so heres the make file:

CC=gcc
default: msb doc
lib: libmsb-*
    cd libmsb-*/ && make -f Makefile.in
msb: lib msb.c
    $(CC) msb.c -o msb -I libmsb-*/ -L libmsb-*/ -l msb
install: msb
    install -s msb -t $(DESTDIR)/bin/
doc: msb.1
    groff -Tlatin1 -man msb.1 | col -b > msb.1.txt
cleanup:
    rm -f libmsb-*/*.o libmsb-*/*.a
clean: cleanup
    rm -f msb
    rm -f msb.1.txt

heres the error that i receive when running $make:

cd libmsb-*/ && make -f Makefile.in

Heres the Makefile.IN:

                      msb_std.c msb_encode.c msb_decode.c msb_7811.c
    $(CC) -c msb_std.c -o msb_std.o
    $(CC) -c msb_encode.c -o msb_encode.o
    $(CC) -c msb_decode.c -o msb_decode.o
    $(CC) -c msb_7811.c -o msb_7811.o
    ar crs libmsb.a msb_std.o msb_encode.o msb_decode.o msb_7811.o

the source code can be found here of the other files: https://sourceforge.net/projects/msb.berlios/files/latest/download

im still new to make files so any help is greatly appreciated....
