picom is a compositor for X, and a fork of Compton.

This is a development branch, bugs to be expected

Assuming you already have all the usual building tools installed (e.g. gcc, python, meson, ninja, etc.), you still need:

• libx11
• libx11-xcb
• xproto
• xcb
• xcb-util
• xcb-damage
• xcb-xfixes
• xcb-shape
• xcb-renderutil
• xcb-render
• xcb-randr
• xcb-composite
• xcb-image
• xcb-present
• xcb-glx
• pixman
• libconfig (>= 1.7)
• libdbus (optional, disable with the -Ddbus=false meson configure flag)
• libGL, libEGL, libepoxy (optional, disable with the -Dopengl=false meson configure flag)
• libpcre2 (optional, disable with the -Dregex=false meson configure flag)
• libev
• uthash

If libconfig >= 1.7 is not available on your system, meson will try to build it from git. In which case, you also need cmake, and git.

On Debian based distributions (e.g. Ubuntu), the needed packages are

libconfig-dev libdbus-1-dev libegl-dev libev-dev libgl-dev libepoxy-dev libpcre2-dev libpixman-1-dev libx11-xcb-dev libxcb1-dev libxcb-composite0-dev libxcb-damage0-dev libxcb-glx0-dev libxcb-image0-dev libxcb-present-dev libxcb-randr0-dev libxcb-render0-dev libxcb-render-util0-dev libxcb-shape0-dev libxcb-util-dev libxcb-xfixes0-dev meson ninja-build uthash-dev

On Fedora, the needed packages are

dbus-devel gcc git libconfig-devel libev-devel libX11-devel libX11-xcb libxcb-devel libGL-devel libEGL-devel libepoxy-devel meson pcre2-devel pixman-devel uthash-devel xcb-util-image-devel xcb-util-renderutil-devel xorg-x11-proto-devel xcb-util-devel

To build the documents, you need asciidoctor

$ meson setup --buildtype=release build
$ ninja -C build

Built binary can be found in build/src

If you have libraries and/or headers installed at non-default location (e.g. under /usr/local/), you might need to tell meson about them, since meson doesn't look for dependencies there by default.
