--- Comment #6 from Evangelos Foutras <evangelos at foutrelis dot com> --- (In reply to H.J. Lu from comment #5) > It may be a GCC 11.1 bug. Are you referring to the error about _ZTI11QSharedData@Qt_5 in my last comment, or the original issue? The system libQt5Gui was indeed built with GCC 11.1 but the error came from building nextcloud-client with GCC 11.2 and binutils 2.38. It also went away after applying your earlier diff. If you meant the original issue: I'm using GCC 11.2. I grabbed heif_info-heif_info.o from the failed libheif build so generating its proproccessed source counterpart isn't very straightforward for me. However, I can provide a repro.sh that builds libheif from source and reproduces the undefined references on GCC 11.2 + binutils 2.38; would that help? -- You are receiving this mail because: You are on the CC list for the bug.
