1.Compiler Environment
It is recommended to use Ubuntu 22.04 system or above. If you encounter an error during
compilation, you can check the error message and install the corresponding software packages
accordingly. Other Ubuntu versions may need to adjust the software package accordingly. In addition
to the system requirements, there are other hardware and software requirements.
Hardware requirements
Software requirements
64-bit system, hard disk space should be greater than 40G. If you do
multiple builds, you will need more hard drive space.
