I am trying to use the Point Cloud Library in conjunction with the kinect

  • 0

I am trying to use the Point Cloud Library in conjunction with the kinect for a paper, but when I followed this tutorial, and tried to compile the solution in Visual Studio 2010, I had a couple of build errors:

pcd_write.obj : error LNK2019: unresolved external symbol "public: int __thiscall pcl::PCDWriter::writeASCII(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,struct sensor_msgs::PointCloud2 const &,class Eigen::Matrix<float,4,1,0,4,1> const &,class Eigen::Quaternion<float,0> const &,int)" (?writeASCII@PCDWriter@pcl@@QAEHABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@ABUPointCloud2@sensor_msgs@@ABV?$Matrix@M$03$00$0A@$03$00@Eigen@@ABV?$Quaternion@M$0A@@8@H@Z) referenced in function "public: virtual int __thiscall pcl::PCDWriter::write(class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > const &,struct sensor_msgs::PointCloud2 const &,class Eigen::Matrix<float,4,1,0,4,1> const &,class Eigen::Quaternion<float,0> const &,bool)" (?write@PCDWriter@pcl@@UAEHABV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@ABUPointCloud2@sensor_msgs@@ABV?$Matrix@M$03$00$0A@$03$00@Eigen@@ABV?$Quaternion@M$0A@@8@_N@Z)

Can someone explain why these errors are occurring and how I can fix them? All help is greatly appreciated and I always accept an answer!

    You are probably using the wrong PCL version (64 bit / 32 bit). If you are generating a 64 bit CMake project, be sure to install 64bit PCL libraries for Visual Studio 2010. If you are unsure about the version of PCL being used, you can check by following the suggestion from Fraser.

    You can download the correct PCL libraries from here.
