Hi Roman Thank you very much! I tried to do that previously but without success using the following statement boost::lambda::bind< double >( pow, tmp - h - g , 3.15 ) but reading the documentation I realized that it is something that can be applied only to functors. Using casting works fine. Thank you very much CS On Mon, Nov 30, 2009 at 12:00 PM, Roman Perepelitsa < roman.perepelitsa@gmail.com> wrote:
could not deduce template argument for 'overloaded function type' from 'overloaded function type'
That's because function pow is overloaded. You should either explicitly cast it (replace pow with static_cast<double (*)(double>(pow)) or create a polymorphic function object that calls pow.

The problem is that It does't compile. I used MSVC++ Express. The error in the attached file is generated only by that code.

Hi All
I tried to use pow function from <cmath> in a lamda function using boost::lamdba. Below the piece of code I used. Do you know what is wrong with it? Thank you very much. CS
double l_tmp; double p_tmp;
constant_type<double>::type h( constant(2.3) ); constant_type<double>::type g( constant(1.2) );
var_type<double>::type tmp( var(l_tmp) ); var_type<double>::type pow_tmp( var(p_tmp) );
std::for_each( x.begin(), x.end(),( tmp = 10, pow_tmp = boost::lambda::bind( pow, tmp - h - g , 3.15 ) ));
Does it compile? If not, can you post an error message? If it compiles, do you encounter any problems in run time?
