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
Co-authored-by: Dylan Baker <dylan@pnwbakers.com>
* 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.
Co-authored-by: Dylan Baker <dylan@pnwbakers.com>
* Update add_compcert_compiler.md
Added a sentence about the state of the implementation (experimental); use proper markdown
* properly separate arguments

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.
