[MarinHure]

Hello,
I have done all the installations, and succeeded launching ORB-SLAM with the MH_01_easy.bag.
But when i try to launch
rosrun ORB_SLAM3 Mono Vocabulary/ORBvoc.txt Examples/Monocular/EuRoC.yaml
I get this error :
[rosrun] Couldn't find executable named Mono below /home/user/ORB_SLAM3/Examples_old/ROS/ORB_SLAM3

Can someone help me resolve this error ?

make changes to your build_ros.sh

cd Examples/ROS/ORB_SLAM3
mkdir build
cd build
cmake .. -DROS_BUILD_TYPE=Release
make -j

cp -v $PROJECTPATH/ORB_SLAM3/Examples/ROS/ORB_SLAM3/build/devel/lib/ORB_SLAM3/* $PROJECTPATH/ORB_SLAM3/Examples/ROS/ORB_SLAM
