I use Dev-C++,and the snipet of the program is:

#pragma hdrstop

# include <iostream>
# include <vector>
# include <iterator>
# include "boost/math/common_factor.hpp"
# include "boost/lambda/lambda.hpp"
# include "boost/lambda/bind.hpp"
# include "boost/lambda/if.hpp"
# include "boost/lambda/casts.hpp"
# include "boost/lambda/construct.hpp"
# include "boost/lambda/loops.hpp"
# include "boost/lambda/switch.hpp"
# include "boost/tuple/tuple.hpp"
# include "boost/tuple/tuple_comparison.hpp"
# include <string>
# include <map>

 

using namespace std;
using namespace boost::lambda;
using namespace boost;

void a(){
    std::cout<<std::pow(4,3);  
    return;
}  
...............

but the complier told me that:

main2test.cpp: In function `void a()':
main2test.cpp:69: call of overloaded `pow(int, int)' is ambiguous
F:/CB2009/Dev-Cpp/include/math.h:162: candidates are: double pow(double, double)
F:/CB2009/Dev-Cpp/include/c++/cmath:401:      float std::pow(float,  float)
F:/CB2009/Dev-Cpp/include/c++/cmath:410:                 long double
   std::pow(long double, long double)

F:/CB2009/Dev-Cpp/include/c++/cmath:419:                 double
   std::pow(double, int)

F:/CB2009/Dev-Cpp/include/c++/cmath:423:                 float std::pow(float,
   int)
F:/CB2009/Dev-Cpp/include/c++/cmath:427:                 long double
   std::pow(long double, int)

 

And in my computer, the C++ libraries includes are

F:\CB2009\Dev-Cpp\include\c++

F:\CB2009\Dev-Cpp\include\c++\mingw32

F:\CB2009\Dev-Cpp\include\c++\backward

F:\CB2009\Dev-Cpp\include

F:\CB2009\boost_1_34_1\boost_1_34_1

I do not know how to solve it.I do not use <math> or <cmath> yet.

Why the complier told me such files? And whether the two files are included in other files or not?

And can I use:

bind(&std::pow,constant(-1),bind(&IIPrimemap::size,var(primemapvec)));

in the program? where :

typedef std::pair<int, int> IIPrimepair;
std::vector<IIPrimepair> primepairvec;

 

Can anyone with kindness help me?
