[Boost-users] boost::function, boost::bind question

Hello,

I am using Numerical Recipes routines and I am trying to call this function

void mrqmin(Vec_I_DP &x, Vec_I_DP &y, Vec_I_DP &sig, Vec_IO_DP &a,
     Vec_I_BOOL &ia, Mat_O_DP &covar, Mat_O_DP &alpha, DP &chisq,
     void funcs(const DP, Vec_I_DP &, DP &, Vec_O_DP &), DP &alamda);

and I would like to call it with funcs being a member function pointer 
of one of my class.  I can declare the member as static but then I 
cannot access member variable, which is the goal here. Someone suggested 
to use boost to solve the problem. His solution is here

http://www.numerical-recipes.com/forum/showthread.php?s=&threadid=526

I tried to implement this but the result is this

error: cannot convert `boost::function<void ()(double, const Vec_I_DP&, 
double&, Vec_O_DP&), std::allocator<void> >' to `void (*)(DP, const 
Vec_I_DP&, DP&, Vec_O_DP&)' for argument `9' to `void NR::mrqmin(const 
Vec_I_DP&, const Vec_I_DP&, const Vec_I_DP&, Vec_IO_DP&, const 
Vec_I_BOOL&, Mat_O_DP&, Mat_O_DP&, DP&, void (*)(DP, const Vec_I_DP&, 
DP&, Vec_O_DP&), DP&)'

Any idea how I could do that?

Thanks
