georgfaust commented 3 years ago

the wiki assumes some knowledge of yocto that I do not have, but I like to give WPE a try.

here is what I did:

  1. follow the yocto quick-build https://docs.yoctoproject.org/brief-yoctoprojectqs/index.html (but did not checkout a release branch, because if I understand correctly WPE wants to work with master as of readme.md)
  2. in poky clone the repos mentioned in the readme
  3. source oe-init-build-env
  4. edit build/conf/bblayers.conf and build/conf/local.conf according to wiki
  5. poky$ bitbake core-image-weston

here is the error I get:

poky$ bitbake core-image-weston

I'm a bit surprised about that error because openjpeg is part of the /meta-openembedded/meta-oe/ layer (in recipes-graphics/openjpeg) and I suppose that layer is one of the one suggested in the minimal scenario of the quick start guide in Yocto.

However, I sympathize with the idea of to provide a quick start guide. We thought that was addressed by the following documents:

Was you aware of them? If not, could you give them a try? if they are not clear enough. Do you have any suggestion to improve them? Ideas are welcome.

georgfaust commented 2 years ago

I will, as soon I've got the time and be back.

psaavedra commented 2 years ago

Those documents pointed by the previous comment were recently refreshed with clean-ups and updated information.
