Details

In the current version of Blender package (2.48a-2): the wrong option is being used to enable bullet physics engine and thus the engine is left disabled.

Steps to fix:

PKGBUILD
-export WITH_BULLET=1
+export WITH_BF_BULLET=1

At least I hope so, still compiling... but I've noticed the bullet code being built in the output from the makepkg.
This task depends upon

try to export WITH_BF_GAMEENGINE=1 also

that's pretty weird. I swear, during the build a bullet2 directory exists and is filled with bullet.la
As for the Game engine, a blenderplayer library is build and comes with the package. It needs the game engine.

hint, hint: http://lists.blender.org/pipermail/bf-blender-cvs/2008-December/017110.html

But this fixes the scons build. PKGBUILD uses make and obviously this patch will not help.

I just found out that it works if you use cmake and then make...

At first I build the ABS PKGBUILD and the just went into the build directory and then "cmake ../blender-2.48a && make" and it works now

I don't see the issue.
blender 2.48a-2 is definitely compiled with bullet, both blender and blenderplayer. I just tested with my bge projects that don't work with the deprecated physics engine sumo.
Arch Linux blender is compiled with the make method: WITH_BF_BULLET is the flag for enabling bullet when building with scons.
I'm going to request a closure.

Same Problem here.
Pysik doen't work right.

Try to make a cloth simulation and you will see it.

I see now; but note that the other panels work. Also you can see in the World buttons that bullett is enabled.
So the problem is only (at least I think so) in cloth dynamics.
And @PyCoder, no one before you pointed at this issue in the current task.

Sorry i didn't mean all physic's.

Only collsion from cloth doesn't work and that shows Ondrej Jirman in his Pic (xxx.png).

I hope someone can fix it. :)

Could you please confirm that replacing
export WITH_BULLET=true
with
NAN_USE_BULLET=true
in the PKGBUILD and rebuilding the package makes cloth dynamics work?
Comment by Alessandro Doro (adoroo) - Tuesday, 07 April 2009, 00:49 GMT
Sorry:
export NAN_USE_BULLET=true
Comment by F.Di Milia (PyCoder) - Tuesday, 07 April 2009, 14:26 GMT
Now cloth dynamics works with export NAN_USE_BULLET=true.


Thx :)

I requested a closure because the bug report was incomplete/malformed. Anyway the bug is valid, see the last comments. Indeed a wrong flag is specified in the PKGBUILD.
Comment by F.Di Milia (PyCoder) - Tuesday, 12 May 2009, 21:09 GMT
Could the Maintainer please update the package? :)
Comment by Alessandro Doro (adoroo) - Saturday, 30 May 2009, 18:36 GMT
2.49. Fixed upstream; now NAN_USE_BULLET is exported in source/nan_definitions.mk
