This is an alternative to developing with a --prefixed
installation, and is a familiar workflow for developers
coming from some projects (such as gstreamer). Compared to
a prefixed installation it saves a small amount of time
(primarily due to relinking during make install) and
space.
The wl_uninstalled script provides a shell environment to
build and use an uninstalled Wayland/Weston setup.
For example, this script and a fresh checkout of Wayland,
libinput, wayland-protocols and Weston is all you need to
run Weston from the uninstalled environment created by
building every module. No installation required.
Quick instructions:
Lets use Weston as an example altough other Wayland-based
software should work as well.
Edit a local copy of the script to make $WLD point to the
base directory where your repositories are (make sure to
use the absolute paths). You can also set the WLD
environment variable before calling the script and leave
the file untouched. Then, after executing the script, issue
the following commands to have everything built and Weston
runing from the uninstalled environment.
cd <basedir>
for i in wayland wayland-protocols libinput weston; do
cd $i && ./autogen.sh && make && cd ..; done
cd weston
weston &

+Wayland Uninstalled
+-------------------
+
+We now also include a helper script, wl_uninstalled, to build and work with an
+uninstalled wayland/weston environment comprised of the following repositories:
+
+wayland
+wayland-protocols
+libinput
+weston
+
+The wl_uninstalled script provides a shell environment in which all build and
+run run-time dependencies are resolved in such a way that the uninstalled
+versions of the above projects take precedence.
+
+Quick instructions:
+
+Let's use Weston as an example although other wayland-based projects should work
+as well.
+
+* Edit a local copy of the script to make $WLD point to the base directory
+ where your repositories are (make sure to use the absolute paths). You can
+ also set the WLD environment variable to a path of your choice and leave
+ the script untouched. Then, after executing the script, issue the following
+ commands to have everything built and weston running from the uninstalled
+ environment.

+# Based on GStreamer's gst-uninstalled (http://gstreamer.freedesktop.org/)
+#
+# This script provides a shell environment to build and use an uninstalled
+# wayland/weston setup, consisting mostly of checked out and built (no
+# "make install" required) Wayland repositories.
+#
+# Here is the list of required repositories:
+#
+# wayland git://anongit.freedesktop.org/wayland/wayland
+# wayland-protocols git://anongit.freedesktop.org/wayland/wayland-protocols
+# libinput git://anongit.freedesktop.org/wayland/libinput
+# weston git://anongit.freedesktop.org/wayland/weston
+#
+
+if [ "$1"yes != "yes" ]; then
+ cat << EOF
+
+This script uses no arguments. Aborting execution.
+
+The following parameter was not understood:
+
+"$@"
+
+Quick instructions:
+
+1.- Clone the required repositories:
+
+ wayland git://anongit.freedesktop.org/wayland/wayland
+ wayland-protocols git://anongit.freedesktop.org/wayland/wayland-protocols
+ libinput git://anongit.freedesktop.org/wayland/libinput
+ weston git://anongit.freedesktop.org/wayland/weston
+
+2.- Set the WLD variable here to point to the directory you
+ put your Wayland repositories at. Rest should remain untouched.
+ Instead of setting this variable here, you can also export it
+ before the script is executed and leave the latter untouched.
+
+3.- Execute the script. If everything goes OK, you should start
+ seeing a "[WAYLAND UNINSTALLED]" line being printed before each
+ shell prompt to remind you that you are on a wayland uninstalled
+ environment.
+
+4.- Configure and build the above projects in the order they are listed
+ in this document.
+
+5.- Run something wayland-ish, like weston, and it will use the same
+ Wayland uninstalled environment used to build.
+
+6.- To exit the Wayland uninstalled shell just use the 'exit' command.
+
+EOF
+ exit -1
