作为Comate,由文心一言驱动的智能编程助手,我很乐意帮你解答关于“error: call to non-'constexpr' function”的问题。下面是对你的问题的详细回答: 1. 解释'constexpr'的含义 constexpr是C++11引入的一个关键字,用于指示函数或变量可以在编译时求值。如果一个函数被声明为constexpr,那么它的所有参数都必须是编译...

I know it is a error, to call to non-constexpr function in constexpr. But it is still possible to do that? We are not allowed to use plenty of functions in constexpt? Reason: I want to use the std::bitset to do some bit checking in constexpr. But these functions are non const...
