Bug#1042412: libmpich-dev: parallel gfortran prog fails with error

[Andrea Buzzi]

Package: libmpich-dev
Version: 4.0.2-3+b1
Severity: important
X-Debbugs-Cc: a.buzzi at isac.cnr.it

After I have recently upgraded to debian 12 (bookworm), trying to call mpich
with the script mpif90, I
get a long series of errors (both with gfortran and ifort - in the latter case
with FC="ifort"), basically
a multiplication of the following sequence:
------
/usr/bin/ld: /usr/lib/x86_64-linux-gnu/libmpich.a(lib_libmpich_la-pready.o):
in function `PMPI_Pready':
(.text+0x7b3): undefined reference to `ucp_am_send_nb'
/usr/bin/ld: (.text+0x7e7): undefined reference to `ucp_request_release'
/usr/bin/ld: (.text+0xb68): undefined reference to `ucs_status_string'
