Compiling and Linking Your Kernels or Object Files without Building Hardware (-rtl) which don't work !

[caron]

when I use " aoc -rtl <your_kernel_filename1>.cl". it issue an error :

aoc: Running OpenCL parser....

error: unknown argument: '-rtl'

Error: OpenCL parser FAILED.

Refer to hello_world/hello_world.log for details.

I would guess you are using an older version of the compiler in which the -rtl switch was not available. This switch was added in v18.0 or 18.1 (don't remember exactly).

Hi Caron,

May I know what version you are using?

Thanks.

Hi , thank you for your response !

my version is :

Intel(R) FPGA SDK for OpenCL(TM), 64-Bit Offline Compiler

Version 17.1.1 Build 273

Copyright (C) 2017 Intel Corporation

Maybe it is the version's problem.. How can I update the version ?? thank you .

Indeed the -rtl switch is not available on Quartus v17.1.x. You can download all versions of Quartus from here:

https://www.intel.com/content/www/us/en/programmable/downloads/download-center.html

However, you should make sure to use a version of Quartus that is compatible with the OpenCL BSP of your board. Consult the documents from your board manufacturer to determine what version of Quartus to use.

Hello KhaiY_Intel,

I have the same issue with this version :

Intel(R) FPGA SDK for OpenCL(TM), 64-Bit Offline Compiler

Version 19.1.0 Build 670 Standard Edition
