 # 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.

 # 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.

 # Custom BLAS:
 BLAS = ${BLLP}
 LAPACK = ${BLLP}

 # 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 = ${BLLP}_plain

 # BLAS = -lblas_plain -lgfortran -lgfortranbegin
 # LAPACK = ${BLLP}

 # 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:

 #
 # -DNBLAS   do not use the BLAS.  UMFPACK will be very slow.

 # -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
