Hi all,
I'm using an ARM Cortex-A9. There is Linux Debian 4.6.2-11 distribution which I installed following this instruction http://wiki.debian.org/InstallingDebianOn/TI/BeagleBone. I faced a problem during compilation a simple Hello-World kernel module:
root@localhost:~/test/KernelModuleTest# make -C /usr/src/linux-headers-3.1.0.paullliu-1-am335x/ SUBDIRS=$PWD modules
make: Entering directory `/usr/src/linux-headers-3.1.0.paulliu-1-am335x'
make: Warning: File `/usr/src/linux-headers-3.1.0.paulliu-1-am335x/arch/arm/Makefile' has modification time 3.8e+08 s in the future
make[1]: Warning: File `scripts/Makefile.lib' has modification time 3.8e+08 s in the future

make: Leaving directory `/usr/src/linux-headers-3.1.0.paulliu-1-am335x'
More precisely, I havn't got this dir /usr/src/linux-headers-3.1.0.paulliu-1-am335x/include/mach and thus, no
headers there.
I have followed by the debian installation manual very strictly and installed all packages for sure. In fact, now I have /usr/src/linux-headers-3.1.0.paulliu-1-am335x/arch/arm/include/asm/mach, but there are no memory.h. At the same time, I have memory.h in this dir : /usr/src/linux-headers-3.1.0.paulliu-1-am335x/arch/arm/include/asm/.
Just copying this file didn't rescued and caused another errors.
Which way is the simplest to resolve this problem? or How can I install missing packages and not to break anything?
I will appreciate any help on this.
