[Debian-med-packaging] Bug#777791: ball: ftbfs with GCC-5

[Matthias Klose]

Package: src:ball
Version: 1.4.2+20140406-1
Severity: normal
Tags: sid stretch
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-5

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-5/g++-5, but succeeds to build with gcc-4.9/g++-4.9. The
severity of this report may be raised before the stretch release.

The full build log can be found at:
http://people.debian.org/~doko/logs/gcc5-20150205/ball_1.4.2+20140406-1_unstable_gcc5.log
The last lines of the build log are at the end of this report.

To build with GCC 5, either set CC=gcc-5 CXX=g++-5 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

  apt-get -t experimental install g++ 

Common build failures are C11 as the default C mode, 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-5/porting_to.html
