ANN error when executing make

[anonymous2792]

Hi,

i a getting the following error when trying to make. Any help is appreciated.

Hi, I have a luck by substituting the datatype of the points_per_component from float to ANNcoord. Since ANNcoord is a double datatype, which is similar to float, I assume it would be safe to do so. Summarily, you can take a look at line 1075 on src/acg_localizer_active_search.cc. Change it from: float **points_per_component[ nb_connected_components ]; to: ANNcoord **points_per_component[ nb_connected_components ];

also at line 1091. Change it from: points_per_component[i] = new float*[ nb_points_per_component[i] ]; to points_per_component[i] = new ANNcoord*[ nb_points_per_component[i] ];

I hope it helps
