System information

I am not familiar with Rust programming. I found this thread that seems surface-similar to the error I received, and so I thought perhaps it was an architecture-specific problem; I am running on arm64 on an M1 Mac. However I see the same error on an x86 Mac.

OS and arch for both systems:

Hi @eugeneia and @vipyne - thanks for what appears to be a super useful project! I'm very new to Rust programming and am not sure how to debug the build error. Could you point me in the right direction? Thanks!

[vipyne]

Hi @jasonm , thanks for taking a look. What is the output of $ rustc -V and $ rustup -V ?

[jasonm]

Hi @vipyne thanks for your message! I ended up opening #3 and included my notes below.

Versions of rustc and rustup

The cargo build command is executing as part of building a docker image per the Makefile/Dockerfile in this repo, so here's the version of rustc and rustup from the intermediate docker image layer immediately prior to the failing cargo build command:

~/dev/synthetic-network $ docker run -it --rm 04ca521c91d6 /bin/bash

root@4cb8abbf11ca:/opt/lib/rush# rustc -V
rustc 1.60.0-nightly (5e57faa78 2022-01-19)

root@4cb8abbf11ca:/opt/lib/rush# rustup -V
rustup 1.24.3 (ce5817a94 2021-05-31)
info: This is the version for the rustup toolchain manager, not the rustc compiler.
info: The currently active `rustc` version is `rustc 1.60.0-nightly (5e57faa78 2022-01-19)`

Here's the full docker build ... command that resulted in this image, so you can see where the 04ca521c91d6 came from.

Looks like the Dockerfile in this repo is always installing the latest nightly build of rust.

Namespacing the asm! macro

I spent a little more time reading the rust-lang/rust#84019 thread I found earlier, and figured I'd try fiddling with the source to see if I could move things forward.

I namespaced the asm! macro and voila! It built! Well, it complained with a warning, but that seems harmless:

Step 11/15 : RUN cargo build --release

  = note: `#[warn(stable_features)]` on by default

De-feature-ing asm

Removing the feature line caused the compilation to succeed with no warnings.

Fixed with #3
