This file describes how to build and run wayland. See NOTES for what These instructions assume some familiarity with git and building and
wayland is or maybe will be some day. There's a google group for running experimental software. And be prepared that this project
wayland/eagle discussion here: isn't at all useful right now, it's still very much a prototype. When
the instructions suggest to clone a git repo, you can of course just
add a remote and fetch instead, if you have a clone of that repo
around already. I usually install all software I'm working on into
$HOME/install, so that's what I'll use in the instructions below, but
you can use your favorite directory of course or install over your
system copy (pass --prefix=/usr --sysconfdir=/etc, generally).

Wayland requires the eagle EGL stack available from Modesetting
git://people.freedesktop.org/~krh/eagle At this point, kernel modesetting is upstream for Intel, AMD and
nVidia chipsets. Most distributions ship with kernel modesetting
enabled by default and will work with Wayland out of the box. The
modesetting driver must also support the page flip ioctl, which only
the intel driver does at this point.
and currently assumes that eagle is checked out in a sibling
directory, for example:
~krh/src/wayland and Building mesa
~krh/src/eagle
Eagle should work with a recent DRI driver from mesa, but I have mesa Wayland uses the mesa EGL stack, and all extensions required to run
repo with an eagle branch here: EGL on KMS are now upstream on the master branch. The 7.9 release of
mesa will have all these extensions, but for now you'll need to build
mesa master:
git://people.freedesktop.org/~krh/mesa $ git clone git://anongit.freedesktop.org/mesa/mesa
$ cd mesa
$ ./configure --prefix=$HOME/install --enable-egl --enable-gles2
$ make && make install
which provides and experimental DRI CopyBuffer extension, that lets If you're using an intel chipset, it's best to also pass

this branch to be able to use the CopyBuffer extension.
To run wayland you currently need intel hardware, a kernel with gem
and kernel modesetting, and it is necessary to set a couple of
environment variables. First, set LD_LIBRARY_PATH:
export LD_LIBRARY_PATH=$PWD:$PWD/../eagle libxkbcommon
Yes, this sucks, but libtool sucks more. Then to let eagle pick up Wayland needs libxkbcommon for translating evdev keycodes to keysyms.
the custom dri driver, set There's a couple of repos around, and we're trying to consolidate the
development, but for wayland you'll need the repo from my get
repository. For this you'll need development packages for xproto,
kbproto and libX11.
export EAGLE_DRIVER_PATH=$PWD/../mesa/lib $ git clone git://people.freedesktop.org/~krh/libxkbcommon.git
$ cd libxkbcommon/
$ ./autogen.sh --prefix=$HOME/install
$ make && make install
and finally set up the path to the evdev device to use as a pointer
device:
export WAYLAND_POINTER=/dev/by-id/whatever-it's-called-event-mouse cairo-gl
If you haven't already, load the i915 driver with modesetting: The Waland clients render using cairo-gl, which is an experimental
cairo backend. It has been available since cairo 1.10. Unless your
distribution ships cairo with the gl backend enabled, you'll need to
compile your own version of cairo:
modprobe i915 modeset=1 $ git clone git://anongit.freedesktop.org/cairo
$ cd cairo
$ ./autogen.sh --prefix=$HOME/install --enable-gl
$ make && make install
You may need to unload it first, if it's loaded already. Also, on
Fedora, there may be a bogus /etc/modprobe.d/i915modeset preventing
the modeset paramater from reaching the module. Nuke it.
At this point you should be able to launch wayland and a couple of Wayland
clients. Try something like:
./wayland & With mesa and libxkbcommon in place, we can checkout and build
./background <some png/jpg image smaller than 1024x768> & Wayland. Aside from mesa, Wayland needs development packages for
./flower & gdk-pixbuf-2.0, libudev, libdrm, xcb-dri2, xcb-fixes (for X
./flower & compositor) cairo-gl, glib-2.0, gdk-2.0 (for poppler) and
./flower & poppler-glib:
./window &
./pointer &
Maybe some day there'll be a script that does all this. Some day... $ git clone git://people.freedesktop.org/~krh/wayland
$ aclocal; autoconf; ./configure --prefix=$HOME/install
$ make && make install
And after all this work it may still not work or even oops your Installing into a non-/usr prefix is fine, but the 70-wayland.rules
kernel. It's very much work in progress, so be prepared. udev rule file has to be installed in /etc/udev/rules.d. Once
installed, either reboot or run
cheers, $ sudo udevadm trigger --subsystem-match=drm --subsystem-match=input

to make udev label the devices wayland will use.
If DISPLAY is set, the wayland compositor will run under X in a window
and take input from X. Otherwise it will run on the KMS framebuffer
and take input from evdev devices. Pick a background image that you
like and copy it to the Wayland source directory as background.jpg or
use the -b command line option:
$ ./wayland-system-compositor -b my-image.jpg
To run clients, switch to a different VT and run the client from
there. Or run it under X and start up the clients from a terminal
window. There are a few demo clients available, but they are all
pretty simple and mostly for testing specific features in the wayland
protocol: 'terminal' is a simple terminal emulator, not very compliant
at all, but works well enough for bash
'flower' moves a flower around the screen, testing the frame protocol
'gears' glxgears, but for wayland, currently broken
'image' loads the image files passed on the command line and shows them
'view' does the same for pdf files, but needs file URIs
(file:///path/to/pdf)
