Building the VCV Rack Plugin

You must have the Rack-SDK on your computer already. Set the environment variable RACK_DIR equal to the path to the location of Rack-SDK. For instance, add this to your .bashrc or .zshrc:

export RACK_DIR=/Users/MyName/projects/Rack-SDK

You will need a recent c++ compiler such as gcc-12 or later, or clang-14 or later.

Make sure to clone all submodules:

git submodule update --init --recursive

To build and the plugin, run:

make dep
make dist

To install the plugin in your local VCV Rack plugin directory:

make install

The next time you start VCV Rack, it will load the modified plugin.

If you are developing or modifying the code, then use the cmake interface for building (it will handle dependencies and rebuild only what needs to):

# Configure cmake (only need to do this once):
make dep

# Then do this to rebuild after making changes:
cmake --build build

# Install normally:
make install

To run the unit tests:

make tests
