[Robotics] Blender Ubuntu 9.10 iTaSC branch build -> fail

[Florian Lier]

Hmmm,

ok - checked out the latest src, seemed to compile, then I got the 
following error:

source/blender/blenkernel/intern/node.c:31:20: Fehler: Python.h: No such 
file or directory
scons: *** 
[/home/fl0/BlenderITASK/build/linux2/source/blender/blenkernel/intern/node.o] 
Error 1
scons: building terminated because of errors.

I've used the following commands as described in the Blender wiki, I 
although installed all deps:

cd ~ ; \
mkdir blender-svn ; \
cd blender-svn ; \
svn checkout https://svn.blender.org/svnroot/bf-blender/trunk/blender blender; \
cd blender; \
echo "BF_OPENAL_LIB = 'openal alut'" > user-config.py; \
python scons/scons.py;


Is there any other approach?


Second question:

Benoit said that I won't be possible to use the gameEngine and compute the 
joint angles ... BUT what about the way I'm doing it now - just move the robots'
model in the 3D view and run a script?


Thanks in advance - Florian
