link with other libraries

[Satish Balay]

The basic form of a PETSc makefile is as follows:

>>>>>>
CFLAGS           =
FFLAGS           =
CPPFLAGS         =
FPPFLAGS         =
CLEANFILES       =

include ${PETSC_DIR}/bmake/common/base

ex1: ex1.o  chkopts
        -${CLINKER} -o ex1 ex1.o  ${PETSC_KSP_LIB}
        ${RM} ex1.o
>>>>>>>>>>


If you wish to specify additonal libraries - you can do it as:


>>>>>>>
MY_INC          = -I/my/include
MY_LIB          = -L/my/lib -lmy

CFLAGS           =
FFLAGS           =
CPPFLAGS         = ${MY_INC}
FPPFLAGS         =
CLEANFILES       =

include ${PETSC_DIR}/bmake/common/base

ex1: ex1.o  chkopts
        -${CLINKER} -o ex1 ex1.o  ${MY_LIB} ${PETSC_KSP_LIB}
        ${RM} ex1.o
>>>>>>>>>

Also - you should make sure this library is compiled with the same
compilers as PETSc is compiled with.
