aocl clang exists but not working

[mvemp]

I am trying to install the new version v18.1 AOCL. I was able to install quartus pro setup and aocl pro setup file.

When I execute aoc kernel.cl, I get error

" Error: aoc: Executable /opt/FPGA/hld/linux64/bin/../../llvm/bin/aocl-clang exists but is not working!

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

and when I execute /aocl-clang I get this error

./aocl-clang: error while loading shared libraries: libdsdk.so: cannot open shared object file: No such file or directory

Any idea about this?

My path : echo $PATH

/opt/FPGA/hld/bin:/opt/FPGA/quartus/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

My Library path :

echo $LD_LIBRARY_PATH 

/opt/FPGA/hld/linux64/lib/:/opt/FPGA/hld/board/a10_ref/linux64/lib:/opt/FPGA/hld/host/linux64/lib:

You have an extra colon at the end of your LD_LIBRARY_PATH; hence, the last path becomes "/opt/FPGA/hld/host/linux64/lib:" instead of "/opt/FPGA/hld/host/linux64/lib" which is invalid. I was scratching my head for 5 minutes as to why your configuration is not working even though it should, until I saw the colon. 😅

I tried changing that.

echo $LD_LIBRARY_PATH

/opt/FPGA/hld/linux64/lib:/opt/FPGA/hld/board/a10_ref/linux64/lib:/opt/FPGA/hld/host/linux64/lib

but still same error. I have seen lib files in all these three paths

/opt/FPGA/hld/linux64/lib$ ls

I really dont see libdsdk.so

Do you have this libdsdk.so file in any of your paths? May be my installation is wrong.

[HRZ]

On my environment that file is located at "*installation_dir*/hld/linux64/lib/". However, I do NOT have that folder added to my LD_LIBRARY_PATH and everything seems to work correctly as it is.

@mvemp​ 

Are you still facing this issue or you are able to proceed ?

May I know what version of Linux distribution you are using ?

Thanks,
