Kylin operating system (kylinos) from entry to proficient - R & D environment - Chapter 21 C++/C language development environment construction

0. Basic environment

Category: Notebook Model: Great Wall of China NF14C
Hardware platform: Feiteng processor (ArmV8 instruction set)
System: Galaxy Kirin OS V10 SP1 (2203)

Key words:
Xinchuang, Kylin system, linux, c++, c, kernel Feiteng, arm

1. Demand background

For low-level and high-performance computing, C/C++ has irreplaceable performance advantages and the ability to fully control hardware. Therefore, although the GO language and Java language are now popular, the research and development of C and C++ is still indispensable, especially such as artificial intelligence algorithm packages.

2. Basic preparations

2.1 JDK installation

JDK installation is because Clion and Eclipse are used, open the terminal and enter

 sudo apt-get install openjdk-11-jdk -y

2.2 C++ compilation dependency installation

 sudo apt-get install llvm gcc g++ cmake git vim -y

3. Use clion for C++/C language development (personal preference, used to jetbrains series)

Open https://www.jetbrains.com.cn/en-us/clion/download/other.html ,

Download the binary version corresponding to Clion according to your needs, https://download.jetbrains.com.cn/cpp/CLion-2022.1.3.tar.gz?_gl=1 14g9b34 _ga MTA0NTY4MjM1Ny4xNjU2MjUyODcw _ga_9J976DJZ68*MTY1NjI1Mjg2OS4xLjAuMTY1NjI1Mjg4
Unzip to the corresponding folder, the folder path cannot contain Chinese.

Then use the latest activation code obtained on the website to activate

Activation successful, exit

4. Use eclipse for c++/C language development

Eclipse can be downloaded through the application market (you can also download the aarch version of the installer through the official website, and select it directly in it)

After startup, click the help menu to enter the plugin market

Search for the C++ integrated environment plug-in CDT, click to install (or download the latest plug-in directly from the official website https://www.eclipse.org/cdt/downloads.php )

After the installation is complete, restart to take effect.

5. Use Qt Creator for C++/C language development

Qt creator can be downloaded and installed through the application market

Install qmake under the application market (you have to enter all to see it)

The effect after opening

In addition, you need to install the qt sdk
https://download.qt.io/archive/qt

https://download.qt.io/archive/qt/6.3/6.3.1/single/

Unzip to a custom folder to open qt creator, click Tools | Options menu

My qmake location is as follows (cmake does not need to be configured, it has been automatically detected)

The kits are configured

6. Examples

6.1 Eclipse

Open eclipse, click New Project, find C++, as shown below.

6.2 Clion and configuration

The built-in cmake cannot work under arm Feiteng, you need to configure toolchains in the setting.

After configuration, the effect is as follows

Save, the IDE will rebuild the project index, please wait patiently. The effect of compilation and operation is as follows

6.3 qt creator (not perfect, I haven't engaged in QT for a long time, welcome QT developers to comment and add)
