This issue still exists with dev-python/pycparser-2.19 unfortunately i confirm this error with pycparser-2.19. it happens on kodi-18.4 from portage (~amd64): https://forums.gentoo.org/viewtopic-t-1101978-highlight-.html with an unsupported plugin: https://github.com/CastagnaIT/plugin.video.netflix It is reported to have sth. to do with optimization-flags: https://github.com/eliben/pycparser/issues/291) but compiling python-2.7 and all related pkgs with CFLAGS="-march=x86-64 -mtune=k8 -O0 -fomit-frame-pointer -pipe" CXXFLAGS="${CFLAGS}" LDFLAGS="" LDDFLAGS="" changed absolutely nothing: https://github.com/CastagnaIT/plugin.video.netflix/issues/219 i'll go back to pycparser-2.17 and see if that works. This issue still exists with dev-python/pycparser-2.19-r1 for and additional information, I have PYTHONOPTIMIZE=2 environment variable set. When I emerge it with PYTHONOPTIMIZE=0, it compiles. How do you install with PYTHONOPTIMIZE=0 ? I'm not seeing any examples in portage. I ended up doing a `pip install pycparser --user` to get rid of my error for now. you can set per-package env variables. Check https://wiki.gentoo.org/wiki//etc/portage/package.env for a detailed description. But neither using PYTHONOPTIMIZE=0 nor PYTHONDONTWRITEBYTECODE=1 fixed this issue for me. Deleting all *.pyo manually after the merge fixed it, though: find /usr/lib/python2.7/site-packages/pycparser/ -name '*.pyo' -delete Created attachment 649166 [details] Kodi script.extendedinfo callstack (In reply to Daniel Hiepler from comment #5) > > Deleting all *.pyo manually after the merge fixed it, though: > > find /usr/lib/python2.7/site-packages/pycparser/ -name '*.pyo' -delete I can confirm, only this solved the issue for me. See attached the error log for ExtendedInfo script. Cleanup of bugs open for old versions. |
With media-tv/kodi-9999 (I strongly suspect this also happens with media-tv/kodi-17.6-r1 as well, but haven't tested it) and dev-python/pycparser-2.18.1-r1, when a Youtube video is shared to Kodi using Yatse, the video does not play, an error is shown on screen, and this error is logged in Kodi's log: ------ 17:25:50.569 T:139685905950464 ERROR: ERROR: start symbol translation_unit_or_empty undefined 17:25:50.571 T:139685905950464 ERROR: EXCEPTION Thrown (PythonToCppException) : -->Python callback/script returned the following error<-- - NOTE: IGNORING THIS CAN LEAD TO MEMORY LEAKS!

This issue appears to be the same problem reported upstream at https://github.com/eliben/pycparser/pull/198 It also seems to be the same root cause as bug 628386 Also, perhaps useful information: Kodi uses python 2.7.
