9 gcc-9 (9.3.0-1) unstable; urgency=medium ... 16 * Stop shipping the include-fixed directory. ... 20 -- Matthias Klose <d...@debian.org> Thu, 12 Mar 2020 15:24:59 +0100 Arr I should learn to read versions more in depth, it in fact IS different: ii libgcc-9-dev:amd64 9.2.1-30ubuntu2 amd64 GCC support library (development files) vs ii libgcc-9-dev:s390x 9.3.0-1ubuntu2 s390x GCC support library (development files) So this change broke us and probably many things. Unless there is a twist to it I'm yes missing. Marking it critical for gcc-9 which is the source this built from and assigning to doko who did the uploads. ** Changed in: glibc (Ubuntu) Status: New => Confirmed ** Changed in: gcc-9 (Ubuntu) Status: New => Confirmed ** Changed in: glibc (Ubuntu) Status: Confirmed => Invalid ** Changed in: linux (Ubuntu) Status: Incomplete => Invalid ** Changed in: gcc-9 (Ubuntu) Importance: Undecided => Critical ** Changed in: gcc-9 (Ubuntu) Assignee: (unassigned) => Matthias Klose (doko) ** Summary changed: - FTFBS in Focal armhf/ppc64/s390x + Almost global FTFBS due to dropping include-fixed dir in 9.3.0-1 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1867316 Title: Almost global FTFBS due to dropping include-fixed dir in 9.3.0-1 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chrony/+bug/1867316/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
