Building and installing Sozi from sources

Get the source files

Clone the repository:

git clone git://github.com/sozi-projects/Sozi.git

Install the build tools and dependencies

The following instructions work successfully in Ubuntu 22.04.

Install Node.js and Gulp. The build script for Sozi is known to work with Node.js 14 from Nodesource.

sudo apt install nodejs
sudo npm install --global gulp-cli

From the root of the source tree, run:

npm install

If you plan to build a Windows executable, also install wine. In Debian/Ubuntu and their derivatives, you can type the following commands.

dpkg --add-architecture i386
sudo apt update
sudo apt install wine wine32

If you plan to build Debian packages, install the following additional packages:

sudo apt install devscripts debhelper

If you plan to build Redhat packages, install the following additional packages:

sudo apt install rpm

If you plan to build Archlinux packages, install the following additional packages:

sudo apt install libarchive-tools

The zip compression tool must also be installed:

sudo apt install zip

Get the binaries for ffmpeg (optional, but video export will not work without them). Download and unzip the FFMPEG executables to the following folders:

• Linux 32-bit: resources/ffmpeg/linux-ia32
• Linux 64-bit: resources/ffmpeg/linux-x64
• Windows 32-bit: resources/ffmpeg/win32-ia32
• Windows 64-bit: resources/ffmpeg/win32-x64
• MacOS X 64-bit: resources/ffmpeg/darwin-x64

Build

To build and run the desktop application without packaging it, run the following commands from the root of the source tree. At startup, Sozi will show an error notification that can be ignored.

gulp
npm start

To build and package the desktop application for all platforms, do:

gulp all

After a successful build, you will get a build/dist folder that contains the generated application archives for each platform.

Helping debug Sozi

While Sozi is running, press F12 to open the developer tools. Check the Console tab for error messages.

Some environment variables will enable debugging features in Sozi. When running Sozi from the command line, you can add one or more variable assignments like this:

SOME_VAR=1 SOME_OTHER_VAR=1 sozi my-presentation.svg

Where SOME_VAR and SOME_OTHER_VAR are variable names from the first column of this table:

Variable	Effect
ELECTRON_ENABLE_LOGGING	Display JavaScript console messages in the current terminal window.
SOZI_DEVTOOLS	Open the developer tools immediately. This can be useful if F12 has no effect or when you want to debug events that happen at startup.
