通过Clion配置HDF5依赖，并部署在linux服务器中

1. 安装对应版本的cmake

   我安装的是cmake 3.16.3。安装步骤可以参考https://www.cnblogs.com/hans_...。

   cmake安装完之后，可以用ctest --version测试一下是否成功安装了ctest，这个之后的编译环节需要。

   在clion中配置相应的cmake路径，此处应该有很多教程，不再赘述。

2. 安装HDF5相关的文件

   我下载的HDF5 1.10.8版本，下载链接https://confluence.hdfgroup.o...。

   因为我们是在服务器上使用，所以下载CMake-hdf5-1.10.8.tar.gz即可。

   下载压缩包

   wget https://support.hdfgroup.org/ftp/HDF5/releases/hdf5-1.10/hdf5-1.10.8/src/CMake-hdf5-1.10.8.tar.gz

   解压缩这个文件

   tar -zxvf CMake-hdf5-1.10.8.tar.gz

   cd CMake-hdf5-1.10.8

   运行编译脚本

   sh build-unix.sh

   然后会发现当前目录下会多了一个HDF5-1.10.8-Linux.tar.gz文件，对他进行解压缩

   tar -zxvf HDF5-1.10.8-Linux.tar.gz

   不断进入当前文件的子文件中，即(.....)/CMake-hdf5-1.10.8/HDF5-1.10.8-Linux/HDF_Group/HDF5/1.10.8。此时可以看到有bin、include、lib、share文件。其中share文件夹中的cmake文件正是我们需要的。

   在clion中配置一个环境变量（Settings -> Cmake -> Environment -> +），HDF5_DIR => (.....)/CMake-hdf5-1.10.8/HDF5-1.10.8-Linux/HDF_Group/HDF5/1.10.8/share/cmake。

3. 用官网给出的文件测试环境

   此时环境应该就算配置完成，可以使用官网给出的文件进行测试，

   如下是CmakeLists.txt文件

   cmake_minimum_required (VERSION 3.10.2)
   project (myproj C CXX Fortran)
   
   set (FIND_HDF_COMPONENTS C CXX shared)
   
   find_package (HDF5 NAMES "hdf5" COMPONENTS ${FIND_HDF_COMPONENTS})
   if (HDF5_FOUND)
     if (HDF5_shared_C_FOUND)
       set (LINK_LIBS ${LINK_LIBS} ${HDF5_C_SHARED_LIBRARY})
     endif ()
     if (HDF5_shared_CXX_FOUND)
       set (LINK_LIBS ${LINK_LIBS} ${HDF5_CXX_SHARED_LIBRARY})
     endif ()
   else ()
     message (FATAL_ERROR " HDF5 is Required")
   endif ()
   INCLUDE_DIRECTORIES (${HDF5_INCLUDE_DIR})
   
   # Add your application HERE
   add_executable (runapp h5_write.c)
   
   target_link_libraries (runapp PRIVATE ${LINK_LIBS})
   

   如下是h5_write.c文件

   运行h5_write.c文件即可。
