Hi,

Some years ago, I used to use = sparc-ab-elf- to build linux kernel.

I thought that tool was for = building bare-metal program. (because linux kernel is a kind of = bare-metal program itself)

We had also sparc-ab-linux- that = were used for compiling application that runs on = linux.

 

Recently, I found a website that I should use = aarch64-linux-gnu tool to build the kernel.

I tried following it and it = generated vmlinux file. (I can’t find the web page link, but = I’m sure I wrote that procedure down when I built = vmlinux)

Now I find it strange, because the tool name = ‘aarch64-linux-gnu-‘ seems to be the one for compiling = application on linux!

Am I missing something? Could anyone clarify what is wrong = with my idea?
