Package: singular Version: 4.0.2-p2+ds-3 Severity: important User: [email protected] Usertags: ftbfs-gcc-6 gcc-6-no-match
This package fails to build with GCC 6. GCC 6 has not been released yet, but it's expected that GCC 6 will become the default compiler for stretch. Note that only the first error is reported; there might be more. You can find a snapshot of GCC 6 in experimental. To build with GCC 6, you can set CC=gcc-6 CXX=g++-6 explicitly.
