Compilation and Installation

Procedure

Use PuTTY to log in to the server as the root user.
Decompress the ecFlow installation package.
```
tar -xvf ecFlow-5.5.2-Source.tar.gz
```
Decompress the Boost installation package.
```
tar -xvf boost_1_72_0.tar.gz
```

Create 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

Go to the Boost installation directory and build the Boost library.

cd $BOOST_ROOT
export CC=`which clang`
export CXX=`which clang++`
export FC=`which flang`
./bootstrap.sh
./b2 install --prefix=/path/to/ECFLOW_BUILD/boost_1_72_0

Compile the Boost library using ecFlow.
```
$WK/build_scripts/boost_build.sh
```
Go to the directory generated after the ecFlow decompression.
```
cd $WK
```
Create an independent directory for ecFlow.
```
mkdir build
cd build
```

Use the BiSheng Compiler and run the following cmake command:

export CC=`which clang`
export CXX=`which clang++`
export FC=`which flang`
cmake .. -DENABLE_UI=OFF -DENABLE_PYTHON=OFF

Output for the start:

Output for the end:

Perform the compilation.
```
make -j 8
```
Perform the installation.
```
make install
```
