[petsc-users] make file issues

[Gideon Simpson]

I’ve been trying to use some code that was originally developed under petsc 3.6.x with my new 3.7.5 installation.  I’m having an issue in that the way the code is written, it’s spread across several .c files.  Here are the essential features of the makefile:

all: myprog1

OBJS = functions.o \
	utils.o

include ${PETSC_DIR}/lib/petsc/conf/variables 
include ${PETSC_DIR}/lib/petsc/conf/rules

myprog1: prog1.o ${OBJS}
	${CLINKER} -o myprog1 myprog1.o ${OBJS} ${PETSC_LIB}


make all  yields:

make: *** No rule to make target `myprog1.o', needed by `myprog1'.  Stop
