Package: src:ploop Version: 1.15-7 Severity: normal Tags: sid bullseye User: debian-...@lists.debian.org Usertags: ftbfs-gcc-10
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-10/g++-10, but succeeds to build with gcc-9/g++-9. 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/gcc10-20200225/ploop_1.15-7_unstable_gcc10.log The last lines of the build log are at the end of this report. To build with GCC 10, either set CC=gcc-10 CXX=g++-10 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-10/porting_to.html [...] make[2]: Entering directory '/<<PKGBUILDDIR>>' make[3]: Entering directory
