Hi,

I experienced a failure in recompiling redistributeMeshPar. I already cheched my ./Allwmake, as suggested in a previous message, but this is not the problem.

Compilation of redistributeMeshPar failed due to an unresolved reference.

The failure occured with the following:
Ubuntu 7.10
OF 1.4.1
HP nw8440
gcc version 4.1.3

~/OpenFOAM/OpenFOAM-1.4.1/applications/utilities/parallelProcessing/redistribute MeshPar$ wmake

It seems that the problem is due to `METIS_mCPartGraphRecursive2' in particular.

Thank you in advance,
Pietro

ParMetis seems to come with its own version of the Metis library which overwrites the Metis library from Metis-5.0.

Rebuild the one that comes with the ParMetis. Try something like

cd decompositionMethods/parMetisDecomp
rmoall
./Allwmake

If this doesn't help do the opposite: build the metis-5.0 one last.

Hi Mattijs,

thank you for your suggestions. Actually I fixed the problem. I was trying to use a different version of gcc. Instead I tried again using the version included in the OF 1.4.1 package and in the architecture folder and it worked.

Thank you,
Pietro
