Package: src:farmhash Version: 0~git20190513.0d859a8-1 Severity: normal Tags: sid bookworm User: [email protected] Usertags: ftbfs-gcc-11
[This bug is not targeted to the upcoming bullseye 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-11/g++-11, but succeeds to build with gcc-10/g++-10. The severity of this report will be raised before the bookworm release, so nothing has to be done for the bullseye release. The full build log can be found at: http://people.debian.org/~doko/logs/20210228/filtered/gcc11/farmhash_0~git20190513.0d859a8-1_unstable_gcc11.log The last lines of the build log are at the end of this report. To build with GCC 11, either set CC=gcc-11 CXX=g++-11 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-11/porting_to.html GCC 11 defaults to the GNU++17 standard. If your package installs header files in /usr/include, please don't work around C++17 issues by choosing a lower C++ standard for the package build, but fix these issues to build with the C++17 standard.
