I install the right one ,not the runtime ,so I don't have /opt/altera/aocl-pro-rte/aclrte-linux64.

and here is my init_openvino.sh

source /home/jiangjn/tools/inteldevstack/init_env.sh
export CL_CONTEXT_COMPILER_MODE_ALTERA=3
export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3
export INTELFPGAOCLSDKROOT="/home/jiangjn/tools/inteldevstack/intelFPGA_pro/hld"

Dear junning, jiang,

Are you using a supported FPGA board ? Which FPGA kit are you using ?

Thanks,

Shubha

I have the same issue.   link：https://software.intel.com/en-us/forums/computer-vision/topic/808441

I install the dev(18.2GB) ,not the runtime(200MB) ,so I don't have /opt/altera/aocl-pro-rte/aclrte-linux64. 

and here is my init_openvino.sh

how can i do to solve this problem

source ***/tools/inteldevstack/init_env.sh
export CL_CONTEXT_COMPILER_MODE_ALTERA=3
export CL_CONTEXT_COMPILER_MODE_INTELFPGA=3
export INTELFPGAOCLSDKROOT="***/tools/inteldevstack/intelFPGA_pro/hld"

Dear junning, jiang

The error message is because you aren't using the right version of OpenCL RTE.  You should install the version that comes with OpenVINO, 18.1.1. 

The fact that R5 works fine, means that you still have OpenCL RTE 17.1.1 installed.   You need to uninstall the old version and cleanly install the new one.

Hope it helps and sorry it took so long for me to respond.

Thanks for using OpenVino !
