Launch error

[SyahirMuzni]

Hi,
I have successfully built the package and did the intrinsic calibration. I did change some of the requirements in the launch file to match up with my sensors.
But I have an error when I tried to launch the package. I did catkin_make clean & change the permissions as well. But there's no difference.

ERROR: cannot launch node of type [linkalibr/ros_calib_init]: Cannot locate node of type [ros_calib_init] in package [linkalibr]. Make sure file exists in package path and permission is set to executable (chmod +x)
ERROR: cannot launch node of type [linkalibr/ros_calib_init_optimizer]: Cannot locate node of type [ros_calib_init_optimizer] in package [linkalibr]. Make sure file exists in package path and permission is set to executable (chmod +x)

For your information,
My system is running ubuntu 20.04 (noetic)

[SubMishMar]

Have you sourced the workspace?

To source: Run
source devel/setup.bash
at the top level of your workspace. http://wiki.ros.org/catkin/Tutorials/create_a_workspace

I have never tried running this on ros noetic.

[SyahirMuzni]

Yes I have sourced it.

[SubMishMar]

Okay. Then I have no idea. I would suggest you to use the docker version. You can find it in the README.

use @alwynmathew cmakelists.txt and if you have error about fstream just change in ros_calib_init_optimizer.cpp the fstream line with this

#include <fstream>
