dyld: Library not loaded: @rpath/libngraph.dylib on MACOS

Hi,

I've successfully complied the hello_classification c++ sample, but when i ran the app it showed the following error

dyld: Library not loaded: @rpath/libngraph.dylib

  Referenced from: /opt/intel/openvino_2021.3.394/deployment_tools/inference_engine/lib/intel64/libinference_engine.dylib

  Reason: image not found

I've checked my libngraph.dylib is located in 

/opt/intel/openvino_2021.3.394/deployment_tools/ngraph/lib

And I've tried the install_name_tool method but it did not work.

Appreciate any other solutions. Thanks

Hi Zihao Guo,

Thank you for reaching out. I found out the same issue reported on the Apple Community and this kind of error is because of the different project configurations that amend a framework build for the app.

Thus, what I can suggest avoiding the error is, you can run the following commands to add rpath to myriad_compile, and to remove the code signature:

1. MYRIAD_COMPILE=<INSTALL_DIR>/openvino_2021/deployment_tools/inference_engine/lib/intel64/myriad_compile
2. sudo install_name_tool -add_rpath $(dirname $(find <INSTALL_DIR>/openvino_2021 -name libngraph.dylib)) $MYRIAD_COMPILE
3. sudo codesign --remove-signature $MYRIAD_COMPILE

After that, try to recompile the hello_classification c++ sample.

Regards,
