Hi, I confirm a problem in upgrading mpich from debian bullseye to bookworm.
In fact is also appeared on another independent system I upgraded. It seems to me (though, since I did many attempts I am not 100% sure) that it is due to errors in the wrapper and binary files installed in /usr/bin (eg. mpifort etc.). In fact, at once I found installed the openmpi wrapper files (all binary files, coming from the package openmpi-bin) instead of the corresponding mpich files (text files). This in spite of the fact that I never tried to install openmpi. I do not know if openmpi-bin was required by some other package. Apparently, I resolved with the following: uninstalled openmpi-bin reinstalled mpich This worked! -- Andrea Buzzi Associate senior scientist Istituto di Scienze dell'Atmosfera e del Clima - CNR-ISAC Institute of Atmospheric Sciences and Climate - CNR-ISAC Via Gobetti 101, I-40129 Bologna email: [email protected]
