<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">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.<o:p></o:p></span></p>

This other engine is turned on in your INI file by selecting the BulletSim physics engine and then specifying the XNA Bullet implementation:<o:p></o:p></span></p>

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.</span><o:p></o:p></p>
