INSTALL.OCTAVE tells me this:
`--without-blas'
Compile and use the generic BLAS and LAPACK versions included
with Octave. By default, configure first looks for BLAS and
LAPACK matrix libraries on your system, including optimized
BLAS implementations such as the free ATLAS 3.0, as well as
vendor-tuned libraries. (The use of an optimized BLAS will
generally result in several-times faster matrix operations.)
Only use this option if your system has BLAS/LAPACK libraries
that cause problems for some reason. You can also use
`--with-blas=lib' to specify a particular BLAS library
`-llib' that configure doesn't check for automatically.
but what is 'lib'? Should that be the directory containing the atlas
libraries? If so, I tried that and configure still finished with a blank
line after "BLAS libraries:". I guess I'm just not quite getting it and I
need a tip.
Thanks.
Mike
