I tried the same code with the CVS version and it compiled fine.

I'm using MSVC 7.1 and am getting masses of compile errors with the following code (see end of message for the errors):

#include #include <vector> #include <functional> #include

int main( void ) {

std::vector<double> vect1(3); std::vector<double> vect2(3);

// boost::zip_iterator< // boost::tuples::tuple< // std::vector<double>::const_iterator, // std::vector<double>::const_iterator // > // > // zip_it_begin( // boost::make_tuple( // vect1.begin(), // vect2.begin() // ) // );

std::vector > vect_of_tuples(3);

std::copy( boost::make_zip_iterator( boost::make_tuple( vect1.begin(), vect2.begin() ) ), boost::make_zip_iterator( boost::make_tuple( vect1.end(), vect2.end() ) ), vect_of_tuples.begin() );

return 0; }

If I uncomment the earlier instantiation of zip_it_begin then it compiles without any errors! I'm guessing this is some kind of compiler bug but and am wondering what the correct/most elegant workaround is?

Well, I don't know, but if you haven't already done so you might try the latest Boost CVS instead of 1.32. If the problem disappears that would be the easiest solution.

Do I have make sure I manually declare a zip_iterator somewhere before using make_zip_iterator?

Can't tell ya. I do note that the one you declared is using constant iterators while the one you're building with make_zip_iterator is using mutable iterators. Sorry I'm not more clue-ful here.
