Couldn't find executable named Mono below

[wdjiang]

I run SLAM3 using the following command:
rosrun ORB_SLAM3 Mono Vocabulary/ORBvoc.txt /home/ORB_SLAM3/Examples/ROS/ORB_SLAM3/Asus.yaml
error：
[rosrun] Couldn't find executable named Mono below /home/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3
There is no executable program Mono in my code. Whether using build_ros.sh or build.sh, it compiles successfully.
Executing roslaunch usb_cam usb_cam-test.launch functions are also normal;

Using cmake to compile Mono in the /home/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3# directory will produce an error
/home/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3/src/ros_mono_inertial.cc:28:9: fatal error: ros/ros.h: No such file or directory

compilation terminated.
And the following files cannot be found：
#include<ros/ros.h>
#include <cv_bridge/cv_bridge.h>
#include<opencv2/core/core.hpp>
#include"../../../include/System.h"

I need your help！！！！

[soumya997]

dude, could you find a solution to this?

[soumya997]

Okay, I found the solution.

You need to change the cd [path] in build_ros.sh file.

that file has cd Example/ROS/, which doesn't exists, change it to cd Example_old/ROS/
