MacOS Sierra installation via homebrew fails

[colinramsay]

On MacOS Sierra Beta (16A239m), the installation via homebrew fails due to an unsatisfied dependency.

wxmac: This formula either does not compile or function as expected on OS X

By installing wxmac with the --devel flag, wxmac will install, but at this time elixir itself won't. I'm not sure how to get elixir to install that dev version of wxmac. It may be that this simply sorts itself out when wxmac pushes the devel version to stable, but this was a stumbling block for me and I thought I'd flag it in case any further action could be taken to ease this pain.

Hey @colinramsay, thanks for the report. However, I would say that this is not a bug with Elixir and maybe an issue should be opened in homebrew-core, where the Elixir formula lives. Wdyt?

[colinramsay]

Possibly! I wasn't sure where the ownership of this would lie. Homebrew also gives the following message:

Warning: You are using OS X 10.12.
We do not provide support for this pre-release version.
You may encounter build failures or other breakages.
Please create pull-requests instead of filing issues.

In other words, if I can't fix it, don't bring it up. I opened the issue here in the hope that someone familiar with elixir and homebrew could advise - perhaps one of the people who have contributed to the elixir formula.

What do you mean by Elixir won't install when using --devel for wxmac? Do
you have the error message?

You should be able to install Erland without wxmac though. So maybe try
installing Erlang first, without wxmac, and then try Elixir.

With wxmac-3.1.0_2 already installed via brew install --devel wxmac, brew install elixir just gives:

wxmac: This formula either does not compile or function as expected on OS X

I'll try installing Erlang first, thanks for the recommendation.

The elixir is failing because there is no --devel support for it. Can you
check the Erlang formula to see if you can install it without wxmac? I am
assuming a flag is needed or you will have to at least change the formula.

wxmac is only a recommended dependency of erlang, so I disabled it:

brew install erlang --without-wxmac
brew install elixir

Everything installs as expected.
