Need help with makefile for multiple source files

[Randall Mackie]

Hi Xiaoyin,

I'm not sure what I do is the most elegant, but it works well for me.
First, I use a program called makedepf90, which you can find here:

http://personal.inet.fi/private/erikedelmann/makedepf90/

This program was designed for f90 and modules and it creates the
dependency list you need to compile f90 programs. It puts this
in a .depend file.

Then, my makefile is simple:


==============================================================================
# Include the dependency-list created by makedepf90 below

include .depend


CFLAGS         =
FFLAGS         =
CPPFLAGS         =
FPPFLAGS         =

include ${PETSC_DIR}/conf/base

csemfwd: ${FOBJ}  chkopts
	-${FLINKER} -o csemfwd ${FOBJ} ${PETSC_FORTRAN_LIB} ${PETSC_KSP_LIB}


depend .depend:
	makedepf90 -o DO_NOT_COMPILE *.f *.F > .depend

==============================================================================


Of course, you can modify this to suit your own needs.


Good luck,

Randy M.
