我尝试编译flann但是在打开hdf5.h文件时我遇到了一些关于创建hdf5.h的错误！打开此文件时，您可以将自己导入代码！ “#include”这是怎么发生的？！我该如何解决这个问题？

这是hdf5.h链接：
答案 0 :(得分：4)
这一行
#include <hdf5.h>
不引用文件ifself，而是指另一个具有相同名称的文件，通常位于/usr/include下，或者编译器的包含文件的默认路径是。
但是您似乎缺少hdf5库开发人员文件，其中应包含/usr/include/hdf5.h
您可以在此处找到它们：http://www.hdfgroup.org/downloads/index.html或在您的操作系统发行版的存储库中找到它们。

我安装了libflann-dev并且正在尝试编译FLANN Manual给出的示例程序，我遇到了同样的问题。
hdf5.h标头在不同的开发包变体（在Ubuntu中）可用，即libhdf5-dev，libhdf5-mpich-dev，libhdf5-openmpi-dev，libhdf5-mpi-dev等，但它们被放置在各自的包含目录下
/usr/include/hdf5/openmpi/hdf5.h
/usr/include/hdf5/mpich/hdf5.h
/usr/include/hdf5/serial/hdf5.h
因此，在编译相关基本路径作为-I /usr/include/hdf5/serial/时，编译顺利进行。鉴于我选择了hdf5的串行版本，我必须使用相应的库文件libhdf5_serial。因此，编译命令变为：
g++ flann_example.cpp -I /usr/include/hdf5/serial/ -lhdf5_serial
或者，可以在/usr/include/hdf5.h处创建指向/usr/include/hdf5/serial/hdf5.h的软链接。
