After implementing a much more extensive Java native module than what
currently exists in the tests, I found shortcomings.
1. You need to be able to pass multiple Java files.
2. Meson needs more information to better track the generated native
headers.
3. Meson wasn't tracking the header files generated from inner classes.
This new function should fix all the issues the old function had with
room to grow should more functionality need to be added. What I
implemented here in this new function is essentially what I have done in
the Heterogeneous-Memory Storage Engine's Java bindings.
The point of a .use() function is because we don't always have the
information we need to use a feature check, so we allow creating the
feature and then storing it for later use. When implementing location
checks, although it is optional, actually using it violated that design.
Move the location out of the init method for FeatureCheck itself. It
remains compatible with all cases of .single_use(), but fix the rest up.
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
