Package: g++-9 Version: 9.2.1-21 I have a package which fails to build on both Debian armel and mipsel with this g++ package, and with the same error: /usr/bin/ld: ./.libs/libfplll.so: undefined reference to `__atomic_store_8' /usr/bin/ld: ./.libs/libfplll.so: undefined reference to `__atomic_load_8'
which point to a missing -latomic somewhere. Since all other arches compiled nicely, I think the package is correct and the compiler makes something wrong in those cases, but I might err. Cheers, JP PS: here are links to both complete build logs: https://buildd.debian.org/status/fetch.php?pkg=fplll&arch=armel&ver=5.3.1-1&stamp=1577140525&raw=0 https://buildd.debian.org/status/fetch.php?pkg=fplll&arch=mipsel&ver=5.3.1-1&stamp=1577140414&raw=0
