--- Comment #4 from Evangelos Foutras <evangelos at foutrelis dot com> --- Thank you for looking into this. :) I applied your diff on top of binutils 2.38 and was able to successfully build libheif and nextcloud-client with it. Previously, these two Arch Linux packages (and probably a lot more) would fail to link to several system libraries (x265, de265, snappy). PS: Not sure if this is of any importance, but I also noticed the following linker error when building nextcloud-client with unpatched binutils 2.38 (likely has the same root cause and fix as the undefined references seen earlier, and this error is gone as well after applying your patch): /usr/bin/ld: /usr/lib/libQt5Gui.so.5.15.2: unexpected redefinition of indirect versioned symbol `_ZTI11QSharedData@Qt_5' -- You are receiving this mail because: You are on the CC list for the bug.
