== Compilation system requirements ==
The Linux SDK, '''orangepi-build''', only supports running on X64 computers with '''<span style="color:#FF0000">Ubuntu 22.04</span>''' installed, so before downloading orangepi-build, please make sure that the Ubuntu version installed on your computer is Ubuntu 22.04. The command to check the Ubuntu version installed on the computer is as follows. If the Release field does not display '''<span style="color:#FF0000">22.04</span>''', it means that the current Ubuntu version does not meet the requirements. Please replace the system before performing the following operations.

If the computer is installed with a Windows system and there is no computer with Ubuntu 22.04 installed, you can consider using '''VirtualBox''' or '''VMware''' to install an Ubuntu 22.04 virtual machine in the Windows system. But please note, do not compile orangepi-build on the WSL virtual machine, because orangepi-build has not been tested in the WSL virtual machine, so it cannot be guaranteed that orangepi-build can be used normally in WSL, and please do not compile it on the Linux system of the development board Use orangepi-build in. The download address of the installation image of Ubuntu 22.04 '''<span style="color:#FF0000">amd64</span>''' version is:
After installing Ubuntu 22.04 on the computer or virtual machine, please set the software source of Ubuntu 22.04 to Tsinghua source (or other domestic sources that you think is fast), otherwise it is easy to make mistakes due to network reasons when installing software later. The steps to replace Tsinghua source are as follows:
