New ContributorThank you for your reply!
My BSP version is v17.1.0. I tried to compile the host pipe kernel with AOC v18.0, BSP v17.1.0 and Quartus 17.1.0.240, but the compiler gave me error message at the very beginning:
aoc: This release of the Intel(R) FPGA SDK for OpenCL(TM) requires ACDS Version 18.0.0 (64-bit). However, the following version was found:
Quartus Prime Shell
Version 17.1.0 Build 240 10/25/2017 SJ Pro Edition
The AOC v18.1 Getting Started Guide (page 6) states AOC v18.1 only has backward compatibility with BSP v18.0 and BSP v17.1.1, but not BSP v17.1.0. However, is there any Quartus 17.1.1? From the Quartus Pro download page, it seems that v17.1.0.240 is the only version under 17.1 family.
The AOC v17.1 programming guide did state that cl_intel_fpga_host_pipe is supported, but it's weird that I still got the unknown pragma warning.
Frequent ContributorYou should never mix different versions of Quartus and AOC. Are you using the Arria 10 reference board? If that is the case, there is a compatible BSP shipped with every version of Quartus for that board.
There is indeed Quartus v17.1.1 and v17.1.2. However, I am not sure if v17.1.1 is available for download anymore. On the download page for Quartus v17.1.0, there is an "Update" tab. You can find the v17.1.2 update there. There are multiple improvements to the host pipe API mentioned in the changelog for v17.1.1, maybe support for host pipes was not complete/working correctly in v17.1.0.
