make hangs without even giving any error on 10.10

[Maurizio]

I am running the new Ubuntu 10.10
I've tried on two different computers to compile this module, either on a live cd, or on a clean installation, with and without the recent updates (kernel 2.6.35.22-35) but I am not able to even get any error when I try to compile this module. make command simply hangs and if I try with the debug output, it seems to hang when reading the makefile

ubuntu@ubuntu:/usr/src/modules/acerhk$ sudo make -d

Can you help me in working this out?

Thanks

I am Debian user, but I guess the problem is the same there. The "version.h" format seems to be changed, so the following line hangs in the Makefile.

KERNELVERSION=$(shell awk -F\" '/REL/ {print $$2}' $(shell grep -s -l REL $(KERNELSRC)/include/linux/version.h $(KERNELSRC)/include/linux/utsrelease.h))

Just edit Makefile you have in acerhk module and replace the line above by the following (use your kernel version instead):

KERNELVERSION=2.6.37

Make will work perfectly after that. Also, if possible, report the problem to "acerhk" developer so they can fix that. I do not have the time for that :)

It seems to be a partial duplicate of #555828

I have the exact same problem in 11.04.
This is a huge bug as far as I am concerned.
This also happens with compiling the acer_acpi package

Hi Ruslans, thank you for this hint.
This stops the hang indeed, unfortunately it gives other compile errors on 11.04:

ubuntu@ubuntu-WIM-2030:~/Downloads/acerhk-0.5.35$ make
make -C /lib/modules/`uname -r`/build SUBDIRS=/home/ubuntu/Downloads/acerhk-0.5.35 modules
make[1]: Entering directory `/usr/src/linux-headers-2.6.38-8-generic'
scripts/Makefile.build:49: *** CFLAGS was changed in "/home/ubuntu/Downloads/acerhk-0.5.35/Makefile". Fix it to use EXTRA_CFLAGS. Stop.
make[1]: *** [_module_/home/ubuntu/Downloads/acerhk-0.5.35] Error 2
make[1]: Leaving directory `/usr/src/linux-headers-2.6.38-8-generic'
make: *** [acerhk.ko] Error 2

I guess devs would have to fix that too in the repos, but there seems to be no maintainer.

There is a fix here:
https://bugs.launchpad.net/ubuntu/+source/acerhk/+bug/555828
for 11.04.

hope it will be incoporated in ubuntu's sources
