In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.
The documentation for this change was left out of its implementation in
commit b4aee4675a and was later documented
in commit f831c05b55 as if it had always
existed.
When using pkg.generate(mylib, library : publicdep) it is pretty clear
we don't want to associate publicdep to this generated pkg-config file.
This is a small behaviour break in theory, but also fixes real bug in
the case publicdep is later used to generate another pkg-config file
that does not depend on mylib, that would write a wrong `Requires:
mylib` in the genarated pkg-config file.
This fix unavoidable deprecation warning when glib is cross built
for Android. Glib does `pkg.generate(libglib, libraries : [libintl],
...)` which wrongly associates libintl to the generated glib-2.0.pc, so
when later it generates gio-2.0.pc file that depends on libglib, it will
warn about libintl being associated with libglib. This does not happen
in normal glib build because libintl is usually provided by glibc and is
only an internal library when it fallbacks to a subproject.
Since `_process_libs` appends the lib's dependencies this list already,
the final return value of `_process_libs` will end up after its
dependencies, which is the wrong way around. (The lib must come first,
then its dependencies)
The easiest solution is to simply pre-pend the return value of
`_process_libs` rather than appending it, so that its dependencies come
after the library itself.
Closes#4091.
- Add libraries from InternalDependency.libraries
- Deprecate association of libraries from the "libraries" keyword
argument to the generated pkg-config file.
If a project generates a single pc file but multiple shared libraries
with dependencies on each other, the generated pc name will be used to
generate a Requires.private dependency, which means the project will
depend on itself. This breaks at least some versions of pkg-config
(0.27 in RHEL7) which cannot handle the recursion and error out.
When adding the dependency using the pc name, check that it's not
on the project itself.
Fixes#4583
this adds support for generating pkgconfig files for c#.
The difference to c and cpp is that the -I flag is not known to the c#
compiler, but rather the -r flag which is used to link a .dll file into
the compiled library.
However this opens the question of validating which pkgconfig files can
be generated (depending on the language).
This implements 4409.
We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
* Add a test case for bad de-dup of -framework args
https://github.com/mesonbuild/meson/issues/3800
* pkgconfig: Don't naively de-dup all arguments
Honestly don't know what I was smoking. Of course the `Libs:` field in
a pkg-config file can have arguments other than -l and -L

* pkgconfig module: Fix needlessly aggressive de-dup
Libraries that have been linked with link_whole: are internal
implementation details and should never be exposed to the outside
world in either Libs: or Libs.private:

The fix for Requires generation in #3406 missed a second code path with the same
problem.
Passing a pkgconfig dependency to requires would produce Q, t, 5, C, o,r, e'
instead of 'Qt5Core'.
This was introduced in 8efd940.
Previously pkg-config files generated by the pkgconfig modules for static libraries
with dependencies could only be used in a dependencies with `static: true`.
This was caused by the dependencies only appearing in Libs.private even
if they are needed in the default linking mode. But a user of a
dependency should not have to know if the default linking mode is static
or dynamic; A dependency('somelib') call should always pull in all
needed pieces into the build.
Now for meson build static libraries passed via `libraries` to the generate
method automatically promote dependencies to public.
It is weird and inconsistent to have different pc file depending on
default_library value when using library() or build_target(). We should
skip dependencies only when user explicitly want shared library only.
Whilst working on the Reproducible Builds effort [0], we noticed
that meson creates non-reproducible pkgconfig files as it relies
on Python set ordering.
This was originally filed in Debian as #892515 [1].

Currently only not found deps implicitly pulled from a Library object
are ignored. We should also ignore not found deps passed directly to
generate() method.
This makes the unit testing more complicated because libfoo pkgconfig
dependency cannot be found when generated from the within the same
meson.build.
Special case ThreadDependency by taking compiler's flags and
PkgConfigDependency by adding them in requires(.private) instead. For
other Dependency objects just take their link_args and compile_args.
Closes#2725
The install_dir parameter of the libraries can also contain the
prefix path, which creates wrong library paths in the .pc file.
This patch detects if prefix is contained in the library path
and creates a relative path.
Fixes#2469
Without specifying a custom install directory string, get_custom_install_dir() returns True. So for the `Libs` entry I was getting this:
Libs: -L${prefix}/True -lfoo
Now it behaves as expected:
Libs: -L${libdir} -lfoo
This also adds a "# noqa: F401" comment on an unused "import lzma",
which we are using it in a try/except block that is being used to
check if the lzma module is importable; of course it is unused.
v2: This turned out to be a little tricky.
mesonbuild/modules/__init__.py had the "unused" import:
from ..interpreterbase import permittedKwargs, noKwargs
However, that meant that the various modules could do things like:
from . import noKwargs # "." is "mesonbuild.modules"
Which breaks when you remove __init__.py's "unused" import. I
could have tagged that import with "# noqa: F401", but instead I
chose to have each of the module import directly from
"..interpreterbase" instead of ".".
