What's wrong?

[IN-Gamut]

I have the same problem. What is the problem?
My bullet version is 2.84, the newest one.

[karlsvec]

The Bullet developers have made many incompatible API changes throughout the 2.8x releases, and unfortunately, osgBullet will not build against the latest Bullet release.

The most recent Bullet version that osgBullet is known to build against is the 2.80-r2531 "snapshot" release from Google Code:

[IN-Gamut]

By turning off the OSGBULLET_BUILD_EXAMPLES flag will pass the compilation
