[Debian-med-packaging] Bug#1087552: nthash: FTBFS on arm64: undefined reference to `omp_get_num_threads'

[Emanuele Rocca]

Source: nthash
Version: 2.3.0+dfsg-1
Severity: serious
Justification: FTBFS
Tags: trixie sid ftbfs
User: debian-arm at lists.debian.org
Usertags: arm64

During a rebuild of all packages in sid, this package failed to build on
arm64. On amd64 it builds correctly.

Here is the error message:
