Currently the code has problems differentiating between "gcc-cross" and "gcc-cross-initial" sstate files. We could add in a ton of special casing but tests show this isn't scaling well. Using a more unique separator resolves the issue. The choice of which separator to use is a hard one. We need something which isn't commonly used in PN, PV, PR, *_OS and *_ARCH which rules out '-', '_' and it needs to work ok with webservers/http which makes ';' and '%' harder. The change also sets SSTATE_SWSPEC globally since writing out differently named siginfo files for the fetch/unpack/patch tasks is a waste of diskspace, the hashes match for all PN in the majority of cases and if they don't, its not a big issue as the hash is different. This makes the results from sstate debugging more understandable. (From OE-Core rev: 6f823a23c5f1d0ffa0a27db1c1bc1907de788505) Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
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 = "") 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.
