There will be errors when the length of the tmpdir is longer than 410:
1) Longer than 420:
Can't exec "/bin/sh": Argument list too long at /usr/lib/perl/5.10/IO/File.pm line 66.
This error happens on both Ubuntu 10.04 and 10.10 when the pkg needs run
"autoreconf", this is because it passes many files with absolute path to
aclocal, aclocal passes them to perl, this is a limitation of the perl
on Ubuntu 10.04 and 10.10, and the perl-native is not ready at this very
early stage.
2) Longer than 490:
bitbake/lib/bb/persist_data.py", line 197, in connect(database=...)
> return sqlite3.connect(database, timeout=5, isolation_level=None)
OperationalError: unable to open database file
This error happens on Ubuntu 10.04, 10.10 and Fedora 17. This is because
the length of the database in sqlite3 module (host's) can't be longer
than 490 (or little smaller). The python-native is not ready at this
very early stage.
The 2 errors are host related, I think that limit the length of the
TMPDIR to 410 is OK for most of the build, rarely build sets TMPDIR's
longer than 410.

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:
