warning: ring@0.17.8: cc1.exe: warning: C:\ring-main\ring-main\pregenerated: No such file or directory [-Wmissing-include-dirs]
It looks like you're building ring from source, but not from within a Git checkout. Thus, build.rs doesn't see .git/ and so it is expecting some files in pregenerated/. But they are not there, because they only exist in the package that's uploaded to crates.io.
cargo build
What is the exact command line of cargo build. As you can see in BUILDING.md, you need to set TARGET_CC and TARGET_AR to the correct C compiler.

Hi, I'm working on a project on esp32s3, I need to use rustls but I have problems with the ring crate since xtensa is not supported . I'm using the esp32-idf-template (https://github.com/esp-rs/esp-idf-template), and I changed the depedencies adding the ones I needed. As suggested by @briansmith, I am using the latest commit on the main branch, checking if there is this change (https://github.com/briansmith/ring/commit/ed5b2a86cccfe30e670b33536fc7e494fb5e9e19), but It still doesn't work. To be sure that I was using the latest commit, I downloaded the repo and added it as a local dependency.
This is my cargo.toml:
`[package] name = "s3_rust" version = "0.1.0" edition = "2021" resolver = "2" rust-version = "1.71"
[[bin]] name = "s3_rust" harness = false # do not use the built in cargo test harness -> resolve rust-analyzer errors
[profile.release] opt-level = "s"
[profile.dev] debug = true # Symbols are nice and they don't increase the size on Flash opt-level = "z"
[features] default = ["std", "embassy", "esp-idf-svc/native"]
pio = ["esp-idf-svc/pio"] std = ["alloc", "esp-idf-svc/binstart", "esp-idf-svc/std"] alloc = ["esp-idf-svc/alloc"] nightly = ["esp-idf-svc/nightly"] experimental = ["esp-idf-svc/experimental"] embassy = ["esp-idf-svc/embassy-sync", "esp-idf-svc/critical-section", "esp-idf-svc/embassy-time-driver"]
[dependencies] log = { version = "0.4", default-features = false } esp-idf-svc = { version = "0.48", default-features = false }
[target.'cfg(target_os="espidf")'.dependencies] ring = {path="C:/ring-main/ring-main", features =[ "less-safe-getrandom-espidf"] } rustls = { version = "0.23.7", default-features = false, features = ["ring", "logging", "std", "tls12"] }
[build-dependencies] embuild = "0.31.3" `
This is my config.toml: `[build] target = "xtensa-esp32s3-espidf"
[target.xtensa-esp32s3-espidf] linker = "ldproxy" runner = "espflash flash --monitor" # Select this runner for espflash v2.x.x rustflags = [ "--cfg", "espidf_time64"] # Extending time_t for ESP IDF 5: https://github.com/esp-rs/rust/issues/110
[unstable] build-std = ["std", "panic_abort"]
[env] MCU="esp32s3" ESP_IDF_VERSION = "v5.1.3" CRATE_CC_NO_DEFAULTS = "1" `
