Question

我正在尝试将Point Cloud Library与kinect一起用于论文，但是当我按照this tutorial并尝试在Visual Studio 2010中编译解决方案时，我遇到了一些构建错误：

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)

有人可以解释为什么会出现这些错误以及我如何解决这些错误？非常感谢所有帮助，我总是接受答案！

Answer 1

您可能使用了错误的PCL版本（64位/ 32位）。如果要生成64位CMake项目，请确保为Visual Studio 2010安装64位PCL库。如果您不确定正在使用的PCL版本，可以按照Fraser的建议进行检查。

您可以从here下载正确的PCL库。

Answer 2

我遇到了同样的错误，我找到了解决方法。当您使用cmake时，如果您使用的是64位PCL库，请确保选择Visual Studio 10 win64生成器。我最初使用Visual Studio 10生成器并得到完全相同的错误。当我将它切换到Visual Studio 10 win64生成器时，它就像一个魅力。
