how to convert source rpm spec to bitbake recipe?

[Michael Fainstein]

Is there a tool or guide for conversion of source rpm spec file to bitbake recipe?

I have a distro for our embedded product based on CentOS 5 with about 140 packages. Third are source rpm packages from CentOS without any change, third are with some of our proprietary changes and the rest are our proprietary packages in source rpm format. All source code is in our local repository (Perforce). I use RPM on native host server to build binary rpm packages and use binary rpms for software upgrade on our product. Both build on host and  install on target are driven using the same rpm spec file. Our product uses Freescale's PowerPC CPUs, so I am using PowerPC server to build our distro natively. I'd like to switch to cross-build using bitbake.
So I need to write 140 bitbake recipes that build my packages the same way as RPM and create binary rpm packages with my current existing specs for compatibility with our existing units in the field. That brings me to my question: is there a tool or guide for conversion of source rpm spec file to bitbake recipe that preserve all rpm spec scriplets?

Thanks,
Michael

There is scripts/create-recipe - this is aimed at just downloading source and 
using a spec file contained within as a basis for a new recipe (among other 
methods it uses to determine recipe contents), however it could be adapted to 
read a specified spec file I would think.

Cheers,
Paul

Hi Paul,
good to know.

Does this script also helps with packaging?

For KDE there are tons of sub-packages within one recipe, adding them
per hand is the major time factor in this case.
Currently I use a decrepit script [1] to do this, but maybe I can use
this one if it meets my expectations.

Hi Samuel,
kde-spec2bb.sh script references spec2bb.inc script. Can you post a link to it?

Thanks,
Michael

The spec2bb.inc only handles the parameters.
But sure here is the link: http://pastebin.com/S64CkYUa
