Just before I joined. Sorry my search of the archives missed the above.

Yes, getting the info into a wiki page started the thread, but afraid I
don't quite understand how the process can be automated.  Back to the
January post...

Perhaps on the Wiki at
or perhaps soon on the "real" one?

Ditto for me - on FC6.

(Got'ta be emacs!!! :-)

OK - this is different from the original Recipe from Michael - results
in quite a lot more in build/conf/local.conf.

Here's where I got confused with your directions and had to do several
iterations on the environment variables in local.conf and the directory
structure.  This and/or the next definition are not consistent with
$OE_DIR above. I used

DL_DIR = "${HOME}/openembedded/sources"

and here used

BBFILES = "${HOME}/openembedded/*/*.bb"

First had to do

export BBPATH=${HOME}/openembedded/build:${HOME}/openembedded/


I put that in ~/.bash_profile

Built toolset and nano in 1 hour 21 minutes on an Intel Duo T2400  @
1.83GHz laptop with 1.5GB versus 3 hours 39 minutes on a VMware
Workstation Ubuntu VM on the same hardware.  Quite a bit of overhead for
this VM approach.

Thanks for the help, all.  Next steps, trivial app and emulation.

[Michael - created an account on the Wiki and will have a go at creating
a Red Hat distros page for FC6, and assuming these changes work there
too - CentOS/EL4.]
