Installing WebUI with proper Environmental Variables

Question

I'm trying to install the web interface on my laptop. I've gotten things to work after a little tweaking (which I updated on the wiki), so that I get through the whole installation process.

However, when I open a browser, I get this error message.

MOD_PYTHON ERROR

ProcessId: 6630 Interpreter: '127.0.0.1'

ServerName: '127.0.0.1' DocumentRoot: '/var/www'

URI: '/webui/' Location: '/webui/' Directory: None Filename: '/var/www/webui' PathInfo: '/'

Phase: 'PythonHandler' Handler: 'startmod'

Traceback (most recent call last):

File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1537, in HandlerDispatch default=default_handler, arg=req, silent=hlist.silent)

File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1229, in _process_target result = _execute_target(config, req, object, arg)

File "/usr/lib/python2.6/dist-packages/mod_python/importer.py", line 1128, in _execute_target result = object(arg)

File "/opt/ros/diamondback/stacks/web_interface/webui/src/webui/startmod.py", line 18, in handler ros_root = os.environ['ROS_ROOT']

File "/usr/lib/python2.6/UserDict.py", line 22, in getitem raise KeyError(key)

KeyError: 'ROS_ROOT'

Clearly, ROS_ROOT is not being set properly. Any ideas where to set this variable so that the Webui picks up on it? Currently, I believe it is being set through setup.bash.

Stopping apache and then relaunching the webui fixed the problem.
