The ipk or deb can't depend on file such as "/bin/bash" or
"/usr/bin/perl", so it knows nothing about the pkg depends bash or perl,
thus there would be dependencies problems when we run "apt-get
install/remove <pkg>" on the target, this check can help us find the
issues and then fix them manually.
* Benefits:
- Help to fix file rdepends issues for ipk and deb
- Help to fix abnormal rdepends.
- Help to check whether the rdepends is OK or not after build each
recipe (don't have to install to the image), for example, a recipe may
generate 10 binary packages, only a part of them will be installed to
the image by default, we can know whether the rdepends are OK or
not for the ones which are installed, but can't know the ones which
are not installed, this patch can help check all the 10 binary
packages' rdepends.
* Basic designs:
- Get all the RDEPENDS on the chain.
- Get the pkg's FILERPROVIDES from oe.packagedata.read_subpkgdata()
and save to set filerdepends.
- Get each RPDEPENDS' FILERPROVIDES, RPROVIDES and FILERPROVIDESFLIST,
and save to set rdep_rprovides.
- Do the set "filerdepends -= rdep_rprovides" and QA issue if
filerdepends is not null.

Poky
====
Poky is an integration of various components to form a complete prepackaged
build system and development environment. It features support for building
customised embedded device style images. There are reference demo images
featuring a X11/Matchbox/GTK themed UI called Sato. The system supports
cross-architecture application development using QEMU emulation and a
standalone toolchain and SDK with IDE integration.
Additional information on the specifics of hardware that Poky supports
is available in README.hardware. Further hardware support can easily be added
in the form of layers which extend the systems capabilities in a modular way.
As an integration layer Poky consists of several upstream projects such as
BitBake, OpenEmbedded-Core, Yocto documentation and various sources of information
e.g. for the hardware support. Poky is in turn a component of the Yocto Project.
The Yocto Project has extensive documentation about the system including a
reference manual which can be found at:
http://yoctoproject.org/documentation
OpenEmbedded-Core is a layer containing the core metadata for current versions
of OpenEmbedded. It is distro-less (can build a functional image with
DISTRO = "nodistro") and contains only emulated machine support.
For information about OpenEmbedded, see the OpenEmbedded website:
http://www.openembedded.org/
Where to Send Patches
=====================
As Poky is an integration repository, patches against the various components
should be sent to their respective upstreams.
bitbake:
bitbake-devel@lists.openembedded.org
meta-yocto:
poky@yoctoproject.org
Most everything else should be sent to the OpenEmbedded Core mailing list. If
in doubt, check the oe-core git repository for the content you intend to modify.
Before sending, be sure the patches apply cleanly to the current oe-core git
repository.
openembedded-core@lists.openembedded.org
Note: The scripts directory should be treated with extra care as it is a mix
of oe-core and poky-specific files.
