When using '--why' option, we currently only list elements. It's better to print out dependency chains. This patch adds such abitility. e.g. $ oe-depends-dot -k util-linux -w recipe-depends.dot Because: packagegroup-core-boot systemd-compat-units systemd shadow core-image-minimal dbus e2fsprogs core-image-minimal -> packagegroup-core-boot -> systemd-compat-units -> systemd -> dbus -> shadow -> util-linux core-image-minimal -> packagegroup-core-boot -> systemd-compat-units -> systemd -> dbus -> e2fsprogs -> util-linux (From OE-Core rev: 1115e06599751f776134674d93627cc381a06660) Signed-off-by: Chen Qi <Qi.Chen@windriver.com> Signed-off-by: Ross Burton <ross.burton@intel.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
QEMU Emulation Targets ====================== To simplify development, the build system supports building images to work with the QEMU emulator in system emulation mode. Several architectures are currently supported in 32 and 64 bit variants: * ARM (qemuarm + qemuarm64) * x86 (qemux86 + qemux86-64) * PowerPC (qemuppc only) * MIPS (qemumips + qemumips64) Use of the QEMU images is covered in the Yocto Project Reference Manual. The appropriate MACHINE variable value corresponding to the target is given in brackets.
