When install_dir was set for a shared_library, the import library
would not be installed at all, which is unintended.
Instead, install it into the custom directory if it is set, otherwise
install it in the default import library installation directory.
Includes a test for this.
You can now pass a list of strings to the install_dir: kwarg to
build_target and custom_target.
Custom Targets:
===============
Allows you to specify the installation directory for each
corresponding output. For example:
custom_target('different-install-dirs',
output : ['first.file', 'second.file'],
...
install : true,
install_dir : ['somedir', 'otherdir])
This would install first.file to somedir and second.file to otherdir.
If only one install_dir is provided, all outputs are installed there
(same behaviour as before).
To only install some outputs, pass `false` for the outputs that you
don't want installed. For example:
custom_target('only-install-second',
output : ['first.file', 'second.file'],
...
install : true,
install_dir : [false, 'otherdir])
This would install second.file to otherdir and not install first.file.
Build Targets:
==============
With build_target() (which includes executable(), library(), etc),
usually there is only one primary output. However some types of
targets have multiple outputs.
For example, while generating Vala libraries, valac also generates
a header and a .vapi file both of which often need to be installed.
This allows you to specify installation directories for those too.
# This will only install the library (same as before)
shared_library('somevalalib', 'somesource.vala',
...
install : true)
# This will install the library, the header, and the vapi into the
# respective directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : ['libdir', 'incdir', 'vapidir'])
# This will install the library into the default libdir and
# everything else into the specified directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : [true, 'incdir', 'vapidir'])
# This will NOT install the library, and will install everything
# else into the specified directories
shared_library('somevalalib', 'somesource.vala',
...
install : true,
install_dir : [false, 'incdir', 'vapidir'])
true/false can also be used for secondary outputs in the same way.
Valac can also generate a GIR file for libraries when the `vala_gir:`
keyword argument is passed to library(). In that case, `install_dir:`
must be given a list with four elements, one for each output.
Includes tests for all these.

The MSVC static library tool, lib.exe, does not understand the same set
of arguments as the linker. Avoid a warning by not adding /DEBUG or /PDB
to the command line when invoking lib.exe
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:

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.

https://bugs.python.org/issue3770https://github.com/mesonbuild/meson/issues/1323
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
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.
