Review build, compile, and install steps for Lotus.

[johnnymatthews]

The Lotus compile and build steps may be out of date. They list Homebrew as a MacOS install option, which I'm pretty sure got halted a while ago.

Steps

• Linux

  • Review dependencies. Some may be un-used.
  • Review compile and build process.

• MacOS

  • Find out if Homebrew is actually still supported.
  • Review dependencies.
  • Review compile and build process.
    • Pay special attention to the compile process for Apple Silicon. We used to require special M1 flags to build, but that might not be the case anymore.

@johnnymatthews I can take this one

@ianconsolata Homebrew is still supported right?

Looks like it, the release was just updated 3 days ago when the new build was published https://github.com/filecoin-project/homebrew-lotus. You should be able to run brew install filecoin-porject/lotus/lotus to install it, or use brew tap filecoin-project/lotus && brew install lotus

In particular, it should be working on both Apple Silicon and non-Silicon macs. When testing the lotus build process, if you find those special build flags are no longer needed for Apple Silicon please let me know -- the build process for generating the MacOS binaries is a little clunky right now because of those flags, and because at the time I could only get it to work if it is was building on an Apple Silicon VM. If you can get it to build without those flags on a non-Silicon environment using only GOARCH and GOOS flags, that would simplify the lotus build process significantly.

Just double checked, and I has a weird issue installing it the first time, but after cleaning and trying again it seemed to work without a hitch. Not sure what might have caused the issue the first time, but if you encounter anything similar please flag and I can dig in further:
