Enter the following commands:

source /opt/intel/oneapi/2025.0/oneapi-vars.sh
export CC=icx
export CXX=icpx
./meson.py build

Generate the following output：

The Meson build system
Version: 0.61.1
Source dir: /home/username/SU2

meson.build:1:0: ERROR: Unknown compiler(s): [['icx']]


Has anyone successfully compiled under oneAPI 2025? How to operate? Thanks!

Maybe pojnt to the exact location? Could be that meson could not find it.
$ which icx
/usr/bin/icx
$ export CC = /usr/bin/icx

Thank you.
After checking, the environment variables have been correctly set. I suspect that meson does not recognize Intel's new compiler
