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
Those are required by almost every component.
