Potential M1 race conditions

[jasonwc]

There are a few interesting race conditions we encountered that I'd like to document here:

• There is plenty of shell stuff that needs to be loaded into the path. This can be problematic for a number of reasons:
  • If you don't have the correct ENV, you might compile incorrectly for various platforms (e.g. M1)
  • Some flags are in local projects, but if you don't have direnv setup yet, you can break yourself if you try to bin/dev/doctor but aren't sourcing the direnv compile flags
  • Personally, I want most of this stuff in my dotfiles repo. But this means you need a temporary place to but "setup env" until you can replace it with your full set of tools, dotfiles, etc...

In the end I created a .setup-profile file and source it in my .zshrc so that its clear that this is env for "setup" that I'll probably not need once my real .zshrc file is set.

Here's the contents of that file after going through a full set of setup to get to bin/dev/test on apex:

export PKG_CONFIG_PATH="$(brew --prefix)/opt/openssl/lib/pkgconfig"

# to fix some c library compilation errors: https://apple.stackexchange.com/questions/414622/installing-a-c-c-library-with-homebrew-on-m1-macs
export CPATH=/opt/homebrew/include
export LIBRARY_PATH=/opt/homebrew/lib

# https://direnv.net/docs/hook.html
eval "$(direnv hook zsh)"

. $HOME/.asdf/asdf.sh```

Ultimately a lot of these are "geometer" concerns and not necessarily "medic" concerns, but starting to figure out separation of responsibilities would be good.

From a Geometer perspective, we should probably differentiate between "laptop setup" with medic and "application setup" with medic. @sax and I also discussed that we should be fairly unopinionated, but its important for Geometer employees to have a good shared workstation and a quick path to devving. But it should be really easy to layer personal setups on top of it without messing up Geometer specific things. And then of course, what of this (if any) should be part of a medic baseline.
