Hi Cohen,

It not worked with me, I can find the example_topic that list in the rostopic but the rostopic echo shows nothing and I got an error when execute example_publisher.m in Matlab

Warning: Directory access failure: /bin/bash.

??? Undefined function or method 'geometry_msgs_Twist' for input arguments of type 'char'.

Error in ==> example_publisher at 13
pid=geometry_msgs_Twist('connect','publisher','example_module','twist');

Thanks for any help.

Best,

Nikos,

Actually, that part of the tutorial is outdated. No bin folders should have been created in those folders. The bin folders should only be created in the ipc_[...]_msgs folders such as  ipc_msgs/ipc_geometry_msgs/.

I'll update the tutorial. Have you tried the example publisher/subscriber?

Hello all

I tried to install the interoperability system between Matlab and Ros. 
(https://alliance.seas.upenn.edu/~meam620/wiki/index.php?n=Roslab.IpcBridge)

I followed the instructions and the compilation of the packages produced no error.
According to the instructions, bin folders should have been created e.g.
ipc_bridge_ros/bin
ipc_bridge_matlab/bin

but are actually missing.
Has anyone experienced something similar?

Thanks
Nikos
