Packaging ansible-builder for SLES15 with python310: How to properly build subunit (aka python310-subunit) for SLES15 using the Python3-SLE-Module?
Hi all, ansible-builder pulls in python-subunit somewhere in the chain. As I am already building the other ansible-* tools for Leap 15 / SLES15 using the Python3-SLE-Module, I tried packaging ansible-builder too. I managed to get subunit (branched from Factory) to build. But only because I butchered it. :-) Forgot for now that I had to disable the %checks. I added a BuildRequires for the python base module, as the configure step did not find a proper python interpreter. (The project is setup to only build against python3.10, as most of the tools require something a lot newer than 3.6. So no python3.6 is installed at first). But that did not help. It still complained, although /usr/bin/python3.10 was existing. I guess it is looking for something called "python3". So I also added python3-base. Which made the configure happy, but that somehow feels wrong. I want to avoid that somehow python3.6 is being used for building this package. What would be the proper way? Patch the configure step to accept the python3.10 executable? I know that is not something usual, but to not interfere with the standard python installation python3.10 does not provide /usr/bin/python3 and I am fine with that. I just would like to avoid errors in this package. Thanks in advance!

subunit or ansible-builder?

Decent configuration systems have a way to provide the path to the python executable and libraries/headers (from python3X-devel). Sometimes it is enough to provide PYTHON=/usr/bin/python3.10 or similar. If that is not the case yet, consider adding a patch and submit it upstream.

OK, I'll have a look, thanks. Johannes -- Johannes Kastl Linux Consultant & Trainer Tel.: +49 (0) 151 2372 5802 Mail: kastl@b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg http://www.b1-systems.de GF: Ralph Dehner Unternehmenssitz: Vohburg / AG: Ingolstadt,HRB 3537

I may have missed it in the large number of macros, but is there a macro that contains the paths like /usr/bin/python3.10? One that is set based on the %pythons definition?

The best I could come up with was using export PYTHON=/usr/bin/python%{python_version} Kind Regards, Johannes -- Johannes Kastl Linux Consultant & Trainer Tel.: +49 (0) 151 2372 5802 Mail: kastl@b1-systems.de B1 Systems GmbH Osterfeldstraße 7 / 85088 Vohburg http://www.b1-systems.de GF: Ralph Dehner Unternehmenssitz: Vohburg / AG: Ingolstadt,HRB 3537

Don't do this. You never really know what the flavor-agnostic %python_version might be by default. https://github.com/openSUSE/python-rpm-macros#flavor-specific-macros There are a couple of options: If you have just python310, nothing else: export PYTHON=%__python310 If you iterate of multiple flavors in %pythons: %{python_expand # iterate over all flavors in buildset. Special macro handling of "$python"! # $python is python3.10 here export PYTHON=$(command -v $python) # $python is python310 here export PYTHON=%{__$python} # Do your configure and build steps inside the expand make }
Kind Regards, Johannes

I am not sure what is needed for subunit. It is not a pure python package, but has python subpackages:
https://build.opensuse.org/project/show/home:ojkastl_buildservice:branches:d...
To me it looked like the configure only runs once. And apparently it picks python3 on Tumbleweed, so I daresay it is enough that it finds a python, but it does not fail if it is "the wrong one".
%configure \ --enable-shared \ --disable-static
%make_build %pyproject_wheel
I will gladly rework the SR, no problem.

I see now. The problems don't arise from the python subpackages but from the configuration of the non-python stuff. Any python3 interpreter will be good for it. export PYTHON=$(find %_bindir -name 'python3*[0-9]' -print -quit) The wheel and installed python subpackages (%files %{python_files python-%{name}}) are pure python. Nothing to configure there, no need to have it in the same expand iteration as the configure.
