<br>
Unfortunatly, our Windows system configuration prevents me to setup a<br>
msvc build toolchain so I will wait for the next release on this point.<br>
<br>
About the LAS missing signature, for now entwine build seems to be the<br>
only tool blocked by it as I have been using many pdal tools an others<br>
(lastools, cloudcompare, fme, potreeconverter) in the last past weeks.<br>
My first reaction was to convert the las files to laz using pdal<br>
stating minor_version=4 in the hope it would automagically solves it.<br>
<br>
