Part-3: Install and Configure PCL 1.8.1 with vtk qt support on Ubuntu 16.04 from source

Series

• Part-1: Install and Configure Qt5 on Ubuntu 16.04
• Part-2: Install and Configure VTK 8.1.0 from source with Qt5 on Ubuntu 16.04
• Part-3: Install and Configure PCL 1.8.1 with vtk qt support on Ubuntu 16.04 from source
• Part-4: Install and Configure PCL 1.8.1 with vtk qt support on windows 10 from source

Guide

• qt: 5.7.0
• qmake: 3.0
• qtcreator: 3.5.1
• vtk: 8.1.0 (source)
• pcl :1.8.1 (source)

Setup Prerequisites

 sudo apt-get update
 sudo apt-get install git build-essential linux-libc-dev
 sudo apt-get install cmake cmake-gui 
 sudo apt-get install libusb-dev libudev-dev
 sudo apt-get install mpi-default-dev openmpi-bin openmpi-common 
 
 sudo apt-get install libpcap-dev
 sudo apt-get install libflann1.8 libflann-dev
 sudo apt-get install libeigen3-dev
 sudo apt-get install libopenni2-dev
 sudo apt-get install libqhull7 libqhull-dev 
 
 sudo apt-get install freeglut3-dev pkg-config
 sudo apt-get install libxmu-dev libxi-dev 
 sudo apt-get install mono-complete
 sudo apt-get install openjdk-8-jdk openjdk-8-jre

dropped

 sudo apt-get install qt-sdk 
 sudo apt-get install libvtk5.10-qt4 libvtk5.10 libvtk5-dev
 sudo apt-get install vtk6 libvtk6-dev libvtk6-qt-dev 
 

Notice for vtk version.

metslib

for cmake error:

no metslib found.

fix by

wget https://www.coin-or.org/download/source/metslib/metslib-0.5.3.tgz
tar xzvf metslib-0.5.3.tgz
cd metslib-0.5.3
./configure
make 
sudo make install

glxinfo

install

sudo apt-get install mesa-utils
glxinfo 

possible error

X Error of failed request:  BadRequest (invalid request code or no such operation)
Major opcode of failed request:  154 (GLX)
Minor opcode of failed request:  34 ()
Serial number of failed request:  34
Current serial number in output stream:  33

fix,make sure NVIDIA drivers are installed successfully and no conflict.

check display OpenGL info

$ glxinfo | grep OpenGL

OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 1060/PCIe/SSE2
OpenGL core profile version string: 4.5.0 NVIDIA 384.90
OpenGL core profile shading language version string: 4.50 NVIDIA
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.5.0 NVIDIA 384.90
OpenGL shading language version string: 4.50 NVIDIA
OpenGL context flags: (none)
OpenGL profile mask: (none)
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 384.90
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20
OpenGL ES profile extensions:

It means we use OpenGL version 4.5.0 for NVIDIA display.

Or by nvidia-settings, NVIDIA X Server Settings–> X Screen 0 –> OpenGL/GLX Information.

compile

wget https://github.com/PointCloudLibrary/pcl/archive/pcl-1.8.1.tar.gz

 cd pcl
 mkdir build
 cd build
 cmake-gui ..
 

with options

 QT_USE_FILE /home/kezunlin/program/pcl-1.8.1/build/use-qt5.cmake
 
 VTK_DIR  /usr/local/lib/cmake/vtk-8.1
 
 CMAKE_BUILD_TYPE       Release
 CMAKE_CONFIGURATION_TYPES Release
 CMAKE_INSTALL_PREFIX  /usr/local
 
 PCL_SHARED_LIBS       ON
 PCL_QT_VERSION        5
 PCL_ENABLE_SSE        ON
 
 Build_visualization ON
 Build_apps ON
 Build_examples OFF # error may occur

Using CPU native flags for SSE optimization: -march=native

make and install

 # it may take several minutes, wait ...
 make -j8
 sudo make -j8 install

cmake install to /usr/local/bin, /usr/local/lib/, /usr/local/include/pcl-1.8
PCL_DIR will be /usr/local/share/pcl-1.8

error for example

/home/kezunlin/program/pcl-1.8.1/examples/segmentation/example_cpc_segmentation.cpp:493:17: error:‘class vtkUnsignedCharArray’has no member named‘InsertNextTupleValue’colors->InsertNextTupleValue (color);

so cmake with options

Build_examples OFF

Test pcl_viewer

test pcl_viewer

/usr/local/bin/pcl_viewer ~/program/pcl-1.8.1/test/car6.pcd

Success.
