Cant build with IPP, but I could the last 2 yrs.

[andioak]

@d-healey Did the Intel IPP have a non-GNU compatible license? I thought it was just in case intel cpu:s were present, use IPP.

So does the FFTW3 have the same advantages over the default fallback, Kiss FFT?

Why is this not in the Readme.md?

[d.healey]

@andioak IPP is proprietary so (I assume) is incompatible with GNU GPL. You can also use it with AMD CPUs. FFTW3 is about equal with IPP (there are some old benchmarks on the FFTW3 site) but it varies, sometimes IPP is faster, sometimes FFTW is, it depends on the exact workload.

[andioak]

@d-healey Ok, thanks for the info.

Is there a way to get that into the main (master branch) md doc, you think? That would definitely be a thing to know ahead of building your first setup and definitely your first plugin. (assuming it is correct that it does not marry with a GNU license, that is :) )

Make a pull request :)

Setting up FFTW3 on Windows is more complicated than IPP :D

If the licenses do not marry, it does not matter, you could not use IPP anyway. If a license of IPP does not work to deliver a software or plugin with GNU end licenses, then why is it included in HISE?

[d.healey]

@andioak IPP isn't included with HISE.

I just read that the GNU GPL contains some kind of linking exception. So perhaps that can apply to using the IPP with a GNU GPL plugin. Still I would avoid including any proprietary components in a free software app.

Dough! Haha, no it isn´t included, you're right. IPP is just implied as a somewhat good performance enhancement addition.

Okay, I found few examples of (to me less understandable) comparisons of IPP vs FFT3W, but this one of the KissFFT and FFTW3 has some single-precision bumps of around 2-7x the speed:

3.0 GHz Intel Core Duo, Intel compilers, 64-bit mode

I just read that the GNU GPL contains some kind of linking exception. So perhaps that can apply to using the IPP with a GNU GPL plugin.

I would worry about the opposite order here, the IPP license's reservations to be delivered within the GNU GPL. But of course, GPL-v3 is nasty in its allowances of differences in open:ness, so perhaps your worry is more warranted.

Still I would avoid including any proprietary components in a free software app.

I agree entirely.

@BWSounds did you solve this? Having the same issue

[Christoph Hart]

@DanH I think I've updated the IPP integration to the recent version (it's now using something called OneAPI), but this might not work with older IPP versions. Try updating IPP and see if it helps.

Unfortunately you can't download older IPP versions, so I have to stay at the latest versions with HISE.

Oh and if you reinstall IPP make sure to enable the VisualStudio integration for all VS versions you have on your system, this is required for it to compile.

[DanH]

@Christoph-Hart ah ok, will give it a bash, thanks

[d.healey]

@DanH I show the oneAPI install in this video

[DanH]

@d-healey thanks :)

[DanH]

@d-healey alrighty, followed the vid step by step, cleaned the Hise builds folder, tried to build Release and it can't find the ipp.h file now... Any ideas?

I never uninstalled the old ipp - I don't know if that makes any difference.

[d.healey]

@DanH Did you select the oneAPI thingy in projucer?

[DanH]

@d-healey 'Use IPP Library (oneAPI)' ?

Yes, I followed every step.

[d.healey]

@DanH Maybe you need to remove the old one then. Since you installed IPP after Visual Studio there is probably some extra step required to link them together.

[DanH]

@d-healey well there's the step at the end of installing ipp via OneAPI that asks which version of VS you want to use it with and I checked the only option (2017)... but yeah, possibly something else

I also see no option to remove the old one!

[DanH]

@d-healey do you not install ipp after VS in your video as well?!

Oh yeah you're right, it's been ages since I looked at it :)

[Matt_SF]

@DanH I have a new HD with a brand new system, and also followed @d-healey 's video to be sure I was doing it right (never hurts to listen to the masters ). But I getting the same error. Indeed it used to work in the past.

I'm currently over-busy so I didn' t find time yet to try things out. I'm using VS2017 so maybe I'll give VS2022 a shot... I don't know if that will help...
