Hi, I am trying to compile graph-tool 2.2.26 on Ubuntu 12.04 (python 2.7.3, boost 1.46, gcc 4.6.3) and hit the following error: $ ./configure --enable-openmp $ make [...] CXX graph_io.lo In file included from graph_adaptor.hh:25:0, from graph_filtering.hh:52, from graph_io.cc:35: /usr/include/boost/range/join.hpp:63:60: error: 'template<class SinglePassRange1, class SinglePassRange2> boost::joined_range<const SinglePassRange1, const SinglePassRange2> boost::join(const SinglePassRange1&, const SinglePassRange2&)' conflicts with previous using declaration 'template<class SequenceSequenceT, class Range1T> typename boost::range_value<SequenceSequenceT>::type boost::algorithm::join(const SequenceSequenceT&, const Range1T&) Any suggestions on how to fix this?
