During normal bitbake execution, the environment is cleaned of variables not on a whitelist while starting up cooker, and then restored afterwards. Prior to the tinfoil2 rework in master we were taking a number of shortcuts within tinfoil and one of those was not doing this environment cleaning. However, prior to OE-Core rev 3d39ca5c91dbb62fb43199f916bd390cd6212e3d we didn't have any code (as far as I'm aware) that was affected by this shortcut, hence why this wasn't an issue up to now. The result is the following error when attempting to run "devtool build" in the eSDK, as CCACHE_PATH is allowed through from the eSDK's environment setup script: ----------- snip ----------- ccache: error: Could not find compiler "gcc" in PATH ... subprocess.CalledProcessError: Command 'gcc --version' returned non-zero exit status 1 ----------- snip ----------- We can fix this by simply doing the environment filtering while we are starting up cooker, thus the environment when uninative.bbclass comes to do the gcc version check it is not affected by CCACHE_PATH or other variables in the external environment that should be filtered out. For clarity, this patch is only applicable to the bitbake 1.32 branch as used for the OE-Core morty branch - master uses the reworked tinfoil2 and doesn't need this fix. Fixes [YOCTO #10961].

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 (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
bitbake: Git repository: http://git.openembedded.org/bitbake/ Mailing list: bitbake-devel@lists.openembedded.org
documentation: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/ Mailing list: yocto@yoctoproject.org
meta-poky, meta-yocto-bsp: Git repository: http://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto(-bsp) Mailing list: poky@yoctoproject.org
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.
Git repository: http://git.openembedded.org/openembedded-core/
Mailing list: 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.
