Got a build error on my Macbook w/ Mac OS 10.5.7 for bullet-2.75-beta1. Version 2.74 built ok. Here is the error:

Both CMake and jam should build fine on all platforms (and so do visual studio projectfiles on Windows).

Are you using autotools/automake (./autogen.sh, ./configure, make)? Autotools/make doesn't seem to be actively maintained. It is likely a matter of adding a few files to one of the Makefile.am files (check Bullet/src/BulletDynamics folder. The missing files seems to be from the constraint solver in ConstraintSolver.

If you get it to work, can you please submit a patch in the tracker?
Thanks,
Erwin

At your suggestion, I looked for and added new files in Bullet/src/BulletDynamics to the src/Makefile.am and that fixed the problem. Patch is submitted in Issue 226 in the tracker.
