Hi, first of all, thanks for such a wonderful package. There is no official release on Indigo, but I'm using it thanks to #12. And second, the issue title is not entirely correct, let me explain.
I have Ubuntu 14.04/Indigo on two machines, I git clone
the same code (decision_making
package included), and I can see all examples in both PCs.
But my example can only be rqt-graph-viewed on one of them, in the other, the rqt_decision_graph
plugin crashes with the log I paste below.
I've been trying to figure out what could be the difference, but can't spot it. I also found that several persons have had the trouble in init_rank
with graphviz, but not sure this is the case.
Any idea what it could be?

Hello,
During testing of your stack, the Roomba example didn't work. I also tried to implement my own state machine with two states using FSM_ON_CONDITION condition function, but the state didn't change (same as for Roomba example). On other hand other examples work, but they are all using FSM_ON_EVENT function, so currently I am using it also and works just as expected.
I am using Ubuntu 12.04.4 with Hydro (updated version).
Do you have any plans to release this a s a catkin package on ros buildfarm for indigo and above?
Thanks in advance.
I am trying to run the FSM faster by reducing the sleep duration to 10ms, the state machine is runing ok but the rqt pluggin keeps crashing (after a few secs of running)
there are 3 types of error I usually see.
Error in python: double free or corruption (fasttop): 0x00007fb810003df0
Aborted
(or)
Segmentation fault
(or)
Error in `python': realloc(): invalid pointer: 0x00007f869826c840
Code for DualTask FSM example is missing in your public git repository.
Thank you for the tutorials!
Launch any of the fsm examples opens rqt window.
The Graph.py is looking for a non existing dot file.
Anyway, the application doesn't produce dot file.

All the examples I saw were in C++. Is there a python compatibility? The alternative is to use a C++ state machine with the ROS topic\service\action interface to speak to the other nodes being co-ordinated... I'm trying to stay away from that and use the state machine entirely if possible.
Hi,
Trying to go through Decision Making tutorials, I tried to run the rqt_decision_graph.
I followed the http://wiki.ros.org/decision_making/Tutorials/Runtime section 1.4 meaning run "rqt" and then tried to load the plugin "Decision Graph Plugin"
and got:
michele@darpaws5:~/testing/hydro/catkin_ws/devel/bin$ rqt
