在Code :: Blocks中启用`-std = c ++ 14`标志 [英] Enabling `-std=c++14` flag in Code::Blocks

问题描述

我已经为Windows安装了Code :: Blocks，并希望编译C ++ 14代码，比如通用lambdas，但是我已经从codeblocks.org 不支持标志
-std = c ++ 14 。

如何更新编译器并启用Code :: Blocks的 -std = c ++ 14 标志？

解决方案

要在Code :: Blocks中使用C ++ 14编译源代码，首先需要下载并安装一个支持

li>从此处（特定版本）或下载MinGW从官方网站更改为选择选项

1. 将其解压缩为例如：C：\（result将为C：\MinGW）


2. 打开Code :: Blocks


3. 前往[设定] => [编译器]。


4. 前往[工具链执行档]。


5. 将目录更改为解压缩编译器的目录。例如C：\ MinGW。


6. 更改Program Files下的所有必要文件以匹配C：\MinGW\bin下的文件：

8. 在您点击确定之前，请转到最左侧的选项卡编译器设置。


9. 选择编译器标志。


10. 为了简单起见，右键单击列表中的新标志：

b $ b

11. 输入以下内容并点击确定，然后点击您刚刚创建的标记框：

< ol start =12>

最后，需要指定调试器路径。转到设置=>调试器，单击左侧的Defualt，然后输入可执行文件的新完整路径：

现在，尝试编译一个有C ++ 14特性的程序：

  #include< iostream> 
 #include< string> 
 using namespace std; 
 
 auto main（） - > int 
 {
 auto add_two（[]（auto x，auto y）{return x + y;}）; 
 
 cout<< add_two（Is，ts）<< 工作！ << endl; 
} 
  

I have installed Code::Blocks for Windows and want to compile C++14 code like generic lambdas but the binary version of Code::Blocks that I've installed from codeblocks.org doesn't support the flag
-std=c++14.

How do I update the compiler and enable -std=c++14 flag for Code::Blocks?

解决方案

To compile your source code using C++14 in Code::Blocks, you first of all need to download and install a compiler that supports C++14 features.

Here’s how you can do it on Windows:

1. Download MinGW from here (particular build) or from official site to choose options
2. Extract it to for example: C:\ (result will be C:\MinGW)
3. Open Code::Blocks
4. Go to Settings => Compiler.
5. Go to "Toolchain Executables".
6. In the top field "Compiler’s installation directory", change the directory to the one where you extracted the compiler. E.g C:\MinGW.
7. Change all the necessary files under "Program Files" to match the files under C:\MinGW\bin:

8. Before you hit "OK", go to the leftmost tab "Compiler settings".
9. Select "Compiler Flags".
10. For simplicity, right click in the list somewhere and select "New Flag":

11. Type in the following and click "OK", and tic the box of the flag you just created:

12. Lastly, you need to specify the debugger path. Go to "Settings" => "Debugger", click "Defualt" on left hand side and enter the new full path of the executable:

Now, try to compile a program with C++14 features:

#include <iostream>
#include <string>
using namespace std;

auto main() -> int
{
    auto add_two([](auto x, auto y){ return x + y; });

    cout << add_two("I"s, "t"s) << " works!" << endl;
}
