point-cloud-library - Ubuntu 16.04 LTS 上的 PCL(点云库)1.7 构建错误

Question

我将 Ubuntu 版本从 14.04 lts 更新到 16.04 lts在构建利用点云库的项目时遇到问题。(它曾经在 Ubuntu 14.04 上运行良好，我使用 qtcreator 构建我的项目)

我收到的警告信息是:

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

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)'

我可以看到 libboost_system.so.1.54.0 和 libboost_system.so.1.58.0 之间存在冲突，但我该如何解决呢？

Answer 1

要在 16.04 上从源代码构建 pcl，请遵循此 tutorial .但是没有理由不构建 PCL 1.8 而不是 1.7.x，因为它向下兼容。

此外，1.7.2 的 Jochen Sprieckerhof 存储库对于 1.7.2 已经过时，因为在 Ubuntu 16.04 中有一个原生的 repository。 .你可以简单地做

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

我建议以其中一种建议的方式完全卸载并重新安装。
