#
# The UFconfig directory and the above packages should all appear in a single
# directory, in order for the Makefile's within each package to find this file.
#
# To enable an option of the form "# OPTION = ...", edit this file and
# delete the "#" in the first column of the option you wish to use.

# Generic configuration
#------------------------------------------------------------------------------

# C compiler and compiler flags:  These will normally not give you optimal
# performance.  You should select the optimization parameters that are best
# for your system.  On Linux, use "CFLAGS = -O3 -fexceptions" for example.
CC = gcc
CFLAGS = -O3

# ranlib, and ar, for generating libraries
RANLIB = ranlib
AR = ar cr

# delete and rename a file
RM = rm -f
MV = mv -f

# Fortran compiler (not normally required)
F77 = f77
F77FLAGS = -O
F77LIB =

# C and Fortran libraries
LIB = -lm

# For compiling MATLAB mexFunctions (MATLAB 7.5)
MEX = mex -O -largeArrayDims -lmwlapack -lmwblas

# For compiling MATLAB mexFunctions (MATLAB 7.3 and 7.4)
# MEX = mex -O -largeArrayDims -lmwlapack

# For MATLAB 7.2 or earlier, you must use one of these options:
# MEX = mex -O -lmwlapack
# MEX = mex -O

# Which version of MAKE you are using (default is "make")
# MAKE = make
# MAKE = gmake

#------------------------------------------------------------------------------
# BLAS and LAPACK configuration:
#------------------------------------------------------------------------------

# UMFPACK and CHOLMOD both require the BLAS.  CHOLMOD also requires LAPACK.
# See Kazushige Goto's BLAS at http://www.cs.utexas.edu/users/flame/goto/ or
# http://www.tacc.utexas.edu/~kgoto/ for the best BLAS to use with CHOLMOD.
# LAPACK is at http://www.netlib.org/lapack/ .  You can use the standard
# Fortran LAPACK along with Goto's BLAS to obtain very good performance.
# CHOLMOD gets a peak numeric factorization rate of 3.6 Gflops on a 3.2 GHz
# Pentium 4 (512K cache, 4GB main memory) with the Goto BLAS, and 6 Gflops
# on a 2.5Ghz dual-core AMD Opteron.

# These settings will probably not work, since there is no fixed convention for
# naming the BLAS and LAPACK library (*.a or *.so) files.

# Using the Goto BLAS:
# BLAS = -lgoto -lgfortran -lgfortranbegin

# This is probably slow ... it might connect to the Standard Reference BLAS:
BLAS = -L$(HOME)/lib/atlas -lf77blas -latlas -lg2c
#LAPACK = -llapack

# The BLAS might not contain xerbla, an error-handling routine for LAPACK and
# the BLAS.  Also, the standard xerbla requires the Fortran I/O library, and
# stops the application program if an error occurs.  A C version of xerbla
# distributed with this software (UFconfig/xerbla/libcerbla.a) includes a
# Fortran-callable xerbla routine that prints nothing and does not stop the
# application program.  This is optional.
# XERBLA = ../../UFconfig/xerbla/libcerbla.a 

# If you wish to use the XERBLA in LAPACK and/or the BLAS instead,
# use this option:
XERBLA = 

# If you wish to use the Fortran UFconfig/xerbla/xerbla.f instead, use this:
# XERBLA = ../../UFconfig/xerbla/libxerbla.a 

#------------------------------------------------------------------------------
# METIS, optionally used by CHOLMOD
#------------------------------------------------------------------------------

# If you do not have METIS, or do not wish to use it in CHOLMOD, you must
# compile CHOLMOD with the -DNPARTITION flag.  You must also use the
# "METIS =" option, below.

# The path is relative to where it is used, in CHOLMOD/Lib, CHOLMOD/MATLAB, etc.
# You may wish to use an absolute path.  METIS is optional.  Compile
# CHOLMOD with -DNPARTITION if you do not wish to use METIS.
METIS_PATH = ../../metis-4.0
METIS = ../../metis-4.0/libmetis.a

# If you use CHOLMOD_CONFIG = -DNPARTITION then you must use the following
# options:
# METIS_PATH =
# METIS =

#------------------------------------------------------------------------------
# UMFPACK configuration:
#------------------------------------------------------------------------------

# Configuration flags for UMFPACK.  See UMFPACK/Source/umf_config.h for details.
#
# -DNBLAS	do not use the BLAS.  UMFPACK will be very slow.
# -D'LONGBLAS=long' or -DLONGBLAS='long long' defines the integers used by
#  		LAPACK and the BLAS (defaults to 'int')
# -DNSUNPERF	do not use the Sun Perf. Library (default is use it on Solaris)
# -DNPOSIX	do not use POSIX routines sysconf and times.
# -DGETRUSAGE	use getrusage
# -DNO_TIMER	do not use any timing routines
# -DNRECIPROCAL	do not multiply by the reciprocal
# -DNO_DIVIDE_BY_ZERO	do not divide by zero
