Installing from source on an M1 Mac

[milancermak]

TL;DR:
All I had to do to build from source on an M1 Mac is adding this line to [dependencies] in programs/bpf_loader/Cargo.toml:

openssl = { version = "0.10", features = ["vendored"] }

Problem

There's a problem when developing for Solana on an M1 Mac as is evident by various issues on here (e.g. #19743 or #17406) or by others on Stack Overflow. There's not really a good solution, the commonly accepted one seems to be to use Rosetta and reinstall the whole toolchain. I didn't want to go down that route so I tried cloning the repo and compiling from scratch.

Proposed Solution

I already had brew install openssl and brew install coreutils (due to the greadlink dependency in cargo_install_all.sh). The only thing I needed to change was adding openssl as a dependency to Cargo.toml in bpf_loader as mentioned above.

I'm new to Solana and I don't know enough to send a PR, but I was hoping you could incorporate this to offer native M1 builds for the community.

This works 👍 Could you open a PR so the Solana folks can give a review and hopefully merge this change into the next release?

It turns out that the openssl crate people fixed the homebrew integration back in February. Sent you a PR that just bumps the version and seems to work.
