Hey,

I would like to try your code but have problems building it. I'm using Windows 10 x64 with MS VS 2015, release configuration x64. Following errors occur when I try to build your project:

Hi,

The library builds on pcl library. The code has been developed and tested for ubuntu Linux and gnu Tool chain.

Cheers

Markus

Hi, Did you solve the problem? Thank you!

[JR9124]

Hi, @NatholBMX I have also met the problem as you stated. I try to solve the problem as the following way: I think the main reason caused these link errors is the code pcl::SampleConsensusModelPlane<pcl::PointNormal>::Ptr model_p(new pcl::SampleConsensusModelPlane<pcl::PointNormal>(sv_centroid_normal_cloud)); in segmentation.cpp , thus, I change the code to pcl::PointCloud<pcl::PointXYZ>::Ptr tmp_cloud(new pcl::PointCloud<pcl::PointXYZ>); pcl::copyPointCloud(*sv_centroid_normal_cloud, *tmp_cloud); pcl::SampleConsensusModelPlane<pcl::PointXYZ>::Ptr model_p(new pcl::SampleConsensusModelPlane<pcl::PointXYZ>(tmp_cloud));. I think this change would not change the result as model_p is only for plane hypothesis generation. After the change, you can re-compile then you get the error 'can't find Release\segmentation.lib', while you can find segmentation.dll. To solve this, add a new .def file to segmentation project( right click the project in vs, select 'add->new item->code->module define file', the name of the added file is not important and the file could be deleted afterward if you want ), then re-compile. Note that, the exported dll and lib has no entry, you must change class Segmentation to class __declspec(dllexport) Segmentation in segmentation.hpp. Then re-compile, and you can get the right result.

THX! Your answer is very useful and I successlly compiled already. But why after changing the class pcl::SampleConsensusModelPlane<pcl::PointNormal>to the class pcl::SampleConsensusModelPlane<pcl::PointNormal> the code work? Can u tell me the reason? :)
