Mac(Catalina)-from source

The install relies on brew. please see https://brew.sh, by default using the apple clang compiler. Alternatively, we can use gnu, but this requires additional steps as we need to build boost ourselves.

• first, install brew. Paste that in a macOS Terminal or Linux shell prompt.

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh )"

• next, install ecflow dependencies

  brew install cmake
  brew install boost
  brew install boost-python3
  brew install openssl
  brew install qt
  brew install figlet # replacement for banner in scripts (i.e. .ecf files)

• clone and place in $HOME/git

  git clone ssh://git@git.ecmwf.int/ecflow/ecflow.git
  git clone ssh://git@git.ecmwf.int/ecsdk/ecbuild.git
  git clone ssh://git@git.ecmwf.int/ecsdk/metabuilder.git  # optional

• build ecflow, and install to ${HOME}/install/ecflow/${version}

  cd $HOME/git/ecflow
  git checkout develop
  sh -x build_scripts/mac.sh make -j8 install # if you make a mistake use: sh -x build_scripts/mac.sh clean make -j8 install # clean will blast build directory 

• Add the following to your .bash_profile

  ecflow_version=$(awk '/^project/ && /ecflow/ && /VERSION/ {for (I=1;I<=NF;I++) if ($I == "VERSION") {print $(I+1)};}' $HOME/git/ecflow/CMakeLists.txt)      
  python_dot_version=$(python3 -c 'import sys;print(sys.version_info[0],".",sys.version_info[1],sep="")')
  export PATH="$PATH:$HOME/install/ecflow/$ecflow_version/bin"
  export PYTHONPATH="$HOME/install/ecflow/$ecflow_version/lib/python${python_dot_version}/site-packages"
  export WK='$HOME/git/ecflow'
  
  # to use the meta builder on MAC:
  export PERM='$HOME/PERM'       
  export SCRATCH='$HOME/SCRATCH'
  export METABUILDER_TESTING=1

• To use the meta builder on mac: Assumes you have updated .bash_profile.

  cd $WK
  # This will kill the server if its already running, then start the server on port 4141
  # Run the metabuilder/develop
  # start the GUI
  sh -x build_scripts/nightly/quick_install.sh

  You will only be able to run the apple_clang compiler in the metabuilder, to use gnu.92 you will need to install/build with this compiler.
