Mojave Xcode 9.4.1

[Christoph Hart]

Mojave dropped 32bit support and it looks like you're using an old IPP library.

There's a few topics about this problem here, just search for Mojave 64bit or something like that.

[hisefilo]

@Christoph-Hart Will search. Using last IPP downloaded yesterday!

Found the best explanation from @dustbro here:

https://forum.hise.audio/topic/925/i386-deprecated/10

[hisefilo]

@Christoph-Hart Yes remember that! Weird thing is Scriptnode branch compiles. Master does not. I don't want to jump into Scriptnode because still being updated daily. I guess some commit between them will work.

[d.healey]

@hisefilo Don't use the master branch on a Mac. There is a bug where exported plugins won't trigger samples on MIDI input. Use Scriptnode.

[hisefilo]

@d-healey Thanks mate!

[hisefilo]

@d-healey got this when exporting VST/AU on Scriptnode. I still want yo support 32bit on Mac (or there's no one using it?)

** BUILD FAILED **

[Christoph Hart]

You can't compile a 32bit binary with Mojave. If you want to support 32bit, you need a Mac with an older OS and build your final binaries there.

[hisefilo]

@Christoph-Hart Oh I see. Still there any Mac 32bit users in your experience??

[Christoph Hart]

I didn't release a 64bit binary just yet (also my build server is using Sierra and will continue to do so until it doesn't work no longer), so I can't say anything about this.

However my educated guess is that it's less than 1% of mac users.

[d.healey]

@Christoph-Hart If I build a 64bit plugin on Mojave will it work on older versions of MacOS? and the same question for Win10 and older versions of Windows?

[hisefilo]

IMPORTANT. On MacOS Mojave: Use IPP first release from 2019. newer ones will give ipp error on compiling.

[hisefilo]

@d-healey AFAIK will run. Since MacOS is 64 from 10.7 (like 10 year ago)
