Just to collect information in this bug, the fPIC requirement and fPIE banning in Qt now is because of this: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65886
This bug originally however is about a problem that shows up when that related Bsymbolic option is enabled on armhf too. This needed forcing but we forced it at one point since it was believed the toolchain bug was fixed. However, for now it remains disabled on non-x86 (the default of Qt upstream) because of the persisting bug, but it may be re-enabled later if the bug is resolved. The toolchain bug (fPIC + Bsymbolic misbehaving on arm) is last described at https://bugreports.qt.io/browse/QTBUG-47350 ** Bug watch added: GCC Bugzilla #65886 https://gcc.gnu.org/bugzilla/show_bug.cgi?id=65886 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1403758 Title: Unity8 shows black screen with Qt 5.4.0 To manage notifications about this bug go to: https://bugs.launchpad.net/binutils/+bug/1403758/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
