Hi, to summarize: just go on with gcc4. It works (although things may not be optimal, but I would guess the difference may be only 10% or so). ==> below is the way I compile things on Suse 10 with gcc4 starting with Lapack and going up to matplotlib. I have no problem with it although compiling ATLAS is a real pain (it just takes forever). Hope this helps. Please adapt things to your machine and system (using the right architecture name for ATLAS). Things that I don't do anymore are commands starting with "#". ALso please update some of the version numbers (ipython, matplotlib). A cleaned and updated version of such a simple procedure would be very helpful, if someone can post it. cheers Eric ============================= ####################### # LAPACK # ##################### # Build Lapack from the web since then you are sure it is complete # It is in the Suse distribution but I don't trust it wget http://www.netlib.org/lapack/lapack.tgz mdkir install_lapack cd install_lapack tar xvfz ../lapack.tgz cp INSTALL/make.inc.LINUX make.inc ## This will build a lapack_LINUX.a ## That you will use later on for ATLAS make lapacklib ######################## # ATLAS # ###################### tar xvfz atlas3.6.0.tar.gz cd ATLAS ## You will have to answer a few questions... # don't care about the warning on gcc make # change "arch" with the right one # you will be asked a few question there # don't care about the warning on gcc make install arch=Linux_UNKNOWNSSE2 ## Create a new directory where to put the include and lib files ## (root) mkdir /usr/local/lib/atlas ## then copy all the include and archive (*.a) files ## under this new dir cp include/* /usr/local/lib/atlas cp *.a /usr/local/lib/atlas # in .cshrc # and don't forget to set it up, this is for tcsh.
