1.6.1. 安装 HDF5

sudo apt-get install libhdf5-dev

1.6.2. 安装过程

# unzip in the package directory, e.g., $HOME/opt/
cd ~/opt/
wget https://github.com/CGNS/CGNS/archive/refs/tags/v4.3.0.tar.gz
tar -xvaf v4.3.0.tar.gz

# 安装路径为当前路径
cd CGNS-4.3.0
mkdir -p build
cd build
cmake .. -DCGNS_ENABLE_FORTRAN=1 \
-DCMAKE_INSTALL_PREFIX=$HOME/opt/CGNS-4.3.0/opt-gfortran -DCGNS_BUILD_CGNSTOOLS=0

make
make install

# Add environment variables
echo '# CGNS-4.3.0' >> $HOME/.bashrc
echo 'export CGNS_HOME=$HOME/opt/CGNS-4.3.0/opt-gfortran' >> $HOME/.bashrc
echo 'export PATH=$PATH:$CGNS_HOME/bin' >> $HOME/.bashrc
echo 'export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$CGNS_HOME/lib' >> $HOME/.bashrc
echo ' ' >> $HOME/.bashrc
source ~/.bashrc

1.6.3. 安装 CGNS 工具 (Optional)

CGNS 提供了一系列在本地（非集群）查看、编辑 CGNS 文件的工具，需要先安装以下包，再配置 CGNS。

sudo apt-get install libxmu-dev libxi-dev

sudo apt-get install freeglut3
sudo apt-get install tk8.6-dev
sudo apt-get install freeglut3-dev

CGNS library sometimes complains about missing includes and libraries. Most of the time this is either Tk/TCL or OpenGL. This can be solved by installing freeglut3, tk8.6-dev (,freeglut3-dev, if needed). Note that the version of these libraries might be different on your machine.

cd CGNS-4.3.0
cd build
cmake .. -DCGNS_ENABLE_FORTRAN=1 \
-DCMAKE_INSTALL_PREFIX=$HOME/opt/CGNS-4.3.0/opt-gfortran -DCGNS_BUILD_CGNSTOOLS=1

make
make install

If you compiled with -D CGNS_BUILD_CGNSTOOLS=1, you either need to add the binary path to your PATH environmental variable or you can install the binaries system wide. By specifying the installation prefix as shown in the example configure commands above, the binary path is in your PATH environmental variables; without specifying the prefix, the default is a system path, which requires sudo.
