Hello
I am using Scratchbox environment for cross compling
for TS-7250.
I 'maked' your project after making all the relevant
changes in the Makefile
But still I got the following errors.
/scratchbox/compilers/arm-gcc-3.3.4-glibc-2.3.2/arm-linux/sys-include/linux/mm.h:349:
error: `PAGE_OFFSET' undeclared (first use in this
function)

Since the errors are directly in your code. I thought
better to ask u instead of debugging myself.
Kindly look in the matter and reply soon.
Thank You
