Building embedded Linux for the Terasic DE10-Nano

Hi,

I am using the following link:
Building embedded Linux for the Terasic DE10-Nano (and other Cyclone V SoC FPGAs) | bitlog.it

In step 3.1, gcc-linaro-6.3.1-2017.05-x86_64_arm-linux-gnueabihf is not available in Linaro site.

So i went with gcc-linaro-6.4.1-2017.11-x86_64_arm-linux-gnueabihf.

In step 6.2, rel_socfpga-4.11_17.08.02_pr is not available. I am trying to use rel_socfpga-4.10_17.05.01.

I have successfully completed until step 5,

But i am unable to compile linux kernel, ending up with makefile errors.
Is this a compatibility issue between the versions of compiler, uboot and linux kernel.
What version of linux kernel to be used for proper compatibility?
