#           Cantera Configuration File
#
#  Edit this file to control how Cantera is built. Parameters can be set
#  here, or alternatively environment variables may be set before calling
#  this script.
#
#  The default configuration uses GNU compilers (gcc/g++/g77) and
#  builds as much of Cantera and its language interfaces as it can
#  (e.g. if MATLAB is installed on your system, the MATLAB toolbox
#  will be built automatically, otherwise it will be skipped. On linux
#  or Mac OS X, this default configuration should work, and most
#  likely you don't need to edit this file at all - just run it.
#  
#  NOTE: if you DO make changes to this file, save it with another name
#  so that it will not be overwritten if you update the source
#  distribution. 

#######################################################################


# If you define this to be <prefix>, then instead of running this
# script as ./preconfig --prefix=<prefix> you can just run it as
# ./preconfig
CANTERA_CONFIG_PREFIX=${CANTERA_CONFIG_PREFIX:=""}


#----------------------------------------------------------------------
#         Language Interfaces
#----------------------------------------------------------------------
#
# Cantera has several programming language interfaces. Select the ones
# you want to build. The default is to try to build all language
# interfaces.
#
#
#----------------- Python --------------------------------------------
# 
# In addition to being one of the supported language interfaces,
# Python is used internally by Cantera, both in the build process and
# at run time (to process .cti input files). Therefore, you generally
# need to have Python on your system; if you don't, first install it
# from http://www.python.org before proceeding with the installation
# of Cantera.
#
# 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).

# Set PYTHON_PACKAGE to one of these four strings:
#    full      install everything needed to use Cantera from Python
#    minimal   install only enough to process .cti files
#    none      Don't install  or run any Python scripts during the 
#              build process
#    default   try to do a full installation, but fall back to a minimal
#              one in case of errors

PYTHON_PACKAGE=${PYTHON_PACKAGE:="default"}

# Cantera needs to know where to find the Python interpreter.  If
# PYTHON_CMD is set to "default", then the configuration process will
# look for the Python Interpreter somewhere on your PATH, either as
# 'python2' or as 'python'.  If it is not on the PATH, or has a
# different name, set this to the full path to the Python interpreter.
PYTHON_CMD=${PYTHON_CMD:="default"}

# The Cantera Python interface can be built with either the numarray
# or Numeric packages. Set this to "y" to use Numeric, or anything
# else to use numarray. Using numarray is preferred.
USE_NUMERIC=${USE_NUMERIC:="default"}

# If numarray was installed using the --home option, set this to the
# home directory for numarray.
NUMARRAY_HOME=${NUMARRAY_HOME:=""}

# 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. 
CANTERA_PYTHON_HOME=${CANTERA_PYTHON_HOME:="$HOME/python_modules"}
  
# Set this to 'y' when site packages must be put in system directories
# but Cantera tutorials must be put in user space.  An alternative to
# doing this is to put everything in user space by running this script
# with the 'prefix' option, and defining environment variable PYTHONPATH
# to tell Python where to find the Cantera package.
#
SET_PYTHON_SITE_PACKAGE_TOPDIR=${SET_PYTHON_SITE_PACKAGE_TOPDIR:="n"}

PYTHON_SITE_PACKAGE_TOPDIR=${PYTHON_SITE_PACKAGE_TOPDIR:="/usr/local"} 



#----------- MATLAB --------------------------------------------------

# This variable controls whether the MATLAB toolbox will be built. It
# should be set to one of these strings:
#
#      "default"     the 'configure' script will try to build a simple 
#                    MATLAB MEX file. If this succeeds, BUILD_MATLAB_TOOLBOX
#                    will be set to "y", otherwise it will be set to "n".
#                    
#      "y"           build the MATLAB toolbox.
#      "n"           do not build the MATLAB toolbox, even if MATLAB is 
#                    installed.
#
# Note that you may need to run 'mex -setup' within MATLAB to
# configure it for your C++ compiler before running this script.
BUILD_MATLAB_TOOLBOX=${BUILD_MATLAB_TOOLBOX:="default"}

                             
#----------- Fortran 90/95 --------------------------------------------------

# This variable controls whether the Fortran 90/95 interface will be
# built. It should be set to one of these strings:
#
#      "default"    The 'configure' script will attempt to compile a small
#                   Fortran 90/05 program; if this succeeds, 
#                   BUILD_F90_INTERFACE will be set to "y", and otherwise to "n".
#      "y"          Build the Fortran 90/95 interface.
#      "n"          Do not build the Fortran 90/95 interface, even if a 
#                   Fortran 90/95 compiler is installed.

BUILD_F90_INTERFACE=${BUILD_F90_INTERFACE:="default"}

# The Fortran 90/95 compiler. If set to "default", the script will
# look for a Fortran 90/95 compiler on your system by the name of
# "f95", "gfortran", or "g95".
F90=${F90:="default"}

# Compiler option flags for the Fortran 90/95 compiler. If you are
# using the Absoft or the NAG compiler, additional options specific to
# these compilers will be added automatically, and you do not need to
# specify them here.  Otherwise, add any required compiler-specific
# flags here.
F90FLAGS=${F90FLAGS:='-O3'}

#----------------------------------------------------------------------
#         Customizations / Extensions
#----------------------------------------------------------------------
#
# You can build your own libraries as part of the Cantera build process.
# This allows you to derive your own classes from those provided by 
# Cantera and build them automatically along with the rest of Cantera.
# All you need to do is specify the directory where your source code is
# located. This capability is not yet fully functional, but should work
# for C++ applications.
USER_SRC_DIR="Cantera/user"  # don't change this

# In some cases, extra printing has been put into the code to aid
# in debugging and verification. In order for the printing to occur
# an additional switch must be turned on. However, compilation
# of the printing is affected by the following DEBUG_MODE option.
# This is turned on here by default. However, for a speedier executable
# compilation of these statements may be turned off by setting
# the parameter to "n".
DEBUG_MODE="y"

#----------------------------------------------------------------------
#         Kernel Configuration
#----------------------------------------------------------------------

# If you are only planning to use a portion of Cantera, you may only
# need a stripped-down kernel. Set those features you want enabled to
# 'y', and set those you want to skip to 'n' (actually anything but
# 'y') or comment them out. Some features are dependent on others; for
# example, enabling 'CK' automatically enables KINETICS and THERMO.

# If you only need to use Cantera to evaluate thermodynamic, kinetic,
# and transport properties, it is sufficient to enable only KINETICS
# and TRANSPORT.

# Note: if you are building the full Python interface or the MATLAB
# interface, it is necessary to build the full kernel.

#-----------------------------------------------------------------
#         CVODE / CVODES
#-----------------------------------------------------------------
# 
# Cantera uses the CVODE 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 have sundials, set SUNDIALS_HOME to the directory
# where it is installed, or else put the sundials libraries on the
# library path.  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
#
USE_SUNDIALS=${USE_SUNDIALS:='default'}
SUNDIALS_HOME=${SUNDIALS_HOME:=/usr/local/sundials}

#----------------------------------------------------------------- 
#         BLAS and LAPACK
#-----------------------------------------------------------------
#
# Cantera comes with Fortran 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
# string that should be passed to the linker to link to these
# libraries, and set BLAS_LAPACK_DIR to the directory where these
# libraries are located. Otherwise, leave these lines commented out.
#
#BLAS_LAPACK_LIBS='-llapack -lblas'
#'-llapack -lf77blas -lcblas -latlas'
#BLAS_LAPACK_DIR='/usr/lib'
#
# Note that on Mac OSX, BLAS and LAPACK from the built-in 'Accelerate'
# framework are used by default, and nothing needs to be specified
# here.
#
# The options below do not need to be set if you are using the default
# libraries.
#
# Set to 'lower' or 'upper', depending on whether the procedure names
# in the libraries are lowercase or uppercase. If you don't know, run
# 'nm' on the library file (e.g. 'nm libblas.a') Note that the these options
# apply to both the BLAS and LAPACK libraries. 
LAPACK_NAMES='lower'
LAPACK_FTN_TRAILING_UNDERSCORE='y'

# Currently this must be set to 'y'.
LAPACK_FTN_STRING_LEN_AT_END='y'

#-------------------------------------------------------------------
#      External procedures
#-------------------------------------------------------------------

# Cantera uses several external software packages, which are all in
# the 'ext' directory.. These options control how these packages are
# built.

# For external procedures written in Fortran 77, both the original F77
# source code and C souce code generated by the 'f2c' program are
# included.  Set this to "y" if you want to build Cantera using the
# f2c-generated C sources instead of using the F77 sources in the ext
# directory.

# The default is to use the f2c code.  Set this to "n" to never do
# this on any platform.  Note, if set to "y", Cantera does not need a
# fortran compiler, and all fortran compiler parameters below are
# irrelevant.
