Indeed even if you were to build it successfully - you will run into ABI issues - 2.6.35 is ABI v1 and we are currently at v3 (which is going to change soon even further to v4 - for ARC HS processors) More details at: https://github.com/foss-for-synopsys-dwc-arc-processors/linux/wiki/ARC-Linux-Syscall-ABI-Compatibility > 2) Is uclibc-ng 1.0.17 supposed to be compatible with 2.6.x kernel headers? No - modern/upstream uClibc-ng is not compatible with 2.6.35 You need to use the uClibc of the time - with pairing gcc/binutils - although that will be a can of worms > Any help is greatly appreciated. Thanks. Sorry - can't help you much here ! -Vineet
