安装、编译源代码

下载安装文件

wget https://oceandata.sci.gsfc.nasa.gov/manifest/install_ocssw
wget https://oceandata.sci.gsfc.nasa.gov/manifest/manifest.py

查看代码tag

chmod +x install_ocssw
./install_ocssw --list_tag

创建安装文件夹

mkdir ocssw

安装源代码

./install_ocssw --tag V2025.1 --src --goci --common --install_dir $HOME/ocssw

安装依赖

Ubuntu

sudo apt install cmake gdb git gcc g++ gfortran tcsh bison flex zlib1g-dev libx11-dev pkg-config build-essential cmake libpthread-stubs0-dev unzip -y

设置环境变量

vim ~/.bashrc

在文件末尾添加以下内容

# ocssw config
export OCSSWROOT=$HOME/ocssw
source $OCSSWROOT/ocssw_src/OCSSW_bash.env
export OCSSW_DEBUG=1
export PROJ_DATA=$HOME/PROJ_DATA

编译源代码

cd ocssw/opt/src
./BuildIt.py

编译ocssw_src

cd ocssw/ocssw_src
mkdir build
cd build 
cmake ..
make

VScode配置

首先在VScode中安装所需要的插件

• C/C++
• C/C++ Extension Pack
• C/C++ Themes
• CMake Tools
