This change seems to cause problems for musl libc builds (I'm using today's oe-core master and Khem's meta-musl layer). ERROR: Nothing RPROVIDES 'nativesdk-glibc' (but /home/andre/rdk/rdk-master-musl/openembedded-core/meta/recipes-core/meta/uninative-tarball.bb RDEPENDS on or otherwise requires it) ERROR: nativesdk-glibc was skipped: PREFERRED_PROVIDER_virtual/nativesdk-x86_64-rdksdk-linux-libc-for-gcc set to nativesdk-musl, not nativesdk-glibc ERROR: Required build target 'rdk-image-wpe' has no buildable providers. Missing or unbuildable dependency chain was: ['rdk-image-wpe', 'uninative-tarball', 'nativesdk-glibc'] Reverting this one commit (oe-core 9a3b992) gets the builds working again. > [YOCTO #4102] > > Signed-off-by: Richard Purdie <[email protected]> > > diff --git a/meta/classes/base.bbclass b/meta/classes/base.bbclass > index 44ca781..b8f2aea 100644 > --- a/meta/classes/base.bbclass > +++ b/meta/classes/base.bbclass > @@ -204,7 +204,7 @@ def buildcfg_neededvars(d): > bb.fatal('The following variable(s) were not set: %s\nPlease set > them directly, or choose a MACHINE or DISTRO that sets them.' % ', > '.join(pesteruser)) > > addhandler base_eventhandler > -base_eventhandler[eventmask] = "bb.event.ConfigParsed bb.event.BuildStarted > bb.event.RecipePreFinalise bb.runqueue.sceneQueueComplete" > +base_eventhandler[eventmask] = "bb.event.ConfigParsed bb.event.BuildStarted > bb.event.RecipePreFinalise bb.runqueue.sceneQueueComplete > bb.event.RecipeParsed" > python base_eventhandler() { > import bb.runqueue > > @@ -257,6 +257,25 @@ python base_eventhandler() { > bb.debug(1, "Executing SceneQueue Completion commands: %s" % > "\n".join(cmds)) > bb.build.exec_func("completion_function", e.data) > os.remove(completions) > + > + if isinstance(e, bb.event.RecipeParsed): > + # > + # If we have multiple providers of virtual/X and a > PREFERRED_PROVIDER_virtual/X is set > + # skip parsing for all the other providers which will mean they get > uninstalled from the > + # sysroot since they're now "unreachable".
