I've installed rtlinux 3.0 on a 2.2.18 (slackware) kernel. I was able to
write and run a program that create periodic thread and write to a rtl
fifo. My next step was to break up the source into muliple files:
lp_mod.c - module load/cleanup
lp_main.c - start of new thread
myrt_io.c - some support function.
The created the following makefile:
RTINCLUDE = -I/usr/src/rtlinux/linux/include -I/usr/src/rtlinux-3.0/include
-I/usr/src/rtlinux-3.0/include/compat -I/usr/src/rtlinux-3.0/include/posix
INCLUDE = $(RTINCLUDE) -I../include
CFLAGS = -D__KERNEL__ -Wall -Wstrict-prototypes -fno-strict-aliasing -D__SMP__
-pipe -fno-strength-reduce -m486 -malign-loops=2 -malign-jumps=2
-malign-functions=2 -DCPU=686 -g -D__RTL__ -D_LOOSE_KERNEL_NAMES
-O2 $(INCLUDE)
CC = gcc
all: lp.o
lp.o: lp_mod.o lp_main.o mrt_io.o
ld -r -o lp.o lp_mod.o lp_main.o mrt_io.o
lp_mod.o: lp_mod.c
$(CC) $(CFLAGS) -DMODULE -c lp_mod.c
lp_main.o: lp_main.c
$(CC) $(CFLAGS) -c lp_main.c
mrt_io.o: mrt_io.c
$(CC) $(CFLAGS) -c mrt_io.c
clean:
rm -f *.o
The problem? I can't create a good loadable module? Either I am
missing module information, can find stuff like stdio, can't compile due
to multiple define in system header...very frustrating. I'm not a makefile
expert, but have been doing C / Linux program for a number of years.
Any advice on make, order of #includes<>, etc, is appreciated..
