change the title to account for the difference.
We don't need the legacy variable name system as for dependency()
fallbacks because meson.override_find_program() is largely used already,
so we can just rely on it.
The value for that key must be a coma separated list of dependecy names
provided by that subproject, when no variable name is needed because the
subproject uses override_dependency().
Machine files already supports `+` operator as an implementation detail,
since it's using eval(). Now make it an officially supported feature and
add a way to define constants that are used while evaluating an entry
value.
The documentation of gnome.generate_gir() has duplicated entry for
dependencies parameter. As a fix, this patch removes the entry added
recently.
