Unable to run/detect device due to missing environment variables.

Jump to solution

OS

Windows 10

IDE

Visual Studio 19

Compiler

Any compiler (tested with msvc, clang, or Intel(R) oneAPI DPC++ compiler)

Toolkit

oneAPI Base Toolkit version 2021.1-beta09

Problem

After building .exe or .dll that relies one oneAPI DPC++, execute the .exe or .dll without going through Visual Studio "Intel(R) oneAPI DPC++ Compiler" platform toolset, (e.g., cmd).

After taking a look, the said toolset adds these few lines to the debugging environment.

OCL_ICD_FILENAMES=C:\Program Files (x86)\Intel\oneAPI\compiler\2021.1-beta09\windows\..\windows\lib\emu\intelocl64_emu.dll;C:\Program Files (x86)\Intel\oneAPI\compiler\2021.1-beta09\windows\..\windows\lib\x64\intelocl64.dll;

The program will not run properly without those environment variables, either cannot find dll, cannot detect OpenCL devices, or some native error, etc.

Shouldn't this be done by the installer?

Hi,

We can see that from screenshots you have provided, you are able to successfully initialize oneAI environment.

Could you please try running your application executable after initializing the oneAPI environment and let us know if you face any errors?

Example:

We have tried running the vector-add-usm code which is available as part of oneAPI samples.

After building the vector-add-usm solution. Try running the executable inside <visualstudio/repos/projectname/x64/Debug/>vector-add-usm.exe

Regarding "sys_check.bat errors": We will get back to you after discussing it with the concerned internal team.

 

Thanks & Regards

Hi,

You need to set up the oneAPI environment in the command prompt before running any oneAPI application.

  1. Please run the setvars.bat (located at oneAPI Installed directory) in cmd prompt to initialize the oneAPI environment.
  2. Run the application .exe file after initializing the oneAPI environment.

Please let us know if you face any further challenges.


Thanks & Regards

It seems DPC++ dlls directory still wasn't added to PATH.


Extended information that may help,

setvars.bat ran successfully as follows,

sys_check.bat wasn't successful,

Just to point out, I do have python installed and added to system PATH.

Hey Goutham,

It seems what you did works, screenshot for reference (also works on my own application (dll)).

However, is there any plans in the future (e.g., on a stable release) to permanently change the environment variable during installation (like setx instead of set), instead of having to run setvars.bat every time?
