[Boost-users] bind trouble

Hello everybody!

I ran into a very weird problem with boost::bind and boost::function. I
am using boost 1.33.1 with a g++ 4.0.3 on a Ubuntu dapper system. The
code which does not compile is:

boost::function< double(double) > pFunc = boost::bind(std::pow, _1, -3);

While this code fragment does:

double f(double k, double p) {
  return std::pow(double(k), p);
}

boost::function< double(std::size_t) > pFunc = boost::bind(f, _1, -3);

Ok, I got a solution, but may someone enlighten me what is wrong with
the first version? The error message from g++ is

correlFunc.cpp: In function 'int main(int, char**)':
correlFunc.cpp:184: error: no matching function for call to
'bind(<unknown type>, boost::arg<1>&, double)'

Thanks in advance!

Greetings,
