Vscode Configuring C + +

Every time you change a computer to write C + +, it is necessary to find the configuration, is cumbersome. This time I write a blog, record the relevant configuration process.

Installing the compiler

Open the following Web site http://www.msys2.org/ , download the 64-bit MYSYS2 , and follow the steps on the home page to install the software. After complete, go to the /etc/pacman.d directory to modify the following 3 files respectively.

1. The contents of the Mirrorlist.mingw32 file are:
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/i686/

2. The contents of the Mirrorlist.mingw64 file are:
   Server = http://mirrors.ustc.edu.cn/msys2/mingw/x86_64/

3. The contents of the Mirrorlist.msys file are:
   Server = http://mirrors.ustc.edu.cn/msys2/msys/$arch/

Then enter the following command to update the system.

cd ~pacman -Syu

Enter the command again to install the C + + tool.

pacman -S mingw-w64-x86_64-toolchain

The following prompt appears, selecting 3,9,13. The file is a bit large and patiently waiting to be downloaded.

When completed, e:\Softwares\msys64\mingw64\bin\ add to the system environment. Note: The e:\Softwares catalogue is tuned according to the actual situation.

Installing Vscode

This tool we choose Vscode, convenient and practical, although the C + + plug-in weak point, but Microsoft development, will not be poor to where to go. Select the plugin after installation is complete c/c++ . See.

Open the software, then in the File menu, click Add Folder to Workspace... , select a directory as a folder to write C + + code later, here we assume that the selected folder is cpp . Create a new directory under CPP, .vscode and then create a new folder under the .vscode directory, task.json c_cpp_properties.json launch.json 3 files. See.

tasks.cppThe contents are as follows:

c_cpp_properties.jsonThe content of:

launch.jsonFor code debugging, it does not work at this time.

Run code

After completing the above work, in the CPP directory, write a test.cpp file, and then press Ctrl+Shift+B , will generate the Test.exe file. The test.exe is then executed at the terminal.
