Options List¶

• msvc_version: [ string ]

  Version of Visual Studio to use. The default is the newest installed version. Specify 12.0 for Visual Studio 2013 or 14.0 for Visual Studio 2015. Windows MSVC only.

  • default: ''

• target_arch: [ string ]

  Target architecture. The default is the same architecture as the installed version of Python. Windows only.

  • default: ''

• toolchain: [ msvc | mingw | intel ]

  The preferred compiler toolchain. Windows only.

  • default: 'msvc'

• CXX: [ string ]

  The C++ compiler to use.

  • default: ''

• CC: [ string ]

  The C compiler to use. This is only used to compile CVODE.

  • default: ''

• prefix: [ /path/to/prefix ]

  Set this to the directory where Cantera should be installed.

  • default: ''

• python_package: [ y | n | full | minimal | none | default ]

  If you plan to work in Python, then you need the full Cantera Python package. If, on the other hand, you will only use Cantera from some other language (for example, MATLAB or Fortran 90/95) and only need Python to process CTI files, then you only need a minimal subset of the package and Cython and NumPy are not necessary. The none option doesn’t install any components of the Python interface. The default behavior is to build the full Python module for whichever version of Python is running SCons if the required prerequisites (NumPy and Cython) are installed. Note: y is a synonym for full and n is a synonym for none.

  • default: 'default'

• python_cmd: [ /path/to/python_cmd ]

  Cantera needs to know where to find the Python interpreter. If the python_cmd option is not set, then the configuration process will use the same Python interpreter being used by SCons.

  • default: ''

• python_prefix: [ /path/to/python_prefix ]

  Use this option if you want to install the Cantera Python package to an alternate location. On Unix-like systems, the default is the same as the prefix option. If the python_prefix option is set to the empty string or the prefix option is not set, then the package will be installed to the system default site-packages directory. To install to the current user’s site-packages directory, use python_prefix=USER.

  • default: ''

• python3_package: [ y | n | full | minimal | none | default ]

  Deprecated synonym for the python_package option. Will be overridden if python_package is set.

  • default: 'default'

• python3_cmd: [ /path/to/python3_cmd ]

  Deprecated synonym for the python_cmd option. Will be overridden if python_cmd is set.

  • default: ''

• python3_prefix: [ /path/to/python3_prefix ]

  Deprecated synonym for the python_prefix option. Will be overridden if python_prefix is set.

  • 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 matlab_toolbox is 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 environment variable, and compile the Fortran 90 interface if one is found.

  • default: 'default'

• FORTRAN: [ /path/to/FORTRAN ]

  The Fortran (90) compiler. If unspecified, the builder will look for a compatible compiler (gfortran, ifort, g95) in the PATH environment variable. Used only for compiling the Fortran 90 interface.

  • default: ''

• FORTRANFLAGS: [ string ]

  Compilation options for the Fortran (90) compiler.

  • default: '-O3'

• coverage: [ yes | no ]

  Enable collection of code coverage information with gcov. Available only when compiling with gcc.

  Build HTML documentation for the C++ interface using Doxygen.

  • default: 'no'

• sphinx_docs: [ yes | no ]

  Build HTML documentation for Cantera using Sphinx.

  • default: 'no'

• sphinx_cmd: [ /path/to/sphinx_cmd ]

  Command to use for building the Sphinx documentation.

  • default: 'sphinx-build'

• system_eigen: [ default | y | n ]

  Select whether to use Eigen from a system installation (y), from a Git submodule (n), or to decide automatically (default). If Eigen is not installed directly into a system include directory — for example, if it is installed in /opt/include/eigen3/Eigen — then you will need to add /opt/include/eigen3 to the extra_inc_dirs option.

  • default: 'default'

• system_fmt: [ default | y | n ]

  Select whether to use the fmt library from a system installation (y), from a Git submodule (n), or to decide automatically (default).

  • default: 'default'

• system_sundials: [ default | y | n ]

  Select whether to use SUNDIALS from a system installation (y), from a Git submodule (n), or to decide automatically (default). Specifying sundials_include or sundials_libdir changes the default to y.

  • 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 such as /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 such as /usr/lib.

  • default: ''

• blas_lapack_libs: [ string ]

  Cantera can use BLAS and LAPACK libraries available on your system if you have optimized versions available (for example, Intel MKL). Otherwise, Cantera will use Eigen for linear algebra support. To use BLAS and LAPACK, set blas_lapack_libs to the the list of libraries that should be passed to the linker, separated by commas — for example, "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. Not needed if the libraries are installed in a standard location such as /usr/lib.

  • 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 (for example, nm libblas.a).

  • default: 'lower'

  Controls whether the LAPACK functions have the string length argument at the end of the argument list (yes) or after each argument (no) in the Fortran libraries.

  • default: 'yes'

• system_googletest: [ unspecified | default | y | n ]

  Select whether to use gtest/gmock from system installation (y), from a Git submodule (n), or to decide automatically (default). Deprecated option, please use googletest instead. This option is suppressed by googletest option.

  • default: 'unspecified'

• googletest: [ 'default' | 'system' | 'submodule' | 'none' ]

  Select whether to use gtest/gmock from system installation (system), from a Git submodule (submodule), to decide automatically (default) or don’t look for gtest/gmock (none) and don’t run tests that depend on gtest/gmock. If this option is set then it suppresses the deprecated system_googletest option.

  • default: 'default'

• env_vars: [ string ]

  Environment variables to propagate through to SCons. Either the string all or a comma separated list of variable names such as LD_LIBRARY_PATH,HOME.

  Additional options passed to each GTest test suite, for example —gtest_filter=*pattern*. Separate multiple options with spaces.

• renamed_shared_libraries: [ yes | no ]

  If this option is turned on, the shared libraries that are created will be renamed to have a _shared extension added to their base name. If not, the base names will be the same as the static libraries. In some cases this simplifies subsequent linking environments with static libraries and avoids a bug with using valgrind with the -static linking flag.

  • default: 'yes'

• versioned_shared_library: [ yes | no ]

  If enabled, create a versioned shared library, with symlinks to the more generic library name, for example libcantera_shared.so.2.4.0 as the actual library and libcantera_shared.so and libcantera_shared.so.2 as symlinks.

  • default: 'no'

• layout: [ standard | compact | debian ]

  The layout of the directory structure. ‘standard’ installs files to several subdirectories under ‘prefix’, for example, $prefix/bin, $prefix/include/cantera, $prefix/lib. This layout is best used in conjunction with ‘prefix’=’/usr/local’. ‘compact’ puts all installed files in the subdirectory defined by ‘prefix’. This layout is best with a prefix like ‘/opt/cantera’. ‘debian’ installs to the stage directory in a layout used for generating Debian packages.

  • default: 'standard'
