Would one of you C++ experts help me out with a polymake build failure with gcc 6? Polymake defines a Vector class in lib/core/include/Vector.h (also see lib/core/include/GenericVector.h). Unlike with gcc 5 and earlier, everywhere in the code that something like this is done: Vector<int> x = ...; Vector<int> y = ..; const Vector<int> z = x + y; where + can be one of several operators defined for the Vector class, gcc errors like this: error: invalid initialization of non-const reference of type 'pm::Vector<int>&' from an rvalue of type 'pm::Vector<int>' I assume the error refers to the temporary created by the operator. I've added -std=gnu++98 to CXXFLAGS, but that doesn't help. I guess that the Vector class is missing something needed by gcc 6, but I don't know what that something might be. Any hints are much appreciated. See http://koji.fedoraproject.org/koji/taskinfo?taskID=12969245 for an example build showing the error.
I'll take a look. -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
