当你遇到 'nullptr' was not declared in this scope 的错误时,这通常意味着你的编译器或开发环境没有正确识别 nullptr 关键字。以下是几个可能的解决方案,我将按照你提供的提示逐一解释: 1. 确认编程环境和上下文 首先,确保你的开发环境支持C++11或更高版本,因为 nullptr 是在C++11标准中引入的。如
error: 'nullptr' was not declared in this scope 两种情况 1. vs code 自带编译失败的,没有使用code runner插件的 在task.josn 里的这行json代码里 加上 "-std=c++11" "args": ["-m32","-g","-std=c++11","${file}", "-o", "${fileDirname}/${fileBasenameNoExtension}.exe"], 2. 使用...
'nullptr' was not declared in this scope 问题是编译器没有开启C++11特性。 如果直接使用gcc/g++, 在 gcc /g++参数中添加 -std=c11 / -std=c++11 即: g++-g-Wall-std=c++11main.cpp gcc-g-Wall-std=c11main.cpp 1. 2. 3. 注意: 需要更新gcc/g++版本。 5以上应该就可以。 若在CMake中遇到该nu...
error: ‘nullptr’ was not declared in this scope 网上说增加一个编译选项: -std=c++0x 或 -std=c++11 1. 2. 3. 吾是cmake,一时也没找到选项加入。干脆使用了一个宏定义解决: #define nullptr NULL 1.
