Update to newer rust version?
Luro02 opened this issue · 2 comments
The rust version in the Dockerfile is from about one year ago, and a lot of new features have been implemented since then.
Line 8 in a2ea65c
I tried to change the rust version in the Dockerfile to the latest nightly:
- RUST_VERSION=nightly-2020-08-26 \
+ RUST_VERSION=nightly-2021-08-20 \which resulted in a compilation failure:
Compiling rudra v0.1.0 (/tmp/rudra)

The rustc-dev and llvm-tools-preview rustup components need to be installed. I just suggested #9 to let rustup install them automatically.
When you change the rust version I think what happens is that the dockerfile installs these components for the new toolchain version, but then when it changes to the source directory rust-toolchain overrides the toolchain version to the older one for which the dockerfile doesn't install the necessary components.
We plan to update the supported compiler version when all the evaluation for our paper is done. Meanwhile, you can use bjorn3's forked branch.
