Public Service Announcement: Io and Prolog on Mac OS X

August 21, 2011 - 1 minute read -

A quick public service announcement for anyone else currently working through Seven Languages in Seven Weeks on a Mac.

Chapter 3’s language, Io, does not currently compile on Mac OS X if you attempt installation via Homebrew. This patch should fix it once it has been pulled into Io master.

Chapter 4’s language, Prolog, can be installed from the GNU Prolog web site. It installs to an odd location, /opt/local/bin, which you will need to add to your path to get it working properly.

Hope that helps someone else out there!
