Hi,
I am trying to compile a package that utilizes boost libraries, and the compilation fails. This is on OS X El Capitan, with clang version: 7.3.0.7030029. Is this a known issue, and is there a work around?
In file included from /opt/local/include/boost/signals2/slot_base.hpp:18:
/opt/local/include/boost/signals2/detail/foreign_ptr.hpp:42:54: error: reference to 'weak_ptr' is ambiguous
