Running into issues while building ros_packages

[kleinash]

Hi, I am trying to link my workspace with V-REP and am running into an install issue.


This is the tail of output while running catkin_make.

Code: Select all

  Must remake target 'vrep_common_generate_messages_cpp'.
  Successfully remade target file 'vrep_common_generate_messages_cpp'.

Where can I start looking for the issue? Which package is this looking for?

Thx

Please bear with me as I problem solve.

I deleted my build/ folder and started again and now I get this error:

Code: Select all

Now I really am stuck.

When I run ./vrep.sh I get this error:

libv_repExtRos.so: undefined symbol: _ZN3ros4initERiPPcRKSsj

and when I do a check by running ./libLoadErrorCheck.sh:

V-REP_PRO_EDU_V3_3_1_64_Linux/libLoadErrorCheck
./libLoadErrorCheck.sh: 21: ./libLoadErrorCheck.sh: /home/ashley/V-REP_PRO_EDU_V3_3_1_64_Linux/libLoadErrorCheck: not found

Hello Ashley,

have a look at this post. This post contains a script that can be used to recompile the whole thing, which is not needed if you didn't modify the source code.

Since last release, you should really use the catking build tools (and not catkin_make). Always make sure that your ROS environment is correctly configured and initialized. Also, as you mentioned it, it sometimes helps already to completely clear the workspace.

In the V-REP folder there is another folder that contains the precompiled ROS libraries. You should be able to simply copy them into the V-REP folder, without compilation.

If you didn't modify the packages source code, but you want to recompile them, then you could simply do:

Code: Select all

source /opt/ros/indigo/setup.bash ** or source /opt/ros/jade/setup.bash, etc. **
rm -r -f ~/catkin_ws/*
mkdir ~/catkin_ws/src
cd ~/catkin_ws/src
catkin_init_workspace
cd ..
catkin_make
source devel/setup.bash
** copy v_repExtRosInterface folder (or/and the other packages) into ~/catkin_ws/src **
catkin build

Cheers
