makepanda fails with bullet 2.81

Ich_und_nicht_du · August 18, 2013, 5:54pm

I tried to compile panda3d using makepanda on Linux Mint Debian with the following command:

makepanda/makepanda.py --installer --nothing --use-python --use-zlib --use-png --use-openal --use-pandatool --use-direct --use-gl --use-bullet --use-x11 --threads 2

I need bullet and because i didn’t find it as a DEB i downloaded the version 2.81 from bulletphysics.com. Makepanda doesn’t give a warning about not finding something so it should find bullet. It’s installed in /usr/local/lib. See:

$ ls /usr/local/lib
libBulletCollision.so       libBulletSoftBody.so       pkgconfig  site_ruby
libBulletCollision.so.2.81  libBulletSoftBody.so.2.81  python2.6
libBulletDynamics.so        libLinearMath.so           python2.7
libBulletDynamics.so.2.81   libLinearMath.so.2.81      python3.2

But i get the following error which seems to be related to bullet:

Since i’m not really into C/C++ i can’t say for sure what this error means. It seems related to bullet. Can anyone tell me what’s wrong?

enn0x · August 19, 2013, 10:26am

Which version of the Panda3D source code did you try to compile? A release version, or current CVS HEAD (with date please)?

Ich_und_nicht_du · August 19, 2013, 10:57am

Sorry that i forgot to write that.
I’m building version 1.8.1.

enn0x · August 19, 2013, 3:36pm

This is the current release branch. You need to use Bullet 2.80, because of API changes between Bullet 2.80 and 2.81 which would lead to API changed in the Pand3D Bullet API. Since Panda3D enforces ABI compatibility on major releases (1.8.x), we can’t do these modification on the release branch:

Bullet 2.81 has been released Oct 2012
Panda3D 1.8.0 has been released Feb 2012 (older!)

So either use Panda3D 1.8.1 (release) and Bullet 2.80, or current Panda3D snapshot and Bullet 2.81.

For more details please see: Panda Bullet

Ich_und_nicht_du · August 19, 2013, 6:07pm

I now installed bullet 2.80-rev2531 and tried to build panda3d 1.8.1.
I also removed the --use-zlib from the command line to enforce a new build.
I now get this error:

/btCollisionWorld.h:429:20: note:    virtual btScalar btCollisionWorld::ContactResultCallback::addSingleResult(btManifoldPoint&, const btCollisionObjectWrapper*, int, int, const btCollisionObjectWrapper*, int, int)

I still see the Bullet 2.81 signatur for the contact result callback. In Bullet 2.80 there has been no “btCollisionObjectWrapper”, and the argument have not been “const”.

Either you failed at replacing Bullet-2.81 with 2.80 (and you still have 2.81 somewhere around), or you did not clean up the Panda3D built directory.

I don’t know about Linux, but on Windows it is NOT enough to simply modify you build parameters - you have to delete the “built” directory and do a new, clean build.

Ich_und_nicht_du · August 19, 2013, 7:28pm

Sorry for the last post. A few minutes after posting i realised that i forgot to install bullet after compiling. But i hadn’t time to edit the post. I finished the build right now. Thanks for your help.

enn0x · August 20, 2013, 7:00am

You’re welcome. If you intend to use Bullet I would recommend using Panda3D CVS & Bullet 2.81. There have been many improvements and bugfixes, both in Bullet 2.80 to 2.81 and in Panda3D’s Bullet module since the 1.8.0 release. And the Panda3D CVS can be assumed to be nearly as stable as the release versions.

Ich_und_nicht_du · August 20, 2013, 3:24pm

Thanks. I will consider you suggestion. Using the CVS version might be a good idea.
