'configure' configures $sysname ${version}p${versionp} to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Those variables can be set in the shell to affect all future invocations
of $0.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--ignore-envs ignore variables set in the shell
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
For better control, use the options below.
Fine tuning of the installation directories:
--libdir=DIR installation directory [OCAML]
--stubdir=DIR stub installation directory [OCAML/stublibs]
--docdir=DIR documentation [PREFIX/share/doc/sundialsml]
Optional Features:
--disable-doc do not install html documentation
--disable-mpi build without parallel features
--disable-openmp build without OpenMP features
--disable-klu build without KLU features
--disable-superlumt build without SuperLU/MT features
--no-lib-path do not record paths in the OCaml library
--enable-debug enable assertions and debug symbols
--unsafe no bounds or other runtime checks
Influential environment variables:
OCAMLROOT Path to OCaml installation
SUNDIALS_DIR Path to Sundials installation
SUNDIALS_LIBRARY_DIR Path to Sundials libraries (for linking)
(default: \$SUNDIALS_DIR/lib)
SUNDIALS_INCLUDE_DIR Path to Sundials header files (for compiling)
(default: \$SUNDIALS_DIR/include)
SUPERLUMT_DIR Path to SuperLU_MT build files
SUPERLUMT_INCLUDE_DIR Path to SuperLU_MT header files
(default: \$SUPERLUMT_DIR/SRC)
SUPERLUMT_LIBRARY_DIR Path to SuperLU_MT libraries
(default: \$SUPERLUMT_DIR/lib)
KLU_INCLUDE_DIR Path to KLU (SuiteSparse) header files
KLU_LIBRARY_DIR Path to KLU (SuiteSparse) libraries
LAPACKLIB Command for linking with Lapack (default: -llapack)
(sometimes also: -lSimTKlapack)
SUNDIALS_EXAMPLES_DIR Path to installed examples (for comparison with Sundials)
(default: \$SUNDIALS_DIR/examples)
OCAMLMPI Path to OCamlMPI installation
CFLAGS_OPENMP Compiler flag to enable OpenMP compilation
MPICC Name of the MPI compiler (default: mpicc)
MPIRUN Name of MPI program launcher (default: mpirun)
MPI_LIBRARY_DIR Path to include for MPI libraries (optional)
MATHJAX Local or remote directory containing MathJax.js
(e.g., MATHJAX=/usr/share/javascript/mathjax)
OCAML_GRAPHICS Path to OCaml graphics library (for some examples)
Set these options by passing arguments of the form FOO=value to help
configure find libraries and programs with nonstandard names/locations.
