[Rcpp-devel] package with module not compiling on Mac

[Robin Girard]

Merci Romain ! 

I am doing this to make possible a direct use of the result such as in A=Sum(f1.Swap(0),f2.Etoile())
This is not really necessary but sometime convenient. That's old prog souvenirs for me so please correct me if this is stupid. 

Can it be that my clone is wrong ? (indeed I am not sure to really understand how it works) 

	cplfunction* clone(){
		return new cplfunction() ;
	}

I will try to make it by adapting the two functions and their use !
Robin

Hello,

I can reproduce the compiler error on my mac. If I comment the methods 
Swap and Etoile, then I can compile the package.

Now looking at the signatures:

cplfunction & Swap(double y) ;
cplfunction & Etoile() ;

I think the problem is that they return a reference. Looking at their 
code, it looks like they only ever return *this. Why are you doing this ?

I'd suggest you return void.
