bitbake: bitbake-layers: print the recipe's depends that crosses a layer boundary
Figure out the dependency between recipes that crosses a layer boundary * Introduction: - For the .bb file, we need check the following depends: > Check the DEPENDS, RDEPENDS and inherits according to the cooker_data. > The cooker_data doesn't have the info about "require/include xxx", so we need check them manually. - For the .bbclass, .inc and .conf file, we can't get their file depends from the cooker_data, we need check them manually. * Usage: $ bitbake-layer show-cross-depends I don't like the name "show-cross-depends", figure-out-cross-depends might be better, but most of the commands are "show-xxx" for bitbake-layers. * Output: (snipped) /work/poky/meta/recipes-support/libusb/libusb-compat_0.1.4.bb inherits /work/poky/meta-yocto/classes/poky-sanity.bbclass /work/poky/meta-intel/meta-cedartrail/recipes-cdv-media/images/core-image-cdv-media.bb requires /work/poky/meta/recipes-sato/images/core-image-sato.bb /work/poky/meta-yocto/recipes-core/tiny-init/tiny-init.bb RDEPENDS /work/poky/meta/recipes-core/busybox/busybox_1.20.2.bb /work/poky/meta-intel/common/recipes-bsp/amt/lms_7.1.20.bb DEPENDS /work/poky/meta/recipes-devtools/autoconf/autoconf_2.69.bb /work/poky/meta/classes/distrodata.bbclass includes /work/poky/meta-yocto/conf/distro/include/package_regex.inc /work/poky/meta-intel/meta-sys940x/conf/machine/sys940x.conf requires /work/poky/meta/conf/machine/include/tune-atom.inc [YOCTO #3387] (Bitbake rev: 100502ef722bf19b6c125a5e017f31686ad18421) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
