Request to tag a version of Cling which builds on macOS

Hi, I’m a contributor to Homebrew (package manager for macOS)
By creating a Homebrew Formula for Cling, users of Cling would be easily able to install and use cling by just running brew install cling

I created a Pull request for the same here:
According to Homebrew guidelines, a git tag in the upstream repository is to be specified in Homebrew Formula. But the latest v0.4 tag doesn’t build.

Can you please tag a version which builds?

Below are the build time errors that I’m facing in macOS Sierra 10.12.6

Yikes! Which compiler is that?

(And thanks for trying to put cling into Homebrew!)

Hi Axel. Please let me know if you need any other info?
I even tried v0.3 even that doesnt build. But latest head builds without any errors.

I think we’ll just tag a new version. I will let you know during the coming days.

Thanks! Looking forward to it.

@Axel Gentle ping.

I haven’t forgotten you - I simply did not find a time slice for this yet. I’ll be back in two weeks and expect to do it then.
