In this case, the arguments to MinGW windres will contain spaces and
the test will definitely fail, so just skip it.
This effectively means that manually running the test will be fine, but
running it via run_project_tests.py will always fail (skip).
Added and tested on MSYS2/MinGW which doesn't implement the required
semaphore locks in the multiprocessing module:
Traceback (most recent call last):

ImportError: cannot import name 'sem_unlink'
During handling of the above exception, another exception occurred:

ImportError: This platform lacks a functioning sem_open implementation, therefore, the required synchronization primitives needed will not function, see issue 3770.

According to 3770, the same problem also exists on OpenBSD, so this
will potentially also be useful there.
The actual fix is quite involved (#1526), so just disable this for now
since it's much worse to not be able to generate static libraries at
all vs a minor bug in static libraries getting stale objects (#1356)
Closes https://github.com/mesonbuild/meson/issues/1517
Points to the `mesonintrospect.py` script corresponding to the
currently-running version of Meson.
Includes a test for all three methods of running scripts/commands.
Closes https://github.com/mesonbuild/meson/issues/1385
This reduces our CI running time by roughly half without compromising
much test coverage by much. We can mostly safely assume that very few
Meson bugs will be arch-specific with Visual Studio.
Now as long as you have a C compiler available in the project, it will
be used to compile assembly even if the target contains a C++ compiler
and even if the target contains only assembly and C++ sources.
Earlier, the order in which sources appeared in a target would decide
which compiler would be used.
However, if the project only provides a C++ compiler, that will be
used for compiling assembly sources.
If this breaks your use-case, please tell us.
Includes a test that ensures that all of the above is adhered to.
Use an ordered dict for the compiler dictionary and sort it according
to a priority order: fortran, c, c++, etc.
This also ensures that builds are reproducible because it would be
a toss-up whether a C or a C++ compiler would be used based on the
order in which compilers.items() would return items.
Closes https://github.com/mesonbuild/meson/issues/1370
The "1 + 2" swift sanity check produces a swiftc compiler warning
(result unused). For this sanity check, compile a print statement as is
done with fortran.
My first patch, so update authors.txt as well.
The paths are already relative to the target dir.
Includes a test for this which generates and builds in subdirs. If all
the generation and usage is done in the build root, this bug will
obviously not be triggered.
An empty / no-op dependency can be expressed as []. This works with
the dependencies kwarg in executable targets such as shared_library,
but now with declare_dependency, where it would error out with
"error: Dependencies must be external deps" because the deps are
not flattened in this case. This patch fixes that.
Fixes#1500
and column are printed out by other parser code.
Add a print of the line with the error, and where on the line the error
occurred.
Add a print of where the block scope started, if the error is due to
missing the block scope end token.
Special wrap modes:
nofallback: Don't download wraps for dependency() fallbacks
nodownload: Don't download wraps for all subproject() calls
Subprojects are used for two purposes:
1. To download and build dependencies by using .wrap files if they
are not provided by the system. This is usually expressed via
dependency(..., fallback: ...).
2. To download and build 'copylibs' which are meant to be used by
copying into your project. This is always done with an explicit
subproject() call.
--wrap-mode=nofallback will never do (1)
--wrap-mode=nodownload will do neither (1) nor (2)
If you are building from a release tarball, you should be able to
safely use 'nodownload' since upstream is expected to ship all
required sources with the tarball.
If you are building from a git repository, you will want to use
'nofallback' so that any 'copylib' wraps will be download as
subprojects.
Note that these options do not affect subprojects that are git
submodules since those are only usable in git repositories, and you
almost always want to download them.
This will benefit projects such as GNOME Recipes that prefer using
submodules over wraps because it's easier to maintain since git is
aware of it, and because it integrates with their existing
workflow. Without this, these projects have to manually initialize
the submodules which is completely unnecessary.

Also use a pathlib.Path object for the checks since it does I/O only
once and is much more efficient anyway. Path objects are available
since Python 3.4, so this is fine.
Besides fixing output capture, it also fixes a strange bug in MSBuild
where if the command list is too long, it will remove random
characters from the command list before passing it to the command.
Closes https://github.com/mesonbuild/meson/issues/1417
For newer VS versions, we can simply rely on 'VisualStudioVersion' being
set in the environment.
For VS2010, we fall back to check 'VSINSTALLDIR' for the version string.
If the backend can not be auto detected, we raise an exception to make the
user choose an explicit backend.
We also print the detected backend to the meson log.
We were adding them to the CompilerArgs instance in the order in which
they are specified, which is wrong because later dependencies would
override previous ones. Add them in the reverse order instead.
Closes https://github.com/mesonbuild/meson/issues/1495
The 'Visual Studio 2017' image does not include VS2010, so we have to use
the 'Visual Studio 2015' image by default and only use the 2017 image for
msvc2017 compiler tests.
VS2017 requires the 'WindowsTargetPlatformVersion' property to be set.
We gather the version to use from the environment variable
'WindowsSDKVersion' that will be set by the VS developer command prompt.
