librubberband.a(rubberband-c.dev.o)' does not contain bitcode for iOS #26

Closed faiziakbr closed 3 years ago

faiziakbr commented 4 years ago

I am writing C++ to C wrapper for rubberband to use it in my IOS project. I am getting BitCode error.

librubberband.a(rubberband-c.dev.o)' does not contain bitcode. You must rebuild it with bitcode enabled (Xcode setting ENABLE_BITCODE), obtain an updated library from the vendor, or disable bitcode for this target. for architecture arm64

This is my code

#include "Wrapper.hpp"

#include "rubberband-c.h"
#include "RubberBandStretcher.h"

using namespace RubberBand;

extern "C" int myMethod() {
    rubberband_new(48000, 1, RubberBandOptions(), 2.0, 20.0);
    return 2;
}

If disable the bitCode i get 27 errors and 1 warning.

Any clue how i can solve this issue?

My understanding (as a non-iOS developer) is that you can ask the compiler to include bitcode with the -fembed-bitcode argument.

I've tried adding this to the end of the ARCHFLAGS_DEV and ARCHFLAGS_SIM definitions in Makefile.ios within the Rubber Band source tree, and I can confirm that compilation succeeds, although I haven't tested whether the resulting library still works!

Provisionally I'm adding this argument in the repo - would appreciate any views from other readers on the merits of it.
