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...
‘constexpr’ function ‘scalar_t c10::div_floor_integer(scalar_t, scalar_t) [with scalar_t = long int]’ 96 | static constexpr int64_t int_array_3[] = {2L, c10::div_floor_integer(s0, (c10::div_floor_integer(s0, 2L))), 1L}; | ~~~^~~~ In file included from /tmp/tmp...
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...
struct Base { int i; constexpr Base(int i) : i(i) {} }; struct NonConstexpr { NonConstexpr() {} }; struct Derived : Base { using Base::Base; NonConstexpr m; }; int main() { Derived d{123}; return 0; }...
When capturing a function parameter in a lambda which is a string literal, the resulting lambda is not a constant expression as expected. However, if the capture has an initialiser, it compiles as expected: template <typename Capture> constex...

一个简单的方法是取Ts包中的每个var,创建一个std::tuple<const char*, int T::*>,然后tuple_cat将这些2-tuples组合在一起,您可以apply将其应用于您的unknown函数: // static constexpr auto value = unknown(Ts.name, Ts.offset ...); static constexpr auto value = std::apply( ...

In /O2 if I change the Width declaration tostatic constexpr auto Width = 16u;aka spefiying unsigned I don’t get garbage anymore. Also I also found that that code should not compile. This initialization,auto frameRowPrev = FrameRowView<PixelRGBui8> { Width };, should not ...
