Hi all,
Where can I find some hints w.r.t. to ATLAS and scipy/numpy ? AFAIK the new website has no information on building ATLAS.
Do I need version 3 of gcc ?
I am on SuSE Linux 10.0 with gcc v4.0.2
If I try to install ATLAS I get ..
Looking for compilers (this may take a while): /usr/bin/gcc : v4.0.2 /usr/bin/gcc : v4.0.2 F77 = /usr/bin/g77 -fomit-frame-pointer -O -m64 CC = /usr/bin/gcc -fomit-frame-pointer -O -mfpmath=387 -m64 MCC = /usr/bin/gcc -fomit-frame-pointer -O -mfpmath=387 -m64 On a different distribution (ubuntu), I install ATLAS package, and modifiy the static library to build a full LAPACK library (it should be somewhere on the wiki, I can give more details if you need help).
From my POV, the best solution is to use a pre-compiled ATLAS from your distribution: then, it should have been tested, and you are less likely to make a error which can appear later in a very subtle way. Compiling and installing gcc yourself is a PITA if you have never done it yourself before (it is easy to break many things). Even building atlas yourself is a bit long, and I think it is easy to mess things up, at least from a
If SUSE does not have atlas package, then try to find if a gcc-2.95 package is available. If neither of them are available, I would advise you to just build ATLAS with your current version of gcc. performance point of view. David
