It would be nice if someone contributed some code to GRASS to enable reading/writing LAS files directly with libLAS instead of using the las2txt/txt2las mechanisms. It'd be much faster. I would happily help any volunteer who takes on the task.

Awesome. I hadn't tested with William's frameworks yet. I will add this to the docs as another alternative.

These warnings are expected.

Some of these might be issues to worry about. Others are not so consequential. We do strive to compile as warning-free as possible, and we compile by default with most of the warning knobs turned on.
