using ios_simulator results in an empty lib !

simdax commented 2 years ago

Hello all

I'm on macOs (Ventura 13.0)

I have some difficulties to build essentia for ios-simulator actually I've made all the necessary glue, calling a simple essentia::init() to test the basis.

But XCode is telling me it can find any symbols And indeed, it appears that the resulting lib may be defectuous ?

when doing a ranlib, I've this bad message:

/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: i386 file: build_ios/src/libessentia.a(essentiautil.cpp.1.o) has no symbols
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/ranlib: for architecture: x86_64 file: build_ios/src/libessentia.a(essentiautil.cpp.1.o) has no symbols

I join the lib and the log if it can help

Thank you :)

and the exact cmd:


CC=clang CXX=clang++ python3 waf configure \
-o build_ios --arch=i386        \
--build-static --with-tensorflow --lightweight= --fft=ACCELERATE --cross-compile-ios-sim \
--include-algos="FFT,TriangularBands,Spectrum,Windowing,MelBands,Magnitude,NoiseAdder,UnaryOperator,TensorflowInputMusiCNN,TensorflowPredictEffnetDiscogs,TensorflowPredict,PoolToTensor"

python3 waf
ranlib build_ios/src/libessentia.a

I need the tensorflow binding, as the algorithm which interests me is in it. (but in fact it changed nothing to remove it)

I've tried also with and without arch=i386

which results in

I've removed TensorFLow , but it does not seem to be the main problem

building without tf create the same problem

python3 waf configure \
-o build_ios         \
--cross-compile-ios-sim \
--lightweight= --fft=ACCELERATE \
--build-static

Can we find a basic xcode exemple with a working ios_simulator essentia linked ???
