Resolving the lapack, blas problem with ubuntu

[Nikolaos Vasiloglou II]

Many of you have noticed that when you choose the option 1 for installing lapack/blas fails because the make files use O3 optimization. Some of you fixed that by manually changing the flags from -O3 to -O2. I tried to use option 2 and use the installed blas/lapack libraries under /usr/lib. Unfortunatelly there is a known bug for ubuntu and when you are trying to staticaly link it fails because there is a dublicate symbol xerbla_ (for more information see:http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=354463)

It turns out that if you install on your UBUNTU system the atlas versions for blas/lapack (I believe this is the libatlas-base-dev package) then you can install fastlib by choosing option 2 (when the installer is asking you where to find lapack/blas) and use the installed libraries under /usr/lib/atlas/libblas.a and /usr/lib/atlas/liblapack.a
I tried that on the UBUNTU 8.10 and it worked
