VS 2022配置HDF5文件

下载HDF5文件

可以去官网下载https://www.hdfgroup.org/downloads/hdf5/?1685947943，也可以直接用我的百度云链接链接：https://pan.baidu.com/s/1If9QpER6DS2JbhSO2Ec2ug 提取码：1958

配置环境

记住自己的文件所在目录，我这边是D:\hdf5
VC++目录 —> 包含目录 添加 D:\hdf5\include;

VC++目录 —> 库目录 添加 D:\hdf5\lib;

连接器 —> 输入 —> 附加依赖项
添加szip.lib;zlib.lib;hdf5.lib;hdf5_cpp.lib;

C/C++ —> 预处理器 —> 预处理器定义
添加H5_BUILT_AS_DYNAMIC_LIB

D:\hdf5\HDF5Examples\C\H5D\h5ex_d_rdwr.c

/************************************************************

  This example shows how to read and write data to a
  dataset.  The program first writes integers to a dataset
  with dataspace dimensions of DIM0xDIM1, then closes the
  file.  Next, it reopens the file, reads back the data, and
  outputs it to the screen.

  This file is intended for use with HDF5 Library version 1.8
