Nils, Thanks... that solved the problem. Much appreciated! Rudolph On 3/16/06, Nils Wagner <nwagner@mecha.uni-stuttgart.de> wrote:

Did you use

(two lines of make.inc)

to compile lapack ?

Also I have added -m64 -fPIC to some lines in the ATLAS generated makefile ( Make.Linux_HAMMER64SSE3)

F77 = /usr/bin/g77 F77FLAGS = -fomit-frame-pointer -O -m64 -fPIC FLINKER = $(F77) FLINKFLAGS = $(F77FLAGS) FCLINKFLAGS = $(FLINKFLAGS)
