undefined reference to

[Waad Subber]

Hello everyone

I am calling a subroutine from my main program, and when I compile the code I get an error message  (undefined reference to 'mvec_') referring to the call statement in the main program. I have defined the subroutine as external in the main program using (external mvec), but the problem still unsolved ..! 

The makefile looks like:

OBJS= mvec.o
CFLAGS        = 
FFLAGS        = 
CPPFLAGS        =
FPPFLAGS        =


include ${PETSC_DIR}/bmake/common/base

all: $(OBJS)

mvec.o: mvec.F
    mpif90 -c mvec.F

exe: pro.o $(OBJS) 
    -${FLINKER} -o exe pro.o $(OBJS)  ${PETSC_LIB}
     ${RM} -f pro.o

include ${PETSC_DIR}/bmake/common/test

Can any one help me with this issue please ...!

Thanks

Waad
