It is a known issue (i.e., the fact that ndn-cxx needs to be included before any other boost library header), but could be a little bit tricky to debug. We will try to make an FAQ question for that soon. Unfortunately, this requirement is a necessary evil to make applications seamlessly work with boost and c++11 routines.</div><div class=""><br class=""></div><div class="">—</div><div class="">Alex</div><br class=""><div><blockquote type="cite" class=""><div class="">On May 1, 2015, at 8:22 AM, Anil Jangam <<a href="mailto:anilj.mailing@gmail.com" class="">anilj.mailing@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">I figured out that this was the problem.<div class=""><br class=""></div><div class="">// boost needs to be included after ndn-cxx, otherwise there will be conflict with _1, _2, ...<br class=""></div><div class=""><br class=""></div><div class="">/anil.</div></div><div class="gmail_extra"><br class=""><div class="gmail_quote">On Thu, Apr 30, 2015 at 3:20 PM, Anil Jangam <span dir="ltr" class=""><<a href="mailto:anilj.mailing@gmail.com" target="_blank" class="">anilj.mailing@gmail.com</a>></span> wrote:<br class=""><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class=""><div class="gmail_quote">Can someone comment why this error coming?<div class=""><div class="h5"><br class=""><br class=""><br class=""><div dir="ltr" class="">This error is coming from all these lines..
