AOC compile emulation error

[polasz]

Hi everyone,

I am using Quartus Prime Pro version 20.4 and am trying to build for emulation, when I build the hello world example via:

aoc -march=emulator -v hello.cl

I get the output:

aoc: Selected target board package
aoc: Selected target board
Error: OpenCL kernel compilation FAILED

And that's it, there is a ioc.log file created but it is empty and I have set CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA environment variable, but I think that's only needed for running anyway.

Has anyone seen this before, and/or is there a way to get more detailed error reporting from aoc to try and figure out what the error is? For instance is it possible to view what commands are being issued by the aoc wrapper script?

Thanks,

Nick

Hi polasz,

You can try this as example instead:

Thanks.

Hi,

Thanks very much Aik Eu, we have been playing with this and found that it was because we had incorrectly set the PATH environment variable so it did not point to hld/llvm/aocl-bin directory correctly. When including that in the path it all works now for us  

I post this here in-case it is helpful to anyone in the future who is getting a similar issue

Cheers,

Nick
