It is not really obvious to me what Chandu is trying to say above,
so I will outline what *I* do to make an rtl module from multiple source
files. By way of example, I'll include a small Makefile which I will
liberally comment for your viewing pleasure.
----- Begin Makefile -----
#
# This is a list of object files to be used to generate the module.
#
OBJECTS = main.o front_panel.o net_process.o
#
# Specify the libraries required. I almost always need libm. The libgcc is
to provide the 64 bit
# integer routines like idiv3. Note this mechanism finds it automatically
assuming gcc is on your
# path. If gcc is not on your path, you will have bigger problems than not
finding idiv3...
#
LIBPATHS= -L/usr/lib
LIBGCC := $(shell $(CC) -print-libgcc-file-name)
LIBS = -lm
#
# The main target - lists everything to be built - one module in this case.
#
# In my case, I also have it synch the filesystem and remove the old module
so that I am ready to
# insert the new module. The sync;sync;sync is to make rebooting easier
when my module crashes the
# system.
#
all: testprog.o
sync; sync; sync
-rmmod testprog
#
# The following line actually builds the output module. The -r on the ld
command line says to build
# an output .o file without resolving all of the symbols. Any unresolved
symbols will be flagged at
# module load time.
#
testprog.o: $(OBJECTS)
$(LD) -r -o acu.o $(OBJECTS) $(LIBPATHS) -static $(LIBS) $(LIBGCC)
#
# The following are the dependencies for the individual object files. The
flags defined in the
# rtl.mak file will take care of compiling these properly.
#
main.o: main.c main.h
front_panel.o: front_panel.c front_panel.h net_process.h main.h
net_process.o: net_process.c net_process.h main.h
#
# Finally, I include the rtl.mk file to get all the build rules used by
RTLinux into my Makefile. This
# is by far the easiest way to make sure that you have all the correct
definitions on your various
# command lines.
#
include /usr/include/rtlinux/rtl.mk
----- End Included Makefile -----
I hope this has been helpful for the original requestor. Perhaps
this type of information should be added to a FAQ?
Regards,
Steve Cohen
