I have solved the above problem by exporting environment variable as following export QUARTUS_ROOTDIR=/home/guta/18.1/quartus export INTELFPGAOCLSDKROOT=/home/guta/intelFPGA/18.1/hld export PATH=$PATH:"$QUARTUS_ROOTDIR"/bin: "$INTELFPGAOCLSDKROOT"/linux64/bin:"$ALTERAOCLSDKROOT"/bin:/home/guta/intelFPGA/18.1/embedded/ds-5/bin export LD_LIBRARY_PATH="$INTELFPGAOCLSDKROOT"/linux64/lib

export AOCL_BOARD_PACKAGE_ROOT="$INTELFPGAOCLSDKROOT"/board/de1soc export QUARTUS_64BIT=1 reference is link https://www.terasic.com.tw/attachment/archive/836/DE1SOC_OpenCL_v02.pdf
