blosc 1.8.3 installing to purelib directory not platlib

[toddrme2178]

I am trying to package python-blosc for openSUSE Linux and I am running into an issue where the package is installing to the architecture-independent purelib directory rather than the architecture-specific platlib directory. This is incorrect, since it contains compiled C code. Specifically, it is being installed into:

/usr/lib/python3.7/site-packages/blosc

Instead of

/usr/lib64/python3.7/site-packages/blosc

This didn't happen in 1.8.1, so it seems to be something new with the switch to scikit-build.

Yes, using scikit-build is probably the reason why this is happening. @thewtex do you have some suggestion here?

@toddrme2178 what command is used to install the package?

@thewtex see here:
https://build.opensuse.org/package/view_file/devel:languages:python:numeric/python-blosc/python-blosc.spec?expand=1

%python_exec setup.py install -O1 --skip-build --force --root %{buildroot} --install-purelib=%{$python_sitearch}

I guess the --install-purelib parameter is a hack to override the install into $python_sitelib

[toddrme2178]

@thewtex The command I used that didn't work was:

python3 setup.py build_ext --inplace
python3 setup.py build
python3 setup.py install -O1 --skip-build --force --root=%{buildroot} --prefix=%{_prefix}

The version @bvnavigator showed above is indeed a hack to workaround this issue by forcing the purelib package to be installed in platlib.

@toddrme2178 @bnavigator the next place to look is

https://github.com/scikit-build/scikit-build/blob/0c33f15b0c0452e8bd70ab6057b4d283d6025b51/skbuild/command/install.py#L20-L23

if it is possible to debug the state and path taken there.

[FrancescAlted]

Is this a problem anymore?
