Hello!

I have a question totally related to inexperience with gfortran. I am trying to install ATLAS with a full LAPACK on an 8 core OpenSUSE server. I am following the instructions in http://math-atlas.sourceforge.net/atlas_install/node47.html and when I make a bogus directory and configure ATLAS with '../configure -b 64 -t 8 --prefix=/usr/lib64/atlas --shared --with-netlib-lapack-tarfile=/opt/maths/lapack-3.4.2.tgz -Fa alg -fPIC' my fgrep for F77FLAGS gives 'F77FLAGS = -O -mavx -fPIC -m64 -fPIC'. I get an error when I try to compile LAPACK with the -maxv option, I am also unable to find any information about the "-maxv" switch anywhere on the internet. What is it? If I exclude it will ATLAS and LAPACK work together?

Also if I add -O3 to my ATLAS configure step when I fgrep I get both -O and -O3 switches is this normal?

TIA

Matt

    Oops. Ok I guess it was a typo. I used -maxv instead of -mavx. Its compiling now. thanks!
