Re: [Devil-Linux-discuss] Making bootcd.iso

[Bradlee L. <bra...@gm...>]

I tried to run it, and it worked fine, but my program did not work.
What's the easiest way to compile the driver against the kernel? I
really don't want to go through the build process. If I sent someone
the .tar.gz file, could you return me a compiled module (lcm.o) that I
could use?

If it helps, here's the makefile sent with the driver:
------Makefile------
#
# Makefile for LCD driver and testprograms
#
CC = gcc
#
# Uncomment the correct line for your kernel-version!
#
#KERNEL = -DKERNEL20
KERNEL = -DKERNEL21

INSTALLDIR = /lib/modules/`uname -r`/misc/

#
# If you want some debugging output then add -DDEBUG to the CFLAGS
# Attention: This will fill your syslog quite fast!
#
CFLAGS  =       $(KERNEL) -D__KERNEL__ -I/usr/src/linux-2.4/include -Wall \
               -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe \
               -ffixed-8 -DMODULE -DMODVERSIONS -finline-functions \
               -include /usr/src/linux-2.4/include/linux/modversions.h \
# -DLCM_DEBUG
LDLAGS = -O2 -Wall -I/usr/src/linux-2.4/include -Wstrict-prototypes \
-D__KERNEL__ -DMODULE -Xlinker \
-include /usr/src/linux-2.4/include/linux/modversions.h

OBJS = lcd_module.o lcd.o

lcm.o: lcm_module.c lcm_module.h lcm.h
$(CC) $(CFLAGS) -c lcm_module.c -o lcm.o

.PHONY: install clean

install:
[ -d $(INSTALLDIR) ] || mkdir -p $(INSTALLDIR)
install -c -m644 lcm.o $(INSTALLDIR)
clean:
rm -f *.o
