building libraries

[Satish Balay]

Did you try PETSc examples before attempting your code? Do they work?

Looks like you are not using PETSc makefiles. This is the recommended
thing to do.

If you want to have your own makefiles - do the following - and make
sure all the comile options you see are listed in your makefile.

cd src/ksp/ksp/examples
make ex2

You can also get this info with the following [in PETSC_DIR]:

make getpetscflags
make getincludedirs
make getlinklibs
