Thanks for replying. Yes, at that time, it was sparc and this time it's aarch64. I'm building the kernel on x86_64 machine. So target is aarch64, host is x86_64. My question is about the end part (elf or linux). To build linux kernel, shouldn't it be elf? (using libraries for baremetal, like newlib) And to build a application that'll run on linux, shouldn't it be linux?(using libraries for linux) Please see that last part of https://wiki.osdev.org/Target_Triplet. I wonder why the toolchain name that I built linux kernel ends with -linux.
