<div dir="ltr">I'm not sure about Brad's experience with this, but I think my note to the last person who had a problem with this was incorrect. I don't think boost needs to be rebuilt. Instead, I think you need to make sure that PCL is built with C++11. The problem comes when PCL is built with C++03 and PDAL is built with C++11. The lanczos initializer is in a header, and if it's built consistently with your libraries, all should be well, I think.<div><br></div><div>Brad?</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Jan 8, 2015 at 3:30 PM, Matthew Hanson <span dir="ltr"><<a href="mailto:mhanson@appliedgeosolutions.com" target="_blank">mhanson@appliedgeosolutions.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Unless someone has a better idea, I'm going to go ahead and try to compile boost with c++11 support, as I've just been installing from the Ubuntu repo and I'm not sure the compile flags used.</div><div class="HOEnZb"><div class="h5"><div class="gmail_extra"><br clear="all"><div><div><div dir="ltr">Matthew Hanson<div>Applied GeoSolutions</div><div><a href="tel:%28603%29%20659-3363%20x91" value="+16036593363" target="_blank">(603) 659-3363 x91</a></div><div><a href="http://appliedgeosolutions.com" target="_blank">http://appliedgeosolutions.com</a></div><div><a href="mailto:mhanson@appliedgeosolutions.com" target="_blank">mhanson@appliedgeosolutions.com</a></div><div><br></div></div></div></div>
