What's Wrong?

When I run Claude-code on RISC-V / ubuntu 24.04 I now and then get this error:
"This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). The promise rejected with the reason:
Error: Unsupported architecture: riscv64"

So somehow there is something crashing Claude a bit now and then - and sometimes (not often) I even get segmentation fault.

Have Claude-code been tested on RISC-V?

What Should Happen?

Claude should not have problems on RISC-V architecture (riscv64)

This is riscv64 not arm64! We need proper RISC-V support!

Hi @joakimeriksson - we don't currently have proper RISC-V support. From looking at your /doctor output, here are a few ideas that may improve your experience:

The "Error: Unsupported architecture: riscv64" is due to an issue with the auto-updater. Can you try updating to the latest Claude Code to see if this has been resolved? Otherwise, you may need to disable auto-updates via DISABLE_AUTOUPDATER=1 (can define in settings.json) while we fix this.
Search tool depends on ripgrep, which doesn't officially support RISC-V - though it looks to be in progress https://github.com/BurntSushi/ripgrep/pull/3165 (see latest comment). If you're able to get a working ripgrep build on your machine, you can set USE_BUILTIN_RIPGREP=0 to use it.
Please share any details around crashes.

@ant-kurt is riscv64 support in roadmap? that shouldn't be hard

joakimeriksson · 9 months ago

I totally agree on that - It is just about compiling on RISC-V and testing it. It almost works already - but not fully, without minor issues and warnings now and then.

If this requires RISC-V (hardware) CI, we can provide that.
