When building, bitbake often fails to parse in my configuration.  The exact message is:

ERROR: Error Method already seen: get_policyconfigarch in' libselinux_2.1.9.bb' now in 'libselinux_git.bb'

In order to reproduce this problem:

Host system - Fedora 16 - i686 (32-bit) - Core 2 Duo system

Python version 2.7.2

OE-core master -- commit: e3113827810e98eb1b012f0b280fb917199704c1
Bitbake master -- commit: 56c1ab18fcaf4ac245dcb412ed55e8e0af07883b
meta-selinux master -- commit: a424d778f3b92a315553383ac1a6bcca682f6007

Use . ./oe-init-build-env to setup a default configuration, modify it:

BB_NUMBER_THREADS = "2"

PARALLEL_MAKE = "-j 2"

Add the meta-selinux to the bblayers.conf file:


# LAYER_CONF_VERSION is increased each time build/conf/bblayers.conf
# changes incompatibly
LCONF_VERSION = "4"

BBFILES ?= ""
BBLAYERS ?= " \
  /home/buildbot/temp-fray/openembedded-core/meta \
  /home/buildbot/temp-fray/openembedded-core/meta-selinux \
  "


I then ran bitbake in a loop:

while bitbake -e libselinux ; do rm -rf tmp-eglibc ; done

Within 2-3 runs, I usually receive the failure message indicated above.  (This issue was also reproduced with the version of bitbake and oe-core in the Yocto Project 1.2 release.)

Note: I was -not- able to reproduce this problem w/ Python 2.6.x that comes with CentOS 6.2, or a Fedora 13 machine running a similar python version.
