Subversion

Opal uses Subversion for project file version control. The repository is hosted by SourceForge

The repository can be browsed here

Anonymous downloads from the SVN repository are possible using a number of popular clients:

• The "svn" command is provided as part of most Unix distributions. SourceForge provides an excellent introduction to the svn command
• On Windows, the TortoiseSVN client provides excellent integration with the Windows explorer

The top level URL for the repository is:

The top level modules are opal and ptlib. The trunk revision of these modules (which is also the development revision) can be extracted using the following commands:

The current development version is always in the trunk. There may be snapshots of development versions though this is rare.

To extract a stable branch of OPAL and PTLib, use the following commands

where vA_B is the current version e.g. PTLib version 2.2.x would be v2_2, similarly vC_D for OPAL version 3.2.x would be v3_2. For example:

To extract a formal stable release of OPAL and PTLib, use the following commands

where vA_B_C is the current version e.g. PTLib version 2.8.3 would be v2_8_3, similarly vC_D_E for OPAL version 3.8.3 would be v3_8_3. For example:

The SVN trunk has odd version numbers and stable revisions are always in branches with even numbers. The development trunk will also be marked as "alpha" when you get version numbers strings from the libraries. The even numbered stable branch are marked as "beta". Only the formally released tar balls, and their associated "tagged" SVN versions do not have "alpha" or "beta" associated with them.

See the Wiki page on Version Numbering for more information on the versions available.
