Setting up python2.5 for Massive Prime

Python can be used in Massive by typing commands directly in the textport and from scripts. The textport is accessed from the Options menu. Scripts can be run from the textport using the execfile() function and from the commandline using the -script commandline option.

Three versions of python are supported by massive ver<4.0, Python1.5, Python2.2, and Python2.5. For ver<4.0 Python2.5 is selected by default while starting massive. You can  specify a particular version of Python by entering one of the following in the textport

 #!pyscript15
 #!pyscript22
 #!pyscript25
 

openSUSE 11.3 comes with pre-installed Python2.6.5. Hence in case you want to use Python2.5 with massive you need to install Python2.5 can be downloaded from here. Massive will need the shared library for python to be in the $PYTHONHOME in order to support the specific python version. If you are building python yourself, you can get that done by specifying

./configure   –enable-shared   –prefix=/usr

I missed that step while building and I didn’t wanted to build it all over again. Instead found a workaround for the same. Since I had Foundry Nuke installed on my machine, which comes with a shared library for Python2.5 (libpython2.5.so.1.0), it was just a matter of creating a symlink to the shared library path on /usr/lib64 for libpython2.5.so.1.0

ln -s   /usr/local/nukeVersion/libpython2.5.so.1.0   libpython.2.5.so.1.0

If these operations have been successful, you will be able to access Python2.5 modules within massive.Else you will be getting an error echoed in the console like this

libpython2.5.so.1.0: cannot open shared object file: No such file or directory

Installing Massive Prime on openSUSE 11.3

Massive is the premier simulation and visualization solution system for generating and visualizing realistic crowd behaviors and autonomous agent driven animation for a variety of industries, including film, games, television, architecture, transportation, engineering, and robotics. Using Massive, an animator, engineer or robot developer designs characters with a set of actions and reactions to what is going on around them.

The installation manual that comes along with massive is sufficient for a noob to get massive running on your machine. But if you are planning to run massive on a Linux machine, you better go through the Troubleshooting section too. Even after getting the mhost server running you may still get an error “could not open connection” while executing massive from the shell. If u are using Fedora, you will be happy to see the following section under the Troubleshooting section

I am on Fedora and get a “could not open connection” error message when trying to start Massive.

The “could not open connection” error you’re getting is because the X server on Fedora has TCP connections disabled by default. Massive is trying to connect to the X server over TCP and failing. If you add the following line to the [security] section of your /etc/X11/gdm/gdm.conf it should remedy the problem.

DisallowTCP=false

But under openSUSE running on KDE, you wont find a gdm installation at all. Hence in order to enable TCP/IP sockets for X11, you need to follow the instructions below.

  • Set DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN=”yes” in the /etc/sysconfig/displaymanager file
  • Running /sbin/SuSEconfig to propagate that setting
  • Restart your display manager through /usr/sbin/rcxdm restart
