如何用HDF5源代码编译c程序?

How to compile c program with HDF5 source code?

我有特定的要求,我想编译和执行一些具有 HDF5 依赖项的代码。 我不想使用 hdf5 compiler,但我想编译 HDF5 源代码。

我对如何将 HDF5 link 加入我的 C 程序还很陌生。请详细解释如何操作,以便我可以使用 c 编译器和 linking 从 here.

下载的源文件来执行该程序

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

int main() {

   hid_t       file_id, dataset_id, dataspace_id;  /* identifiers */
   hsize_t     dims[2];
   herr_t      status;

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

   /* Create the data space for the dataset. */
   dims[0] = 4; 
   dims[1] = 6; 
   dataspace_id = H5Screate_simple(2, dims, NULL);

   /* Create the dataset. */
   dataset_id = H5Dcreate2(file_id, "/dset", H5T_STD_I32BE, dataspace_id, 
                          H5P_DEFAULT, H5P_DEFAULT, H5P_DEFAULT);

   /* End access to the dataset and release resources used by it. */
   status = H5Dclose(dataset_id);

   /* Terminate access to the data space. */ 
   status = H5Sclose(dataspace_id);

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

编译时需要-I标志指向HDF5的include目录。对于系统安装,它通常是 /usr/include,但根据 HDF5 是串行安装还是并行安装、32/64 位等,会有很多变化。对于 linking -L-l 标志是重要的标志。 -L 应该指向包含 HDF5 库的 .so.dll.dylib 文件的目录(同样,可以有变化)并且 -l 只是给出库名称 -lhdf5 和其他名称(我相信 -lz-lm 几乎总是被使用)。如果使用高级库,需要-lhdf5_hl

检查这些标志的最简单方法是调用

h5cc -show

这将列出所有内容。

PS:可以一步编译和link(从.c到可执行文件)或者先编译(.c.o ) 然后 link (.o 到可执行文件)。在第一种情况下,需要所有 -I-L-l 标志。
