panda3d/doc/build

#!/bin/bash

# This script is an experiment.  It is designed to automate the
# Panda3D build process for Linux or Unix users, or for Windows users
# who have Cygwin installed.  If you want to build Panda3D on a
# Windows machine without Cygwin, please refer to the INSTALL document
# instead of attempting to run this script.

# Before you run this script, you must set up your Config.pp file and
# Config.prc files as described in the INSTALL document, and you must
# build and install ppremake (or ppremake.exe), before running this
# script.  

# You should ensure that the install bin directory,
# e.g. /usr/local/panda/bin, is on your PATH, and that the install lib
# directory, /usr/local/panda/lib, is on your LD_LIBRARY_PATH (for
# Unix) or your PATH (for Windows).  If you are building Python
# interfaces, you should also ensure that /usr/local/panda/lib is on
# your PYTHONPATH.

# Finally, you must have write permission to the /usr/local/panda
# directory hierarchy in order for this script to run successfully.

# As with any automatic process, this script may not work in every
# environment.  An effort has been made to make the script as
# trouble-free as possible, but things can always go wrong.  If you
# have difficulty running this script, you are encouraged to follow
# the step-by-step instructions in the INSTALL document to build
# Panda3D by hand.
