我使用 ezlogger 库为我们的项目记录日志。升级 OSX Maverick 后我无法编译代码，g++ 编译器在编译日志记录宏时抛出错误。错误信息:

get_verbosity_level_tolerance() 的代码如下:
struct ezlogger_verbosity_level_policy
{
static inline verbosity get_verbosity_level_tolerance(){return set_or_get_verbosity_level_tolerance(true);}
static void set_verbosity_level_tolerance(verbosity NewValue){set_or_get_verbosity_level_tolerance(false, NewValue);}
private:
inline static verbosity initial_verbosity_level(){return log_default_verbosity_level;}
static verbosity set_or_get_verbosity_level_tolerance(bool GetLevel, verbosity NewValue = log_default_verbosity_level)
{
static verbosity verbosity_level = initial_verbosity_level();
if (!GetLevel) verbosity_level = NewValue;
return verbosity_level;
}
};
有什么想法可以解决这个问题吗？
最佳答案
get_verbosity_level_tolerance() 是结构 ezlogger_verbosity_level_policy 的成员。
尝试调用 ezlogger_verbosity_level_policy::get_verbosity_level_tolerance() 而不是只调用 get_verbosity_level_tolerance()
