Hi all,
I'm trying to compile comedi on 2.6-test2. The very naive way (with
configure) does not work (as expected). However, comedi conforms
(mainly) to the kernel makefile convention. So I tried this:
make -C /usr/src/linux-2.6.0-test2
SUBDIRS=/home/bp1/c/usb/2.6/comedi/comedi/ V=1
make -f scripts/Makefile.build
obj=/home/bp1/c/usb/2.6/comedi/comedi//drivers
scripts/Makefile.build:27: kbuild:
/home/bp1/c/usb/2.6/comedi/comedi//drivers/Makefile - Usage of
export-objs is obsolete in 2.5. Please fix!
make -f scripts/Makefile.build
obj=/home/bp1/c/usb/2.6/comedi/comedi//kcomedilib
scripts/Makefile.build:27: kbuild:
/home/bp1/c/usb/2.6/comedi/comedi//kcomedilib/Makefile - Usage of
export-objs is obsolete in 2.5. Please fix!
make -f scripts/Makefile.build obj=arch/i386/boot arch/i386/boot/bzImage
make -f scripts/Makefile.build obj=arch/i386/boot/compressed \
IMAGE_OFFSET=0x100000
arch/i386/boot/compressed/
vmlinux
Kernel: arch/i386/boot/bzImage is ready
Building modules, stage 2.
make -rR -f scripts/Makefile.modpost
scripts/modpost vmlinux drivers/net/pcmcia/3c574_cs.o
drivers/net/pcmcia/3c589
_cs.o drivers/net/8139cp.o drivers/net/8139too.o drivers/net/8390.o
drivers/char
/agp/agpgart.o drivers/net/wireless/airo.o
drivers/net/wireless/airo_cs.o driver
s/net/wireless/arlan-proc.o drivers/net/wireless/arlan.o
drivers/net/wireless/at
mel.o drivers/net/wireless/atmel_cs.o drivers/usb/class/audio.o
drivers/net/pcmc
Looks like as if the kernel itself has been compiled and not comedi.
In comparison: kernel 2.4.x makes it (nearly) right:
make -C /usr/src/linux SUBDIRS=/home/bp1/c/usb/2.6/comedi/comedi/
make: Entering directory `/usr/src/linux-2.4.21'
. scripts/mkversion > .tmpversion

Is it a kernel2.6 issue or is it a comedi issue? Actually the comedi
configuration is a hack and does not completely comply with the kernel
makefile conventions. Probably because it has to run on either 2.x.x
kernel. Who can help? Is the way to compile exernal modules from the
2.4.x kernel deprecated? Is there another (more elegant) way? Would be
nice to use as much as possible from the 2.6 stuff. Just now comdi does
most of the stuff by a "configure" by itself. This leads to another
problem where comedi is not able to obtain the compiler flags etc from
the 2-6 kernel. However, this is a hack and has to be chnanged anyway.
Therefore my questions: What is the best way to compile external modules?
What has changed from 2.4 to 2.6? I noticed that .htdepend is no longer
there and that there is no rules file.
