For example: BBCLASSEXTEND = "devupstream:target" SRC_URI_class-devupstream = "git://git.example.com/example" SRCREV_class-devupstream = "abcd1234" This variant will have DEFAULT_PREFERENCE set to -1 so it needs to be selected to be used, and any development-specific tweaks can be done with the class-devupstream override, for example: DEPENDS_append_class-devupstream = " gperf-native" do_configure_prepend_class-devupstream() { touch ${S}/README } It currently only supports creating a development variant of the target recipe, not native or nativesdk. The BBCLASSEXTEND syntax (devupstream:target) was chosen so that support for native and nativesdk can be added at a later date. Support for other version control systems such as subversion is limited, as bitbake's automatic fetch dependencies on for example subversion-native are not generated.
