针对你遇到的编译错误 error: unable to find string literal operator,我们可以从以下几个方面进行分析和解答: 1. 确认报错信息上下文 这个错误通常出现在C++11或更高版本的编译器中,特别是当尝试将字符串字面量与变量名直接连接时。C++11引入了一些新特性,包括自定义字符串字面量操作符,这改变了字符串字面量与变量名连接
编译出错 --- unable to find string literal operator 'operator""fmt' with 'const char [15]', #define show_log(tag, fmt, arg...) printf("[%s][%s:%d]: "fmt"\n", tag, __func__, __LINE__, ##arg) C可以编译通过,而C++编译出标题错误。 说是C++11要求,当字符串跟变量连接的时候,...
error: unabletofindstringliteraloperator'operator""x' 网上搜了一下,说是C++11要求,当字符串跟变量连接的时候,必须增加一个空格才行。因此简单修改如下即可。 #if__cplusplus < 201103L#defineLOG_INFORMATION(x, ...) LOG_ME("%s:%d, "x, __FUNCTION__,__LINE__, ##__VA_ARGS__)#else#defineLOG...
