If you're upgrading libopenmetaverse, make sure you read Upgrading Libopenmetaverse for RESTbot first.

Under Linux/Mac OS X:

If not, you might need to prebuild libopenmetaverse the first time you run it. Go to the libopenmetaverse directory first and do ./runprebuild.sh nant. This should pre-generate the necessary build files.

Then you can go to the root of your installation and run nant which should compile everything.

The actual grid configuration parameters are on ./restbot-bin/configuration.xml. Just change what is between

<loginuri>https://login.agni.lindenlab.com/cgi-bin/login.cgi</loginuri>

to the URL login setting for your own grid.

Currently, one RESTbot can only connect to a single grid. But you can launch several different RESTbots on the same server, at different ports, one per different grid, if you wish.
