Hi Rajashekar,
I tried running the commands you did on a dataset from the SPDLib tutorial and
they worked OK under OS X using the latest version of SPDLib. Unfortunately I
don't have access to a 64 bit windows machine to test.
Would you be able to repeat the commands with the 'LiDAR.las' dataset from the
SPDLib tutorial (you can download from
https://bitbucket.org/petebunting/spdlib-documentation/downloads). This will
help work out if it is a problem with your dataset or the windows version of
SPDLib (which are new and haven't been as well tested as on UNIX-like systems).
If you are also able to test on a 64 bit Windows 7 machine (which I think was
used to build the binaries - Pete or Roberto can you confirm this) that would
be helpful.
Thanks,
Dan
