The best suggestion I have is to wipe out /opt/local and reinstall macports from scratch (in case you have upgraded your OSX, this is a required step: <a href="https://trac.macports.org/wiki/Migration" class="">https://trac.macports.org/wiki/Migration</a>).</div><div class=""><br class=""></div><div class="">I would not recommend installing cryptopp manually. At the very least, you have to remove the one installed from macports/homebrew.</div><div class=""><br class=""></div><div class="">(Quick thing that may help, if you have /opt/local/lib/libcryptopp.so file, remove it. It may or may not help with the compilation.)</div><div class=""><br class=""></div><div class="">As Junxiao suggested, more information about the error is in build/config.log.</div><div class=""><br class=""></div><div class="">--</div><div class="">Alex</div><br class=""><div><blockquote type="cite" class=""><div class="">On Jul 12, 2016, at 4:17 AM, Cheryl Jose <<a href="mailto:cheryl.jose@gmail.com" class="">cheryl.jose@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class="">Hi,<div class=""><br class=""></div><div class="">I tried doing ./waf distclean and then configured for ./waf but this is the error that is showing up :</div><div class=""><br class=""></div><div class=""><p class=""><span class=""><b class="">CryptoPP is present, but is not usable</b></span></p><p class="">I have tried <b class="">CryptoPP</b> downloading it manually and then running it.
