• Boost uses bjam for building the boost libs.

  bjam source is available in boost, hence we first need to build bjam itself:

   

  Code Block
  language bash
  cd $BOOST_ROOT ./bootstrap.sh

   

  Now make sure bjam is accessible from $PATH

• Ecflow uses some of compiled libraries in boost. The following script will build the required lib’s, in both debug and release forms and will configure boost build according to your platform.

   

  Code Block
  language bash
  cd $BOOST_ROOT $WK/build_scripts/boost_1_53_fix.sh # fix for boost, only for some platforms $WK/build_scripts/boost_build.sh # compile boost libs used by ecFlow

...

To use the ecFlow Python Api , you need to add/change PYTHONPATH . 

export PYTHONPATH=$PYTHONPATH:/usr/local/apps/ecflow/4.0.8/lib/python2.7/site-packages/ecflow

boost-build/bjam

• Now make sure bjam is accessible from $PATH or use $BOOST_ROOT/bjam  in place bjam below.
• For installation the following environment variables are required.

  ECFLOW_INSTALL_DIR         # Directory Location for client ,server and gui program's
  ECFLOW_PYTHON_INSTALL_DIR  # Directory Location for ecflow python package
          

  The python installation can be customised, by changing Pyext/jamfile.jam and $BOOST_ROOT/tools/build/v2/site-config.jam

• We now need to build ecFlow. Currently ecflowview/GUI is only built if environment variable of name ARCH is set to linux:

  Code Block
  language bash
  cd $WK bjam variant=release

   

  On some systems like fedora/redhat you may run into compiler errors which complain about the template depth being exceeded. In this case compile using:

   

  Code Block
  language bash
  cd $WK bjam c++-template-depth=512 variant=release

   

  If you have a multi-core machine, you can speed up the build using,  the -j<n> option. Where ‘n’ is an integer, of the number of cores.

   

  Code Block
  language applescript
  CPUS=$(lscpu -p | grep -v '#' | wc -l) bjam variant=release -j${CPUS)

• Once ecFlow is built it can be installed.    Note if you used c++-template-depth=512, use it gain for the next step.

   

  Code Block
  language bash
  bjam variant=release install-all

   

  This will create directories:

  Code Block
  <ECFLOW_INSTALL_DIR>/bin <ECFLOW_INSTALL_DIR>/lib <ECFLOW_INSTALL_DIR>/doc <ECFLOW_INSTALL_DIR>/share <ECFLOW_PYTHON_INSTALL_DIR>

  Depending on your umask setting you may need to call chmod 755 on the executables

• To use the ecFlow Python Api , you need to add/change PYTHONPATH . 

   

  Code Block
  language bash
  export PYTHONPATH=$PYTHONPATH:$ECFLOW_PYTHON_INSTALL_DIR

• When compiling ecflowview in a system where motif is not installed in the usual location, or where both motif and lesstif are installed, it is possible to export the environment variables MOTIF_INCLUDE and MOTIF_LIBRARY to help bjam to find the right location for include files and libraries.

  Openmotif may be retrieve from IST server and installed locally: wget http://www.ist-inc.com/motif/download/motif_files/openmotif-2.1.32-2_IST.x86_64.rpm rpm2cpio openmotif-2.1.32-2_IST.x86_64.rpm | cpio -idmv

  user shall then compile setting MOTIF_INCLUDE and MOTIF_LIBRARY variable.
