how to fix two build errors

[ghost]

It is good chance for me to know and touch your codes of object_recognition with ppf features. when i tried to build your codes at the environment of Ubuntu 14.04, ros indigo, qtcreator 5 and gcc/g++ 4.9. I got the following errors.

%%%%%%%
/home/USER/catkin_ws/src/object_recognition-master/src/find_function.cpp:-1: error: multiple definition of pcl::PPFHashMapSearch::nearestNeighborSearch(float&, float&, float&, float&, std::vector<std::pair<unsigned long, unsigned long>, std::allocator<std::pair<unsigned long, unsigned long> > >&)' /home/USER/catkin_ws_indigo2/src/object_recognition-master/src/find_function.cpp:-1: error: multiple definition of pcl::PPFHashMapSearch::setInputFeatureCloud(boost::shared_ptr<pcl::PointCloudpcl::PPFSignature const>)'
collect2: error: ld returned 1 exit status
%%%%%%%

don't you mind helping me correcting the errors. i cannot deny that the errors may occur depending on my environment. when i searched the causal factor for them, i could find the next links. i understand that you have encountered the similar problems several years ago. if you know how to fix about them, please tell me the answers.

Hi,

the problem is that you have this function pcl::PPFHashMapSearch::nearestNeighborSearch defined in two different files (maybe in the includes).
The easiest way to correct the problem is to search for the definition of the function in the pcl library and just put it as inline so that you won't find it twice.

I did not update that code since quite some time so I am not 100% sure but probably it is that.
