Reading other topics about LTIB, I found one that some people did a module driver using LTIB under shell mode:
./ltib -m shell
and apparently, this is a easy way to compile a module driver:
makefile:
obj-m := test.o
The fact is, using the hello.c, standard module driver "hello world", if I do a simple command:
LTIB> make
it complains:
make -C /home/serkam/ltib-imx31vip2704-R13/rpm/BUILD/linux/ M=/home/serkam/ltib-imx31vip2704-R13/rpm/BUILD/linux-2.6.24/drivers/hello_driver

The question is:
1) Using LTIB shell mode, how can I define __LINUX_ARM_ARCH__ ?
2) Someone could get a module driver compiled under LTIB shell mode?
Any help will welcome
