我试着让自己进入C++,并购买了Bjarne Stroustrup的《编程-使用C++的原理和实践》一书。
当我试图获取编译以下源代码:
#include "std_lib_facilities.h"
int main(){
cout<<"Hello, World!\n";
keep_window_open();
return 0;
}
字符串
我得到以下编译错误:

我得到它,我的编译器是不使用C++11功能,但我不知道我如何可以更新编译器.我应该让知道,我使用的是MacOSX(10.10约塞米蒂),并试图编译与xCode和textmate.我甚至试图按照本教程(https://wiki.helsinki.fi/display/HUGG/Installing+the+GNU+compilers+on+Mac+OS+X),但它没有帮助.(至少当我试图编译与文本伴侣)
希望你能帮到我:)

如果你在Mac或Linux上,编译器通常是g或clang;要访问C11,只需在调用编译器时指定
-std=c++11
作为选项(假设你有最新版本)。e37o9pze2#
你需要做的是打开项目设置->构建设置,将 C++ 方言设置为C11,将C标准库设置为libc++(LLVM C标准库支持C11)。

从构建设置中,将** C++ 方言**调整为C++11..

另外,请确保您使用的是LLVM C库,因为它完全支持C 11。

并在其中添加-std=c++11
