• ecfFlow consists of two tar files i.e.:  
  

  • boost_1_71_0.tar.gz (or any recent boost)

  • ecFlow-5.45.0-Source.tar.gz

    Create a directory for the build:

    Code Block
    language bash
    mkdir /tmp/ecflow_build

    
    

• Copy the the two tar file into this directory, then change directory to /tmp/ecflow_build

• Un-zip then un-tar the two file files:

  Code Block
  language bash
  tar -zxf boost_1_71_0.tar.gz tar -zxf ecFlow-5.45.0-Source.tar.gz

  
  

• You should have two directories created:

  Code Block
  boost_1_71_0 ecFlow-5.45.0-Source

  
  

• Create two environment variables. These are used by some of the scripts:

  Code Block
  export WK=/tmp/ecflow_build/ecFlow-5.45.0-Source export BOOST_ROOT=/tmp/ecflow_build/boost_1_71_0

  
  

• If you have a module system, please ensure that before you start, gcc,cmake,python3,etc are available in $PATH.

  Code Block
  language bash
  module load gnu module load cmake module load python3 module load qt

cd $WK
mkdir build; cd build;

# Go with defaults, will build with CMAKE_BUILD_TYPE=Release and install to /usr/local
cmake .. 

# build release with debug info  
# cmake .. -DCMAKE_BUILD_TYPE=RelWithDebInfo

# Override install prefix 
# cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/apps/ecflow/5.45.0 

# do NOT build the gui.
# cmake .. -DCMAKE_INSTALL_PREFIX=/usr/local/apps/ecflow -DCMAKE_BUILD_TYPE=Release -DENABLE_GUI=OFF

# ignore Wdeprecated-declarations compiler warning messages and do NOT build python api
# cmake .. -DCMAKE_CXX_FLAGS="-Wno-deprecated-declarations"  -DENABLE_PYTHON=OFF

# Use -j option to speed up compilation. Determine number of cpu's
CPUS=$(lscpu -p | grep -v '#' | wc -l)
make -j${CPUS}
make check
make install

...

export PYTHONPATH=$PYTHONPATH:<prefix>/5.45.0/lib/python2.7/site-packages/ecflow
# If you used the default's then <prefix>=/usr/local
# otherwise you should use whatever you entered for -DCMAKE_INSTALL_PREFIX, hence in the examples above we would have:
export PYTHONPATH=$PYTHONPATH:/usr/local/apps/ecflow/5.45.0/lib/python3.6/site-packages/ecflow 

...

cd $WK/build  # change to the build directory
cmake -DCMAKE_INSTALL_PREFIX=/tmp/avi/custom/ecflow/5.45.0 -DCOMPONENT=python -P cmake_install.cmake -- make install  # install python module under /tmp/avi/custom/ecflow/5.45.0

ecflow_ui: Make a list servers accessible to all users

...

• creating a file called servers

• The format of the servers file is very easy:

  Code Block
  title server file format
  <server_name> <machine_name> <port>

  An example might be:

  Code Block
  title servers file
  server machineX 3141 projectX machineabc 4141 exp1 machineabc 4141 mars bigmac 11031

  
  

• Copy this file to CMAKE_INSTALL_PREFIX/share/ecflow/.   This makes the list of servers accessible to all users of ecflow_ui

  Code Block
  cp servers /tmp/avi/custom/ecflow/5.45.0/share/ecflow/.
