Earlier, we would replace the subproject option with the parent
project's option, which is incorrect if the types are not the same.
Now we retain the subproject's option and print a warning. It's not
advisable to issue an error in this case because subproject option
yielding is involuntary for the parent project (option names can match
because of coincidences).
Shared modules may be resource-only DLLs, or might automatically
self-initialize using C constructors or WinMain at DLL load time.
When an import library is not found for a shared module, just print
a message about it instead of erroring out.
Fixes#3965
Otherwise we get an error while checking the subproject version:
Uncomparable version string 'none'.
If the dependency was found as a not-found dependency in the
subproject and is not required, just take it.
Meson already had code to propagate link dependencies from static
libraries to programs that use those static libraries.
Unfortunately, it was not handling the special cases of 'threads' and
'openmp' dependencies.
For some reason this was missing, but it should've always existed
since cc.find_library() returns an object that is internally an
ExternalDependency instance.
Paths provided to us by the user or by pkg-config can be (and must be)
assumed to be usable since they might not be usable standalone.

It's possible that the configuration data object has components added
conditionally, and that sometimes an empty configuration data object
is passed on purpose.
Instead, we do the substitution and also warn if no tokens were found
that could've been substituted.

We now pass the current subproject to every FeatureNew and
FeatureDeprecated call. This requires a bunch of rework to:
1. Ensure that we have access to the subproject in the list of
arguments when used as a decorator (see _get_callee_args).
2. Pass the subproject to .use() when it's called manually.
3. We also can't do feature checks for new features in
meson_options.txt because that's parsed before we know the
meson_version from project()
This is a special type of option to be passed to most 'required' keyword
arguments. It adds a 3rd state to the traditional boolean value to cause
those methods to always return not-found even if the dependency could be
found.
Since integrators doesn't want enabled features to be a surprise there
is a global option "auto_features" to enable or disable all
automatic features.
Added method concatenate_string_literals to CCompiler. Will concatenate
string literals.
Added keyword argument 'concatenate_string_literals' to Compiler.get_define.
If used will apply concatenate_string_literals to its return value.
Input files can be in any file encoding, not just utf-8 or isolatin1. Meson
should not make assumptions here and allow for the user to specify the
encoding to use.
This is a simple test case, checking for installed_files.txt, which just
makes sure the syntax is accepted.
Manual tests confirmed the permissions were set correctly.
A follow up commit adds a unit test based on this directory.
This checks not only for existence, but also for usability of the
header, which means it does a full compilation and not just
pre-processing or __has_include.
Fixes https://github.com/mesonbuild/meson/issues/2246
Simplify support for alternate bases using int(..., base=0) which
auto-detects it using the standard Python syntax for numbers.
Octal numbers are useful to specify permission bits and umasks.
Binary numbers are not super useful... But considering we get them for
free, let's allow them here too.
v2: Tweak the regex so it doesn't accept a decimal number with a leading
zero, which is invalid for int(..., base=0) and would raise a ValueError
if passed around.
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.

For now dicts are immutable, and do not expose any methods,
they however support "native" syntax such as [] lookup,
and foreach iterating, and can be printed.
It seems that some projects relied on the previously buggy
behaviour of accepting a 2-element list as the single argument
to configuration_data.set().
Special-case this behaviour, and emit a deprecation message.
When passing more than one -Dc_args it should override the value
instead of appending. This is how all other options works.
Value should be split on spaces using shlex just like it does with
CFLAGS environment variable.
Fixes#3473.
