Hdf5.h编译错误

Question

我试图编译flann，但是当打开hdf5.h文件时，我发现了一些关于创建hdf5.h的错误！打开这个文件时，您可以发现将自己导入代码！#包括“这是如何发生的？！我怎么才能解决这个问题？

这里是hdf5.h链接：

hdf5.h

Answer 1

这条线

#include <hdf5.h>

不引用文件ifself，而是引用另一个文件，该文件的名称通常位于/usr/include或编译器默认的包含文件路径下。

但是，您似乎缺少了hdf5库开发人员文件，其中应该包括/usr/include/hdf5.h。

您可以在这里找到它们：http://www.hdfgroup.org/downloads/index.html或者在操作系统发行版的存储库中找到它们。

Answer 2

我已经安装了libflann并试图编译FLANN手册提供的示例程序，我也面临着同样的问题。

hdf5.h头在不同的开发包版本(在Ubuntu中)下可用，即libhdf5-dev、libhdf5-mpich-dev、libhdf5-openmpi-dev、libhdf5-mpi-dev等，但它们放在各自的包含目录下，如

/usr/include/hdf5/openmpi/hdf5.h
/usr/include/hdf5/mpich/hdf5.h
/usr/include/hdf5/serial/hdf5.h

因此，在编译时，如果以-I /usr/include/hdf5/serial/的形式提供了相关的基本路径，则编译进行得很好。考虑到我选择了hdf5的串行版本，我必须使用相应的库文件libhdf5_serial。因此，编译命令变成：

g++ flann_example.cpp -I /usr/include/hdf5/serial/ -lhdf5_serial

或者，您可以在/usr/include/hdf5.h上创建一个指向/usr/include/hdf5/serial/hdf5.h的软链接。
