Error with enable-64

[Mark Rogers]

I'm trying to install Octave on an x86_64 Linux machine with 64GB memory. 
I spent most of a day following the steps on the website
(http://www.gnu.org/software/octave/doc/interpreter/Compiling-Octave-with-64_002dbit-Indexing.html)
as closely as I could, but I'm still getting the following error:

"configure: error: BLAS doesn't seem to support 64-bit integers. This is
incompatible with --enable-64."

My configure command:

./configure LD_LIBRARY_PATH=/usr/lib CPPFLAGS="-I/usr/include"
LDFLAGS="-L/usr/lib" --enable-64

The only part of the installation that didn't match the website was for
the SuiteSparse package, as it no longer has anything called
"UFconfig/UFconfig.mk", so I edited the file
SuiteSparse_config/SuiteSparse_config.mk to make the same changes.

At the moment I'm simply uninstalling all the changes I made and
reinstalling the tiny version of Octave I can get through the Synaptek
package manager, but I'd really like to get a larger version working.

thanks,
Mark
