First use a computer with an interface to find the link on the official website
https://www.intel.com/content/www/us/en/developer/articles/tool/oneapi-standalone-components.html#dpcpp-cpp
Directly in one step, copy the second link
Back to the terminal to download
wget https://registrationcenter-download.intel.com/akdlm/IRC_NAS/89283df8-c667-47b0-b7e1-c4573e37bd3e/l_dpcpp-cpp-compiler_p_2023.1.0.46347_offline.sh
run.sh
At this time, the current folder should have this file, add permissions, run
chmod +x l_dpcpp-cpp-compiler_p_2023.1.0.46347_offline.sh
sudo ./l_dpcpp-cpp-compiler_p_2023.1.0.46347_offline.sh
Install
The following interface appears
Accept, there will be an installation of eclipse in the middle, you can skip it, all the way to next
After loading, display the installation directory,
enter the installation path, and configure it
source setvars.sh intel64
that's it
run the program
Similar to c++ compilation
An official example (be careful not to create a new test file in the installation path just now)

warn
You may have noticed a warning when compiling above, indicating that the dpcpp command option you are currently using is deprecated and will be removed in a future release. It is recommended to use the icpx -fsycl command option instead, so it is best to compile like this:
