Just tried to run a mididing [sic?] with Boost 1.60. Using the latest git of mididings. Got this: TypeError: No to_python (by-value) converter found for C++ type: boost::shared_ptr<mididings::backend::BackendBase> I found many similar reports with other tools, all referencing Boost 1.60, all talking about reverts to Boost 1.5* as the solution. Anyone have other ideas? I'd rather not revert Boost if I don't have to do so. -- *Jonathan E.
