[Liblas-devel] create in internal lab *.exe with Python and Liblas (problem)

[Howard Butler]

Gianni,

If you would like to stay in pure Python, I would suggest using laspy in place of libLAS. It can be used on windows without trouble, and while it might be a little bit slower in some circumstances, it will be much easier to get going with.
