[Opensim-users] 0.7.6 and MONO 3 (OS X)

[Justin Clark-Casey]

OpenSimulator 0.7.6 should have run just fine with Mono 2.4.3.  However, I'm beginning to think that I made a mistake 
when building it.  It should run under Mono 2.4.3 if you took the source code and recompiled it with Mono 2.4.3 
yourself, though I would recommend using later Mono instead if at all possible.

I hadn't heard of that finalizer thread issue with Mono 2.10, at least on Linux.  I can imagine Mac is significantly 
different in this area though, so possibly this is a Mac only issue.

I have heard of people (plus yourself now) running OpenSimulator with Mono 3 (at least later than 3.0.6) with good 
results, so this should be a viable route.

I believe Mono 2.8 should also run .NET 4 code.  However, I wouldn't recommend 2.8 since there were many issues with it 
in the past.  I put Mono 2.10.8.1 as the minimum firstly because it's the one shipping on all the latest major distros, 
and secondly because somewhere in the 2.10.* releases (2.10.5 perhaps), a bug was resolved which would cause the 
OpenSimulator sun to jump around unexpectedly.
