If you never use sstate and always build everything from scratch you will never see this problem. However, if you use sstate and build directories that last a long time eventually you can end up with the scenario where libtool gets a hard coded path in it for sed, and sed may not exist. The reason you don't see this problem to often if you generally build from scratch is that libtool builds before sed and will pickup the host's /bin/sed. The way to reproduce the issue is: bitbake some_image bitbake -c cleansstate libtool-native bitbake sed-native bitbake libtool-native bitbake -c clean sed-native bitbake ANY_PACKAGE_THAT_USES_LIBTOOL_NATIVE In my case I used modphp, which doesn't exist in the oe-core. You will end up with a strange looking error like: | make[1]: *** [buckets/apr_buckets_alloc.lo] Error 1 | /opt/build/bitbake_build/tmp/sysroots/x86_64-linux/usr/bin/x86_64-linux-libtool: line 981: /opt/build/bitbake_build/tmp/sysroots/x86_64-linux//bin/sed: No such file or directory The solution is to always use /bin/sed for libtool-native.

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.
