[Opensim-users] Opensim of 64 bit Linux servers

[Snoopy Pfeffer]

I saw that the 64 bit installation instructions on http://opensimulator.org/ are not up-to-date anymore.

I have installed opensim #7731 with ODE on a 64 bit ubuntu 8.10 server by doing the following steps:

1. I have installed Mono 2.3 as described here:
   http://osgrid.org/forums/viewtopic.php?f=14&t=475
   Mono 2.3 is required to avoid startup problems with newer opensim versions.

2. I have downloaded and installed the lastest SVN version of opensim as usual (like a 32 bit system):
   http://opensimulator.org/wiki/Build_Instructions

3. I have downloaded and installed the Open Dynamics Engine (ODE) to replace the 32 bit version of ODE with a 64 bit version. I did that with the following linux commands (it is expected that you have all required Linux building tools installed):
   > svn co http://opensimulator.org/svn/opensim-libs/trunk/unmanaged/OpenDynamicsEngine
   > cd OpenDynamicEngine
   > chmod a+x ou/bootstrap
   > sh autogen.sh
   > CFLAGS="-m64" ./configure --enable-shared
   > make
   > cp ./ode/src/.libs/libode.so ../opensim/bin/
   > vi ../opensim/bin/OpenSim.ini  (change av_capsule_standup_tensor_linux to 1700000)
   The 'chmod' command is required to fix permissions that are wrong. The change in OpenSim.ini is required to avoid that avatars have bend legs and/or their feet are in the ground.

I use this installation since about 2 weeks with ODE, Meshmerizer and XEngine and it works reliable, although 64 bit installations of opensim are not officially supported at the moment.
