aocl clang exists but not working

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

    __ocl_svml_e9.so clbltfne9_img_cbk.rtl emu_libs libaoc_clang_decrypt.so libelf.so.0

    __ocl_svml_h8.so clbltfnh8.rtl libOclCpuBackEnd.so libaxerces-c.so libintelocl.so-gdb.py

    __ocl_svml_l9.so clbltfnh8_img_cbk.rtl libOclCpuDebugging.so libaxerces-c.so.26 libintelocl_emu.so

    __ocl_svml_z0.so clbltfnl9.rtl libOpenCL.so libcl_logger_emu.so libtask_executor_emu.so

    clbltfne9.rtl dspba libalterahalmmd.so libelf.so

    libaltera_a10_ref_mmd.so

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

    libOpenCL.so libaltera_mpfr.so libaoc_cosim_mmd.so libelf.so.0 libzmq.so.1

    libOpenCL.so.1 libaltera_mpir.so libaoc_cosim_msim.so libz.so libzmq.so.1.0.1

    libOpenCL.so.2.0 libalteracl.so libaoc_cosim_msim32.so libz.so.1 sources

    libacl_emulator_kernel_rt.so libalterahalmmd.so libelf.so libzmq.so

    I really dont see libdsdk.so

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

    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,
