在VC6中使用boost1.33.1的lexical_cast编译不能通过的问题
#include <boost/lexical_cast.hpp>
#include <iostream>
void boost_lexical()
{
using boost::lexical_cast;
int a=10;
double b=20;
a = lexical_cast <int> ( "123 ");
b = lexical_cast <double> ( "123.12 ");
std::cout < <a < <std::endl;
std::cout < <b < <std::endl;
}
int main()
{
boost_lexical();
return 0;
}

为什么不能编译通过呢？哪位大大告诉一生？
我的环境：VC6+SP6+WINXPSP2
另：boost的包含路径已经配置好了的
[解决办法]
#include <boost/lexical_cast.hpp>
#include <iostream>
void boost_lexical()
{
using namespace boost;
int a=10;
double b=20;
a = lexical_cast <int> ( "123 ");
b = lexical_cast <double> ( "123.12 ");
std::cout < <a < <std::endl;
std::cout < <b < <std::endl;
}
int main()
{
boost_lexical();
return 0;
}
[解决办法]
写成 a = boost::lexical_cast <int> ( "123 "); 试试
[解决办法]
也有可能你库没有加对路径
[解决办法]
改为:
//using boost::lexical_cast;
int a=10;
double b=20;
a = boost::lexical_cast <int> ( "123 ");
b = boost::lexical_cast <double> ( "123.12 ");
命名空间与模板特化的问题.
