Hi Paul,
Thank you for reporting this issue. APP SDK 3.0 is quite old, so I don't think APP SDK was tested with the newer cards like vega. Also, it might be a driver issue too. Anyway, I'll report the problem to the concerned team. Please share the clinfo output.
Btw, may I assume that you observed this errors with the pre-built sample binaries available in APP SDK?
To understand the issue better, it would be helpful if you try some older drivers and let us know your observation.
FFT returns 31 compile errors, top one being " unknown type name 'class' ", rather obvious that CL 2+ isn't working there...
FFT kernel contains static c++ code, hence compilation flag "-x clc++" is used to build the kernel. From the above error, it looks like the compiler failed to recognize the static c++ code.
P.S. You have been whitelisted now.

Re: Various CL faults with vega on windows...
This is the clinfo for vega by itself (+CPU), I cant currently provide the clinfo for the vega+hawaii config atm as the hawaii's unplugged...

Thank you for sharing the clinfo output.
Regarding the compilation error, it looks like the opencl compiler does not support static c++ for Vega devices, hence the compilation is failing with those errors. I'll check with the compiler team and confirm.
apparently the forums has some auto-formatting that messes with the info..
Advanced editor [via "Use Advanced editor" option] can be used for controlling the format. It also provides file attachment option which is useful for large contents.

right... for some reason I didn't see the advanced option...

Here is an update. The compiler team has confirmed that static c++ is no longer supported on vega. Actually, OpenCL compiler uses a different toolchain for newer generation GCN devices compared to older cards and hence, some features may no longer be available on those devices. As a result, some of the APP SDK samples (e.g. FFT) may fail on vega.
Regards,
