[ANN]New numpy, scipy and atlas rpms for FC 5, 6 and 7 and openSUSE (with 64 bits arch support)
Hi there, After quite some pain, I finally managed to build a LAPACK + ATLAS rpm useful for numpy and scipy. Read the following if you use Fedora Core or OpenSuse and are tired to install unsuccessfully numpy, scipy, BLAS, LAPACK or ATLAS. Instructions are given there: http://www.scipy.org/Installing_SciPy/Linux (ashigabou repository) Basically: - Fedora Core 5, 6 and 7 and openSUSE 10.2 are supported (x86, and x86_64 for FC 7 and openSuse). - binary rpms for numpy, scipy and blas/lapack dependencies. - source rpm for atlas, for a really easy, 3 commands build of ATLAS (should work for both x86 and x86_64). numpy and scipy are the last releases, including some backported changes to make it work on 64 bits. Atlas is the last developement version, with a trivial patch to build shared blas and lapack which can be used as drop in replacements for netlib blas and lapack. I would like to hear people complains. If people want other distributions supported by the opensuse build system (such as mandriva), I would like to hear it too. cheers, David

I tried your repository (http://software.opensuse.org/download/home:/ashigabou/openSUSE_10.2/) with two machines running openSUSE 10.2: 1. AMD Athlon desktop 2. Pentium-M laptop. The repository works with Yast (installation program). The prebuilt packages work on both machines. They especially work with matplotlib from the http://repos.opensuse.org/science/ repository. (I didn't try timers and testers.) Building Atlas succeeds on the Pentium-M (2). On the Athlon (1) the sanity checks fail. The resulting Atlas RPM is missing two links: /usr/lib/atlas/sse2/libblas.so.3 -> /usr/lib/atlas/sse2/libblas.so.3.0 /usr/lib/atlas/sse2/liblapack.so.3 -> /usr/lib/atlas/sse2/liblapack.so.3.0 When I try your one line examples, I see a nine times speedup with Atlas. Thank you for your efforts! You provide an easy way to install Atlas on Suse for the first time. Regards, Eike. PS.: I still think you should contribute to the http://repos.opensuse.org/science/ repository. Then this quite comprehensive repository would get decent Blas and Atlas too.

Ideally, you should not need LD_LIBRARY_PATH, and I should update the loader (the software which looks for shared libraries when launchdng a program) cache, but if I make a mistake at this point, this has the potential to screw up the whole machine....
Could you give me more information on the AMD failure ? Are you using 64 bits mode ?

This is planned, and I already took contact with them a few weeks ago, but I didn't have time to do it properly yet. David

No, its an old Athlon XP. I'll send you the log directory and the output of "make test" in private mail. It's 0.5 mb compressed. What else do you want? The Atlas RPM does also expose a weakness in Suse's installation program: It is not displayed in Yast. I think, because there is only a source RPM. Regards, Eike.
