    <p>Hi,</p>
    <p>I'm testing newer versions of boost than 1.70 currently
      distributed with CCTBX. I can't remember if I have to do something
      special other than unpacking the zip file, say boost_1_74_0.zip,
      that I download from boost.org and put it into the modules
      directory for my cctbx build. But I get several errors during
      build like:</p>
    <p><font size="-1" face="Courier New, Courier, monospace">C:\Users\Oeffner\OeffnerStuff\Work\PhenixVoyager\modules\boost\libs\filesystem\src\codecvt_error_category.cpp(71):
        error C2491: 'boost::filesystem::codecvt_error_category':
        definition of dllimport function not allowed</font><br>
    </p>
    <p>I'm have tried with the VS2015, VS2017 and the VS2019 compiler
      and they all complain. So I'm wondering if there are some other
      magic invocations that have to be done before building with a new
      version of boost.</p>
    <p>Thanks in advance for any suggestions,<br>
    </p>
    <p>Rob<br>
