[PATCH 0/1] bitbake wrapper: exit if python v3 is detected

[PATCH 0/1] bitbake wrapper: exit if python v3 is detected

[Scott Garman]

Make sure we're not using python v3.x. This check can't go into
sanity.bbclass because bitbake's source code doesn't even pass
parsing stage when used with python v3, so we catch it here so we
can offer a meaningful error message.

This fixes bug [YOCTO #1128]

I did attempt to make changes to bitbake to get the source code to
parse under python v3, but there are issues which make it too
difficult to get the code to work with python v2 and v3. For example,
importing modules within a package has changed significantly in v3
in such a way that breaks compatability with v2.

The following changes since commit 7aa7673459376aff911cef820c9417c998d1aa96:

  meta-yocto/linux-yocto: update to match the renamed linux-yocto recipes (2011-06-14 09:21:32 -0700)

Try posting it on the OE-core list?

Merged to master but please send OE-Core related patches to the OE-Core
list in future.
