where is SDK_Invert_ProcAmp_Kernel.metal.h in the new sdk

[urbeller]

Hello,

In the attempt of testing the new Metal support on mac, I downloaded the updated SDK but it doesnt build. It seems like the file SDK_Invert_ProcAmp_Kernel.metal.h is missing. Can you please tell me where to find it and if there is any recommendations to build a metal based plugin. thank you.

I have a similar issue with the build of SDK_Invert_ProcAmp on OSX. 

This build step errors:

File "SDK_Invert_ProcAmp/Mac/../../../GPUUtils/CreateCString.py", line 52, in <module>

with open(inputfile, 'r') if len(inputfile) > 0 else sys.stdin as f:

IOError: [Errno 2] No such file or directory: 'Build/Intermediates.noindex/SDK_Invert_ProcAmp.build/Debug/SDK_Invert_ProcAmp.build/DerivedSources/64/PreprocessedOpenCL/SDK_Invert_ProcAmp_Kernel.i'

It's correct, inside the location there is no SDK_Invert_ProcAmp_Kernel.i, just SDK_Invert_ProcAmp_Kernel.metal.h.

So it seems SDK_Invert_ProcAmp_Kernel.metal.h is created on build. Any idea about the .i file?

I forgot to follow these steps, now it builds fine:

Thank you ! indeed it works. I didn't realize that the metal shader file was actually generated...rather translated from cuda. thank you again.
