My expectations is that any existing dependency set will be managed and maintained by the existing primary toolchain, unless a given recipe has a specific dependency on a secondary toolchain item. I.e. the example above will -always- be the primary toolchain from a dependency resolution standpoint.. If the recipe adds "virtual/icc", then something, such as icc, needs to exist to provide that. Does this seem like a reasonable behavior and expectation? (The thing to remember is this secondary toolchain is just that.. an alternative to the primary for specific users and NOT general purpose....) --Mark > _______________________________________________ > Openembedded-core mailing list > Openembedded-core@lists.openembedded.org > http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/openembedded-core >
