Looking at the README file from 
<https://sourceforge.net/p/htmlcxx/code/ci/master/tree/>,
it looks to me that upstream has moved to <https://github.com/bonitao/htmlcxx>. 
(judging by the name of the repo owner)
Can you try asking upstream for a new release? The last commit 
(<https://github.com/bonitao/htmlcxx/commit/0ffa3e90b7dc3944f199fd80ab47c2a82589209a>)
has the message 'Fix c+11 compilation'.


Cheers,
Bruno
