Hey there, it says, you need to install CMake. Did you try if this helps?

[vt-alt]

Thanks. With cmake installed it still fails needing clang-devel, and after installing it it succeeds. (While we have gcc and cmake/clang-devel is not required on other architectures) What it tries to build? Maybe we can install just the required package instead of building? Or just disable this feature on ppc64le (as this is not extremely important architecture for us)?

[vt-alt]

I'm closing since this is solved and I am building with cmale/clang-delve. Thanks again.

https://crates.io/crates/aws-lc-rs which gets pulled in by axum-server with the feature rustls.

It's building aws-lc-sys, which you could maybe circumvent, if you set AWS_LC_SYS_PREBUILT_NASM=1.

I'll keep this open, as we need to determine, if we want to pull in that dependency and feature. If people have rustic_server mostly behind a reverse proxy like nginx, I think we don't need that.

This issue is known:

• This crate breaks with the latest version of rustls (0.23.13) programatik29/axum-server#153
