C++ Log4cxx<&书信电报；操作员导致访问冲突

我在VS2008中有一个dll项目，它导致我的应用程序抛出访问冲突。我调试并发现在Log4cxx行中，

Log4cxx\u DEBUG（logger，myMessagestd已经为double加载了一个重载，你不能再引入另一个。你能做的就是在一个类中重载它。
好的。这是一项艰巨的任务！！但是我成功地用VS2008重新构建了Log4cxx二进制文件，现在我可以在不做任何更改的情况下运行代码了。谢谢！
namespace log4cxx { namespace helpers {
    ostream& operator<<(ostream& os, const double& a);
} }

more than one operator "<<" matches these operands:
            function "log4cxx::helpers::operator<<(std::ostream &os, const double &a)"
            function "std::basic_ostream<_Elem, _Traits>::operator<<(double _Val) [with _Elem=char, _Traits=std::char_traits<char>]"
            operand types are: std::basic_ostream<char, std::char_traits<char>> << const double

namespace std {
   ostream& operator<<(ostream& os, const double& a);
