Hi, I installed Boost 1.58.0 today, having been using 1.57.0 previously, and noticed that a part of my code that uses boost::factory doesn't compile anymore. Here's briefly what I'm doing, followed by the error message I'm getting: typedef boost::function<Apollo::ReportGenerator*(Apollo::ApolloBaseModel*)> reportFactory; struct reportListing { std::string displayName; reportFactory factory; reportListing(std::string name, reportFactory f) : displayName(name), factory(f) { } }; std::vector<reportListing> reportFactories; reportFactories.push_back(reportListing("Scenario Analyzer", boost::factory<Apollo::ScenarioAnalyzer*>())); // Apollo::ReportGenerator being the base class from which Apollo::ScenarioAnalyzer is derived ... The constructor for ScenarioAnalyzer is: ScenarioAnalyzer(Apollo::ApolloBaseModel* model) This fails to compile with the following error (on Windows 7 using Visual C++ 12): error C2664: 'Apollo::ScenarioAnalyzer *boost::factory<Pointer,void,factory_alloc_for_pointee_and_deleter>::operator ()(void) const' : cannot convert argument 1 from 'Apollo::ApolloBaseModel *' to 'Apollo::ApolloBaseModel *&' I'm just wondering if that is caused by an intentional change or not, because according to the change log to boost::factory no significant changes with implications to backward compatibility have been made. Also, I'm not sure I know how to get rid of this error. Thanks for the help! /Fadi ________________________________ Fadi Bitar Modeling and simulation specialist Energy Markets Telephone direct +46 (0)8 695 64 05 Mobile +46 725 40 64 05 fadi.bitar@sweco.se<mailto:fadi.bitar@sweco.se> Sweco Energuide AB Gjörwellsgatan 22 P.O.
