Either it does not see your makefile in that directory or something is
wrong with the makefile. The simplest makefile is

ex2: ex2.o
      ${CLINKER} -o ex2 ex2.o ${PETSC_LIB}

include ${PETSC_DIR}/${PETSC_ARCH}/conf/variables
include ${PETSC_DIR}/${PETSC_ARCH}/conf/rules

What most experimenters take for granted before they begin their
experiments is infinitely more interesting than any results to which their
