PCL (point cloud library) 1.7 on Ubuntu 16.04 LTS build error

Question

I updated Ubuntu version from 14.04 lts to 16.04 lts and got problems when building projects that utilizes point cloud library. (It used to work well on Ubuntu 14.04 and I build my projects with qtcreator)

The warning messages I have are :

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

and the errors are :

~/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)'

I can see there's conflict between libboost_system.so.1.54.0 and libboost_system.so.1.58.0 but how can I solve it?

Answer 1

For building pcl from source on 16.04, please follow this tutorial. But there is then no reason to not build PCL 1.8 instead of 1.7.x, as it is downward compatible.

In addition the Jochen Sprieckerhof repository for 1.7.2 is outdated for 1.7.2, as in Ubuntu 16.04 there is a native repository. You can simply do

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

I recommend a clean un- and reinstall in one of the proposed ways.

Answer 2

Maybe you should download this file PCL-1.8-linux.deb,

And run this code:

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