Add support for RISC-V #1182

advancedwebdeveloper · 2021-01-27T21:41:20Z

Hi.

Looks like there is no support for RISC-V arch.

I was trying to build https://github.com/pravega/pravega-client-rust .
CC @Tristan1900 @zwx14700 @shrids .

Here is what I tried:

$ export RUST_BACKTRACE=1
$ cargo test
Compiling ring v0.16.19
Compiling openssl-sys v0.9.60
Compiling http-body v0.3.1
Compiling http-body v0.4.0
error: failed to run custom build command for ring v0.16.19

Caused by:

This will probably be fixed by #1174.

It does not explain how to contribute into RISC-V port and how (at least) to allow the compilation of the crate.

It does not explain how to contribute into RISC-V port and how (at least) to allow the compilation of the crate.

The work we're doing to enable all the features on wasm32, MIPS, etc. will enable ring to work on RISC-V. Then we can add CI/CD jobs that verify ring builds for RISC-V. Ideally we'd also have optimized assembly for RISC-V too, eventually.

bernardoaraujor · 2021-08-02T17:36:00Z

I'm also looking forward to RISC-V support!
Can we expect that for v0.17.0?

Check out PR #1436 which contains the changes to base.h that are needed after #1558.

enh-google · 2023-02-25T02:26:14Z

fwiw, we're using those changes in Android (https://android-review.googlesource.com/c/platform/external/rust/crates/ring/+/2408495/4)...

tommythorn · 2023-03-02T03:38:42Z

Note, this is regressing https://github.com/nextest-rs/nextest which worked on RISC-V before they pulled in ring :(

ifsheldon · 2023-04-09T16:54:23Z

do we have any updates? I see there are a few PRs trying to resolve this but they are all pending.

kush930 · 2023-06-02T11:55:32Z

It does not explain how to contribute into RISC-V port and how (at least) to allow the compilation of the crate.

The work we're doing to enable all the features on wasm32, MIPS, etc. will enable ring to work on RISC-V. Then we can add CI/CD jobs that verify ring builds for RISC-V. Ideally we'd also have optimized assembly for RISC-V too, eventually.

Hi briansmith,

I am not able to build ring v0.16.20 on riscv64 platform, i added line from link-light4@4d5dde5#diff-a746f36ad550c7ba0b9d8557d26374079a51cccec2555a5e023129e32af6b789

After changing in source code from above link, i am not able to build successfully, can you look on output-

Remove cert generation and revert back from ring -> sha2 briansmith/ring#1182

warp cannot be built on riscv64 in the near future as it is rust and its crate 'ring' does not support RISC-V: briansmith/ring#1182 Reported-by: Ivan A. Melnikov <iv at altlinux.org>

briansmith · 2023-10-02T03:08:29Z

It works now. Because RISC-V doesn't have carry/borrow flags, the math probably is far from optimal. But it builds as of PR #1627.
