How to install TAO (and PETSc) on Linux

Written by Jason Rennie, January 2005
Developed using TAO 1.7 and PETSc 2.2.1
Tested on Debian Sarge

• Make sure these packages are installed:
  • Debian: atlas3-base atlas3-base-dev gcc g++ g77
  On Debian, you can optionally install mpich and remove --with-mpi=0 below.
  NOTE: Debian has a petsc-dev package, but I couldn't get it to work w/ TAO.
• Choose a location for installation, set DIR in the script below to that location.
• Get PETSc from http://www-unix.mcs.anl.gov/petsc/petsc-2/
• Put petsc-lite.tar.gz in $DIR
• Get TAO from http://www-unix.mcs.anl.gov/tao/
• Put tao-?.?.tar.gz in $DIR
• Run the following script:

  #!/bin/bash
  
  # Directory for installation
  DIR=~/package/tao
  
  export PETSC_DIR=$DIR/petsc
  export PETSC_ARCH=linux-gnu
  export TAO_DIR=$DIR/tao
  export BOPT=O_c++
  
  cd $DIR
  tar xzf petsc-lite.tar.gz
  ln -s petsc-?.?.? petsc
  tar xzf tao-?.?.tar.gz
  ln -s tao-?.? tao
  cd petsc
  ./config/configure.py --with-mpi=0 --with-default-optimization=g --with-default-language=c++ --with-matlab=0 --with-x=0 --with-blocksolve95=0 --with-adic=0 --with-blas-lib=blas-3 --with-lapack-lib=lapack-3
  make all
  make test &> petsc.test.out
  cd ../tao
  make all
  make tao_testexamples &> tao.test.out

• Check petsc.test.out and tao.test.out for errors. Note that you'll see many harmless "Uniprocessor version of MPI can only use one processor" error messages in the TAO out file.
• When you run TAO programs, the PETSC_DIR, PETSC_ARCH and TAO_DIR environment variables must be set. I recommend that you set them in your ~/.login or ~/.bash_profile.
