ERROR: CL_INVALID_KERNEL_NAME - ERROR: CL_INVALID_KERNEL_NAME Description If you run vector_add opencl example design on Intel® Programmable Acceleration Card with Intel® Arria®10 GX FPGA . An error may occur as follows: [root@localhost vector_add]# ./bin/host Initializing OpenCL Platform: Intel(R) FPGA SDK for OpenCL(TM) Using 1 device(s) pac_a10 : PAC Arria 10 Platform (pac_a10_f100000) Using AOCX: vector_add.aocx Context callback: Specified kernel was not built for any devices ERROR: CL_INVALID_KERNEL_NAME Location: host/src/main.cpp:169 Failed to create kernel Segmentation fault (core dumped) Resolution You should check if your initialization script file (for example the init_env.sh file) has the following enironment variables set: CL_CONTEXT_COMPILER_MODE_ALTERA=3 CL_CONTEXT_COMPILER_MODE_INTELFPGA=3 To work around this problem, you should unset the environment variables , and try running the host again.
