PCL 1.8.1+VS2017吐血配置成功
一直在做点云相关内容，虽然PCL库很方便，但配置起来太麻烦了，一开始尝试几次都没有成功，很搞心态。直到今天，还是在生日当天，终于配置成功了呜呜，流下了激动的泪水，这真的是最棒的礼物了，所以马不停蹄的记录一下。
其实其他博客对相关步骤说明的已经很清晰了，但跟着配置下来总会出现各种各样的问题，很大程度上是安装目录、版本等不同导致的，所以要真正明白每一步骤的作用并耐心一一解决出现的bug。
接下来就简要梳理下核心步骤，主要是对整个安装过程有个宏观了解。
一、通过安装包安装PCL
链接：https://pan.baidu.com/s/1vWjaGcr7c1XBSdaSD3FsEg
提取码：o9st
在百度网盘里有PCL1.8.1的安装程序以及PDB文件
其他版本也可在此处下载：Releases · PointCloudLibrary/pcl · GitHub
win10系统下 VS2019点云库PCL1.12.0的安装与配置_苦瓜王子的博客-CSDN博客_pcl库下载
我安装的目录在D:\Program Files\PCL 1.8.1，安装步骤按照弹出的默认来即可，其中以下步骤要勾选第二项添加路径
安装过程中会弹出OpenNI的安装程序，要安装在D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2目录下
全部安装完成后目录文件分布如下所示。
添加PDB文件，将PDB文件解压复制到D:\Program Files\PCL 1.8.1\bin目录下，最终为246个文件。
二、配置电脑环境变量
在计算机属性里的高级系统设置里的环境变量中进行设置。
添加以下内容（最好再和自己的目录对应下，看看这些文件是否都存在）：
D:\Program Files\PCL 1.8.1\bin
D:\Program Files\PCL 1.8.1\3rdParty\FLANN\bin
D:\Program Files\PCL 1.8.1\3rdParty\Qhull\bin
D:\Program Files\PCL 1.8.1\3rdParty\VTK\bin
D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Tools
添加完之后要重启！
三、配置VS2017
在vs2017中添加属性表，在属性表的属性中进行设置。
将以下路径添加到VC++目录的包含目录：
D:\Program Files\PCL 1.8.1\include\pcl-1.8
D:\Program Files\PCL 1.8.1\3rdParty\Boost\include\boost-1_64
D:\Program Files\PCL 1.8.1\3rdParty\Eigen\eigen3
D:\Program Files\PCL 1.8.1\3rdParty\FLANN\include
D:\Program Files\PCL 1.8.1\3rdParty\Qhull\include
D:\Program Files\PCL 1.8.1\3rdParty\VTK\include\vtk-8.0
D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Include
将以下路径添加到VC++目录的库目录：
D:\Program Files\PCL 1.8.1\lib
D:\Program Files\PCL 1.8.1\3rdParty\FLANN\lib
D:\Program Files\PCL 1.8.1\3rdParty\Boost\lib
D:\Program Files\PCL 1.8.1\3rdParty\Qhull\lib
D:\Program Files\PCL 1.8.1\3rdParty\VTK\lib
D:\Program Files\PCL 1.8.1\3rdParty\OpenNI2\Lib
在预处理器定义中输入以下命令：
_SCL_SECURE_NO_WARNINGS
_CRT_SECURE_NO_WARNINGS
如果安装在VS2019版本中，命令如下：
vs2019配置PCL1-8-1（windows）_zh小辣鸡的博客-CSDN博客_pcl vs2019配置
_CRT_SECURE_NO_WARNINGS
BOOST_ALL_NO_LIB
BOOST_USE_WINDOWS_H
NOMINMAX
_SCL_SECURE_NO_WARNINGS
_SILENCE_FPOS_SEEKPOS_DEPRECATION_WARNING
在附加依赖项中添加以下命令，可以自己生成，也可以直接用下方整理好的
（1）自己生成
先把各个库的debug版和release版的lib分别复制到两个不同的文件夹，再通过cmd来生成文件名列表，生成文件名列表的方法如下：
win+r调出“运行”窗口并输出cmd
输入：cd /d D:\ debug_version 回车 （以放debug版的lib文件夹为例）
输出：dir /b *.lib>1.txt
在文件夹下可看见一个txt，打开即可复制。
lib文件所在位置如下，其中debug模式下共有185个文件，release模式下共有186个文件（多了OpenNI2里的OpenNI2.lib），最后需要分别再添加opengl32.lib，可以减少一些隐藏错误。
带-gd的和带d的为debug模式，不带的为release模式。
详细提取文件名步骤参考：PCL安装与配置 - 一杯明月 - 博客园

四、一些问题
在vs2022配置1.13版本
(30条消息) Win10 系统下VisualStudio2022 配置点云库 PCL 1.13.0_胖胖12138的博客-CSDN博客
win+vs2022+pcl 1.13.0 all in one 安装 - 赛博坦的bimer - 博客园 (cnblogs.com)
1.项目解决方案配置需设置为Debug X64
2.遇到“error C4996:pcl::SAC_SAMPLE_SIZE”的解决办法：SDL检查需设置为否
2.遇到“pop_t找不到标识符”的解决办法：打开dist.h文件，将503行的typedef unsigned long long pop_t;移到#if GNUC一行的前面。
3.遇到C2988:“不可识别的模板声明/定义”的解决办法：打开typeof_impl.hpp文件，将以下几行代码注释掉。
4.遇到错误 C4996 ‘std::fpos<_Mbstatet>::seekpos’: warning STL4019: The member std::fpos::seekpos() is non-Standard, and is preserved only for compatibility with workarounds for old versions of Visual C++.的解决办法：
预处理项中添加_SILENCE_FPOS_SEEKPOS_DEPRECATION_WARNING
5.请确认Import中声明的路径是否正确
配置完属性表，在移植时又可能出现不对应的情况
(5条消息) vs未找到导入的项目，请确认
