site (<a href="https://github.com/LASzip/LASzip" target="_blank">https://github.com/LASzip/LASzip</a>). It installed under /usr/include and /usr/lib.<u></u><u></u></span></p>

<p>> 2. I just created a new development environment (Fedora 22) using the latest laszip from that repo. I saw you had you had the commit to remove LASzipper and LASunzipper. It appears some of the tests still reference these as well as
the lasdump apps in PDAL. I haven’t had time to look into, but did a work around for now. Just wanted you to be aware.<u></u><u></u></p>
<p><u></u> <u></u></p>
<p>LASzip needs to be pinned to a release version for now. Martin wanted to remove LASzipper/LASunzipper and use his "DLL" interface. We're starting on LAZ 1.4, and I want to get things in place for PDAL to support all of it once that's
ready. I started doing interface stuff based on his new DLL thingy, but PDAL/libLAS aren't yet caught up to it. PDAL's docker image is pinned to e7065cbc5bdbbe0c6e50c9d93d1cd346e9be6778 which should be perfectly good going forward until PDAL catches up to
LASzip.<u></u><u></u></p>
