Package: cmake Version: 3.25.1-1 Severity: minor Tags: patch User: ubuntu-de...@lists.ubuntu.com Usertags: origin-ubuntu ubuntu-patch X-Debbugs-Cc: sl...@ubuntu.com
Dear Maintainer, cmake fails to execute its buildtime tests (dh_auto_test) on many architectures when compiled with an LTO enabled toolchain. E.g. on Ubuntu/s390x (GCC-12 + LTO) we saw the following failure: # CustomCommand test fails (LP: #2015872): # No INFO:symbol[pcStatic] found in: /<<PKGBUILDDIR>>/Build/Tests/CustomCommand/bin/libpcStatic.a # Instead it produces the following strings (`strings bin/libpcStatic.a | grep INFO`): # INFO:symbol[] # INFO:symbol[pcStatic] We also observed failures on amd64, arm64 and ppc64el in addition to s390x: https://git.launchpad.net/ubuntu/+source/lto-disabled-list/commit/?h=ubuntu/devel&id=57f7f783 This does not directly affect Debian, but might, should Debian enable LTO by default in the future. Please consider disabling LTO explicitly to avoid such (future) failure, or feel free to reject this patch if you feel like it doesn't apply. * d/rules: Disable LTO to fix FTBFS (LP: #2015872) Thanks for considering the patch. -- Lukas -- System Information: Debian Release: bookworm/sid APT prefers jammy-updates APT policy: (500, 'jammy-updates'), (500, 'jammy-security'), (500, 'jammy'), (100, 'jammy-backports') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.19.0-38-generic (SMP w/8 CPU threads; PREEMPT) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled
