[petsc-users] make error from the ex1.c

[Satish Balay]

Can't flood petsc-users mailing list with huge configure.log. petsc-maint is
more apporpriate for such issues.

CFLAGS     = ${PETSC_CC_INCLUDES} 
FFLAGS     = ${PETSC_FC_INCLUDES}

ex1: ex1.o
        ${CLINKER} -o ex1 ex1.o ${PETSC_LIB}

<<<<<<<<

This makefile is incorrect for petsc-dev. Hence you get errors..

Try using the attached makefile. [check src/ksp/ksp/examples/tutorials/makefile]
