SubjectRe: compiling external kernel modules (comedi.org)
Sam,

how can I include the "legal way" includes for comedi? Just now comedi
has set up a "linux/include" path in its directory but I think this not
the elegant way and it also dosn't work right now.

snoopy:/home/bp1/c/usb/2.6/comedi/comedi# make -C
/usr/src/linux-2.6.0-test2 SUBDIRS=$PWD V=1 modules
make: Entering directory `/usr/src/linux-2.6.0-test2'
make -f scripts/Makefile.build obj=scripts
make -f scripts/Makefile.build obj=arch/i386/kernel
arch/i386/kernel/asm-offsets.s
make[1]: `arch/i386/kernel/asm-offsets.s' is up to date.
*** Warning: Overriding SUBDIRS on the command line can cause
*** inconsistencies
mkdir -p .tmp_versions
make -f scripts/Makefile.build obj=/home/bp1/c/usb/2.6/comedi/comedi
gcc -Wp,-MD,/home/bp1/c/usb/2.6/comedi/comedi/.comedi_fops.o.d
-D__KERNEL__ -Iinclude -Wall -Wstrict-prototypes -Wno-trigraphs -O2
-fno-strict-aliasing -fno-common -pipe -mpreferred-stack-boundary=2
-march=athlon -Iinclude/asm-i386/mach-default -nostdinc -iwithprefix
include -DMODULE -DKBUILD_BASENAME=comedi_fops
-DKBUILD_MODNAME=comedi_fops -c -o
/home/bp1/c/usb/2.6/comedi/comedi/comedi_fops.o
/home/bp1/c/usb/2.6/comedi/comedi/comedi_fops.c
/home/bp1/c/usb/2.6/comedi/comedi/comedi_fops.c:42:29:
linux/comedidev.h: No such file or directory

P.S.: I'm subscribed...
