Question

我有特定的要求，我想编译和执行一些具有HDF5依赖关系的代码。我不想使用/* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * Copyright by The HDF Group. * * Copyright by the Board of Trustees of the University of Illinois. * * All rights reserved. * * * * This file is part of HDF5.

It is used in the HDF5 Tutorial. */ #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); }，但我想编译HDF5源代码。

我对如何将HDF5链接到我的C程序非常新。请您详细解释如何操作，这样我就可以使用c编译器执行此程序并链接从here下载的源文件。

示例C程序 -

{
  "queryType":"SQL",
  "query": "CREATE TABLE st.`repo`.`test` AS SELECT * FROM st.`repo`.`unicode_data`"
}

对于编译，必须将-I标志指向HDF5的include目录。对于系统安装，它通常为/usr/include，但有许多变化，具体取决于HDF5是以串行还是并行方式安装，32/64位等。用于链接-L和{{1标志是重要的。 -l应该指向包含HDF5库的-L，.so或.dll文件的目录（同样，可能有变体），而.dylib只是简单地给出库名称-l和其他名称（我相信-lhdf5和-lz几乎总是被使用）。如果您使用高级库，则需要-lm。

检查这些标志的最简单方法是调用

-lhdf5_hl

将列出所有内容。

PS：您可以一步编译和链接（从h5cc -show到可执行文件）或首先编译（.c到.c）然后链接（.o到可执行文件）。在第一种情况下，需要所有.o，-I和-L标记。
