I am trying to compile a project Kintinuous used pcl-1.7. 我正在尝试编译Kintinuous使用过的pcl-1.7项目。 However I got some errors. 但是我遇到了一些错误。 I am searching for a long time on Google, but I still have no idea. 我在Google上搜索了很长时间，但我仍然不知道。 I am a newcomer to programming. 我是编程的新手。 Please help me. 请帮我。 The errors look like this: 错误看起来像这样：

I had same issue on different library that depends on flann and fixed by https://github.com/mariusmuja/flann/issues/214 我在依赖flann的不同库上有相同的问题，并通过https://github.com/mariusmuja/flann/issues/214修复

We had a mysterious error in the serialization code if we included the flann headers after some opencv headers and used g++ -std=c++11 . 如果在一些opencv标头之后包含flann标头，并使用g++ -std=c++11 ，那么序列化代码中就会出现一个神秘的错误。 Changing the include order fixed the issue (including flann headers before any opencv headers). 更改包含顺序可解决此问题（在所有opencv标头之前包含flann标头）。 It seems that opencv headers leak #define USE_UNORDERED_MAP 1 in case of std ≥ C++11. 在#define USE_UNORDERED_MAP 1 ++ 11的情况下，似乎opencv标头泄漏#define USE_UNORDERED_MAP 1 。 This then gets picked up by the #if in lsh_table.h in the original flann library. 然后由原始flann库中的lsh_table.h中的#if拾取。

The solution is to include flann before OpenCV. 解决方案是在OpenCV之前加入flann。
