Attaching a minimal sample makefile. The additional info it would
need is PETSC_DIR, PETSC_ARCH values for your install of PETSc.

All example/tests,tutorial dirs have makefiles in petsc format..

Great thanks, it seems that -lpetsc alone works .

I will follow this advice regarding the makefile, for the reason you gave.

Where should I get a typical makefile to modify please ?

Make sure your compiles have all the flags listed here..

Its best to use petsc makefile formats so that this info is

automatically picked up from the petsc config files. [and not tweak

user makefiles for every install of petsc..]

You are right.

Here is what I got

timac> make getincludedirs getlinklibs

-I/Data/Poub1/petsc-3.1-p5/macx/include -I/Data/Poub1/petsc-3.1-p5/include -I/Data/Poub1/petsc-3.1-p5/macx/include

What does it mean please for me to change in my makefiles ?

Do you mean that I should remove any link other than -lpetsc ?

Great thanks

Looks like you are not using PETSc makefiles - and upgrading from

older release to petsc-3.1

Currently there is only one library for petsc [-lpetsc]

Check:

cd $PETSC_DIR

make getincludedirs getlinklibs

Many thanks. This is solved.

Now at link I have the library not found. Any idea ?

-L/usr/local/petsc/macx/lib -lpetscsnes -lpetscvec -lpetscmat -lpetsccontrib -lpetscts -lpetscdm -lpetscksp -lpetsc -lmpich -lpmpich -lfmpich -lmpichf90 -lparmetis -lmetis -lfblas -lflapack

ld: library not found for -lpetscsnes

Looks like this is related to the following:

http://www.mcs.anl.gov/petsc/petsc-as/documentation/changes/31.html

# petsc.h and petscdef.h are replaced with petscsys.h and petscsysdef.h; while petsc.h now includes ALL PETSc include files.

Try removing all includes other than 'petsc.h' from your code.
