Basic Configuration Guide for Linux C/C Development Using CLion

CLion is an integrated development environment (IDE) developed by JetBrains, specifically used for the development of C and C languages. On Linux systems, CLion provides powerful code editing, debugging and building functions, making programming work more efficient and convenient. This article will describe how to basically configure CLion for Linux C/C development, along with some code examples.

Step One: Install CLion
First, download the CLion installation package for Linux systems from the JetBrains official website and install it according to the installation wizard. After the installation is complete, launch CLion.

Step 2: Create a new project
On the CLion welcome interface, click "Create New Project" to create a new project. Select "C Executable" or "C Executable" as the project type and click "Next" to continue.

Step 3: Configure the compiler
In the project settings interface, select the compiler suitable for your system. Generally, GCC is the default compiler for Linux systems, and you can choose GCC as the compiler. You can also choose another compiler if you have one installed. Click "Next" to continue.

Step 4: Configure the project path
In the project settings interface, select the path applicable to your project. You can select an existing directory or create a new directory to hold the project files. Click "Finish" to complete the creation of the project.

Step 5: Write code
In the editing interface of CLion, you can start writing C/C code. CLion provides functions such as intelligent code completion, syntax checking, and automatic formatting to make programming more efficient. The following is a simple C code example:

#include <stdio.h>

int main() {
    printf("Hello, World!
");
    return 0;
}

Step 6: Build and Run
In the CLion toolbar, there is a button called "Build". Click this button to build the project . After the build is completed, you can click the "Run" button to run the project. CLion provides debugging functions, which can debug programs by setting breakpoints and observing the values ​​of variables.

Step 7: Add external libraries
If your project needs to use external libraries, you can configure the project's dependencies in CLion. In the "Build, Execution, Deployment -> CMake -> Build" tab of the project settings interface, you can add the path and dependencies of the external library. For example, if your project uses the OpenCV library, you can add the path and link to the OpenCV library.

# CMakeLists.txt
cmake_minimum_required(VERSION 3.17)
project(MyProject)

set(CMAKE_CXX_STANDARD 14)

# 添加OpenCV库的路径和链接
set(OpenCV_DIR <path_to_opencv>)
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})

add_executable(MyProject main.cpp)
target_link_libraries(MyProject ${OpenCV_LIBS})

Summary:
Through the above steps, CLion can be basically configured for Linux C/C development. CLion provides a wealth of functions and tools to help developers improve development efficiency. At the same time, CLion also supports version control tools, such as Git, to facilitate team collaboration and project management. I hope this article can provide some help to novice developers and make it easier for them to develop Linux C/C.
