Description
Hello there,
I would like to create some OSG visualisation. It seems that the required OSG version is 3.5.6 according to release notes. This version seems kind of outdated as is not even offer at: http://www.openscenegraph.com/index.php/download-section/stable-releases . Do you consider upgrade to a newer version e.g. 3.6.5 or can we already use the new version?
B.R.
Petr
Solution:
an OSG upgrade is unfortunately impossible for good. OSG does not retain ABI compatibility cross version, so this would would break all existing visualization implementations.
In fact, OSG does not even guarantee ABI stability within a single release based on the specific configuration chose, so you must link against https://artifactory.digitalwerk.net/ui/repos/tree/General/dw-developer-sdk/dw/osg/3.5.6/stable and not whatever other version you might be able to obtain from upstream sources.
However, since OSG as a whole is pretty much abandon ware (and even 3.6.5 was just a development-snapshot in middle of some ongoing refactoring refactoring), there isn't much lost or gained in stability or features from sticking to 3.5.6 anyway.
