pybullet/vehicles revision 39 doesn't compile

Are you talking about the vehicles branch? "pybullet/vehicles" seems to suggest that, but I'm not quite sure. If so, then I'm not really trying to maintain the vehicles branch as working code. It's a big, big pile of functionality that sastraxi contributed all at once, most of which I don't understand. I'm keeping the branch as a place to grab code from, gradually, as I find time to understand and test it.

Feel free to try to fix it, but if you'd like to help move the project forward, it would be more useful to find individual features that it implements and pull them out into separate branches, adding unit tests and documentation. A self-contained branch that documents, tests, and implements a single feature is a lot easier for me to look at and merge into trunk.

Thanks!

Yes, I was talking about the vehicles branch. I'm working on a simulation project (trying to recreate Karl Sims' virtual creatures work using Python), and my team needs to use constraints as joints between body parts.

We would like to contribute to pybullet if we can, but our primary objective is to get the physics portion of the project implemented as quickly as possible so that we can focus on writing the neural network and genetic algorithm part of the project.

At the moment, our options are
1) modify trunk to add the basic hinge and point constraints we need
2) fix rev 39 of the vehicles branch
3) modify rev 38 of the vehicles branch to support debug mode
and
4) switch to a 2d physics library like pymunk (which is less exciting)

Please let me know if you have any advice for moving forward with this; we would really like to use pybullet if possible, and we will be sure to make any improvements we make available on Launchpad.

I managed to pull in most of the changes in trunk by manually merging it with revision 38, even though I still don't really know much about Pyrex.

My biggest concern is with btOverlappingPairCache, because both trunk and rev 38 of the vehicles branch implemented different parts of it, and when I attempted to combine them, bullet.pyx stopped compiling again.

Right now, most of the demos and test files seem to work in a way similar to those in trunk.
