I've already installed DPC++/ C++ Intel® oneAPI compiler and MKL library. However, even though i set environment variables by running the command:
source /opt/intel/oneapi/setvars.sh
It appeared as below:
:: initializing oneAPI environment ...
-bash: BASH_VERSION = 5.1.16(1)-release
args: Using "$@" for setvars.sh arguments:
:: compiler -- latest
:: debugger -- latest
:: dev-utilities -- latest
:: mkl -- latest
:: tbb -- latest
:: oneAPI environment initialized ::
And the problem is, whenever i run: "cmake .. -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx", it cannot find the icx and icpx file, tough these files are still working well:
~$ icx --version
Intel(R) oneAPI DPC++/C++ Compiler 2023.2.0 (2023.2.0.20230721)
Target: x86_64-unknown-linux-gnu
Thread model: posix
InstalledDir: /opt/intel/oneapi/compiler/2023.2.1/linux/bin-llvm
Configuration file: /opt/intel/oneapi/compiler/2023.2.1/linux/bin-llvm/../bin/icx.cfg
icpx --version
Intel(R) oneAPI DPC++/C++ Compiler 2023.2.0 (2023.2.0.20230721)
Target: x86_64-unknown-linux-gnu

InstalledDir: /opt/intel/oneapi/compiler/2023.2.1/linux/bin-llvm
Configuration file: /opt/intel/oneapi/compiler/2023.2.1/linux/bin-llvm/../bin/icpx.cfg.
So everytime I run the cmake command, i have to type the directory of these files.
My second problem is when I tried to build SYCL with CMake for GROMACS, the problem came up as:
"CMake Error at cmake/gmxManageSYCL.cmake:384 (message):
Cannot compile a SYCL program with -fsycl. Try a different compiler or
disable SYCL.
Call Stack (most recent call first):
CMakeLists.txt:663 (include)"
Here is my command in Ubuntu 22.04 and the full details for what happened:

Hi,
Thank you for posting in Intel Communities.
>> And the problem is, whenever i run: "cmake .. -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx", it cannot find the icx and icpx file, tough these files are still working well:
On the Ubuntu 22.04 system, I have installed the latest Intel oneAPI DPC++/C++ Compiler, Math Kernel Library (oneMKL), and run the below command.
source /opt/intel/oneapi/setvars.sh
cmake .. -DCMAKE_C_COMPILER=icx -DCMAKE_CXX_COMPILER=icpx
We did not face any issues with icx/icpx. Please find the below screenshot for more details.

We are not able to see this error when we remove the sudo in your command. Please find the below screenshot for more details.
Could you please try building the GROMACS with CMake without using sudo and let us know the results?
Please let us know if you still face any issues.
Thanks and Regards,

Thank you very much, I finally solved the problem thanks to your help. I didn't know that using sudo can cause problems, as I did install GROMACS successfully before with sudo (but without SYCL programming) since GROMACS building folder requires root user permissions. Anyway, I really appreciate your enthusiasm.
Best regards.
