c - hdf5 示例代码 h5_rdwt.c 不起作用

Question

我在运行来自 hdf5 的示例代码 h5_rdwt.c(在 eclipse 中)时遇到问题。你可以在这里找到这个:

http://www.hdfgroup.org/HDF5/Tutor/rdwt.html#rdwr

代码是:

/*

 */

#include "hdf5.h"
#define FILE "dset.h5"

int main() {

   hid_t       file_id, dataset_id;  /* identifiers */
   herr_t      status;
   int         i, j, dset_data[4][6];

   /* Initialize the dataset. */
   for (i = 0; i < 4; i++)
      for (j = 0; j < 6; j++)
         dset_data[i][j] = i * 6 + j + 1;

   /* Open an existing file. */
   file_id = H5Fopen(FILE, H5F_ACC_RDWR, H5P_DEFAULT);

   /* Open an existing dataset. */
   dataset_id = H5Dopen2(file_id, "/dset", H5P_DEFAULT);

   /* Write the dataset. */
   status = H5Dwrite(dataset_id, H5T_NATIVE_INT, H5S_ALL, H5S_ALL, H5P_DEFAULT, 
                     dset_data);

   status = H5Dread(dataset_id, H5T_NATIVE_INT, H5S_ALL, H5S_ALL, H5P_DEFAULT, 
                    dset_data);

   /* Close the dataset. */
   status = H5Dclose(dataset_id);

   /* Close the file. */
   status = H5Fclose(file_id);
}

在我这样做之前，我创建了一个名为“dset.h5”的文件:

#include "hdf5.h"
#define FILE "dset.h5"

main() {

   hid_t       file_id;   /* file identifier */
   herr_t      status;

   /* Create a new file using default properties. */
   file_id = H5Fcreate(FILE, H5F_ACC_TRUNC, H5P_DEFAULT, H5P_DEFAULT);

   /* Terminate access to the file. */
   status = H5Fclose(file_id);
}

构建没有问题，但是当我尝试运行它时，我收到消息:

有人知道哪里出了问题吗？ 谢谢!

Answer 1

程序中的主例程包括以下行

/* Open an existing dataset. */
dataset_id = H5Dopen2(file_id, "/dset", H5P_DEFAULT);

但是您发布的内容没有证据表明有问题的文件包含任何要打开的数据集。您似乎创建了一个名为 dset 的文件，但这与数据集不同。根据您发布的内容，您的文件是空的。

错误报告中给出了这方面的线索，其中指出，特别是
