Re: Error while building Xen

[Deepthi M. <Deepthi.M@xxxxxxxx>]

Hi Bertrand,

I switched all the meta layers to Rocko but meta-demo/meta-rcar-gen3-xen is master branch. I got the following error.

user@user-OptiPlex-7010:~/build/build$ bitbake core-image-weston

Parsing recipes: 100% |#########################################################################################################| Time: 0:01:45

Parsing of 2104 .bb files complete (0 cached, 2104 parsed). 2925 targets, 91 skipped, 3 masked, 0 errors.

ERROR: No recipes available for:

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

Thank you,

Deepthi

This is a very old release (4 to 5 years old) and it is not supported anymore.

Since this was written it could really be that Renesas updated their support so you might try to check an newer version of the gen3 support:

and use the corresponding version of meta-virtualization.

There are some patches for pygrub on meta-virtualization master that you might want to look at:
