```
Run the following command to decompress the ecFlow installation package:
```
tar -xvf ecFlow-5.5.2-Source.tar.gz
```

Run the following commands to create the two environment variables:

export WK=/path/to/ECFLOW_BUILD/ecFlow-5.5.2-Source
export BOOST_ROOT=/path/to/ECFLOW_BUILD/boost_1_72_0

Run the following commands to go to the Boost installation directory and build the Boost library:
```
cd $BOOST_ROOT
./bootstrap.sh
./b2 install --prefix=/path/to/ECFLOW_BUILD/boost_1_72_0
```
Run the following command to compile the Boost library using ecFlow:
```
$WK/build_scripts/boost_build.sh
```
Run the following command to go to the directory generated after decompression:
```
cd $WK
```
Run the following commands to create an independent directory for ecFlow:

cd build
```

Run the following commands to perform compilation and installation:
