Well, I guess we are :-) Let us know what you had to do to get it to work.
This is so Absoft-specific that I'm not sure how much it helps others, but here goes: I built LAPACK after modifing the make.inc.LINUX file to set the compiler and linker to /opt/absoft/bin/f77 instead of to g77, and the compile flags to "-O3 -YNO_CDEC". I ran "make config" in the ATLAS directory and told the setup that /opt/absoft/bin/f77 was my Fortran compiler, then did "make install arch=", then followed the scipy.org instructions to combine LAPACK with the one from ATLAS. Finally, I applied the attached patch to addons.py in the numarray directory. Interestingly, the example program runs in 1.43 seconds on a 2.26GHz P4 with the default numarray install (as opposed to 4.95 seconds on the Athlon). I haven't built ATLAS on this platform yet to find how much of an improvement I get. I suppose something similar would work with g77, replacing the Absoft libraries with g2c, but I haven't tried it. -- Stephen Walton <stephen.walton@csun.edu> Dept. of Physics & Astronomy, Cal State Northridge
