It supports both C++11 and C++14. However, when I write a program using nullptr it is still telling me that 'nullptr' was not declared in this scope . What else do I have to do in order for nullptr to be accepted by the compiler? c++ c++11 nullptr tdm-gcc Share Follow edited M...
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...

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.
'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。
