We have an open bug about the warnings issues in builds from an sstate cache when something like glib-2.0 gets rebuilt. The issue is that sstate is "clever" and prunes unneeded dependencies out the tree. For example is X depends on pkgconfig-native but we've already build X and installed it from sstate, it will not get installed when you build Y which depends on X. This patch changes the logic to match the sstate behaviour and prune out unnecessary dependencies from the scope of aclocal. This in turn removes the warning about missing manifest files. The issue is that this patch exposes holes in our DEPENDS in recipes, specifically that some native tools are not listed, specifically, and problematically, pkgconfig, gtk-doc and intltool-native in particular. I've sent out patches against OE-Core that address the bulk of the issues there however I'm conscious this is probably going to a bug issue in other layers and may be too annoying to consider at this point. The other alternative is simply to turn the warning into a debug statement. I appreciate the code below has commented blocks, this is simply debug I've left around for now. It will be cleaned from any final version. (From OE-Core rev: 6d2dc279faa8b28a00895dc6a620d80e2dbac685) 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 = "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.
