scons: Reading SConscript files ...

        **************************************************
        *   Configuration options for building Cantera   *
        **************************************************

The following options can be passed to SCons to customize the Cantera
build process. They should be given in the form:

    scons build option1=value1 option2=value2

Variables set in this way will be stored in the 'cantera.conf' file
and reused automatically on subsequent invocations of
scons. Alternatively, the configuration options can be entered
directly into 'cantera.conf' before running 'scons build'. The format
of this file is:

    option1 = 'value1'
    option2 = 'value2'

        **************************************************

* msvc_version: [ string ]
    Version of Visual Studio to use. The default is the same version
    that was used to compile the installed version of Python.
    - default: '9.0'

* target_arch: [ string ]
    Target architecture. The default is the same architecture as the
    installed version of Python
    - default: 'amd64'

* toolchain: [ msvc | mingw | intel ]
    The preferred compiler toolchain.
    - default: 'msvc'

* CXX: [ string ]
    The C++ compiler to use.
    - default: 'g++'

* CC: [ string ]
    The C compiler to use. This is only used to compile CVODE and the
    Python extension module.
    - default: 'gcc'

* prefix: [ /path/to/prefix ]
    Set this to the directory where Cantera should be installed.
    - default: '/usr/local'

* python_package: [ full | minimal | none | default ]
    If you plan to work in Python, or you want to use the graphical
    MixMaster application, then you need the 'full' Cantera Python
    Package. If, on the other hand, you will only use Cantera from some
    other language (e.g. MATLAB or Fortran 90/95) and only need Python
    to process .cti files, then you only need a 'minimal' subset of the
    package (actually, only one file). The default behavior is to build
    the Python package if the required prerequisites (numpy) are
    installed.
    - default: 'default'

* python_cmd: [ /path/to/python_cmd ]
    Cantera needs to know where to find the Python interpreter. If
    PYTHON_CMD is not set, then the configuration process will use the
    same Python interpreter being used by SCons.
    - default: '/usr/bin/python'

* python_array: [ numpy | numarray | numeric ]
    The Cantera Python interface requires one of the Python array
    packages listed. Support for the legacy 'numeric' and 'numarray'
    packages is deprecated, and will be removed in a future version of
    Cantera.
    - default: 'numpy'

* python_array_home: [ /path/to/python_array_home ]
    If numpy was installed using the --home option, set this to the home
    directory for numpy.
    - default: ''

* python_prefix: [ /path/to/python_prefix ]
    If you want to install the Cantera Python package somewhere other
    than the default 'site-packages' directory within the Python library
    directory, then set this to the desired directory. This is useful
    when you do not have write access to the Python library directory.
    - default: ''

* matlab_toolbox: [ y | n | default ]
    This variable controls whether the Matlab toolbox will be built. If
    set to 'y', you will also need to set the value of the 'matlab_path'
    variable. If set to 'default', the Matlab toolbox will be built if
    'matlab_path' is set.
    - default: 'default'

* matlab_path: [ /path/to/matlab_path ]
    Path to the Matlab install directory. This should be the directory
    containing the 'extern', 'bin', etc. subdirectories. Typical values
    are: "C:/Program Files/MATLAB/R2011a" on Windows,
    "/Applications/MATLAB_R2011a.app" on OS X, or "/opt/MATLAB/R2011a"
    on Linux.
    - default: ''

* f90_interface: [ y | n | default ]
    This variable controls whether the Fortran 90/95 interface will be
    built. If set to 'default', the builder will look for a compatible
    Fortran compiler in the $PATH, and compile the Fortran 90 interface
    if one is found.
    - default: 'default'

* F90: [ /path/to/F90 ]
    The Fortran 90 compiler. If unspecified, the builder will look for a
    compatible compiler (gfortran, ifort, g95) in the $PATH.
    - default: ''

* F90FLAGS: [ string ]
    Compilation options for the Fortran 90 compiler.
    - default: '-O3'

    Cantera format (.cti). If you don't use Chemkin format files, or if
    you run ck2cti on some other machine, you can set this to 'n'.
    - default: 'yes'

* with_kinetics: [ yes | no ]
    Enable homogeneous kinetics.

    Enable ODE integrators and DAE solvers
    - default: 'yes'

* with_html_log_files: [ yes | no ]
    write HTML log files. Some multiphase equilibrium procedures can
    write copious diagnostic log messages. Set this to 'n' to disable
    this capability. (results in slightly faster equilibrium
    calculations)
    - default: 'yes'

* use_sundials: [ default | y | n ]
    Cantera uses the CVODE or CVODES ODE integrator to time-integrate
    reactor network ODE's and for various other purposes. An older
    version of CVODE comes with Cantera, but it is possible to use the
    latest version as well, which now supports sensitivity analysis
    (CVODES). CVODES is a part of the 'sundials' package from Lawrence
    Livermore National Laboratory. Sundials is not distributed with
    Cantera, but it is free software that may be downloaded and
    installed separately. If you leave USE_SUNDIALS = 'default', then it
    will be used if you have it, and if not the older CVODE will be
    used. Or set USE_SUNDIALS to 'y' or 'n' to force using it or not.
    Note that sensitivity analysis with Cantera requires use of
    sundials. See: http://www.llnl.gov/CASC/sundials
    - default: 'default'

* sundials_include: [ /path/to/sundials_include ]
    The directory where the Sundials header files are installed. This
    should be the directory that contains the "cvodes", "nvector", etc.
    subdirectories. Not needed if the headers are installed in a
    standard location, e.g. /usr/include.
    - default: ''

* sundials_libdir: [ /path/to/sundials_libdir ]
    The directory where the sundials static libraries are installed. Not
    needed if the libraries are installed in a standard location, e.g.
    /usr/lib.
    - default: ''

* blas_lapack_libs: [ string ]
    Cantera comes with Fortran (or C) versions of those parts of BLAS
    and LAPACK it requires. But performance may be better if you use a
    version of these libraries optimized for your machine hardware. If
    you want to use your own libraries, set blas_lapack_libs to the the
    list of libraries that should be passed to the linker, separated by
    commas, e.g. "lapack,blas" or "lapack,f77blas,cblas,atlas".
    - default: ''

* blas_lapack_dir: [ /path/to/blas_lapack_dir ]
    Directory containing the libraries specified by 'blas_lapack_libs'.
    - default: ''

* lapack_names: [ lower | upper ]
    Set depending on whether the procedure names in the specified
    libraries are lowercase or uppercase. If you don't know, run 'nm' on
    the library file (e.g. 'nm libblas.a').
    - default: 'lower'

* lapack_ftn_trailing_underscore: [ yes | no ]
    - default: 'yes'

* lapack_ftn_string_len_at_end: [ yes | no ]
    - default: 'yes'

    Compiler and linker flags for POSIX multithreading support
    - default: '-pthread'

* optimize: [ yes | no ]
    Enable extra compiler optimizations specified by the
    "optimize_flags" variable, instead of the flags specified by the
    "debug_flags" variable
    - default: 'yes'

* optimize_flags: [ string ]
    Additional compiler flags passed to the C/C++ compiler when
    optimize=yes.
    - default: '-O3 -DNDEBUG -finline-functions -Wno-inline'

    - default: ''

* build_thread_safe: [ yes | no ]
    Cantera can be built so that it is thread safe. Doing so requires
    using procedures from the Boost library, so if you want thread
    safety then you need to get and install Boost (http://www.boost.org)
    if you don't have it. This is turned off by default, in which case
    Boost is not required to build Cantera.
    - default: 'no'

* boost_inc_dir: [ /path/to/boost_inc_dir ]
    Location of the Boost header files
    - default: '/usr/include'

* boost_thread_lib: [ string ]
    The name of the Boost.Thread library.
    - default: 'boost_thread'

* build_with_f2c: [ yes | no ]
    For external procedures written in Fortran 77, both the original F77
    source code and C source code generated by the 'f2c' program are
    included. Set this to "n" if you want to build Cantera using the F77
    sources in the ext directory.
    - default: 'yes'

    Compiler used to build the external Fortran 77 procedures from the
    Fortran source code
    - default: 'gfortran'

    are using.
    - default: '-O3'

* stage_dir: [ /path/to/stage_dir ]
     Directory relative to the Cantera source directory to be used as a
    staging area for building e.g. a Debian package. If specified,
    'scons install' will install files to 'stage_dir/prefix/...' instead
    of installing into the local filesystem.
    - default: ''

* legacy_headers: [ yes | no ]
    Create symbolic links for headers that were installed to the
    'kernel' subdirectory in previous versions of Cantera.
    - default: 'no'

* graphvisdir: [ /path/to/graphvisdir ]
    The directory location of the graphviz program, dot. dot is used for
    creating the documentation, and for making reaction path diagrams.
    If "dot" is in your path, you can leave this unspecified. NOTE:
    Matlab comes with a stripped-down version of 'dot'. If 'dot' is on
    your path, make sure it is not the Matlab version!
    - default: ''

* rpfont: [ string ]
    The font to use in reaction path diagrams. This must be a font name
    recognized by the 'dot' program. On linux systems, this should be
    lowercase 'helvetica'.
    - default: 'Helvetica'

* cantera_version: [ string ]
    - default: '2.0.0b1'
