Package: src:measurement-kit
Version: 0.7.1-2
Severity: normal
Tags: sid buster
User: [email protected]
Usertags: ftbfs-gcc-8
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-8/g++-8, but succeeds to build with gcc-7/g++-7. The
severity of this report will be raised before the buster release.
The full build log can be found at:
http://aws-logs.debian.net/2018/05/01/gcc8/measurement-kit_0.7.1-2_unstable_gcc8.log.gz
The last lines of the build log are at the end of this report.
To build with GCC 8, either set CC=gcc-8 CXX=g++-8 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-8/porting_to.html
