Re: [Boost-users] boost 1.47: gcc file dependency generation trips over BOOST_PARAMETER_MAX_ARITY

Thank you for your answer. I believe we are not on the same page. Obviously, when I define the max arity to a value of 7 or more, the preprocessor will finish properly. But the point I am trying to make is more subtle, namely, that the generation of the project dependencies has not a thing to do with the boost max arity. Therefore, the definition of that macro would be terribly misplaced in the make rule for the dependencies, which has only to do with the dependent files and nothing with the numeric values of macros. At least, that is how it should be in my opinion. I don't know what the boost max arity means or what its for, but it seems to me that it is a run time variable. As such, it should be handled by the code and not by preprocessor directives, surely not with this side-effect. I hope this can be acknowledged. Kind regards, Ytsen. 2011/9/15 Ivan Le Lann :

Thank you for your response, please allow me to explain the problem a bit clearer:

(removed -MM explanation)

I believe this has nothing to do with -MM. Does your code compile without dependency generation ?

Obviously Boost.Signals2 needs this macro to be at least 7. You probably include another boost library before Signals2 that default it to less than 7.

See: http://boost.2283326.n4.nabble.com/Accumulators-Signals2-Compilation-error-w... I think you should define this macro (to 7 or more) in your compiler command.
