I need to build ROS 2 Humble from source on a Beaglebone Black. When I do so, I get build errors. I followed the instructions on the ROS website.

As shown in the screenshot below, warning occur indicating some C++ expressions changed with gcc 7.1. Is there a specific compiler version required to build ROS 2 from source?

I also tried building with 'colcon build --symlink-intall --continue-on-error' and the build stops after 6 failures and 130 successful package builds. The output of this can also be found as the second screenshot provided.

If anyone has experience building ROS 2 Humble from source on armhf architecture or is aware of what is causing this issue, please let me know. If more information is required, please let me know as I am new to Linux and ROS.

Thank you Build output without continue on error

First: don't post text output as screenshots. Instead: copy-paste it in a code block, between ``` delimiters, e.g.:

```

[copy - paste]

```

Now, wrt the error: it is about RViz (rviz_ogre_vendor). I assume you don't need to run RViz on the Beaglebone. So I suggest to use colcon graph to check the dependencies of rviz_ogre_vendor, and just remove that package and all its dependencies from your source tree.

  • $\begingroup$ Thank you for the response, I will ensure the terminal output is added as text moving forward. As for removing packages from the build process, Ideally I would build the core packages and only build additional packages as required. Is there a way with colcon to build only the core packages? Or would I have to find the name of each core package and omit all others? $\endgroup$

  • $\begingroup$ I don't know unfortunately.. I found this thread in which the part on rosinstall_generator seems th most promising, but I have no experience with that. $\endgroup$
