Package: cmake
Version: 3.25.1-1
Severity: minor
Tags: patch
User: [email protected]

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.
