[meta-python][PATCH v2 1/4] python_mesonpy.bbclass: New class

[meta-python][PATCH v2 1/4] python_mesonpy.bbclass: New class

[Zoltán Böszörményi]

Some python modules (e.g. SciPy, scikit-image) use meson-python
(a.k.a. mesonpy) in pyproject.toml:

    [build-system]
    build-backend = 'mesonpy'

This class, together with python3-meson-python and its dependencies
will allow building such modules.

[meta-python][PATCH v2 2/4] python3-patchelf: New recipe

[Zoltán Böszörményi]

Dummy module to indicate the presence of patchelf.
Used by python3-meson-python.

The CMakeLists.txt file is a crippled copy from this patchelf
python module's sources, removing almost everything, and
adding a dummy install target, so do_install() doesn't fail.

I’m not sure I’d call this a dummy package.

If you’re not building native code with cmake then you don’t need this, just switch skbuild to setuptools.

Use subdir=${S} to put the CMakeLists.txt in the right place instead of doing this.

However, this recipe doesn’t build patchelf and doesn’t have any python code. So what’s the point of it?

If there are packages which depend on this, either patch out that dependency (as we can just DEPEND on patchelf-native) or write the few lines of pyproject.toml to ship an empty package directly.

The python_mesonpy class depends on meson and ninja, so those can be removed.

Also the python3-ninja recipe is another waste of time and space, and should be removed.

This might break nativesdk where we also write cross files.

Does mesonpy actually look for patchelf and ninja modules *at runtime*, or does it just use $PATH? If the latter you can depend on the actual binaries instead of the wrappers.

I still don’t see why you need to split the meson class up.

See the other thread. For some reason, meson always wins
regardless of the inheritance order, so do_configure has
meson_do_configure instead of pep517_do_configure, etc.

Add a new do_configure to your class which simply calls the right one.

It still doesn't work. meson_do_qa_configure fails with this:

Naturally, as running meson's configure stage went from
do_configure to do_compile indirectly via "nativepython3 -m build ..."

Sorry, there seems to be no way around it but splitting out the
environment setup from meson.bbclass into meson-common class.
If you don't like the "-common" naming, I can rename it to
meson-env.bbclass or something like that.

I will still rework python3-meson-python to not require
the dummy patchelf python module and review other
comments and make necessary changes.

Thanks.

This construct also doesn't work
===================================
inherit meson
do_configure[postfuncs]:remove = "meson_do_qa_configure"
===================================

It results in an "unparsed line" error. So, I have to re-iterate this:
