Installing and running on x86-64

This is what I have managed to gather about running OpenSimulator on an Intel Core2 on a 64bit linux system. To install it you need to do:

 svn co http://opensimulator.org/svn/opensim/trunk opensim
 cd opensim
 sh runprebuild.sh
 nant
 cd ..
 svn co svn://openmetaverse.org/libsl/trunk libsl
 cd libsl/openjpeg-libsl/
 nano Makefile (add -m64 to compile flags to avoid another segfault)
 make
 cp libopenjpeg-libsl-2.1.2.0.so ../../opensim/bin/libopenjpeg-libsl-2.1.2.0-x86_64.so
 cd ../../opensim/bin/
 cp OpenSim.ini.example OpenSim.ini
 mono OpenSimulator.exe

Unfortunately this results in a segmentation fault. Which is somewhat remedied by building the libsl libraries by hand and copying the dll's from the freshly built libsl to the OpenSimulator bin/ folder. This makes us get one step further. Unfortunately (Again) at this point we get other problems as apparently OpenSim is not compatible with the new libsl. I am yet to find a solution to this.

A bug has been filed on this: http://opensimulator.org/mantis/view.php?id=43

I found deleting bin/libopenjpeg-1*so 'fixed' this problem for me (breaks terrain but the sim starts) - I guess that the svn-bundled openjpeg lib is out of date for x86-64 -- mggrant.

As of early Dec, opensim has been updated to match libsl 1498 and rebuilding that version of the openjpeg library in 64 bit now works -- mggrant.
