stdout line matching supports count since commit
66d62a224e to fail if certain output is
present (count: 0) but it was never documented in the contribution
guidelines.
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.
Android requires shared modules that use symbols from other shared
modules to be linked before they can be dlopen()ed in the correct
order. Not doing so leads to a missing symbol error:
https://github.com/android/ndk/issues/201
We need to always allow linking for this. Also add a soname, although
it's not confirmed that it's needed, and it doesn't really hurt if it
isn't needed.
We currently cannot make this work because inside dependency() we don't
know the current subproject. We would also like the optional but
extremely useful location node, but we don't have that either...
Convert the broken code to a FIXME for visibility.
Use a derived type when passing `subproject` around, so that mypy knows
it's actually a SubProject, not a str. This means that passing anything
other than a handle to the interpreter state's subproject attribute
becomes a type violation, specifically when the order of the *four*
different str arguments is typoed.
On Windows using MSYS2 MinGW installing the package `mingw-w64-x86_64-wxmsw3.1` provides `wx-config-3.1`. I have tried building my software by making this exact change and it build correctly.
Do not quit from using pytest at all, when pytest is present, simply
because xdist isn't available. Even without xdist, pytest is still
useful.
There doesn't seem to be any particular reason to require xdist. It just
happens to have been implemented that way, back in commit
4200afc74d when we originally added a
check to avoid pytest erroring out with unknown options when xdist
options are passed and xdist is not installed.
The $CI environment variable may be generally set by Github or Gitlab
actions, and is not a reliable indicator of whether we are running "CI".
It could also, for an absolutely random example that didn't *just
happen*, be Alpine Linux's attempt to enable the Meson testsuite in
their packaging, which... uses Gitlab CI.
In this case, we do want to perform normal skipping on not-found
requirements. Instead of checking for $CI, check for $MESON_CI_JOBNAME
as we already use that in all of our own CI jobs for various reasons.
This makes it easier for linux distros to package Meson without
accumulating hacks like "run the testsuite using `env -u CI`".
Fixes regression in commit 05b5a1e56f.
This added usage of another module in the python module's introspection
of `meson.exe runpython`, but the MSI packaging didn't adapt, causing it
to fail to be detected due to ImportError.
Fixes#9975
We do not want anyone touching this entire directory tree, but due to
the way it was implemented, we only checked if its direct parent was a
subproject violation. This generally worked, unless people tried to add
`subprojects/` as an include directory.
Patch this hole. It now provides the same warning any sandbox violation
does (but is not currently an error, just a "will become an error in the
future").
In commit b30dddd4e5, various refactorings
were done, during which a kwarg got accidentally dropped from the
function that determined part of the log message. As a result, a ':'
suddenly appeared in the log message where none should be.
Example expected output:
Checking if "-Werror=shadow with local shadowing" compiles: YES
What actually happened:
Checking if "-Werror=shadow with local shadowing" : compiles: YES
Fixes#9974
RuntimeError is way too generic when we have an explicit class for
"Meson reports to the user, something went wrong".
Moreover we now tell people that generic exceptions are "Meson bugs and
should be reported", so our failure to do the technically correct thing
and report the right kind of exception means we get haunted by demons of
confusion. Specifically, people complain to us that Meson told them
"there is a bug in Meson" when their install fails due to meson.build or
build environment issues.
This bring us in line with Autotools and CMake and it is useful
for platforms like Nix, which install projects
into multiple independent prefixes.
As a consequence, `get_option` might return absolute paths for some
directory options, if a directory outside of prefix is passed.
This is technically a backwards incompatible change but its effect
should be minimal, thanks to widespread use of `join_paths`/`/` operator
and pkg-config generator module. It should only cause an issue when
a path were constructed by concatenating the value of directory path option.
Also remove a comment about commonpath since we do not use that since
<00f5dadd5b>.

The first version of setuptools to properly support pyproject.toml was 42 (40-41 were buggy). It is also necessary to specify `build-backend = "setuptools.build_meta"`, otherwise you get the (horrible) default `build-backend = "setuptools.build_meta:__legacy__"`.
This adds 3.10 (didn't check to see if it was tested on 3.10, that should be done, but I'm using it on 3.10).
setup_requires is deprecated and should be producing warnings on modern setuptools, and never worked for setuptools anyway - setuptools can't update itself, and setuptools is what is reading this anyway!
This will really help with pipx run, as `pipx run meson[ninja]` will now work on any system with pipx 0.17 or newer, no dependencies required. This now includes GitHub Actions, which just updated to pipx 1.0.0. Pipx run lets you use recent (always <1 week old) versions of anything on PyPI.
This has never worked for built/found programs, only for script files.
In commit 2fabd4c7dc scripts learned an
attribute stating which subproject they came from. In commit
3990754bf5 dist scripts learned to run
even from a subproject, and relied on that attribute to know when, in
fact, they came from a subproject.
Unfortunately the original attribute was only set in one half of an
if/else, and the other half returned early with only part of the work
done.
Fixes#9964
In commit 0deab2ee9e we added the ability
to pass a declare_dependency() to any compiler method that accepts
"dependencies", but we never marked the version it is available since.
Fixes#9957
The array of licenses is not clear, where and SPDX expression using AND
and OR is very clear, take for example this: `['Apache', 'GPLv2']`. What
does that mean? Any Apache license you like and GPLv2? Using a valid
SPDX license identifier however makes it extremely clear what is meant:
`'Apache-2.0 OR GPL-2.0-only'`. It is very clear that you mean, "this is
Apache 2.0, however, you can use as GPL-2.0 for the purpose of linking
it into your GPL-2.0 project".
For static library crates that depend on other internal static library
crates, all link_with targets get promoted to link_whole targets. Due to
a bug, only link_with targets are considered when generating a Rust
target for the ninja backend. This made it impossible to link a Rust
static library with another internal Rust static library.
This change fixes that issue by chaining link_whole_targets with
link_targets, just like many other languages within the ninja backend.
This is gross and looks terrible, but I'm not entirely sure how else to
do this.
And cmake is an inferior methodology, TBH, since it is effectively the
same as our own builtins. However, cmake also handles some bizarre
Windows library names whose provenance I'm not entirely sure of, in
addition to implementing the usual excessive pattern of hardcoded search
directories. So, this may be useful, at least on Windows, as a fallback.
(I am not really interested in offering feature compatibility with cmake
for a bunch of bizarre naming schemes that ***aren't the official cmake
library names***, so if cmake allows that and people really feel they
need it, all the more power to them.)
Nevertheless, I believe if it got found via our system dependency class,
it will always provide results which are just as functional as cmake.
cmake can only find openssl installations that would otherwise be
missed.
This also avoids the case where users did
```
dependency('OpenSSL', modules: [...], method: 'cmake')
```
and expected it to work, since our builtin dependency supersedes the
divergent case and didn't previously allow the cmake method. I don't
know why they would do such a thing, but who knows... it is always
possible.
On some platforms, this is provided by the base system, which
nevertheless refrains from providing the .pc files that go along with
it. As a result, it's impossible to sensibly find these dependencies.
I'm looking at you, FreeBSD...

This is also a problem on macOS, but that's unfixable (and I believe
they provide some truly ancient and out-of-support version anyway) and
you probably want to use the homebrew OpenSSL. Still, meson can now
detect these old versions and even set their version number.
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.
This was a nice idea in theory, but in practice it had various problems:
- On the only platform where ldconfig is expected to be run, it is
really slow, even when the user uses a non-default prefix and ldconfig
doesn't even have permission to run, nor can do anything useful due to
ld.so.conf state
- On FreeBSD, it bricked the system: #9592
- On cross builds, it should not be used and broke installing, because
ldconfig may not be runnable without binfmt + qemu: #9707
- it prints weird and confusing errors in the common "custom prefix"
layout: #9241
Some of these problems can be or have been fixed. But it's a constant
source of footguns and complaints and for something that was originally
supposed to be just "it's the right thing to do anyway, so just do it
automatically" it is entirely too risky.
Ultimately I do not think there is justification for keeping this
feature in since it doesn't actually make everyone happy. Better for
users to decide whether they need this themselves.
This is anyways the case for cmake and autotools and generally any other
build system, so it should not be too intimidating...
Fixes#9721
Store in TestSerialisation whether a particular test must always be logged
verbosely. This is particularly useful for long-running tests or when a
single Meson test() is wrapping an external test harness. In this case,
TAP can be used by the external harness and Meson will log each subtest as
it runs.

Basically the last thing we did during target processing was to generate
shlib symlinks for e.g. libfoo.so -> libfoo.so.1.
In some cases we would dispatch to another function and return early,
though, which meant we never got far enough to generate the symlinks.
This then led to breakage when people tried to compile against libfoo.so
This surely breaks -uninstalled.pc usage, and also caused problems in
https://github.com/rust-lang/rust/pull/90260
Regressed in commit bfb12222c3.
This needs to iterate over all methods, process them, and add them to a
list. Instead, it deleted all methods, processed all remaining methods,
and appended them to the in-use iterator.
Use a second list, instead.
