Package: src:glibc Version: 2.30-8 Severity: important Tags: sid bullseye 2.30-2 removed the installation of finclude/math-vector-fortran.h, which leads to build errors like reported in https://launchpad.net/bugs/1879092
glibc (2.30-2) unstable; urgency=medium * debian/rules.d/build.mk: do not install <finclude/math-vector-fortran.h> for now as it is not multiarch safe. Forwarded the discussion to https://gcc.gnu.org/pipermail/gcc/2020-June/232779.html It looks like the current x86 variant of this file is conditionalized and installable on any architecture. So instead of dropping the file, just install the x86 variant on every architecture.
