# this script is in CVS as gstreamer/docs/faq/gst-uninstalled
|
|
#
|
|
# It will set up the environment to use and develop gstreamer and projects
|
|
# that use gstreamer with an uninstalled CVS checkout of gstreamer and the
|
|
# plugin modules.
|
|
#
|
|
# It will set up LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, PKG_CONFIG_PATH,
|
|
# GST_PLUGIN_PATH, GST_PLUGIN_SYSTEM_PATH, GST_REGISTRY, MANPATH, PYTHONPATH
|
|
# to prefer the uninstalled versions but also contain the installed ones.
|
|
# The only exception to this is, that no system installed plugins will be
|
|
# used but only the uninstalled ones.
|
|
#
|
|
# This script assumes that the relevant modules are checked out one by one
|
|
# under a given tree specified below in MYGST.
|
|
#
|
|
# Symlink this script in a directory in your path (for example $HOME/bin). You
|
|
# must name the symlink gst-something, where something is the subdirectory
|
|
# of MYGST that contains your gstreamer module checkouts.
|
|
#
|
|
# e.g.:
|
|
# - mkdir $HOME/gst/head
|
|
# - ln -sf gst-uninstalled $HOME/bin/gst-head
|
|
# - checkout copies of gstreamer modules in $HOME/gst/head
|
|
# - gst-head
|
|
|
|
# This script is run -i so that PS1 doesn't get cleared
|
|
|
|
# Change this variable to the location of your gstreamer CVS checkouts
|
