[Android-tools-devel] Bug#1037574: android-platform-system-tools-hidl: ftbfs with GCC-13

[Matthias Klose]

Package: src:android-platform-system-tools-hidl
Version: 10.0.0+r36-3
Severity: normal
Tags: sid trixie
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-13

[This bug is targeted to the upcoming trixie release]

Please keep this issue open in the bug tracker for the package it
was filed for.  If a fix in another package is required, please
file a bug for the other package (or clone), and add a block in this
package. Please keep the issue open until the package can be built in
a follow-up test rebuild.

The package fails to build in a test rebuild on at least amd64 with
gcc-13/g++-13, but succeeds to build with gcc-12/g++-12. The
severity of this report will be raised before the trixie release.

The full build log can be found at:
http://qa-logs.debian.net/2023/05/22/logs/android-platform-system-tools-hidl_10.0.0+r36-3_unstable_gccexp.log
The last lines of the build log are at the end of this report.

To build with GCC 13, either set CC=gcc-13 CXX=g++-13 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

  apt-get -t=experimental install g++ 

Common build failures are new warnings resulting in build failures with
-Werror turned on, or new/dropped symbols in Debian symbols files.
For other C/C++ related build failures see the porting guide at
http://gcc.gnu.org/gcc-13/porting_to.html
