metis 5.0 on BluegeneP

Hi,

I am trying to use metis 5.0 metis_partmeshdual function on a BluegeneP node.
The installation did not worked. I had to change the definition of the variable GKLib in CMakeList.txt:
set(GKLIB_PATH "$PATH_TO_METIS/GKlib")

I also had to add "-DCMAKE_CXX_COMPILER=xlc++_r" to CONFIG_FLAGS in the makefile to define the c++ compiler.
With these changes metis compiled on the bluegeneP and the POWER7.

The code (in Fortran) is working on the power7 and my machine (Linux PC) but not on the bluegeneP.

Here is the call to the function:
call METIS_PartMeshDual
& (nelem2, npoin2, eptr, eind, nulltable,
& nulltable, ncommonnodes, nparts, nulltable,
& nulltable, edgecut, epart, npart)
nulltable is an non allocated integer table.
I checked in metis code and it considered as NULL in C.
I checked the input tables which are ok.
I debugged with printf and ended in the function SetupCtrl of METIS_PartGraphKway.

The table are renumbered to fit a C numbering because using the option table
was not working and it is unfit for Fortran to define this table as we don't have access to the C macro to get the value of each parameter.

Do you have any ideas what is going wrong ?

I am at your disposal for any informations.
