It looks like you're building ring from source, but not from within a Git checkout. Thus, build.rs doesn't see

And finally I do cargo build. warning: [email protected]: In file included from C:\Users\lpirc.cargo\git\checkouts\ring-51509f604a4fd25b\70b59d6\include/ring-core/base.h:74, error: failed to run custom build command for It's the same error as #2008 (comment) |

This is xtensa-esp32s3-elf-gcc.exe --version output: xtensa-esp32s3-elf-gcc.exe (crosstool-NG esp-2021r2-patch5) 8.4.0 I added this to target.h: Now, when I compile it, I don't get any errors or warnings, but I don't know actually if it will work fine. |
|
In target.h, you can see: Ideally, you would upgrade to a newer version of GCC. Then it should "just work." Otherwise, you can find out what symbol to add to the above |
|
Yes, I wrote Xtensa with '__' as the beginning and end as you said, but in markdown double underscores are used to format text as bold, as you can see in the previous message. |
|
OK, it looks like somebody just needs to submit the PR. |
|
Do you want me to submit a PR with the lines I added for xtensa? |
^ Please extend that line. Incidentally, is there no newer version of the xtensa SDK that lets you use GCC 10 or higher? |
|
I changed to GCC 12 because now I'm using esp-idf 5.1, which requires GCC 12. |
https://www.esp32.com/viewtopic.php?t=1612 and other things seem to say that you may need |
|
@briansmith since I can't find a PR from @lorenzo-pirchio , I will create one myself. Furthermore, I'm on GCC V 13 (via crosstools) and still encounter the same error. |

@briansmith I can confirm building works with

im also trying to build rustls with ring on esp32, here is a fragment of my [dependencies]

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 (ed5b2a8), 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: esp-rs/rust#110
[unstable]
build-std = ["std", "panic_abort"]
[env]
MCU="esp32s3"
ESP_IDF_VERSION = "v5.1.3"
CRATE_CC_NO_DEFAULTS = "1"
`
This is what I get when I do cargo build:
