I don't see the C library of aws-lc mentioned anywhere in the linker invocation. Can you show the stdout/stderr of the build script of aws-lc-sys? You should be able to find it in the |

Can you also build with |

I forgot to note that I am using Ubuntu 22.04 LTS. (In case this is relevant to the issue) |

I can reproduce this problem locally. What is strange however is that |

Found the problem: aws-lc-sys is using the Edit: Seems like rust-bindgen has been doing this for 7 years. How did that not get noticed until now? |

Encountered this as well trying to use cranelift on a crate which depends on crates that depend on rustls, which is a large swath of the network ecosystem, this is a blocker to using cranelift for faster compiles in our dev loop |

Yeah same as above, getting |

Still getting this same issue with latest nightly |

This still needs either a decision if we want to actually officially support |

For those who encounter this issue, you can just do this: rustls = { version = "0.23", default-features = false, features = ["ring"] }For unknown reason, |

@Logarithmus ring just got an unmaintained advisory: https://rustsec.org/advisories/RUSTSEC-2025-0007.html |

Still want this to work |
|
Would this be fixed by rust-bindgen#3175 or are there other changes that would be necessary? |
|
rust-lang/rust-bindgen#3175 is not going to work I think. I do have an idea for another method to fix this in rust-bindgen though. |
|
Still interested in this being resolved |
If you don't mind documenting what you think the fix is (whether here or in rust-bindgen), I believe @ActuallyHappening just volunteered to, by sheer force of will, submit a PR. |
