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

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.

car
