PawPaw

PawPaw is a Cross-Platform build scripts setup for static libraries and audio plugins

It was created out of the need of many open-source developers to easily build their stuff for macOS and Windows,
where usually dependencies are involved which need to be built manually.

In order to make audio plugins self-contained, these dependencies/libraries need to be built statically,
which most packaging projects do not do.

Also, most open-source audio plugin projects do not have binaries for macOS or Windows,
making it very difficult for users in these platforms to enjoy them.

This project was created as a way to do automated macOS and Windows builds of such projects and libraries,
so we can finally have a good collection of LV2 plugins on these system.
The same automated setup can then be re-used/extended to support other projects and applications.

Goals

PawPaw has the following goals:

• Single script to build most common plugin dependencies statically, both natively and cross-compiling
• Clean and simple code, easy to maintain and add new libraries to build
• Statically build LV2 plugins for (at least) macOS and Windows
• Define each plugin project in its own file, to make it easy to support new plugins via pull-request
• Package the entire collection as an installer

Additionally, PawPaw is used to build library dependencies for Cardinal, Carla, JACK2 and mod-app.

For developers

Proper documentation on how to setup PawPaw for your own project will come at a later date.
But roughly all that is needed is something like:

# change dir to PawPaw root folder
cd /path/to/PawPaw

# build plugin dependencies for win64 target (only needed once)
./bootstrap-plugins.sh win64

# set up environment variables for win64 builds with PawPaw static libs
source local.env win64

# change dir to your own project
cd /path/to/my/project

# build as usual
make # or whatever other build system applies

On MacOS

Prerequisites

Based on Sonoma 14.2.1 running on an M1 based MacBook, the following are needed:

• Xcode command line tools https://mac.install.guide/commandlinetools/about-xcode-clt.html

As well as:

• autoconf
• automake
• cmake
• coreutils
• gawk
• gnu-sed
• jq
• make
• meson

A great way of installing these is using Homebrew "The Missing Package Manager for macOS". You can install Homebrew by visiting https://brew.sh/

The brew command to install the dependencies listed above is:

brew install autoconf automake cmake coreutils gawk git gnu-sed jq make meson
