Re: crosstool-NG build fails

["piper.guy1" <piper dot guy1 at gmail dot com>]

Yes thank-you. It makes sense now that I look back. I'm trying to get
up to speed on Linux and embedded Linux. I hope I'm allowed to use my
one dumb question credit for this one. :-)

But, now that I can continue, I have come up against another problem.
There's some component that it can't download:

        [INFO ]  Retrieving needed toolchain components' tarballs
        [EXTRA]    Retrieving 'cloog-ppl-0.15.7'
        [ERROR]    Could not retrieve 'cloog-ppl-0.15.7'.
        [05:46] / make: *** [build] Error 1

I've tried several times.

Any thoughts on this?

thanx
/carl h.
