Make libTensorFlow C++ library work for the latest M1 Mac

[EricTheRed20]

The M1 Mac with it's own non-Intel processor was released ten months ago but is still not supported by the libTensorFlow C++ library https://www.tensorflow.org/install/lang_c. It would be good to get that done so that we can release apps for the Mac. As far as I know TensorFlow does work for the M1 Mac in Python.

You can test the library file compatibility by running xcrun as follows:-
Run the XCode command: xcrun lipo -info "libtensorflow.dylib" and it returns "libtensorflow.dylib is architecture x86_64".

For it to support the Intel Mac and the M1 Mac it should return "libtensorflow.dylib are: arm64 x86_64" (ie. both formats so that the compiler can build the app for Intel, Arm or both (the default)).

Hi @Eric2016Lv !
We see that the issue template has not been filled, could you please do so as it helps us analyse the issue [tf version, steps followed before you ran into this error or stand alone code/colab gist to reproduce the issue faced].Thanks

[EricTheRed20]

Sorry, can't see an "issue template". Sorry don't use colab. The issue is quite clear:- The C++ library ( https://www.tensorflow.org/install/lang_c ) doesn't work for the new Mac released almost a year ago.

Hi @EricTheRed20! ,Sorry for the late response.
Could you please look at the answer of these threads thread1 ,thread2 for now. It suggests building Tensorflow C++ using Bazel .

[EricTheRed20]

Thanks for that. Neither of those links give a solution. They are both for TensorFlow "Lite" which is a cut down version of the full library. Unfortunately TensorFlow "Lite" doesn't have the full functionality required and the full libTensorFlow C++ library is needed.

Hi @jvishnuvardhan ! Could you please look into this issue!
