Describe the bug

Hi 👋

When I run forge test it automatically downloads the $HOME/.svm/0.8.11/solc-0.8.11 binary for Linux to compile my contracts. However, it downloads amd64 version of the binary even though I'm running aarch64 version of Linux.

When I manually replace the binary with aarch64 version of the binary forge test puts amd64 version back.

What could I do in this case to use forge test on aarch64 Linux?

Thanks!

The bug is in svm-rs here.

Then we'd need to:

1. Update svm-rs in ethers-solc
2. Update ethers-solc here in Foundry

[onbjerg]

Ok, so it doesn't seem like there are any Solidity arm64 binaries available going by https://github.com/ethereum/solc-bin.

If you want to run with a custom version, try passing the --no-auto-detect flag - it should keep the binary intact 😄

nevertheless we should check for arm on svm-rs cc @roynalnaruto

[onbjerg]

True, the platform detection should be more robust by checking the arch in general

@onbjerg @mattsse I had noticed this some time ago, probably slipped out of my TODOs. The above PR looks good, although it would show an M1 macbook as unsupported (check my comment on the PR).

This should be fixed the next time we do an update of svm-rs in ethers-solc and update ethers-solc here
