如何计算两个size_t变量的最大值

Question

我的代码中有这个.

vector<unsigned int> import;
vector<unsigned int> aquired;
. . .
size_t new_size = max(import.size(),aquired.size());

我收到此错误:

 error: more than one instance of
 overloaded function "max" matches the
 argument list:
             function "max(int, int)"
             function "max(unsigned int, unsigned int)"
             function "max(int, unsigned int)"
             function "max(unsigned int, int)"
             function "max(long long, long long)"
             function "max(unsigned long long, unsigned long long)"
             function "max(long long, unsigned long long)"
             function "max(unsigned long long, long long)"
             function "max(float, float)"
             function "max(double, double)"
             function "max(float, double)"
             function "max(double, float)"
             argument types are: (size_t, size_t)

我的理解是,这size_t是一个unsigned int.那么为什么这是一个问题,我该如何解决它.

#include <algorithm>

size_t val1;
size_t val2;

size_t maxValue = std::max<size_t>(val1, val2);
