ROS Noetic Windows Package not found after catkin_make

edit

@cjonesy, one possible problem is that you didn't invoke devel\setup.bat to merge your catkin workspace, so it wasn't visible to any ROS tools. I saw you asked the similar question here. It would be great to confirm your usage.

Isn't this your own #q361870, but then in Windows?

Here's a little more background. This is a small RC car with a Raspberry PI 4 on it along with an IMU, Ultrasonic Sensor, and RGB camera. Looking into using ROS for future semesters of a Masters CS class in IoT.

Ultimately I'm trying to run rviz and ros QT on Windows for visualization of sensor data and camera feed.

I just ran devel/setup.bat and tried roscd picar again, same result. Package couldn't be found. I tried running catkin_make after I ran setup.bat, same result. I went back to #q361870 and marked it as answered.

@cjonesy, are you able to detail how to replicate the catkin workspace (or share the sources)? Also, it might be useful to share your catkin_make (or catkin_make_isolated) console logs.

@Sean Yen: shouldn't @cjonesy run call devel\setup.bat instead of directly running it?

Call devel\setup.bat (or devel_isolated\setup.bat) first and then invoking the ROS tools should just work. The workflow should be the same regardless of the platform. And if @cjonesy does the same steps on Windows as those on Linux, but it still doesn't work. Then, I am curious of @cjonesy workspace and even the build logs. There might be something else to do with that.

My command line shortcut was pointing to setup.bat under /opt. So I changed that. But the target field was too long for windows so I moved the ros_catkin_ws to a shorter folder name. Interestingly I'm able to do rosrun picar script.py and it runs and the node will show up on the RPi when doing rosnode list.

However when I run another script, rosrun picar IMUPub.py (publishes IMU data) and run rostopic echo /orientation on the RPi it's fine. But when I try to run rostopic echo /orientation in Windows I get this error showing up on the RPi and no data in Windows.

And while rosrun works in Windows, roscd gives me this error:

C:\Users\cjones\Documents\ros_catkin_ws\src\picar\src>roscd picar

How do I post build logs? Just the output from catkin_make?
