Compiling the JUCE Audio Plugin Host

This week we'd like to start working with audio/midi plugins in JUCE. To test out your plugins, it's nice to have a lightweight host to run them inside where you can easily patch different plugins together. This tool is actually included with the JUCE library, but it needs to be compiled for your platform. Below are instructions to do so.

Instructions

Locate the JUCE folder on your computer and change to this directory (in my case /Applications/JUCE)
Navigate to extras/AudioPluginHost
Open the file AudioPluginHost.jucer in the Projucer
Export the Project to your IDE of choice

Setting up CMake for Eigen Library

Yes. THE EIGEN Library.
It is the library lures engineers first by its name then its capability in matrix manipulation that we've only seen in good expensive almighty slow MATLAB, specifically in C++.

Yes, from my experience so far, Eigen Library is AWESOME. It gives the users a giant freedom AND efficiency in matrix operations in a way I wouldn't even be able to even think about to implement alone.

YES IT IS FREE TO USE!

Problem

You have installed GPG, then tried to commit and suddenly you see this error message after it:
