Can anyone help with installing rust on a raspberry pi.

After installing rust, using

curl --proto ‘=https’ --tlsv1.2 -sSf https://sh.rustup.rs | sh
source ~/.cargo/env

even when changing terminals
when I try to run cargo… I get…

cargo no such file or directory (os error 2)

GOT IT TO WORK :partying_face: :partying_face: :partying_face: :partying_face:

Google is your friend

  1. Download the installer as per the link above:

Code: Select all

$ curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
  1. When prompted select option “2) Custom installation”
  1. When prompted for “Default host triple?” enter “arm-unknown-linux-gnueabihf”

Other options are up to you, I selected “nightly” for the default toolchain, “complete” for the profile and “y” to update my PATH. And finally 1) to kick off the installation.

After that “cargo” works fine again.

I have an error on api / cli cross-compilation, with the last version :

Compiling cpufeatures v0.1.1
error[E0432]: unresolved import `libc::HWCAP_AES`
  --> /home/richard/.cargo/registry/src/github.com-1ecc6299db9ec823/cpufeatures-0.1.1/src/aarch64.rs:55:21

   |                       ^^^^^^^^^^^^ no `HWCAP_AES` in the root

Node compilation is ok though

Compiling on the raspberry pi was a success, though when it finally compiled test net 5.1 was released. :joy::joy::joy:

Will join the test net at some point soon.

… and want to test if I can put my node on my new external nvme 1TB drive.

It would be great if ever you have time in the next Testnet to share the compiled binaries :innocent:

I have tried to install rust on my RPi 4 with your guide, but it fails invariably with a memory allocation error when downloading rustc.

I think the team did they were going to soon start including bins for pi.
