Hi Chew,

I'm a newbie in linux/android and Im having some problems to compile the my
module.
i dowloaded the android-goldfish-2.6.29 snapshot and the android plataform.
Compiled the kernel with your instructions to ARCH and CROSS_COMPILE and
have no problem, but when i try to compile the module it givesthe error:
- entering directory /home/acker/goldfish/kernel
- no rule to process the target "modules"

any idea of what  i did wrong?

thanks for the help,
Eduardo Acker
