The sysconfig config variables are different on MSYS2 and the paths
are also different. We now also use the full path to the import or
static library instead of using -Lfoo -lpython35 etc.
Also obey the value of the 'static' keyword argument.
sysconfig.get_platform() returns 'mingw' with MSYS2, so we need to
use some other method; in this case I chose to use the CC that
Python was compiled with, which is a relatively reliably indicator
unless people start using Python on Windows compiled with Clang or
something.
/usr/bin/env does not exist on Haiku since there's no /usr. The actual
location is /bin/env. Detect that case and directly use the
interpreter being passed to `env` in the shebang.
Also reorganize the Windows special cases which does the same thing.
The MinGW toolchain can read MinGW paths, but Python cannot and we
sometimes need to parse the libs and cflags manually (for static-only
library searching, for instance). The MinGW toolchain can always read
Windows paths with `/` as path separater, so just use that.
Also try harder to find a compiler that dependencies can use.
This means that in C++-only projects we will use the C++ compiler for
compiler checks, which can be important.
We can't know if the .lib is a static or import library, but that's
a problem in general too. The only way to figure out if a specific
file is an import or a static library is to dump its symbols and check
if it starts with __imp or not.
Even then, some libs are hybrid import and static, i.e., they contain
references to DLLs for some symbols and also provide implementations
for other symbols so this is a difficult problem.

MSVC cannot handle MinGW-esque /c/foo paths, convert them to C:/foo.
We cannot resolve other paths starting with / like /home/foo so leave
them as-is so the user gets an error/warning from the compiler/linker.
These paths are commonly found in pkg-config files generated using
Autotools inside MinGW/MSYS and MinGW/MSYS2 environments.
Currently this is only done for PkgConfigDependency.
As the Vala compiler does not define thread_flags() and
thread_link_flags(), depending on threads in any capacity will cause Meson to
fail.
Fixes#2720.
Currently, we only consider the build depends of the Executable being
run when serializing custom targets. However, this is not always
sufficient, for example if the executable loads modules at runtime or if
the executable is actually a python script that loads a built module.
For these cases, we need to set PATH on Windows correctly or the custom
target will fail to run at build time complaining about missing DLLs.
One thing that makes cross compiling with meson a pain is the need for
cross files. The problem is not with cross files themselves (they're
actually rather brilliant in that they allow for a much greater deal of
flexibility than autotools hardcoded paths approach) but that each user
needs to reimplement them themselves, when for most people what they
really want is a cross file that could be provided by their distro, all
they really want is the correct toolchain.
This patch is the first stop to making it easier for distros to ship
their own cross files (and for users to put their's somewhere safe so
they don't get `git clean`ed. It allows the cross files (on Linux and
*BSD) to be stored in home and system paths (~/.config/meson/cross,
/usr/share/meson/cross, and /usr/local/share/meson/cross), and to be
loaded by simply by specificying --cross-file.
With this patch meson will check the locations its always checked first,
(is cross file absolute, or is it relative to $PWD), then will check
~/.config/meson/cross, /usr/local/share/meson/cross,
/usr/share/meson/cross, (or $XDG_CONFIG_PATH and $XDG_DATA_DIRS) for the
files, raising an exception if it cannot find the specified cross file.
Fixes#2283
When `ninja -C builddir/ test` is run, ninja will change into the build
dir before starting, but `meson test -C builddir/` does not. This is
important because meson does not use (for good reasons) absolute paths,
which means if a test case needs to be passed as an argument a file name
that is part of the build process, it will be relative builddir. Without
changing into the builddir the path will not exist (or worse, point at
the wrong thing), and test will not behave as intended.
To fix this mtest will change directory before starting tests, and will
change back after all tests have been finished.
Fixes#2710
This exposes the already existing UserStringArrayOption class through
the meson_options.txt. The intention is to provide a way for projects to
take list/array type arguments and validate that all of the elements in
that array are valid without using complex looping constructrs.
While finding an external program, we should only split the shebang
once since that is what Linux and BSD also do. This is also why
everyone uses #!/usr/bin/env in their shebangs since that allows
you to run an interpreter in a path with spaces in it.
See `man execve` for more details, specifically the sections for
interpreter scripts.
Depending on the tool (moc, uic, rcc, lrelease), the Qt version
(4.8, 5.7, 5.9) and the distribution (Fedora, debian,...) it seems you
cannot predict which of -v or -version will be supported.

Currently passing a bad combo or array option, providing a non-boolean
to a bool arg, or a host of other things can cause an traceback from a
MesonException, don't do that.
Fixes#2683
Although some other base types like boolean objects can be expresed
as strings, this is not possible with int objects.
This patch adds support to express int values as strings as hex,
decimal or octal values.
