error: ‘numeric_limits’ is not a member of ‘std’ 解决方案: 在报错文件中增加 #include <limits> 即可 2. reinterpret_cast<iconv_t>(-1) 报错 invalid cast from type ‘int’ to type ‘iconv_t’ 解决方案: 将 reinterpret_cast<iconv_t>(-1) 替换为 (iconv_t)(-1) , 编译器提示 iconv...
staticinline qint64 nullJd() {returnstd::numeric_limits<qint64>::min(); } 报错: 2、将原来的代码改成 staticinline qint64 nullJd() {return(std::numeric_limits<qint64>::min)(); } ZC: 注意括号的位置 3、
