Cmake Warning

[carleft]

Hello!

I have a warning when I run cmake ..

` Cannot generate a safe runtime search path for target mola-input-ros1 because files in some directories may conflict with libraries in implicit directories:

runtime library [libcv_bridge.so] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /opt/ros/kinetic/lib
runtime library [libtf2.so] in /usr/lib/x86_64-linux-gnu may be hidden by files in:
  /opt/ros/kinetic/lib

` How can I solve it? Thanks in advance!

It seems you have the ROS Kinetic setup script being called automatically in your ~./bashrc, then you also have some ROS packages from the official Ubuntu repo (probably because you followed the MOLA build instructions?).

I see two ways to solve this:

A) If you plan to keep using ROS Kinetic often from the same console / apps than MOLA, uninstall ROS packages from the official Ubuntu repos: sudo apt uninstall libroscpp-dev libsensor-msgs-dev libcv-bridge-dev, and any other package for which you have a warning.

B) You can remove the automatic inclusion of ROS Kinetic from bashrc (the source /opt/ros/... line), and then MOLA will build against the Ubuntu official packages. From a different terminal, you can always source the ROS Kinetic file and keep using ROS.

Personally I use (B) since that allows me to use different versions of ROS (ROS 1, ROS 2,...), and define a bash alias to quickly source the corresponding setup.bash file, but it's up to each one which way to go...

So it means that I should delete the code source /opt/ros/kinetic/setup.bash from ~/.bashrc ?

And if I want to use ros in /opt/ros, do I need to run source /opt/ros/kinetic/setup.bash in the terminal?

Yes, exactly, that's the option B above...

Thanks a lot ! It's very useful for me !
