}


It prints till the line printf("search done in %f seconds\n",difftime (end,start));

and then just hangs. It does not print "2". I need help.

This is the output I get

loading the filetime taken to build the tree =0.000000
time taken to optimize 0.000000 seconds Test insert took 0.000000 seconds
Test find_with_range found 1 candidates.

time take for within range 0.000000 seconds
time take for erase 0.000000 seconds
inserted node in 0.000000 seconds

Test find_with_range found 1 candidates.

search done in 0.000000 seconds

finding the nodes in this search

^C
and thats it . I have to kill it all the time.

_ [code]"Please use code tags"[/code]

_ Learn to debug.
If you are going to put allusive messages everywhere, then use an unbuffered output (stderr) or flush it.
Or better, execute a step by step run through a debugger.

_ Minimize your example.
Remove the code that is not related to the issue
By instance, you ought to remove all that profile code (you should let that to a profiler, by the way)

_ Put some comments.


Also, ¿where could I obtain the kdtree++/kdtree.hpp file?
