aocl-clang exists but is not working!

I try run hello_world and get this error:

C:\Windows\system32>aocl version

aocl 16.0.0.211 (Altera SDK for OpenCL, Version 16.0.0 Build 211, Copyright (C)

C:\Windows\system32>%ALTERAOCLSDKROOT%\init_opencl.bat

AOCL_BOARD_PACKAGE_ROOT is set to C:\altera\16.0\hld\board\s5phq. Using that.

Adding C:\altera\16.0\hld\bin to PATH

Error: aoc: Executable C:/altera/16.0/hld/windows64/bin/aocl-clang exists but is

not working!

The cause of failure cannot be determined. Run executable manually and watch for

error messages.

Can anybody help me?

Since you seem to have installed Quartus in Drive C, assuming that you are using Windows 10 or you have UAC enabled, windows security settings could be interfering with the process. Starting a cmd session as admin and test with that to see if it bypasses the problem.

Did you try running the "aocl-clang" executable manually and see what happens as suggested by the original error message?

Hi, i have the same issue but in Ubuntu environment. When i did execute "aocl-clang" manually the system reported:

error while loading shared libraries: libmip_common.so: cannot open shared object file: No such file or directory
Now, i'm trying to solve this missed library

That library is shipped with Quartus itself. Either your installation is incomplete or you have not added the path to the libraries required by the OpenCL compiler to LD_LIBRARY_PATH.

    Did you try the existing suggestions? Specifically, running the aocl-clang binary directly to see what error message it will print?

I also encountered this problem, but it has been solved. Everyone may have a different reason for this problem. Let me talk about my situation.
I encountered this situation because the system environment variable PATH lacks the following path:
C:\Windows\system32
C:\Windows
C:\Windows\System32\Wbem
As for why the lack of these will lead to this problem, emmmm, maybe, I don't know, and if it causes this problem, you should also find that command shutdown will be invalid at the command prompt.
