PCL LNK2001 unresolved external symbol EuclideanClusterExtraction extract()
I have been getting the following linker error when building with the Point Cloud Library (PCL 1.8.1) in Visual Studio 2017 – not at all sure why:
Error LNK2001 unresolved external symbol "public: void __cdecl pcl::EuclideanClusterExtraction::extract(class std::vector > &)" (?extract@?$EuclideanClusterExtraction@UPointNormal@pcl@@@pcl@@QEAAXAEAV?$vector@UPointIndices@pcl@@V?$allocator@UPointIndices@pcl@@@std@@@std@@@Z)
I found that to get rid of the linker error I needed to include:
#include
Again I am not sure why, and it is not usual to have to include impl/* files? – I may look into it a bit further if I get a chance but for now I am happy that my code links!
