It's fairly common on Linux and *BSD platforms to check for these
attributes existence, so it makes sense to me to have this checking
build into meson itself. Autotools also has a builtin for handling
these, and by building them in we can short circuit cases that we know
that these don't exist (MSVC).
Additionally this adds support for two common MSVC __declspec
attributes, dllimport and dllexport. This implements the declspec
version (even though GCC has an __attribute__ version that both it and
clang support), since GCC and Clang support the MSVC version as well.
Thus it seems reasonable to assume that most projects will use the
__declspec version over teh __attribute__ version.
Fixes:
meson.build:6:0: ERROR: Uncomparable version string 'unknown'.
This was previously partially fixed in a8694f4b, which only fixed it
for cached fallback dependencies.
With this it is now possible to do
foobar = executable('foobar', ...)
meson.override_find_program('foobar', foobar)
Which is convenient for a project like protobuf which produces both a
dependency and a tool. If protobuf is updated to use
override_find_program, it can be used as
protobuf_dep = dependency('protobuf', version : '>=3.3.1',
fallback : ['protobuf', 'protobuf_dep'])
protoc_prog = find_program('protoc')
Allowing to use the new "feature" option type and allowing not to fail
on subproject if it is not necessary to fail.
By default subprojects are "required" so previous behaviour is not
changed.
Fixes#3880
The fallback to compilers.base_options was done after optname is changed
to have subproject prefix. Simplify the code by looping over all
dictionaries and only keep user_options separate because that one is
special.
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).
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.
Needs a `mock` kwarg to Interpreter to not do any parsing of build
files, but only setup the builtins and functions.
Also consolidate the documentation and data tests into one class.
Ninja buffers all commands and prints them only after they are
complete. Because of this, long-running commands such as `cargo
build` show no output at all and it's impossible to know if the
command is merely taking too long or is stuck somewhere.
To cater to such use-cases, Ninja has a 'pool' with depth 1 called
'console', and all processes in this pool have the following
properties:
1. stdout is connected to the program, so output can be seen in
real-time
2. The output of all other commands is buffered and displayed after
a command in this pool finishes running
3. Commands in this pool are executed serially (normal commands
continue to run in the background)
This feature is available since Ninja v1.5

We already have code to fetch and find binaries specified in a cross
file, so use the same code for exe_wrapper. This allows us to handle
the same corner-cases that were fixed for other cross binaries.
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.
Instead of just printing the message in the exception, if it's
a MesonException, also print the file and the line number. If it's an
unknown exception, print the entire traceback so that we can pin-point
what the Meson bug causing it is.
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()
* Use _get_callee_args to unwrap function call arguments, needed for
module functions.
* Move some FeatureNewKwargs from build.py to interpreter.py
* Print a summary for featurenew only if conflicts were found. The
summary now only prints conflicting features.
* Report and store featurenew/featuredeprecated only once
* Fix version comparison: use le/ge and resize arrays to not fail on
'0.47.0>=0.47'
Closes https://github.com/mesonbuild/meson/issues/3660
A number of cases have to be taken care of while doing this, so
refactor it into a helper on ExternalProgram and use it everywhere.
1. Command is a list of len > 1, use it as-is
2. Command is a list of len == 1 (or a string), use as a string
3. If command is an absolute path, use it as-is
4. If command is not an absolute path, search for it
This is accepted by all other binaries in the cross file. With this
change, we also don't check whether the specified command exists at
configure time, but that's probably a feature anyway.

D is not a 'c-like' language, but it can link to C libraries. The same
might be true of Rust in the future and Go when we add support for it.
This contains no functionality changes.
Make a custom target output dir as an include dir relative to @BUILD_ROOT@,
so that path is constructed correctly when using the absolute path forms
used by the MSVC backend.
