[mpich-discuss] Problem with mpich in debian bookworm

[Andrea Buzzi]

Hi,

I have an issue with mpich.
I have been using mpich with no problem so far, installed as standard package
in debian 11 on my 12-core PC.
I found mpich superior to intel mpi.

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' -------
I assume some library or dependency is missing, or maybe the new debian
package is broken.
I am asking your support since I could not find help online.

Best regards
