Any chance that this can still go into the 2012.05 release? I have one customer who would be really pleased with that... Except for the dirs dependency, I think it can go in as it is. But of course I do have some optional remarks :-) > +TARGETS_LEGAL_INFO:=$(patsubst %,%-legal-info,\ > + $(filter-out host-makedevs,\ > + $(TARGETS) $(BASE_TARGETS) $(TARGETS_HOST_DEPS) $(HOST_DEPS)))) I guess host-makedevs is filtered out here because it has no tar file? In that case, the same should be done for makedevs and mcookie. But maybe it's better to define the SITE_METHOD of these packages as local. Then they will be registered as "not saved" in the manifest.

Or you could put it as ifneq ($$($(2)_MANIFEST_TARBALL),not saved) $(1)-legal-info: $(1)-extract $(REDIST_SOURCES_DIR) endif BTW, why is it $(3)_LICENSE here and $(2)_LICENSE below? > + > $(1)-show-depends: > @echo $$($(2)_DEPENDENCIES) > > @@ -412,6 +436,47 @@ else > $(2)_KCONFIG_VAR = BR2_PACKAGE_$(2) > endif > > +# Set values used later for legal-info manifest > +ifneq ($$($(2)_LICENSE),PROPRIETARY) > +ifneq ($$($(2)_SITE_METHOD),local) > +ifneq ($$($(2)_SITE_METHOD),override) > +$(2)_MANIFEST_TARBALL = $$($(2)_SOURCE) > +ifneq ($(call qstrip,$$($(2)_LICENSE_FILES)),) Why is there a qstrip here?

That saves a lot of double $$.
