TOOLCHAIN for target aarch64-unknown-linux-gnu

[shawn peng]

What TOOLCHAIN value should be used for target aarch64-unknown-linux-gnu in Makefile.common file? To cross compile Tock on Linux/x86-64bit.

The llvm is the current TOOLCHAIN value in Makefile.common, which failed the link process.

As I changed linker=lld to linker=aarch64-linux-gnu-ld, or to linker=aarch64-linux-gnu-gcc.

should I need change the linker-flavor=ld.lld too?

Thanks,

Shawn

Do you have a basic non-Tock example of cross-compiling Rust for your target platform? It should be the same toolchain.

The tool chain I used is "nightly-x86_64-unknown-linux-gnu", the link error may relate to ld.lld file or script, do you know where to find ld.lld?

Hi Shawn,

It's great that you're excited about using Tock on different architectures, but this list doesn't have anyone who's very familiar with the internals of compiling Rust to architectures other than the ones we've already tried ourselves.

A much better venue for questions like this would be the Rust users forum, or the Rust embedded working group. I believe there are folks over there who have actually compiled Rust to Cortex-A.

We're of course excited for you to keep us posted as you progress getting Tock up and running on a Cortex-A.

I see, I will update you when got it resolved.

Thanks,
