unable to build the bookros2_ws workspace

[versavel]

When attempting to build the workspace as described in chapter 1.1.3, I get the following output with errors. I tried to downgrade the setuptools (pip install setuptools==58.2.0) as that resolved issues I had building the ROS2 tutorial examples in a ROS2 Humble "base" docker container on a RPi v4B. But that doesn't work here with ROS2 Humble "Desktop" installed on AMD64 Ubuntu Jammy machine.

Anything else I could try to successfully build the workspace ?

Thanks

Hi @versavel

I think this is related to something in your installation, but it is strange. I will check it. Did you execute rosdep in the workspace? (rosdep install --from-paths src --ignore-src -r -y in your workspace root)

[versavel]

yes, I did.

When I posted the output above, I had already deactivated conda, but not deleted the build, install, and log directories. When doing a clean build, I got different errors. I have also tried to use the humble-devel branch code. No luck with that either.

I currently have the errors below. Anything else I could try, or may have overlooked ?

Thanks.

Summary: 35 packages finished [26.0s]
  3 packages had stderr output: br2_fsm_bumpgo_py groot launch_pal

[fmrico]

I don't see errors, only warnings in Groot. I think you can continue with this. Yeah, Conda is a problem sometimes.

[versavel]

The "3 packages had stderr output" message confused me.

I installed and used an official OSRF ROS2 humble fulldesktop docker image to build the workspace and got the same summary output. So my installation should be fine.

I will close the issue and contine to the next chapter in the book :)

Thank you, Francisco !

Solution : Deactivate Conda AND do a clean build.

[fmrico]

Yes!! Conda is always a problem for ROS :disappointed:
