Bug#925743: libgadu: ftbfs with GCC-9
Package: src:libgadu
Version: 1:1.12.2-3
Severity: normal
Tags: sid bullseye
User: debian-gcc@lists.debian.org
Usertags: ftbfs-gcc-9
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-9/g++-9, but succeeds to build with gcc-8/g++-8. The
severity of this report will be raised before the bullseye release,
so nothing has to be done for the buster release.
The full build log can be found at:
http://people.debian.org/~doko/logs/gcc9-20190321/libgadu_1.12.2-3_unstable_gcc9.log
The last lines of the build log are at the end of this report.
To build with GCC 9, either set CC=gcc-9 CXX=g++-9 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-9/porting_to.html
GCC 9 also passes the linker option --as-needed by default; typical
build issues are passing libraries before object files to the linker,
or underlinking of convenience libraries built from the same source.
