Thanks in advance.

I'm having trouble compiling my custom device driver. I'm using the 14.1 tools.

My compiled linux is in /home/user1/linux-socfpga

My cross compiler is in /home/user1/gcc-linaro-arm-linux-gnueabihf-4.8-2013.12_linux/bin/arm-linux-gnueabihf-

My device driver is in /home/user1/newDriver

I'VE TRIED LOTS OF THINGS - and googled for a few hours

One was -- from the newDriver directory I tried:

# ] make ARCH=arm CROSS_COMPILE=/home/user1/gcc-linaro-arm-linux-gnueabihf-4.8-2013.12_linux/bin/arm-linux-gnueabihf- KERNEL_SRC=/home/user1/linux-socfpga

IT TRIES BUT CAN'T FIND the kernel header files.

Any help would be greatly appreicated.
