catkin_make error when install plugin

[onlytailei]

Hi, I use Ubuntu 12.04 and Hydro-ros

After the installing of vrep and downloading the vre_ros_pkg, when I catkin_make the catkin_ws, I got this:

In terminal:

CMake Warning (dev) at /opt/ros/hydro/share/roslib/cmake/roslibConfig.cmake:165 (find_package):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy

  warning.

  Quoted variables like "include" will no longer be dereferenced when the
  policy is set to NEW.  Since the policy is not set the OLD behavior will be
  used.

As explained in https://github.com/lagadic/vrep_ros_bridge/blob/master/README.md it seems to me that you forgot to:

export VREP_ROOT_DIR=/ChangeWithyourPathToVrep/

in the terminal where you run catkin_make

[fabrizioschiano]

I wanted just to add that you can avoid entering always the export command mentioned by fspindle by putting that command in your bashrc file. In this way the command will be run every time you open a terminal.

To do that, in a terminal you can do: cd gedit .bashrc

Then you can paste in your bashrc file: export VREP_ROOT_DIR=/ChangeWithyourPathToVrep/

For me is something like that: export VREP_ROOT_DIR=/home/fschiano/V-REP_PRO_EDU_V3_2_1_64_Linux

Of course you need to change the previous command according to your path.

fabrizioschiano and fsindle, thanks for you replies. I'm sure I have done that. And when I echo $VREP_ROOT_DIR in that terminal, I got the right path. So what should I do?

[fspindle]

In the same terminal run the following commands and give us the full output:

$ ls $VREP_ROOT_DIR/vrep.sh
/home/fspindle/soft/vrep/V-REP_PRO_EDU_V3_2_2_64_Linux/vrep.sh

$ cd ~/catkin_ws/src/vrep_ros_bridge
$ git checkout hydro-devel

$ cd ~/catkin_ws
$ catkin_make --pkg vrep_ros_bridge --cmake-args -DCMAKE_BUILD_TYPE=RelWithDebInfo

[onlytailei]

$ ls $VREP_ROOT_DIR/vrep.sh
/home/tyler/Software/V-REP_PRO_EDU_V3_2_2_64_Linux/vrep.sh

$ cd ~/catkin_ws/src/vrep_ros_bridge
$ git checkout hydro-devel
Already on 'hydro-devel'

$ cd ~/catkin_ws
$ catkin_make --pkg vrep_ros_bridge --cmake-args -DCMAKE_BUILD_TYPE=RelWithDebInfo

still the same error

[fspindle]

Yesterday we introduced changes in hydro-devel branch. Do a git pull, remove build an devel folders and try a new build

[jokla]

Also try to build the first time just with a simple catkin_make cd ~/catkin_ws $ catkin_make
