The header-only library seems broken about falconn HOT 1 OPEN

I was facing the same issue. After some digging, I've patched it by moving the last include line from lsh_nn_table.h:

#include "wrapper/cpp_wrapper_impl.h"

to a new file lsh_nn_table_impl.h:

#ifndef __WRAPPER_IMPL_H__
#define __WRAPPER_IMPL_H__

#include "lsh_nn_table.h"
#include "wrapper/cpp_wrapper_impl.h"

#endif

The trick is to include only once per "project" the lsh_nn_table_impl.h file, ideally in one of your cpp files (so the definitions lay in only one object file of your project) and then use lsh_nn_table.h where needed across your project.
