* important bugfix, please upgrade from 2.44 to 2.45

You can download new source release of the Bullet Physics 2.45.

Due to incompatibility and alignment issues, Bullet doesn't use STL anymore.

- std::vector is replaced by btAlignedObjectArray. This array container has also a heapsort and binary search (both in-place), and is mostly compatible with std::vector, except no iterators.
- fixed 'wrong cast' and 'missing symbol gUseEpa'.
- The SAP only adds objects, never removed. Removal is postponed for during traversal of overlapping pairs (duplicates and non-overlapping pairs are removed during that traversal).

- from 2.44 to 2.45 the island (constraint) sorting has been fixed, thanks Clemens Unterkofler for reporting!

Enjoy,
Erwin

Thanks Erwin!! that was a great move on the Bullet development. Now it is more stable and compatible with multiple plattforms.

Great news to get rid of STL. I've seen only troubles with it so far.

Trying to build this ( I know, took me some time, had other things to do ) fails on autogen.sh, reason:

Code: Select all

configure.ac:72: error: possibly undefined macro: _AC_SRCPATHS
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

Fix: Comment out line 72 in configure.ac

Not sure what this line does as I've never used it in a configure myself.
