[Opensim-dev] [libsl-dev] how does libopenmv handle different versions of the same packets?

[John Hurliman]

I'm not able to reproduce this with the trunk of libomv, I believe it was
fixed a long time ago. With a 1.20 release candidate viewer I will correctly
get an ObjectGrabPacket object with a SurfaceInfoBlock array of zero length.
If I connect with a 1.21 client I get a SurfaceInfoBlock array with length
one and all of the fields filled in. Sounds like the solution is for libomv
to get the 0.6.0 release pushed out (alongside the 1.0.0 release of
OpenMetaverseTypes), and me to finish the upgrade patch for OpenSim.
