problem compiling Keysas library unstable

[Thibautdbr]

Good morning,
I have already managed to install keysas on debian 12 in the past, I wanted to try again but when compiling Keysas just after cloning the gitlab repository I was given this error:

Some errors have detailed explanations: E0635, E0658.
For more information about an error, try rustc --explain E0635.
error: could not compile curve25519-dalek (lib) due to 5 previous errors

so I wanted to add #![feature(stdarch_x86_avx512)] at the beginning of the .rs files but nothing works, I still have the same error. Could you help me resolve this issue please.

Hi,

First, you should clone the Develop branch as the master branch is getting outdated.
Then, try this :
rustup update && cargo update
and finally
make build

Keep me in touch

good evening, there was a problem with the new version curve25519-dalek updated on February 5, 2004, so I installed the old version of nightly and it worked
rustup install nightly-2024-02-03
rustup default nightly-2024-02-03
. See you later to find a stable solution for the new version of curve25519-dalek.
Thank you for your help

Hi,

Curve25519-dalek has been patched to address this issue.
No needs to install an older version of the compiler, a simple "cargo update" should be sufficient.
Cheers
