When using binutils's windres, we can instruct it to invoke the preprocessor
in such a way that it writes a depfile, so that dependencies on #included
files are automatically tracked.
Not implemented for MSVC tools, so skip testing it in that case.
This new unit test will use the targets in '198 install_mode' and
confirm that every file and directory gets the expected mode, ensuring
that the setting is properly applied at install time.
When using an install_mode in install_subdir(), that should apply to the
files and not to the directory tree.
Otherwise, an install_mode not including the executable bit will make
the tree inaccessible, since directories need it to be traversed.
If the mode needs to be applied to both files and directories, then
install_subdir() is only useful to install files with the executable bit
set, which is not really that useful...
So default to just using the umask for the directories and applying
install_mode to the files only.
This can be reviewed in the future, possibly by adding a separate
install_dir_mode attribute, or perhaps adding an optional fourth field
to FileMode with the mode for directories (this is similar to how RPM
handles specifying mode of directory trees recursively added to the
package.)
For the VS backend, assertRebuiltTarget() asserts the that target is both
recompiled and relinked. This isn't correct for test_rc_depends_files, as
changing the rc script's dependencies only causes the executable to be
relinked, and not to also have it's source recompiled.
assertRebuiltTarget already gets this right for the ninja backend.
Expose depend_files: from the custom_target this creates.
This is the change suggested in #2815, with tests and documentation added.
Fixes#2789 (duplicate #2830)
Instead of using fragile guessing to figure out how to invoke meson,
set the value when meson is run. Also rework how we pass of
meson_script_launcher to regenchecker.py -- it wasn't even being used
With this change, we only need to guess the meson path when running
the tests, and in that case:
1. If MESON_EXE is set in the env, we know how to run meson
for project tests.
2. MESON_EXE is not set, which means we run the configure in-process
for project tests and need to guess what meson to run, so either
- meson.py is found next to run_tests.py, or
- meson, meson.py, or meson.exe is in PATH
Otherwise, you can invoke meson in the following ways:
1. meson is installed, and mesonbuild is available in PYTHONPATH:
- meson, meson.py, meson.exe from PATH
- python3 -m mesonbuild.mesonmain
- python3 /path/to/meson.py
- meson is a shell wrapper to meson.real
2. meson is not installed, and is run from git:
- Absolute path to meson.py
- Relative path to meson.py
- Symlink to meson.py
All these are tested in test_meson_commands.py, except meson.exe since
that involves building the meson msi and installing it.
There are cases when it is useful to wrap the main meson executable with
a script that sets up environment variables, passes --cross-file, etc.
For example, in a Yocto SDK, we need to point to the right meson.cross
so that everything "just works", and we need to alter CC, CXX, etc. In
such cases, it can happen that the "meson" found in the path is actually
a wrapper script that invokes the real meson, which may be in another
location (e.g. "meson.real" or similar).
Currently, in such a situation, meson gets confused because it tries to
invoke itself using the "meson" executable (which points to the wrapper
script) instead of the actual meson (which may be called "meson.real" or
similar). In fact, the wrapper script is not necessarily even Python, so
the whole thing fails.
Fix this by using Python imports to directly find mesonmain.py instead
of trying to detect it heuristically. In addition to fixing the wrapper
issue, this should make the detection logic much more robust.
This will copy the file to the build directory without trying to read
it or substitute values into it.
Also do this optimization if the configuration_data() object passed to
the `configuration:` kwarg is empty, and print a warning about it.

The fallback might be not used not only because it couldn't be found, but
also because something went wrong trying to use it.
Also, update a test which relies on the specific text
We were setting it to a file list that would always be wrong, and
always out of date since it would never exist.
However, the output list is not predictable. It usually has a 1-1
relationship with the input XML files, but it may not.
This must be fixed later with API for users to provide the output
names.

pypy installations don't usuallyy ship with pkg-config files,
we thus need to replicate what their version of distutils does.
In addition, we also try our best to build against other
pythons that do not have pkg-config files.
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:

Unit test was asserting that
"meson --bindir=foo --bindir=bar" must succeed and
"meson configure --bindir=foo --bindir=bar" must fail.
There should be no difference between those 2 command lines.
In this case it's fine to have it twice because there is no ambiguity,
second overrides the first, that's done by python's argparse.
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.
This test copies a src tree using umask of 002, then runs the build and
install under umask 027. It ensures that the default install_umask of
022 is still applied to all files and directories in the install tree.
This way they override all other arguments. This matches the order of
link arguments too.
Note that this means -I flags will come in afterwards and not override
anything else, but this is correct since that's how toolchain paths
work normally too -- they are searched last.
Closes https://github.com/mesonbuild/meson/issues/3089
The linkers currently do not support ninja compatible output of
dependencies used while linking. Try to guess which files will be used
while linking in python code and generate conservative dependencies to
ensure changes in linked libraries are detected.
This generates dependencies on the best match for static and shared
linking, but this should not be a problem, except for spurious
rebuilding when only one of them changes, which should not be a problem.
Also makes sure to ignore any libraries generated inside the build, to
keep the optimisation working where changes in a shared library only
cause relink if the symbols have changed as well.
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.
