Re: Compiling Octave with ATLAS

[David Parks]

Oops, sending to the list this time, silly reply button...

Yes, yes, and YES! You nailed it, sadly I figured it out right about the 
same time as I read this.   But this absolutely, without a doubt, should 
go in the FAQs, and also the install docs, and a note in the configure 
file --help text with a nice concrete example.

I've found numerous related questions scattered across the web, all 
without answers. I did a little writeup on Stack Overflow and posted 
links to it in various places.

However that still left me with a remaining install issue, I'm going to 
put it in another thread though.

Thanks for the reply!
