test if the installation was succesfull !

[DOUNIA11]

Hi
I'm using ubuntu 14.04 and ROS indigo, I installed V-REP_PRO_EDU_V3_4_0_Linux, then I followed all the instructions of V-Rep ROS Bridge installations except the instruction :
ln -s /YOUR_CATKIN_WS_PATH/devel/lib/libv_repExtRosBridge.so
it doesn't work for me
so I used :
ln -s /YOUR_CATKIN_WS_PATH/devel/lib/libv_repExtRosBridge.so/*
I completed the full instructions, but when I try to test the installation if it works , I run roscore and Vrep I will get this:
Add-on script 'vrepAddOnScript-addOnScriptDemo.lua' was loaded.
