The default behavior of installing relative to prefix may be unexpected,
and is definitely wrong in many cases.
Give users control in order to specify that yes, they actually want to
install to a venv.
This is particularly useful for projects that use meson as a build
system for a python module, where *all* files shall be installed into
the python site-packages.
Automatically generate additional variables and write them into the
generated pkg-config file.
This means projects no longer need to manually define the ones they
use, which is annoying for dataonly usages (it used to forbid setting
the base library-relevant "reserved" ones, and now allows it only for
dataonly. But it's bloat to manualy list them anyway).
It also fixes a regression in commit
248e6cf473 which caused libdir to not be
set, and to be unsettable, if the pkg-config file has no libraries but
uses the ${libdir} expansion in a custom variable. This could be
considered likely a case for dataonly, but it's not guaranteed.
CMake's write_basic_package_version_file has supported since version 3.14
an ARCH_INDEPENDENT option that makes it skip its architecture check in
the Version file.
With this patch Meson now supports it as well, and the change is also
compatible with older CMake versions, as they will simply ignore the
option.
This also slightly changes the contents of the generated Version file
when arch_independent is not set: previously, the if() needed to skip
the arch check was always filled with an empty string, while CMake puts
"FALSE" (or "TRUE") in it. Now, that if() will always be filled with
either "False" or "True", better matching CMake's behaviour.
Because we don't want to pass the Interpreter kwargs into the build
layer. This turned out to be a mega commit, as there's really on elegant
way to make this change in an incremental way. On the nice side, mypy
made this change super easy, as nearly all of the calls to
`CustomTarget` are fully type checked!
It also turns out that we're not handling install_tags in custom_target
correctly, since we're not converting the boolean values into Optional
values!
This was allows up to 0.61.0 (including with the initial type
annotations), but was accidentally broken by fixes for other bugs in
0.61.1.
Fixes: #9883
If the found python returns None from sysconfig.get_config_var('LIBPC')
then we cannot (and don't) set PKG_CONFIG_LIBDIR from it. In fact, we
can virtually guarantee we won't find a PkgConfigDependency either,
because any python that doesn't have a LIBPC is presumably not installed
to the system pkg-config directory (maybe it's an isolated relocatable
install, maybe it just doesn't have pkg-config support for who knows
what reason).
Trying to find one anyway using pkg-config's builtin search paths can
unexpectedly succeed, though, by finding a completely unrelated python
installation installed to a system location, which isn't the one we are
actually building for.
Instead, return early so that we use the system dependency class
fallback.
While we are at it, add back the debug messages from #3989 which got
removed.
There is the problem of the annotations themselves, then there is
the problem with depends being mutated. The mutation side effect is a
problem in itself, but there's also the problem that we really want to
use Sequence, which isn't mutable.
This is a layering violation, we're relying on the way the interpreter
handles keyword arguments. Instead, pass them as free variables,
destructuring in the interpreter
It used to support:
- a single string
- an array of anything
And as long as CustomTarget supported it too, everything worked fine.
So, a `files('foo')` worked but a `files('foo')[0]` did not, which is
silly... and it's not exactly terrible to use files() here, the input is
literally a list of source files.
Fixes building gnome-terminal
Fixes#9827
Test updated by Nirbheek Chauhan <nirbheek@centricular.com>
The original attempted fix only allowed configuration to succeed, but
not building. It was modeled based on the gdbus-codegen documentation,
which states:
--annotate WHAT KEY VALUE WHAT KEY VALUE WHAT KEY VALUE
Add annotation (may be used several times)
which clearly indicates that gdbus-codegen accepts an --annotate flag
that is followed by a multiple of 3 values, despite this not actually
working.
The manpage actually contradicts the --help text:
--annotate ELEMENT KEY VALUE
Used to inject D-Bus annotations into the given XML files. []
... and gives examples that use multiple --annotate flags each with 3
arguments.
To better understand what meson is supposed to do here, we should look
at ef52e60936, which ported to
typed_kwargs. There is actually a big chunk of code to handle
annotations that got completely dropped, leading with a comment (that
did not get dropped): "they are a list of lists of strings..."
Reimplement this logic inside a validator/converter for the annotations
kwarg container:
- do not listify, we don't accept `annotations: ''` and listify is
supposed to be for when either x or list[x] is valid
- go back to checking for a list of exactly 3 values
- allow a list of the aforementioned, in the traditionally expected
form:
[
['foo1', 'foo2', 'foo3'],
['bar1', 'bar2', 'bar3'],
]
- pass one --annotate flag per 3-value-list
And add some better error reporting for the cause of errors when
processing lists of lists.
As soon as we check for args[1] we declare it is of type FileOrString,
and the additional ones specified in the `sources` kwarg explicitly
allow this. It makes no sense to not accept it as the posarg too.
Fixes building tracker-miners.
Fixes gtk3 build, which uses typesfile.
All these arguments are processed by a function that explicitly handles
both str and File, and converts them to absolute paths. They clearly
need to handle File objects.
Per the gdbus-codegen documentation, this "may be used several times",
and it is:
- a valid use case
- used that way in the wild
Fixes building at least geoclue2, gdm.
Regression in commit 566c2c9a9c.
The interpreter details are a bit of black magic. Functions expect
tuples, but they receive lists and then the type-checking decorators
convert those to tuples.
So, directly manhandling a self._interpreter.func_*() but passing it the
tuple it nominally expected, actually explodes in your face by way of
failing an assert, then dumping 'ERROR: Unhandled python exception'.
Fixes use of gnome.gtkdoc(..., check: true), for example when building
glib.
It is unmaintained, broken (frequently for long periods of time) and not
really required for any meson functionality. Its purpose is to be used
as a one-shot tool for creating a distro package recipe, and then
deleted from your meson.build files.
Due to its fragile dependency on coredata implementation details, we
cannot assume it will reliably work, or continue to work, without
someone who is actively willing to take responsibility for it.
Even if that were to happen, this might be better off as an external
script that parses introspection data.
Closes#9764Closes#9763
This is basically a rewrite of the gnome.yelp target to remove the
ad-hoc script, which generates multiple issues, including meson
not knowing which files were installed.

When generating pkgconfig file for a library that links to an
uninstalled static library built by custom_target() Meson was crashing
when trying to access some attributes that does not exist on that class.
Also fix is_internal() implementation, it only really make sense on a
CustomTargetIndex or if CustomTarget has only a single output.
