[OE-core] [PATCH V2 1/6] libssp-nonshared: Add recipe

Mon Apr 30 15:21:16 UTC 2018

Now I've actually read what you wrote, I see I didn't miss it ;)

Now it fails like this:

ERROR: Nothing RPROVIDES 'rpcsvc-proto' (but
/home/pokybuild/yocto-autobuilder/yocto-worker/build-appliance/build/meta/recipes-core/packagegroups/packagegroup-self-hosted.bb
RDEPENDS on or otherwise requires it)

Also:

NOTE: Multiple providers are available for virtual/crypt (glibc, musl)
Consider defining a PREFERRED_PROVIDER entry to match virtual/crypt
