macOS M1: running rake db:setup fails pointing to ffi gem

[belgoros]

I have the following ffi versions installed:

*** LOCAL GEMS ***

ffi (1.15.5, 1.9.25)
ffi-compiler (1.0.1)
llhttp-ffi (0.3.1)
public_suffix (3.0.3)

I had to install 1.9.25 version as follows:

gem install ffi -v '1.9.25' -- --disable-system-libffi --with-cflags=-Wno-implicit-function-declaration

When running bundle on a project using Ruby 2.7.5 version, everything goes well.
Then, when running rake db:setup it fails as follows:

rake db:setup

I'm on macOS 12.3.1, Apple M1 chip.

What am I missing?

I am facing the same issue

[belgoros]

As the Rails app I'm working on, uses ruby 2.7.5 version, I had to install Rosetta terminal as follows:

• run /usr/sbin/softwareupdate --install-rosetta --agree-to-license
• In your finder, go to the Applications folder where you will find the Terminal.app
• Right-click on the copy from the previous step and select Get Info
• Rename this app Term-x86 and check the box next to Open using Rosetta
• Exit out of the window to save, then open your new Term-x86
• To confirm that you configured your Rosetta terminal correctly, enter arch. If it’s configured correctly, it will return i386.

So to have all the dependencies work smoothly in the Rosetta terminal, I also had to install homebrew from inside the Rosetta terminal, because the installation paths are different for M1 and i386 Terminal.

Hope this helps waiting for the fix to come.

Hi @belgoros could you please check if my PR can help you with this?
#936
This will try to use arm64 libraries if they are available (installed via arm64 homebrew)
