Error in rviz in first tutorial
I'm following the tutorial of rviz, Sending Basic Shapes in c++, and I have this error when I compiled the packages:
/home/edu/catkin_ws/src/using_markers/src/basic_shapes.cpp:32:10: fatal error: ros / ros.h: No existe el archivo o el directorio
32 | #include <ros / ros.h>

Please reformat your question, right now it's a mess and it's really hard to read. Did you source ROS and workspace after building (
source /opt/ros/noetic/setup.bash
+source ~/catkin_ws/devel/setup.bash
)?
