How to setup Zynthian to compile and run these wrappers

Here are the minimal, step-by-step instructions to configure your Zynthian for compiling the C++ wrappers directly via SSH:

Prerequisites & Setup on Zynthian

1. Connect via SSH

Open your terminal (PowerShell, Command Prompt, macOS/Linux Terminal) and connect to your Zynthian as root:

ssh root@zynthian.local

(Default password on Zynthian is opensynth)

2. Install Compiler Tools & LV2 Headers

Install g++, make, and the LV2 development header files (lv2-dev provides <lv2/core/lv2.h>, <lv2/worker/worker.h>, etc.):

apt-get update

apt-get install -y build-essential lv2-dev

How to Compile a Generated Wrapper

Once the tools are installed, you can build any generated wrapper in seconds:

1. Copy the Wrapper Bundle

Extract your .lv2.zip bundle and copy the plugin folder (e.g. Vitalium_Analog_Brass_wrapper_cpp.lv2) to:

/zynthian/zynthian-plugins/lv2/
(You can use SFTP / FileZilla or scp to transfer it)

2. Run the Build Script

Navigate to the directory on Zynthian and execute:

cd /zynthian/zynthian-plugins/lv2/Vitalium_Analog_Brass_wrapper_cpp.lv2

build.sh
(Alternatively, you can run the direct g++ command):

g++ -O2 -fPIC -shared wrapper.cpp -o Vitalium_Analog_Brass.so -Wl,-z,nodelete -ldl -lpthread

Register on Zynthian

Open the Zynthian Webconf in your browser: http://zynthian.local
Navigate to SOFTWARE → Engines.
Click “Scan for Engines” and toggle the new engines.
Click “SYSTEM → Reboot” or execute systemctl restart zynthian via SSH

The new synth engine will now show up in your instrument list.
