Hi!

I am back to try to learn how to use Csound API on  iOS.

The Examples project works, but when I am following the instructions on:

https://flossmanual.csound.com/csound-and-other-programming-languages/csound-in-ios

to create my own Xcode project

everything goes fine until when building the app. The error reported is:

Undefined symbols for architecture arm64:

  "_vDSP_create_fftsetup", referenced from:

      _csoundRealFFT2Setup in libcsound.a(fftlib.o)

  "_vDSP_destroy_fftsetup", referenced from:

      _setupDispose in libcsound.a(fftlib.o)

  "_vDSP_fft_zrip", referenced from:

      _csoundRealFFT2 in libcsound.a(fftlib.o)

      _vDSP_DCT_execute in libcsound.a(fftlib.o)

ld: symbol(s) not found for architecture arm64

For any case I copy the linker command below.

I had the same when I was trying to link a Qt C++ project against libcsound.a

When I checked libcsound.a to see which symbols are in there:

 nm -a /Users/tarmojohannes/Documents/src/csound-iOS-6.18.0/Csound\ iOS\ Obj-C\ Examples/csound-iOS/libs/libcsound.a | grep _vDSP 

it seems to be correct:

---------------- T _vDSP_DCT_execute

                 U _vDSP_create_fftsetup

                 U _vDSP_destroy_fftsetup

                 U _vDSP_fft_zrip

I did not find out how to check about the architecture.

This is the official csound-ios-6.18.0 package downloaded from Csound web site.

I tried also to build the iOS folder from sources myself but it failed, since weather the option

-T buildsystem=1 

bothered make or without it I got error:

CMake Error in CMakeLists.txt:

  The custom command generating

    /Users/tarmojohannes/Documents/src/csound-6.18.1/iOS/cs6iOS/csound_orclex.c

  is attached to multiple targets:

    CsoundLib

    CsoundLib-static

  but none of these is a common dependency of the other(s).  This is not

  allowed by the Xcode "new build system".

I had the same problem some months ago and then gave up. Can someone who knows more about the iOS development test the libcsound library?

The strange thing is that the demo project builds, so there might be some flags or settings I cannot guess that must be given..

Thanks!

I never tried the public release of the iOS library. I have always built my own. I can email you a link to the library I am using if you like?

Thank you, Giovanni, Victor!

That was it! Including Accelerate Framework did the trick and I got the project building. 

Without the hint I would really never ever have guessed it. I suggest some lines in the documentation (csound_ios_manual.pdf 2.3 Getting started with Your Own Project) about it would be absolutely in place.

Next step is to try it make it happen also in a Qt project.

Best!

This is the official csound-ios-6.18.0 package downloaded from Csound web site.

I tried also to build the iOS folder from sources myself but it failed, since weather the option

-T buildsystem=1 

bothered make or without it I got error:

CMake Error in CMakeLists.txt:

  The custom command generating

    /Users/tarmojohannes/Documents/src/csound-6.18.1/iOS/cs6iOS/csound_orclex.c

  is attached to multiple targets:

    CsoundLib

    CsoundLib-static

  but none of these is a common dependency of the other(s).  This is not

  allowed by the Xcode "new build system".

I had the same problem some months ago and then gave up. Can someone who knows more about the iOS development test the libcsound library?

The strange thing is that the demo project builds, so there might be some flags or settings I cannot guess that must be given..

Thanks!
