Ubuntu 16.04上的PCL（点云库）1.7 LTS构建错误

Question

我更新了Ubuntu版本从14.04 lts到16.04 lts ，并且在构建利用点云库的项目时遇到了问题。 （它曾经在Ubuntu 14.04很好地工作，我建我的项目qtcreator）

的警告消息我是：

warning: libboost_system.so.1.54.0, needed by /usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib/libpcl_common.so, may conflict with libboost_system.so.1.58.0

，并且错误是：

~/main.cpp:-1: error: undefined reference to `pcl::visualization::PCLVisualizer::PCLVisualizer(std::__cxx11::basic_string, std::allocator > const&, bool)'

~/main.cpp:-1: error: undefined reference to `pcl::visualization::PCLVisualizer::setPointCloudRenderingProperties(int, double, std::__cxx11::basic_string, std::allocator > const&, int)'

我可以请参阅libboost_system.so.1.54.0和libboost_system.so.1.58.0之间的冲突，但我该如何解决？

Answer 1

对于从16.04开始建设pcl，请按照这个 tutorial。 但是没有理由不建立PCL 1.8而不是1.7.x，因为它向下兼容。

此外，1.7.2的Jochen Sprieckerhof存储库已过时1.7.2，因为在Ubuntu 16.04中有一个本地repository。你可以简单地做

sudo apt-get update 
sudo apt-get install libpcl-dev 

我建议一个干净的un-并重新安装一个建议的方式。

Answer 2

也许你应该下载此文件PCL-1.8-linux.deb，

并运行此代码：

sudo dpkg -i PCL-1.8-linux.deb.
