Are there any Linux users out there?

I am interested in talking with anyone using LAPACK in a/any Linux environment.

I am particularly interested in the appropriate make.inc entries.

Thanks

Hello,
I downoladed Clapack and installed it succesfully in a Linux SuSe environment with the following make.inc:

####################################################################
#
SHELL = /bin/sh
#
# The machine (platform) identifier to append to the library names
#
PLAT = _LINUX
#
# Modify the CC and CFLAGS definitions to refer to the
# compiler and desired compiler options for your machine. NOOPT
# refers to the compiler options desired when NO OPTIMIZATION is
# selected. Define LOADER and LOADOPTS to refer to the loader and
# desired load options for your machine.
#
CC = gcc
CFLAGS = -funroll-all-loops -O3
LOADER = gcc
LOADOPTS = $(CFLAGS)
NOOPT =
DRVCFLAGS = $(CFLAGS)
F2CCFLAGS = $(CFLAGS)
#
# The archiver and the flag(s) to use when building archive (library)
# If you system has no ranlib, set RANLIB = echo.
#
ARCH = ar
ARCHFLAGS= cr
RANLIB = ranlib
#
# The location of the libraries to which you will link. (The
# machine-specific, optimized BLAS library should be used whenever
# possible.)
#
BLASLIB = ../../blas$(PLAT).a
LAPACKLIB = lapack$(PLAT).a
F2CLIB = ../../F2CLIBS/libF77.a ../../F2CLIBS/libI77.a
TMGLIB = tmglib$(PLAT).a
EIGSRCLIB = eigsrc$(PLAT).a
LINSRCLIB = linsrc$(PLAT).a
##

This is according to the installation guide, and since it seems to work I have made no changes,

I am also using SuSe Linux, however compiling it with
ifort. Below is copy of my make.inc.

Thanks very much for your replies. I notice that both of you use the reference BLAS library and not a machine/complier optimised BALS set.

What is/are the reason(s) for that choice?

Thanks.
