我对要编译和执行一些具有HDF5依赖关系的代码有特定的要求。
我不想使用hdf5 compiler
,但是我想编译HDF5源代码。
我对如何将HDF5链接到我的C程序非常陌生。请您详细说明如何执行此操作,以便我可以使用c编译器并链接从here下载的源文件来执行此程序。
示例C程序-

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);
}
最佳答案
为了进行编译,必须使-I
标志指向HDF5的include目录。对于系统安装,通常为/usr/include
,但根据以串行或并行方式,32/64位等方式安装HDF5,会有很多变化。对于链接-L
和-l
标志是重要的。 -L
应该指向包含HDF5库的.so
,.dll
或.dylib
文件的目录(同样,可能会有变化),而-l
只是给出了库名,-lhdf5
和其他名称(我相信-lz
和-lm
几乎总是使用)。如果使用高级库,则需要-lhdf5_hl
。
检查这些标志的最简单方法是调用
h5cc -show
它将列出所有这些。
PS:您可以在一个步骤中进行编译和链接(从
.c
到可执行文件),也可以先编译(从.c
到.o
),然后链接(从.o
到可执行文件)。在第一种情况下,需要所有-I
,-L
和-l
标志。关于c++ - 如何用HDF5源代码编译C程序?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/43151312/
