RosInterface Loading Error

Postby olivia » 24 Oct 2016, 07:59

I installed VREP version 3.3.2 edu and indigo on Ubuntu 14.04 and was trying to interface between the two.
After compiling the plugins as in http://www.coppeliarobotics.com/helpFil ... Indigo.htm using catkin tool(there were some bugs "can't find .h .cpp files", so I copied those files from vrep/programming/common and build the workspace successfully), I copied libv_repExtRosInterface.so file to V-rep installation directory and opened roscore then start v-rep.
The following error appears.
--------------------------------------------------------------------------------
Plugin 'RosInterface': loading...
[FATAL] [1477291636.529911605]: ROS_MASTER_URI is not defined in the environment. Either type the following or (preferrably) add this to your ~/.bashrc file in order set up your local machine as a ROS master:

export ROS_MASTER_URI=http://localhost:11311

then, type 'roscore' in another shell to actually launch the master program.
------------------------------------------------------------------------------------------------------------------
I tried
1. copy exactly that line into .bashrc, reopen terminal and run roscore and start vrep, but the same error appears. if I type
echo $ROS_MASTER_URI, output is http://localhost:11311/, which I guess is to be expected.
2. type that line in the terminal and start vrep again, same error appears.


I am new to ROS and VREP so I don't know what happened. Any help is appreciated! Thanks.



=============
update:
reinstalled ROS and tried starting vrep, it was smooth for the first time. But after I quitted vrep and started again, the same error appeared..

updateupdate:
run vrep without sudo would work
