installation problems with SciPy
Hi, just changing LD_LIBRARY_PATH did not make a difference. I tried reinstalling scipy with the LD_LIBRARY_PATH set, and somehow this installation crashed with the following final lines: building extension "scipy.io.numpyio" sources building extension "scipy.linalg.fblas" sources generating fblas interface 20 error: build/src/atlas321/fblas.pyf: No such file or directory Now I am confused again... How did I break this?

Did you remove build directory before reinstalling scipy? If not then do that and rerun scipy build/install commands. Sometimes building ATLAS yourself or using prebuilt ATLAS libraries from http://www.scipy.org/download/atlasbinaries/ is easier than trying to use system provided ATLAS, especially when the system is oldish and you don't have enough permissions to fix the system.

I did. Apparently the problem was indeed that the atlas installation on our systems is outdated. (Like almost all other software that is managed by the system group ;-) ) Installing the atlas binary in some directory dir/ and pointing both LD_LIBRARY_PATH and ATLAS environment variables to dir/ worked. Now everything runs smoothly! (I tried installing the binary myself before but this didn't work. This will probably also have been due to not setting LD_LIBRARY_PATH.) Now the output of python -c 'import atlas_version' is ATLAS version 3.6.0 built by pearu on Sun Apr 11 01:13:26 EEST 2004: UNAME : Linux p4.home.net 2.6.0-p4.10 #1 SMP Fri Jan 2 13:37:10 EET 2004 i686 GNU/Linux INSTFLG : MMDEF : /home/pearu/src/ATLAS/CONFIG/ARCHS/P4SSE2/gcc/gemm ARCHDEF : /home/pearu/src/ATLAS/CONFIG/ARCHS/P4SSE2/gcc/misc F2CDEFS : -DAdd_ -DStringSunStyle CACHEEDGE: 1048576 F77 : /home/pearu/bin/g77, version GNU Fortran (GCC) 3.3.3 (Debian 20040314) F77FLAGS : -fomit-frame-pointer -O -fno-second-underscore CC : /home/pearu/bin/gcc, version gcc-3.3 (GCC) 3.3.3 (Debian 20040314) CC FLAGS : -fomit-frame-pointer -O3 -funroll-all-loops MCC : /home/pearu/bin/gcc, version gcc-3.3 (GCC) 3.3.3 (Debian 20040314) MCCFLAGS : -fomit-frame-pointer -O which looks like it is what it was supposed to be... Thanks for the patient help! I would never have done this on my own! Bye, Giovanni
