Hi, Both the statements below bind function buildPair. While the first works the other fails. What could be a possible fix. Thanks in advance.

//---- Function to be used by bind ------------------------- template std::pair buildPair(X x, Y y) { std::pair apair(x,y); return apair; }

(std::cout<

This one does not bind buildPair, it evaluates buildPair immediately. This line of code is equivalent to (std::cout<<_1<<' ')(1,2);

(bind(buildPair,_1,_2))(3,5); ///-fails------------

You should specify template arguments for buildPair. (bind(buildPair,_1,_2))(3,5); Roman Perepelitsa.
