Yocto and reTerminal

Products & Technology
#1

I am trying to compile on the command line an image for the reTerminal using Yocto. I followed the directions (to the best of my ability) on the Wiki Yocto - Seeed Wiki but the build fails.

Ubuntu 20.04 guest inside virtualbox, 6 core, 8192 MB RAM, 200 GB disk
The first error appears when I issue bitbake:

~/poky/build$ bitbake rpi-test-image
Loading cache: 100% |                                           | ETA:  --:--:--

ERROR: ParseError at /home/yocto/poky/meta-openembedded/meta-oe/recipes-extended/mraa/mraa_git.bb:21: Could not inherit file classes/setuptools3-base.bbclass

Summary: There was 1 ERROR message shown, returning a non-zero exit code.

Any pointers?

#2

There have been no replies. I had to switch over to VMware Player to achieve a stable ubuntu 20.04 client. I have built poky for qemux86 and the yocto image runs.

I am new to yocto - but I’ve seen this error before with outdated build systems. Can anyone give me pointers? I now have 10 reTerminals that I need to deploy.
