Cygwin executables are still loaded by the Windows PE loader, so PATH needs
to include any extra directories where required DLLs can be found.
Cygwin uses a unix style ':'-separated PATH. os.pathsep is used correctly
on extra_paths in meson_exe.py, but not in mesontest.py
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.

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.

We check for the existence of PDB files in the install script, so we
don't need to do all this mucking about here. That's more robust too
because we don't need to parse build arguments in buildtype=plain
and decide if the PDB file would be generated.
Otherwise if the list of sources changes on reconfigure after building,
the static library will contain both the old and new objects.

A user may want to add libraries to link with in the (c|cpp)_link_args
property of the cross-compile file.
Those libraries should be at the end of the command line due to reference
resolution mechanism of the compiler.
By moving the cross_args after LINK_ARGS we are sure that specific
cross-compilation libraries are at the end of the command line.
See [github PR #1363](https://github.com/mesonbuild/meson/pull/1363) to
have the context of this change.
Also, now the linker options are added from various sources in the same
order as compiler arguments for compile commands. As a result, all
libraries and library paths from external and internal sources are added
after all the linker options have been added.
As a result option_link_args() are added when libraries are added to the
list since currently the only thing they add are the libraries specific
in cpp_winlibs/c_winlibs. This fixes an issue where compilation with the
MinGW toolchain (which uses static libraries for winlibs) would result
in undefined symbol errors because the static libraries would be added
in the very beginning and hence would not be scanned for symbols.
Detailed comments have been added that explain where each option is
coming from and why it's been added at that specific point.
More improvements are necessary here because we currently still
unnecessarily repeat libraries from dependencies over and over, which
is a major problem in gst-build because inter-subproject dependencies
cause linker command-lines to almost exceed the argument list length
limit imposed by the kernel. It is also causing us to unnecessarily
add static libraries which have already been linked into a shared
library. See: self.build_target_link_arguments()
At the same time, also fix the order in which compile arguments are
added. Detailed comments have been added concerning the priority and
order of the arguments.
Also adds a unit test and an integration test for the same.
Always generate the vcxproj file, but only add it to the build
configuration if it's either supposed to be built by default, or is
a dependency of another target that is built by default.
Previously, build_by_default=false targets would not be built at all
even if they were used in a test (as the exe or as a command-line
argument) which would lead to a test failure.
Now we look into all the defined tests and add all CustomTargets and
BuildTargets used in them to the list of build_by_default targets.
The purpose of this class is to make it possible to sanely generate
compiler command-lines by ensuring that new arguments appended or added
to a list of arguments properly override previous arguments.
For instance:
>>> a = CompilerArgs(['-Lfoo', '-DBAR'])
>>> a += ['-Lgah', '-DTAZ']
>>> print(a)
['-Lgah', '-Lfoo', '-DBAR', '-DTAZ']
Arguments will be de-duped if it is safe to do so. Currently, this is
only done for -I and -L arguments (previous occurances are removed when
a new one is added) and arguments that once added cannot be overriden
such as -pipe are removed completely.
With the 'install_mode' kwarg, you can now specify the file and
directory permissions and the owner and the group to be used while
installing. You can pass either:
* A single string specifying just the permissions
* A list of strings with:
- The first argument a string of permissions
- The second argument a string specifying the owner or
an int specifying the uid
- The third argument a string specifying the group or
an int specifying the gid
Specifying `false` as any of the arguments skips setting that one.
The format of the permissions kwarg is the same as the symbolic
notation used by ls -l with the first character that specifies 'd',
'-', 'c', etc for the file type omitted since that is always obvious
from the context.
Includes unit tests for the same. Sadly these only run on Linux right
now, but we want them to run on all platforms. We do set the mode in the
integration tests for all platforms but we don't check if they were
actually set correctly.
Added IntelCompiler, IntelCCompiler and IntelCCompiler.
environments.py has been changed to detect icc and icpc.
ninjabackend changed for proper pch generation.
ICC 17.0.0 does not support C++13 (that's why default arguments tests fails).
Test 25 object extraction fails due to some unescaped whitespaces.
Some test with vala fail because of successful build, although they
should fail, as warning do not exit with failure.
