Error load of MUMPS with debian 12 (bookworm)

FreeFEM installation
1

Hello,

I recently upgraded my debian os from version 11 to 12. I was using the debian FreeFem package and the MUMPS library without any issue on debian 11.

With debian 12, an error is raised when loading the MUMPS library load "MUMPS":

-- FreeFem++ v4.11 (Mon Jul 10 11:56:47 AM CEST 2023 - git v4.11)
   file : 2DLISSurfactantsFEMIC.edp
 Load: lg_fem lg_mesh lg_mesh3 eigenvalue 

Load error: MUMPS
	 fail: 
 dlerror : libdmumps_seq-5.3.so: cannot open shared object file: No such file or directory
list prefix: './' '/scratch/rvallon/FreeFEM/lib/ff++/4.11/lib/' list suffix: '' , '.so' 
  current line = 31
Load error : MUMPS
	line number :31, MUMPS
error Load error : MUMPS
	line number :31, MUMPS
 code = 2 mpirank: 0

When loading MUMPS, libdmumps version 5.3 is looked for. debian 12 has libdmumps version 5.5 by default.

Is there any way to indicate which version to load?

Best,

Ok, this could be solved by

  1. installing the debian package libfreefem++
  2. updating /etc/freefem++.pref

However, an other error is raised when including getARGV.idp include "getARGV.idp":

-- FreeFem++ v4.9 ( - git no git)
 Load: lg_fem lg_mesh lg_mesh3 eigenvalue 
init MUMPS_SEQ: MPI_Init
 Add lapack interface ... load: iovtk

  -- try  :"/usr/lib/ff++/4.9/idp/getARGV.idp"

This was solved by properly editing /etc/.freefem++.pref

loadpath += "./"
loadpath += "/usr/include/freefem++/lib"
includepath += "/usr/include/freefem++/idp"
