为 Ubuntu 16.04.6 LTS 安装 pcl 1.8.0 时出错。#error 您的编译器不支持 C++11

我是一名初学者，在安装 PCL v1.8 时遇到了一些问题。

我按照这个问题的说明进行操作： 如何在 Ubuntu 16.04.2 [LTS] 上为 C++ 安装点云库 v1.8 (pcl-1.8.0)？。

pcl当我尝试使用以下命令构建库时，我遇到了以下与编译器相关的问题：

cd pcl-pcl-1.8.0 && mkdir build && cd build
cmake ..
make
sudo make install

终端输出：

[  5%] Built target pcl_octree
[  5%] Built target pcl_io_ply

If you want to use the NxLib without C++11 features, you can define NXLIB_CPP_COMPATIBILITY_MODE before including the NxLib headers. See the manual for more information and problems this might cause.
 #   error Your compiler does not support C++11.

输出：gcc --version

这解决了我的问题。抱歉回复晚了。手动为 gcc5 启用 cpp 11。使用

cmake -D CMAKE_CXX_STANDARD 11 ..

代替

cmake ..
