It is possible that the subproject has been downloaded already, in that
case there is no reason to not use it. If the subproject has not been
downlaoded already it will fail do_subproject().
This comes up now and again when people try do do something like:
meson.build:
```meson
my_sources = ['foo.c']
subdir('subdir')
executable('foo', my_sources)
```
subdir/meson.build:
```meson
my_sources += ['bar.c']
```
The code our projects care about verifying coverage for mostly lives in
the source_root with the exception of the generated source files in
build_root. This change cleans up the output so we don't have prefixed
paths on our source files anymore.
This doesn't touch everything as it's just based on the python3 module
tests, ported to the python module. It's still better than the one very
basic test in the unit test module.
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.
Since `_process_libs` appends the lib's dependencies this list already,
the final return value of `_process_libs` will end up after its
dependencies, which is the wrong way around. (The lib must come first,
then its dependencies)
The easiest solution is to simply pre-pend the return value of
`_process_libs` rather than appending it, so that its dependencies come
after the library itself.
Closes#4091.
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.
If you change only some project in meson.build,
only that .vcxproj file will be updated and reloaded.
If you change something not related to VS solution and projects
or simply touch the meson.build file, nothing will be reloaded.
Starting with VS 2017, `Platform` is not always set (f.ex., if you use
VsDevCmd.bat directly instead of vcvars*.bat), but `VSCMD_ARG_HOST_ARCH`
is always set, so try that first.
