Hi,

thank's for the answer.

A Divendres 14 Novembre 2003 14:35, Benjamin S. Kirk va escriure:

See the attach file.

Yes there's a dependencies. Also, there are a change betwend the version 2.1.3 
(woody-stable) and 2.1.6 (sarge-testing). The last one needs the mpich 
library (version  mpich (>= 1.2.5-4)).

In this file, the lines that you are talking about are:

# For mpich:
ifeq ($(PETSC_MPI),mpich)
  MPI_HOME       = /usr/lib/mpich
  MPI_LIB        = -L${MPI_HOME}/lib/shared -L${MPI_HOME}/lib -lmpich
  MPIRUN         = /usr/bin/mpirun.mpich
  MPI_INCLUDE    = -I/usr/lib/mpich/include
endif

So, I have the error. But, if I add -lmpe I have this:

`/rhome/lepalom/test_finite/libmesh-0.4.1-rc2/examples'

So only there are one error. This could be a bug in the petsc package, so 
please confirm that you didn't have this and I will comment it to the debian 
package mantainer.

Now, we have only the error on this part of code.
