We don't provide a binary for riscv64 currently. I've changed this from a bug report to an enhancement request.

Ok! I managed to build one - works fine - so should not be a problem.

@joakimeriksson upstream it?

@etraut-openai why not you just have to order a few machine of #RISCV and take @joakimeriksson upstream patches, there will be 10K people using very powerful RISCV laptops with ubuntu 26.04 next year in 2026 as Deepcomputing 100 universities/AI startups/ Community Projects support programmes announded in RISCV Summit NA

https://deepcomputing.io/deepcomputing-at-risc-v-summit-na-2025-empowering-the-future-of-open-ai-computing/,

hope you wont get 10K issues raised and swarmed on github.

Many thanks in advance.

Thanks for the suggestion. Please upvote this issue if you want to see this. We use upvotes / reactions to inform priorities for enhancement requests.

@etraut-openai how do we do upvotes please? @joakimeriksson do you know how? Codex definitely can be one of our AI open source project in our #RISCV hardware support program

So these were the few changes that I needed to do to get it building on riscv64.

(in codex-rs - do cargo build).
