Rust Embedded ESP32C6 STD (Does Ring support the target "riscv32imac-esp-espidf" ?)
Hello,
I think I am missing a rustflag that is preventing the compiler to finish. If not could someone point myself in the right direction ?
config.toml

runner = "espflash flash --monitor" # Select this runner for espflash v2.x.x
rustflags = ["--cfg", "espidf_time64", "-C", "default-linker-libraries"]

Cheers,
Closing this issue due the lack of answers from the repository contributors.
Cheers,
ring 0.17 is the first version that has implementations of every algorithm that could work on every target. But, we do have an allowlist of target architectures and target operating systems. I do not know what riscv32imac-esp-espidf but it looks like riscv32 which has a good chance of working. The main question is whether the getrandom crate supports that target and if not then we probably need PR #1754 to be merged.
Hi @briansmith ,
thank you for your answer.
getrandom supports the target riscv32imac-esp-espidf with no problem for STD rust embedded apps.
[target.'cfg(all(target_arch = "riscv32imac",target_os = "espidf"))'.dependencies]
getrandom = { git = "https://github.com/rust-random/getrandom.git" }
So, does ring have support for riscv32 ?

You need to set TARGET_CC or equivalent to the C compiler for the target.
See also https://github.com/briansmith/ring/issues/1787 where I describe a bit of what's wrong with getrandom's implementation on this target.

Regrading getrandom
I am using getrandom in other places and I have no problems with it. Should I wait for the "in-library DRBG" for this to work with the ring library ?
Regarding the ring library:
I think I am doing something wrong. I have already tried several types of configurations but I am not able to compile the ring crate.
I have the "riscv-gnu-toolchain" with the enable-multilib meaning it would work for both 64-bits and 32 bits.

Hi, @briansmith
Is there any solution for this issue ?
Does Ring support our "riscv32imac-esp-espidf" target ? I have looked in the CI and did not find our target there.
Happy new year, cheers.
For me it fails due to riscv32-esp-elf-gcc not being supported - same error message.
Issue #1943 is related to this. PR #1944 is taking a step toward getting this working.
Usually I use Ubuntu, and also ring's CI normally runs on UBuntu. It would accelerate the process of supporting this target if somebody could document how to install the toolchain for this target on Ubuntu so that I can test that the build succeeds,
Pointers to other projects that support this target that have GitHub Actions working would also be appreciated.
It would be even better if somebody could submit a PR that modifies mk/{install-build-tools.sh,cargo.sh} and .github/workflows/ci.yml to add this target to CI, at least so that cargo.sh test --norun works.
