c++ - HDF5 - C++ - 打开文件读取内容失败

Question

我尝试编写一个非常短的脚本来打开一个 hdf5 文件，但它不起作用。

#include <iostream>
#include "H5Cpp.h"

#ifndef H5_NO_NAMESPACE
    using namespace H5;
#endif

const H5std_string FILE_NAME( "testfile.h5" );

int main (void)

{

    H5File openFile( FILE_NAME, H5F_ACC_RDONLY );

}

我很确定我包含了 hdf5 库和包含的路径。 但是尽管如此，我还是从链接器收到了错误消息:

有人可以帮忙吗？ 谢谢!

对于那些使用 CMake 的人，这里有一个例子:

( undefined reference 问题在最后一行解决)

find_package(HDF5 COMPONENTS C CXX HL REQUIRED)
link_directories( ${HDF5_LIBRARY_DIRS} )
include_directories( ${HDF5_INCLUDE_DIRS} )
add_executable( convert_to_hdf5 src/convert_to_hdf5.cpp )
target_link_libraries( convert_to_hdf5 ${HDF5_CXX_LIBRARIES} )
