#
# 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.
