NOX Configuration Options

Here is a list and explanation of NOX specific configuration options. See the Trilinos User Guide for general options supported by all packages in Trilinos.

To get a complete list of all configure options supported by NOX and LOCA, go to the top-level NOX source directory:

> cd Trilinos/packages/nox

Then run configure's help mode:

> ./configure --help

Basic Options

• --enable-nox-debug
  • This turns on special debugging checks and output in NOX.
• --enable-nox-examples
  • Builds the example code in NOX and LOCA. Overrides the --enable-examples configure flag for the nox package only.
• --enable-nox-tests
  • Builds the tests in NOX and LOCA. Overrides the --enable-tests configure flag for the nox package only.

LAPACK-Related Options

• --enable-nox-lapack
  • Compile noxlapack library (libnoxlapack.a). Default is not to compile the library.

Epetra-Related Options

• --enable-nox-epetra
  • Compile noxepetra library (libnoxepetra.a). Default is not to compile the library.

Thyra-Related Options

• --enable-nox-thyra
  • Compile noxthyra library (libnoxthyra.a). Default is not to compile the library.

PETSc-Related Options

• --enable-nox-petsc
  • Compile noxpetsc library (libnoxpetsc.a). Default is not to compile the library.
  • Requires existing PETSc source specified by environment variables, PETSC_DIR and PETSC_ARCH

  See The PETSc Interface for more information regarding building NOX with PETSc

LOCA-Related Options

• --enable-loca
  • Compile the loca library (libloca.a). Default is not to compile the library. Also compiles appropriate interfaces if they have been enabled (e.g., lapack and epetra).
  • LOCA requires the Trilinos package Teuchos, and Trilinos must be configured with --enable-teuchos to use LOCA.
  • If LAPACK support is enabled, Trilinos must be configured with --enable-teuchos-complex.
• --with-loca-anasazi
  • Enable Anasazi eigensolver support in LOCA.
  • LOCA has a generic interface to Anasazi allowing it to compute eigenvalues/eigenvectors for any group/vector implementation.
  • Trilinos must be configured with --enable-anasazi to use this option.
• --with-loca-mf[=PATH]
  • Enable Multifario support in LOCA.
  • Multifario (MF) is a multi-parameter continuation library written by Mike Henderson at IBM. Including this option allows LOCA to use MF for multi-parameter continuation. Optinally, the path to the top-level Multifario directory can be specified as an argument to this option. The path to the Multifario include directory will then by PATH/include and the path to the Multifario library directory will be PATH/lib.
  • The flags --with-mf-incdir and --with-mf-libdir are also available to point to the MF include and lib directories. A version of MF that is known to work with LOCA is available in the Trilinos3PL.
  • The multifario libraries can be specified with --with-mf-libs. The default is "-lMF -lExpCmp".

Python-Related Options

• --enable-python
  • Enable python interface wrappers in NOX. Default is to not build the python support.
  • If LOCA is enabled, --enable-python also enables the LOCA-python wrappers, and if LAPACK or Epetra support is enabled, those python interface wrappers are enabled as well.
  • The python interface wrappers are generated by SWIG .
  • The wrappers are known to work with python 2.3 and 2.4. For the python-Epetra support, the Numeric module is required, and version 23.3 is known to work.
• --with-swig
  • Enable creation of SWIG wrapper files using SWIG.
  • SWIG is now required to build the python interface files.
  • The path to the SWIG binary can be passed as an optional argument to this flag.
  • Currently SWIG version >= 1.3.23 is required.

Developer-Related Options

• --enable-maintainer-mode
  • Enable make rules and dependencies not useful (and sometimes confusing) to the casual installer
• --enable-prerelease
  • Cannot be used with the distribution version of the code - only works withe CVS version. Compiles code that is not included in the releases but is part of the CVS repository. See NOX Developer's Guide to Prerelease Code.
