Hi all,

It would be very helpful, if some information would be available at a c
e n t r a l place
e.g. http://www.scipy.org/documentation/buildatlas4scipy.txt
(instead of scanning mailing lists ;-) )
on how to install newcore/newscipy on 64 bit systems.

I have used

g77  -funroll-all-loops -O3 -m64 -fno-second-underscore -fPIC -c *.f
ar r libfblas.a *.o
ranlib libfblas.a

to build the BLAS library.

The modified entries in make.inc for LAPACK are

OPTS     = -funroll-all-loops -O3 -m64 -fno-second-underscore -fPIC
NOOPT    = -m64 -fno-second-underscore -fPIC

Some information on ATLAS should be added as well. So far I have only
used BLAS/LAPACK.

Nils
