Source: deal.ii
Version: 9.5.1-2
Severity: normal

I'm getting an error running deal.ii tests building against petsc 3.20
(from experimental)

Likewise undefined __gmpn_com with quick_tests/affinity.release,
quick_tests/step.release.  All 25 tests fail with either undefined
__gmpn_neg or __gmpn_com.


__gmp* is provided by libgmp, which suggests build configuration for
gmp is not getting through, not setting -lgmp for linking.

deal.ii recently built successfully in unstable (for time_t), so it's
not time to mark this bug severity: serious.  I get it when trying to
rebuild against petsc 3.20 from experimental. But it's not obvious to
me that petsc 3.20 itself would be triggering the problem.  Perhaps
it's a local issue on my system with the experimental petsc builds
that might resolve itself after we upload petsc 3.20 to unstable,
which I've requested in transition Bug#1067064.

Filing this bug to keep track, or see if anyone else is experiencing
the same problem.
