This patches takes the options work to it's logical conclusion: A single
flat dictionary of OptionKey: UserOptions. This allows us to simplify a
large number of cases, as we don't need to check if an option is in this
dict or that one (or any of 5 or 6, actually).
D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.
Fixes#7082
As stated by the doc, default to install python sources to purelib
location, as they should not depend on platform.
This also fixes discrepancy between get_install_dir() and
install_sources() locations.

- ExternalProgramHolder has path() method while CustomTargetHolder and
BuildTargetHolder have full_path().
- The returned ExternalProgramHolder's path() method was broken, because
build.Executable object has no get_path() method, it needs the
backend.
- find_program('overridden_prog', version : '>=1.0') was broken because
it needs to execute the exe that is not yet built. Now assume the
program has the (sub)project version.
- If the version check fails, interpreter uses
ExternalProgramHolder.get_name() for the error message but
build.Executable does not implement get_name() method.
Currently PkgConfig takes language as a keyword parameter in position 3,
while the others take it as positional in position 2. Because most
dependencies don't actually set a language (they use C style linking),
using a positional argument makes more sense. ExtraFrameworkDependencies
is even more different, and duplicates some arguments from the base
ExternalDependency class.
For later changes I'm planning to make having all of the dependencies
use the same signature is really, really helpful.
If the Python binary that we find doesn't return valid JSON when asked to run a
small script, show the command being ran and stdout/stderr in meson-log.txt.
Fixes: #5914
This mirrors the modules keyword argument that some dependencies (such
as qt and llvm) take. This allows an easier method to determine if
modules are installed.
In most cases instead pass `for_machine`, the name of the relevant
machines (what compilers target, what targets run on, etc). This allows
us to use the cross code path in the native case, deduplicating the
code.
As one can see, environment got bigger as more information is kept
structured there, while ninjabackend got a smaller. Overall a few amount
of lines were added, but the hope is what's added is a lot simpler than
what's removed.
For dynamic linking, some mingw releases don't link
correctly with pythonXX.lib in all cases.
This patch forces mingw to link against
pyhthonXX.dll instead of the .lib file, which has
a better compatiblity.
Note that msys 1.0 old platform is detected
as windows instead of 'mingw'
This would normally be exposed by the ExternalProgramHolder, but wasn't
due to the implementation of the PythonInstallation module. Because of
that I've duplicated the method so that we can add the FeatureNew
decorator.
Fixes#4070
Into a generic interpreter object. This isn't a module, it's an object
returned by a module, it also happens to be a special case of an
ExternalProgram, which is a normal interpreter object. Let's treat it
like one.
Windows requires things to be linked, on macOS distutils doesn't link by default.
On Linux etc. things are not so clear, some distros like Debian patch distutils to not link,
some don't. In addition the manylinux wheels spec prohibits linking against libpython
and upstream is thinking about changing the default:
https://bugs.python.org/issue34814
Call into distutils to figure out what distutils does and in case it doesn't link
against libpython replace the passed in Python dependency with a partial one.
When dependency(), find_library(), find_program(), or
python.find_installation() return a not-found object and disabler is
true, they return a Disabler object instead.
* Lookup is now performed according to the following order:
1. use `pkg-config` with `PKG_CONFIG_LIBDIR=LIBPC` from python
2. use plain `PKG_CONFIG_{LIBDIR,PATH}` from the environment
3. try to extract the information from SYSCONFIG
The second step is necessary for relocated python installations
and cross compilation scenarios, where the value of `LIBPC` might
be wrong.
Meson tries to find the interpreter path through the "py" launcher on Windows in all
cases which breaks if meson is run under MSYS2 and an official CPython is installed as well.
MSYS2 Python doesn't install a py launcher which results in meson finding the system one instead
even though python2/python3 is in PATH.
Always check if the interpreter name is in PATH before falling back to checking the py launcher.
All dependencies were using find_library, has_header, get_define, etc on
self.compiler assuming that it's a compiler that outputs and consumes
C-like libraries. This is not true for D (and in the future, for Rust)
since although they can consume C libraries, they do not use the
C ecosystem.
For such purposes, we now have self.clib_compiler. Nothing uses
self.compiler anymore as a result, and it has been removed.
pypy installations don't usuallyy ship with pkg-config files,
we thus need to replicate what their version of distutils does.
In addition, we also try our best to build against other
pythons that do not have pkg-config files.
What is actually defined here varies wildly on different python-versions
for different platforms.
On my python2.7 on Windows len(sysconfig.get_config_vars()) returns 17,
whereas in my Ubuntu that number is 517!
Hence it is useful to be able to check which keys are available, as
well as allowing specifying a default option.
