I just released ARToolkitPlus 2.1.3 based on the new development on launchpad. While the last official release 2.1.1 was back in 2006 and the intermediate release 2.1.2 just contained some build fixes, this version is actually useful.
It has the following features/ fixes:
- build fixes with GCC 4.4
- allow build with -std=c++0x
- allow system-wide installation (allows packaging)
- add debian packaging information
therefore you can find some ARToolkitPlus packages in my PPA now.
In case you wonder about the differences between ARToolkit and ARToolkitPlus or you are searching for more documentation, I also set up an FAQ.
