Dependencies

Most of these dependencies should be installed automatically when you install official packages.
Unless otherwise stated, the dependencies are all optional.

The tools required for building all of these projects are not listed here.
Typically, you will need: gcc or clang, gnu-make, libiconv, gettext, cmake, autoconf, automake, pkg-config or pkgconf, bison, flex, intltool, etc For building xpra itself and some of the python modules, you will also need Cython

Core Dependencies

Those are required by almost every component.

Project Source Download Link Purpose Client or Server Notes
glib https://ftp.gnome.org/pub/gnome/sources/glib/ low-level library both Required
gtk http://ftp.gnome.org/pub/gnome/sources/gtk+/ UI Toolkit both Required (*)
PyGObject https://pypi.org/project/PyGObject/#files Bindings for GObject based libraries such as GTK and GStreamer both Required (*)

(*) needed for running any kind of server, or GUI clients. It is not required for running text-only clients like xpra top or xpra info.
