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...

系统:Win10 环境:VS2019+QT5.9.3 +vs2015编译器 Qt App项目,在使用Qwt时什么都没做,默认项目直接报这种错误. 解决: 1 先在网上搜索了一下,发现有vs2017中遇到,说是qalgorithms.h的问题,尝试了无效 2 检查项目参数,由于项目是vs自动生成,因此
