Emanuele, the scipy compiler flags under
http://www.scipy.org/Installing_SciPy/BuildingGeneral work well. However, if you happen to have to use gcc 3.2.3 (e.g. often in Redhat Enterprise editions present), you have to turn off optimization, otherwise lapack doesn't build properly. The correct build flags are then OPTS = -m64 -fPIC (at least that's what worked for me) Regards, Hanno Emanuele Olivetti <[EMAIL PROTECTED]> said: > Ops, sorry for the misleding subject: I wrote ATLAS but I meant LAPACK :) > > Emanuele Olivetti wrote: > > Hi, > > I'm installing numpy on a 2 cpus intel pentium 4 Linux box.
