@@ -17,114 +17,19 @@ protocol does not handle rendering, which is one of the features that makes wayland so simple. All clients are expected to handle rendering themselves, typically through cairo or OpenGL. -The wayland repository includes a compositor and a few clients, but -both the compositor and clients are essentially test cases. - - -Building Instructions - -The instructions below assume some familiarity with git and building -and running experimental software. And be prepared that this project -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). - - -Modesetting - -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. - - -Building mesa - -Wayland uses the mesa EGL stack, and all extensions required to run -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 clone git://anongit.freedesktop.org/mesa/mesa - $ cd mesa - $ ./configure --prefix=$HOME/install --enable-egl --enable-gles2 - $ make && make install - -If you're using an intel chipset, it's best to also pass ---disable-gallium to ./configure, since otherwise libEGL will try to -load the gallium sw rasterizer before loading the Intel DRI driver. - - -libxkbcommon - -Wayland needs libxkbcommon for translating evdev keycodes to keysyms. -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 git -repository. For this you'll need development packages for xproto, -kbproto and libX11. - - $ git clone git://people.freedesktop.org/~krh/libxkbcommon.git - $ cd libxkbcommon/ - $ ./autogen.sh --prefix=$HOME/install - $ make && make install - - -cairo-gl - -The Wayland 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: - - $ git clone git://anongit.freedesktop.org/cairo - $ cd cairo - $ ./autogen.sh --prefix=$HOME/install --enable-gl - $ make && make install - - -Wayland - -With mesa and libxkbcommon in place, we can checkout and build -Wayland. Aside from mesa, Wayland needs development packages for -gdk-pixbuf-2.0, libudev, libdrm, xcb-dri2, xcb-fixes (for X -compositor) cairo-gl, glib-2.0, gdk-2.0 (for poppler) and -poppler-glib: - - $ git clone git://people.freedesktop.org/~krh/wayland - $ ./autogen.sh --prefix=$HOME/install - $ make && make install - -Installing into a non-/usr prefix is fine, but the 70-wayland.rules -udev rule file has to be installed in /etc/udev/rules.d. Once -installed, either reboot or run - - $ 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) +The weston compositor is a reference implementation of a wayland +compositor and the weston repository also includes a few example +clients clients. + +Building the wayland libraries is fairly simple, aside from libffi, +they don't have many dependencies: + + $ git clone git://anongit.freedesktop.org/wayland/wayland + $ cd wayland + $ ./autogen.sh --prefix=PREFIX + $ make + $ make install + +where PREFIX is where you want to install the libraries. See +http://wayland.freedesktop.org for more complete build instructions +for wayland, weston, xwayland and various toolkits.
