Description Tomáš Hrnčiar 2020-11-19 12:22:19 UTC
python-qrcode fails to build with Python 3.10.0a2.

+ for m in $modules
+ /usr/bin/python3 -c 'import qrcode.image.pil'
free(): invalid pointer

RPM build errors:
/var/tmp/rpm-tmp.mJ26Ax: line 40:   247 Aborted                 (core dumped) /usr/bin/python3 -c "import $m"
error: Bad exit status from /var/tmp/rpm-tmp.mJ26Ax (%check)

For all our attempts to build python-qrcode with Python 3.10, see:

Testing and mass rebuild of packages is happening in copr. You can follow these instructions to test locally in mock if your package builds with Python 3.10:

Let us know here if you have any questions.

Python 3.10 will be included in Fedora 35. To make that update smoother, we're building Fedora packages with early pre-releases of Python 3.10.
A build failure prevents us from testing all dependent packages (transitive [Build]Requires), so if this package is required a lot, it's important for us to get it fixed soon.
We'd appreciate help from the people who know this package best, but if you don't want to work on this now, let us know so we can try to work around it on our side.

Tomáš, I suspect PIL (pillow) is broken. See also bz1898977 and bz1896390.

so PIL itself compiles, just its dependents are broken?
