Building matplotlib 2.2.4 on my system always (AFAICT) results in one of two possible build failures. Building with MAKEOPTS="-j1" works around the issue and allows the build to finish. Possible failure #1: /usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: /var/tmp/portage/dev-python/matplotlib-2.2.4/work/matplotlib-2.2.4-python3_7/build/temp.linux-x86_64-3.7/src/py_converters.o: file not recognized: file truncated Possible failure #2 (which of course I can't seem to reproduce anymore) which was during the early part of the build phase, going from memory: OPTIONAL BACKEND EXTENSIONS macosx: no [Mac OS-X only] qt5agg: no [skipping due to configuration] qt4agg: no [skipping due to configuration] gtk3agg: yes [installing, version 3.11.24] gtk3cairo: no [tool timeout] Reproducible: Always Steps to Reproduce: 1. emerge -1av dev-python/matplotlib Things I've noticed: - it's *always* with py37, never any of the other 3 python implementations I have (27, 35, 36) - it's *always* the py_converters.o file (with the build failure #1), no other compiled file or lib fails - it's *always* gtk3cairo that fails (with build failure #2)
Created attachment 601738 [details] build.log for failure #1

quite a few such libraries are failing. pandas, scipy, matplotlib... all py37 related https://bugs.gentoo.org/699966 has some supporting info

At the risk of sounding like a stuck record, this bug is FIXED for ~amd64 but very much still broken for stable amd64 users, who are now hitting it firmly as Python 3.7 is stable and they have to rebuild all their python packages, including matplotlib-2.2.2-r1 which is the stable version. matplotlib-2.2.2-r1 needs the same fix as has been applied to version 2.2.4 applying to make it work on amd64 stable.
