The autogen-native built error on FC17: ccache: failed to create /dev/null/.ccache This is because the default gcc command of FC17 is a symlink to ccache, so the ccache will always be used regardless to the setting of CCACHE, ccache uses $HOME/.ccache as the CACHE_DIR by default, but autogen set HOME=/dev/null, so the error happens. Disable ccache explicitly if it is not enabled would fix the problem, otherwise it would always use ccache regardless to the setting of CCACHE on Fedora 17. The ccache 3.1.7 has a bug, it would always create $CCCHE_DIR/.ccache even CCACHE_DISABLE=1. Unset CCACHE_DISABLE in ccache.bbclass, since ccache only checks whether there is a CCACHE_DISABLE in the environment or not, it doesn't care about its value, so we need unset it explicitly when enable ccache.

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.
