Hi,

I want to test a 'hello' module program (see below) in N900. I make it work in Ubuntu X86. But when I do the same thing in scratchbox
(sbox-FREMANTLE_ARMEL), the compilation result seems wrong.


I run command:
[sbox-FREMANTLE_ARMEL: ~/MyDocs/LinuxDriver] > fakeroot make -C ../linux-headers-2.6.32-23-generic/ M=$(pwd) modules


But the result:
make: Entering directory `/home/maemo/MyDocs/linux-headers-2.6.32-23-generic'
make: *** No rule to make target `modules'. Stop.
make: Leaving directory `/home/maemo/MyDocs/linux-headers-2.6.32-23-generic'


Note:
(1) I copy all the header files to the directory '/home/maemo/MyDocs/linux-headers-2.6.32-23-generic' already.

(2) I put 'hello.c' and 'Makefile' below into scratchbox directory '~/MyDocs/LinuxDriver'


Can anyone tell me what's wrong with it?
Thanks!

int text_init(void){

return 0;

module_init(text_init);

apt-get install kernel-headers then make -C /usr/src/kernel-headers M=$(pwd) modules

I compiled the code according to your hint and the module works normally on my N900 now. Thank you for your help!
