Modifying Open Source Code

The Polycom RealPresence DMA system software is not combined with or otherwise linked to any open source libraries, but the CentOS software is. The LGPL v2.1 license allows you to modify the LGPL code included with CentOS, recompile the modified code, and re-link it with the CentOS code. Note that although you’re free to modify the included LGPL modules in any way you wish, we cannot be responsible if the changes you make impair the system.

To replace an LGPL library with your modified version

1Obtain the source code for the module you want to modify.

2Modify the source code and compile it.

3Go to Admin > Local Cluster > Security Settings, select Allow Linux console access, and click Update.

4Contact Polycom Global Services for the root password for the Polycom RealPresence DMA server.

5Use ssh to log into the server as root.

6Upload the modified software via wget or scp.

7Find the module you’re replacing and install the new version to that location.

8Reboot the system.
