Lexical or Preprocessor Issue - "ipp.h" file not found



  • Hi,

    I'm having troubles building HISE on Mac. This is what I did (I followed @d-healey's tutorial):

    • I installed Catalina because the latest version of Intel IPP (I created a Time Machine Backup with Mojave, just in case);
    • I installed the new version of Xcode (then I tried with the v11.13 and the v10.3.. same problem);
    • I downloaded the SDK files and placed them in the right folder (tools/SDK);
    • I installed the latest version of Intel IPP (not all the Intel oneAPI Base Toolkit, but just the Intel Performance Primitives);
    • I opened Projucer and then the HISE Standalone.jucer project;
    • I changed the OS X Architecture to 64-bit Intel;
    • I clicked "Save Project and Open in IDE" and then "Build for Running".

    Now it's when I got the problem: Lexical or Preprocessor Issue - "ipp.h" file not found

    I read many similar threads on the Forum but unfortunately I didn't find the right solution for me. I thought it wasn't finding the IPP, even if the paths seemed correct, so I tried to move them around with no success (sometimes even with more errors).

    The paths are:

    • Header search paths: /opt/intel/ipp/include
    • Extra library search paths: /opt/intel/ipp/lib

    Thanks in advance to anyone who can help me out! (also thanks @d-healey for the great tutorials, about Kontakt too!)



  • Build without IPP, it seems the latest version is currently unusable with HISE



  • @d-healey Thanks! I thought that was the problem.

    In the meantime I found an old version of IPP uploaded by @DanH which made my day! Not errore anymore! I hope @DanH will allow me to share the link here in case someone else will have the same problem: https://www.dropbox.com/sh/4gx74wg1jpfnk7r/AACkGmy8SdV-j0qsiw5VFYFza?dl=0



  • @Maichol with Catalina you have to move folders from / opt / intel / ipp and it will work.



  • @yall do you mean that the paths should be?:

    • Header search paths: /opt/intel/ipp
    • Extra library search paths: /opt/intel/ipp

    So you're using Catalina, the v12.4 Xcode and the latest IPP?



  • @Maichol I just read that you downloaded the latest version of ipp as a first step. I had encountered the same problem as you at the beginning.
    in fact, when you go to projucer in the export module it seems to me, you have all the paths which correspond to ipp either / opt / intel / ....
    if you check these paths in your mac having downloaded the latest version of IPP, you would not get the same paths. that's why you have to move the folders to / opt / intel .... I'm writing this from memory I don't have my mac handy to check. but try looking at the paths in projucer, then check in mac search if the paths match. older versions of IPP went straight to the right place, but the newer version hides in another folder.



  • @Maichol i am using catalina and xcode 11.3 i believe. (I only use mac to export my plugins created under windows which is much faster ^^)
    I did not manage to compile with xcode 12.2



  • @yall Ok, I think now I get what you mean. The path in my Mac was something like "/opt/intel/2021.1/ipp" (I'm writing this from memory too since I installed the old version of IPP and everything works now) and I tried to change the path in Projucer with this one but it didn't work. Maybe I should have done the opposite like you said, moving the ipp folder directly into the intel folder to match the path of my Mac to the one in Projucer (if I understood right).

    Anyway, now it's working with the old IPP, do you think it would be better to have the latest version? or it's the same?

    Thanks for your time!



  • @Maichol I do not know. I suppose the more recent the better ^^ if you have a 1980 ipp version, the 2019 will necessarily be better ^^



  • @Maichol Yes you have to do the opposite and move the folders, leaving the path in Projucer as is. This will get HISE to compile but I think compiling plugins will still fail (certainly does on Windows). Stick with the old version until someone finds a solution.

    I prefer 1933 King Kong to 2005 King Kong. Newer is not always better 😛



  • @d-healey It's true, let's take the example of polar bears, it was better before ^^

    Good point!ahah

    Just for the science I tried 2020 IPP with 12.4 Xcode and it doesn't work. So I think I'll stick with this IPP but with an older Xcode since it was working before.
