Error: aoc: The Intel®  Kernel Builder for OpenCL™ compiler (ioc64) can not be found


Due to a problem in version 19.1 and 19.2 of the Intel® FPGA SDK for OpenCL™, if you compile your OpenCL project for emulation by adding -fast-emulator, Errors may occur as following:
Error: aoc: The Intel® Kernel Builder for OpenCL™ compiler (ioc64) can not be found

This is because for fast emulator support, the "Intel SDK for OpenCL Applications" must also be installed. It is separate from the Intel® FPGA SDK for OpenCL™.


To work around this problem, you must download and install the correct version of the "Intel SDK forOpenCL Applications"
