Subject: gnucap: ftbfs with LTO (link time optimization) enabled

Date: Tue, 19 Jul 2022 16:52:37 +0000

Package: src:gnucap
Version: 1:0.36~20171003-1.1
Severity: minor
Tags: sid bookworm
User: [email protected]
Usertags: ftbfs-lto

This package currently fails to build (at least on the amd64
architecture) with link time optimizations enabled.  For a background
for LTO please see

https://wiki.debian.org/ToolChain/LTO

The goal is to enable this optimization by default in an upcoming
Debian release in dpkg-buildflags for 64bit architectures.  The goal
is to get this package to build with link time optimizations, or to
explicitly disable link time optimizations for this package build.

To reproduce the build failure, enable the lto optimization in
testing/unstable by adding "optimize=+lto" to DEB_BUILD_MAINT_OPTIONS
in the debian/rules file, or if this macro is unset, just set it:

export DEB_BUILD_MAINT_OPTIONS = optimize=+lto

Please try to fix the build with lto enabled, fixing the packaging or
forwarding the issue upstream. If the issue cannot be fixed,
explicitly disallow building the package with lto by adding to your
rules file:

export DEB_BUILD_MAINT_OPTIONS = optimize=-lto

or adding that string to your existing setting of DEB_BUILD_MAINT_OPTIONS.

The full build log can be found at:
http://qa-logs.debian.net/2022/06/09/dpkglto/gnucap_0.36~20171003-1.1_unstable_dpkglto.log
The last lines of the build log are at the end of this report.

Hi all.

The package fails to build due to a static construction order issue that
has been fixed upstream in 2020. This is unrelated to LTO. I set
optimize=+lto anyway, and it works (dpkg-dev 1.21.9).

Could anyone please upload 20210107 [1]? I don't have permission..

best wishes
felix

Closes: 1015418
Changes:
 gnucap (1:20230520-dev-1) experimental; urgency=medium
 .
   * New development snapshot
   * follow change in version numbering
     package version is now YYYYMMDD
   * use autotools
     - simpler rules
     - fixed -dbg packages
   * libgnucap-dev: add dependency on corresponding default plugins
   * drop d/compat, depend on debhelper-compat 13 instead
     - require-root: no
     - d/not-installed
   * debian/control: Bump Standards-Version to 4.5.0
     Checked against
     https://www.debian.org/doc/packaging-manuals/upgrading-checklist.txt
   * leave abi version and soname untouched. It's experimental.
   * hardwire CXX in gnucap-conf (trouble with mixing compilers).
   * enable link time optimization explicitly (Closes: #1015418).
   * use manpages provided by upstream.
   * remove obsolete patch against runall. File is gone.
