Since I'm new to Ubuntu and I had a hard time installing Io language, I've decided to record my steps. Hopefully I'll remember all of them and other people won't struggle as much as I did. I'm running Ubuntu 11.10.
The main problem I had was that I did not have all the dependencies needed to install Io and the installation was failing. The dependencies are yajl and libevent
If you've got then installed, you can skip the next steps.
NOTE: You will need to have cmake and make. You can install them running the following commands from the terminal:
Open the terminal and go to the folder you extracted libevent
Run the following commands
For more information please check: http://libevent.org/ Also check the README file inside the .tar.gz for your version
Installing Io language
You can go to the Io language website and download the language or click here to go start downloading it. As there is no Ubuntu package for that, you will be downloading the Io's source code. This will point to Steve Dekorte's version. I ended up downloading Jeremy Tregunna's version. It should work the same. Check each one is the most up-to-date.
Open the terminal and go to the folder you extracted Io
Run the following commands:
IMPORTANT: When running cmake .., you may get a few errors. Even then, try to run sudo make install. Some libraries may fail to compile because they are OS specific.
