Why a warning occurred when I made the opencl example-"board_test" for DE1-SOC

I am running some opencl project examples with de1-soc,and I have problem when I make the host program of "board_test"(the example provided by ALTERA).

As shown in the picture below,a warning occurred. I am sure I have set all the essential environment variables and I didn't change any makefile or code files . The aocl

version is 16.0.0.211.

Does this warning matter ? How to kill it?

    There is something wrong with your "LD_LIBRARY_PATH". It is not pointing to all the necessary libraries needed for compilation. Find the "libacl_emulator_..." file and make sure it is included in your LD_LIBRARY_PATH environmental variable.

    Thanks for your reply!

    The " libacl_emulator_kernel_rt.so " was not found in the LD_LIBRARY_PATH , so I copy the " libacl_emulator_kernel_rt.so " to the path ("$ALTERAOCLSDKROOT"/linux64/lib), yet it doesn’t

    work. The same warning occurred.

    My environemnt variables setting is :

    "

    export QUARTUS_ROOTDIR=/home/fpgaopencl/Software/Quartus_ii_16.0/quartus

    export ALTERAOCLSDKROOT=/home/fpgaopencl/Software/Quartus_ii_16.0/hld

    export PATH=$PATH:"$QUARTUS_ROOTDIR"/bin:"$ALTERAOCLSDKROOT"/linux64/bin:"$ALTERAOCLSDKROOT"/bin:/home/fpgaopencl/Software/Quartus_ii_16.0/soc_eds/embedded/ds-5/bin

    export LD_LIBRARY_PATH="$ALTERAOCLSDKROOT"/linux64/lib

    export AOCL_BOARD_PACKAGE_ROOT="$ALTERAOCLSDKROOT"/board/terasic/de1soc

    export QUARTUS_64BIT=1

    export LM_LICENSE_FILE=/home/fpgaopencl/Software/Quartus_ii_16.0/hld/license.dat "

    If you are cross-compiling for an ARM SoC, you should have the ARM libraries in your path. You should NOT copy the library file to your existing LD_LIBRARY_PATH, you should add the path to the library file to LD_LIBRARY_PATH; there might be other libraries in the same path that are needed for correct compilation/linking. You should also add the path to the library file in the BSP that is provided by the board manufacturer to LD_LIBRARY_PATH.

    Sorry to reply so late to you ! Something was wrong with my linux virtual machine.I had to reconstruct my environment and I decided to choose the version 14.0. Everything goes well on the version 14.0 (quartus、AOCL、and BSP). I found Terasic have not updated the PDF for the version 16.0 . I will contact with the Terasic support to ask some question.
