I'm evaluating using exprtk to evaluate string expressions (e.g., "a"+"b") an, as such, I've tried to create a std::string parser (exprtk::parser).
This throws out a bunch of errors in compilation about multiple overloaded methods that instantiate to the same signature (parser::operator() and parser::get_variable()).
I haven't found anything in the documentation to do this although it says it handles string types.
How would I be able to do this?
