添加快捷方式

爲了打開Clion方便，不需./clion.sh然後打開

新建圖標

cd /usr/share/applications/
sudo touch clion.desktop
sudo gedit clion.desktop

然後直接輸入(地址一般不同，這個需要更改的)：

[Desktop Entry]
Encoding=UTF-8

Name=CLion

Comment=clion-2019.2

Exec=/home/pc314/clion-2019.2/bin/clion.sh

Icon=/home/pc314/clion-2019.2/bin/clion.svg

Categories=Application;Development;Java;IDE

Version=2019.2

Type=Application

#Terminal=1

最後可以在search中搜索Clion就可以看到圖標了。右鍵點擊圖標，會出現它的信息，在launch將會更方便。

新建一個Ｃ＋＋代碼

CLion 採用 CMake 項目模型，任何基於 CMake 的項目都無需額外配置即可在 CLion 中輕鬆的打開：只需指向一個頂層的 CMakeLists.txt 文件以打開項目。

我們看一下CMakeLists.txt文件，裏面中的project(untitled)表示一個Cmake文件，add_executable(untitled main.cpp)表示一個c++ source file。

cmake_minimum_required(VERSION 3.14)
project(untitled)

set(CMAKE_CXX_STANDARD 14)

add_executable(untitled main.cpp)

假設在項目untitled下新建一個C++ source file,命名爲１.cpp文件，那麼CMakeLists.txt就需要修改爲

cmake_minimum_required(VERSION 3.14)
project(untitled)

set(CMAKE_CXX_STANDARD 14)

add_executable(untitled 1.cpp)

這樣子就可以運行了，測試代碼

#include <iostream>

int main() {
    std::cout << "Hello, World!" << std::endl;
    return 0;
}
