The BulletSim build process is to generate static Bullet libraries and then
statically link these to create the BulletSim DLL/SO. The CMake parameters I
use are “-DBUILD_EXTRAS=on –DBUILD_DEMOS=off –DINSTALL_LIBS=on
–DINSTALL_EXTRA_LIBS=on –DBUILD_SHARED_LIBS=off –DCMAKE_BUILD_TYPE=Release”.[1]
The shared library build is ‘off’ to generate the ‘.a’ libraries to statically
link with BulletSim.
If you come up with a similar build process for osx, I would like to add that
to the BulletSim documentation so, when you are successful, please share the
process.
A totally different approach would be to use the Bullet implementation that is
all C#. This requires no machine dependent libraries at the cost of some
performance. This other engine is turned on in your INI file by selecting the
BulletSim physics engine and then specifying the XNA Bullet implementation:
[Startup]
physics = BulletSim
[BulletSim]
BulletEngine = “bulletxna”

Subject: [Opensim-dev] Running BulletSim on osx
Does anyone know what steps are needed to get this working?
I've been trying to enable BulletSim physics for osx. The dylibs aren't in git
- so it doesn't work out of the box, but I've been playing around this evening
trying to get this running on my mac.
I've managed to get the opensim-libs cmake working for osx lion (at least I
think I have - cmake -DBUILD_SHARED_LIBS=ON -DFRAMEWORK=ON etc, gives me a
bunch of promising looking shared libraries) and I've found the code that tells
the bullet Physics config how to look for the appropriate dylib in lib/lib32,
so I can fix that up as well.
However, nothing called libBulletSim.dylib seems to get built by the cmake
files in opensim-libs, so I'm a bit confused as to what binaries I would need
to copy into the opensim lib folder in order to make bulletsim happy.
Do I simply rename libbulletcollision or libbulletdynamics to libBulletSim, or
is it a bit more involved than that?
Thanks
jonc
