CMake has two target properties, LINK_OPTIONS and INTERFACE_LINK_OPTIONS.
The former is for link flags that apply only to the target (PRIVATE).
The latter is used for link flags that propagate to dependents (PUBLIC
or INTERFACE). Meson currently propagates all flags, PUBLIC and PRIVATE,
as part of the generated dependency() which causes problems when some of
the private flags are highly disruptive, e.g. `-Wl,--version-script`.
Tease apart the two kinds of link flags and, for non-static libraries,
only propagate the PUBLIC/INTERFACE flags and not the PRIVATE ones.
This reverts commit 9f02d0a3e5.
It turns out that this does introduce a behavioral change in existing
users of ConfigurationData, which it wasn't supposed to (it was supposed
to preserve behavior there, and add a new *warning* for
EnvironmentVariables).
This breaks projects such as pulseaudio, libvirt, and probably more.
Roll back the change and try again after 1.5.0 is released.
Fixes: #13372
When trying to get the version of a program, meson was previously
hardcoded to run the binary with `--version`. This does work with the
vast majority of programs, but there are a few outliers (e.g. ffmpeg)
which have an unusual argument for printing out the version. Support
these programs by introducing a version_argument kwarg in find_program
which allows users to override `--version` with whatever the custom
argument for printing the version may be for the program.
Cargo.lock is essentially identical to subprojects/*.wrap files. When a
(sub)project has a Cargo.lock file this allows automatic fallback for
its cargo dependencies.
New people that want to use Meson for building Python extensions most
probably will read Python module docs first. Direct them to meson-python
and suggest to set `python.install_env=auto`.
When running our integration tests in systemd we depend on each test
having a unique name. This is always the case unless --repeat is used,
in which case multiple tests with the same name run concurrently which
causes issues when allocating resources that use the test name as the
identifier.
Let's set MESON_TEST_ITERATION to the current iteration of the test so
we can use $TEST_NAME-$TEST_ITERATION as our test identifiers which will
avoid these issues.
This uses objfw-config to get to the flags, however, there's still
several todos that can only be addressed once dependencies can have
per-language flags.
The docs didn't really explain what the issue was with using it. And
it's not actually a "crash" either way.
The FeatureNew mentions that "name" is new, but it is standard for
these warnings to tell you both the type of object you're operating on
and the name of the method that is an issue. This omitted the former,
and was very confusing.
This is very similar to --gdb, except it doesn't spawn GDB, but
connects stdin/stdout/stderr directly to the test itself. This allows
interacting with integration tests that spawn a shell in a container
or virtual machine when the test fails.
In systemd we're migrating our integration tests to run using the
meson test runner. We want to allow interactive debugging of failed
tests directly in the virtual machine or container that is spawned
to run the test. To make this possible, we need meson test to connect
stdin/stdout/stderr of the test directly to the user's terminal, just
like is done with the --gdb option.
Only Environment and ConfigurationData are mutable. However, only
ConfigurationData becomes immutable after first use which is
inconsistent.
This deprecates modification after first use of Environment object and
clarify documentation.
Adds a howto section describing how to put files in a separate build
target and override the unity build setting, and why you might want to
do this.
Closes: #13031
This fixes issues where a new option is added, an option is removed, the
constraints of an option are changed, an option file is added where one
didn't previously exist, an option file is deleted, or it is renamed
between meson_options.txt and meson.options
There is one case that is known to not work, but it's probably a less
common case, which is setting options for an unconfigured subproject.
We could probably make that work in some cases, but I don't think it
makes sense to download a wrap during meson configure.
The test.json format currently has three keys related to skipping tests:
* `skip_on_jobname`
* `skip_on_os`
* `skip_on_env`
While `skip_on_env` marks the test itself as skipped, i.e. they don't get run when the
conditions are met, the other two skip options are just marking the test as "expected to be skipped"
if the conditions apply, i.e. they want to see `MESON_SKIP_TEST` in the output and things will
fail if that doesn't happen. They don't actually skip the tests as the names imply.
To make this clearer rename the keys:
* `skip_on_jobname` -> `expect_skip_on_jobname`
* `skip_on_os` -> `expect_skip_on_os`
`skip_on_env` stays the same, since that actually skips.
The docs were also confused about this, so adjust that too.
