Hi Phil, Since std::pow has a few different overloads (for things like long double std::complex, etc.) you're probably running into the problem described here: < http://www.boost.org/doc/libs/1_57_0/libs/bind/bind.html#err_overloaded> The solution it suggests will work in your case. Happily, phoenix makes it easy to call cmath functions by wrapping them in this file: < https://github.com/boostorg/phoenix/blob/master/include/boost/phoenix/stl/cmath.hpp> So you should be able to call pow without messing with bind.

Hello,
I try to use phoenix bind to bind std::pow for double values, but I get errors, because the template parameters not set:
phoenix::bind(&std::pow, _val, _1)
I would like to compile it with C++11. How can I setup the template parameter on the phoenix bind? At the moment I have defined a function double mypow(double a, double b) { return std::pow(a,b); } but can I do this directly with std::pow in the bind call?
Thanks a lot
Phil
