# SuiteSparse_config.mk:  common configuration file for the SuiteSparse
#===============================================================================

# This file contains all configuration settings for all packages authored or
# co-authored by Tim Davis:
#
# Package Version       Description
# ------- -------       -----------
# AMD	  1.2 or later  approximate minimum degree ordering
# COLAMD  2.4 or later  column approximate minimum degree ordering
# CCOLAMD 1.0 or later  constrained column approximate minimum degree ordering
# CAMD    any		constrained approximate minimum degree ordering
# UMFPACK 4.5 or later	sparse LU factorization, with the BLAS
# CHOLMOD any		sparse Cholesky factorization, update/downdate
# KLU	  0.8 or later  sparse LU factorization, BLAS-free
# BTF	  0.8 or later  permutation to block triangular form
# LDL	  1.2 or later	concise sparse LDL'
# CXSparse any		extended version of CSparse (int/long, real/complex)
# SuiteSparseQR	any	sparse QR factorization
# RBio    2.0 or later  read/write sparse matrices in Rutherford-Boeing format
#
# By design, this file is NOT included in the CSparse makefile.
# That package is fully stand-alone.  CSparse is primarily for teaching;
# production code should use CXSparse.
#
# The SuiteSparse_config 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.
#
# The use of METIS 4.0.1 is optional.  To exclude METIS, you must compile with
# CHOLMOD_CONFIG set to -DNPARTITION.  See below for details.  However, if you
# do not have a metis-4.0 directory inside the SuiteSparse directory, the
# */Makefile's that optionally rely on METIS will automatically detect this
# and compile without METIS.

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

# Using standard definitions from the make environment, typically:
#
#   CC              cc      C compiler
#   CXX             g++     C++ compiler
#   CFLAGS          [ ]     flags for C and C++ compiler
#   CPPFLAGS        [ ]     flags for C and C++ compiler
#   TARGET_ARCH     [ ]     target architecture
#   FFLAGS          [ ]     flags for Fortran compiler
#   RM              rm -f   delete a file
#   AR              ar      create a static *.a library archive
#   ARFLAGS         rv      flags for ar
#   MAKE            make    make itself (sometimes called gmake)
#
# You can redefine them here, but by default they are used from the
# default make environment.

# C and C++ compiler flags.  The first three are standard for *.c and *.cpp
# Add -DNTIMER if you do use any timing routines (otherwise -lrt is required).
# CF = $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -O3 -fexceptions -fPIC -DNTIMER
  CF = $(CFLAGS) $(CPPFLAGS) $(TARGET_ARCH) -O3 -fexceptions -fPIC -DNTIMER

# ranlib, and ar, for generating libraries.  If you don't need ranlib,
# just change it to RANLAB = echo
AR = @AR@
RANLIB = @RANLIB@
ARFLAGS =@ARFLAGS@

ARCHIVE = $(AR) $(ARFLAGS)

# copy and delete a file
CP = cp -f
MV = mv -f

# Fortran compiler (not required for 'make' or 'make library')
F77 = gfortran
F77FLAGS = $(FFLAGS) -O
F77LIB =

# C and Fortran libraries.  Remove -lrt if you don't have it.
  LIB = -lm
# Using the following requires CF = ... -DNTIMER on POSIX C systems.
# LIB = -lm

# For "make install"
INSTALL_LIB = @abs_srcdir@/3rdparty/lib
INSTALL_INCLUDE = @abs_srcdir@/3rdparty/include

# 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.

# This is probably slow ... it might connect to the Standard Reference BLAS:
BLAS = @BLASLIBS@
LAPACK = @LAPACKLIBS@

# NOTE: this next option for the "Goto BLAS" has nothing to do with a "goto"
# statement.  Rather, the Goto BLAS is written by Dr. Kazushige Goto.
# Using the Goto BLAS:
# BLAS = -lgoto -lgfortran -lgfortranbegin
# BLAS = -lgoto2 -lgfortran -lgfortranbegin -lpthread

# Using non-optimized versions:
# BLAS = -lblas_plain -lgfortran -lgfortranbegin
# LAPACK = -llapack_plain

# BLAS = -lblas_plain -lgfortran -lgfortranbegin
# 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 (SuiteSparse_config/xerbla/libcerbla.a)
# includes a Fortran-callable xerbla routine that prints nothing and does not
# stop the application program.  This is optional.

# XERBLA = ../../SuiteSparse_config/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 SuiteSparse_config/xerbla/xerbla.f instead,
# use this:

# XERBLA = ../../SuiteSparse_config/xerbla/libxerbla.a

#------------------------------------------------------------------------------

# no cuda

# GPU_CONFIG=-DGPU_BLAS -I$(GPU_BLAS_PATH)/include

#------------------------------------------------------------------------------
# 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.

# 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

#------------------------------------------------------------------------------
# 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)
# -DNRECIPROCAL	do not multiply by the reciprocal
# -DNO_DIVIDE_BY_ZERO	do not divide by zero
# -DNCHOLMOD    do not use CHOLMOD as a ordering method.  If -DNCHOLMOD is
#               included in UMFPACK_CONFIG, then UMFPACK  does not rely on
#               CHOLMOD, CAMD, CCOLAMD, COLAMD, and METIS.
