I'm developing on a X86_64 machine runningUbuntu-12.04 (which, AFAIK, doesn't have aarch64 toolchain) . I'm trying to find a cross-compilation tool-chain for building Linux kernel and applications targeting a qemu-aarch64 machine-emulation running Ubuntu 14.10. The closest thing I could find was the linaro-tool chain. I know this may not be pertinent here, but if you have any suggestions or pointers for a pertinent toolchain I will highly appreciate it. Thanks, Aravind
