Have you updated the Git submodule? A submodule called vccc is being used. Run git submodule update after git submodule init.

@cyborgdennett

1. Have you built your own libtensorflow-lite.a ? If so, what version of tensorflow and emsdk were used for building it?
2. Have you checked the version of emsdk mentioned in the Readme? I think the version of emsdk you used does not match what I used for building the sample
3. I haven't checked if the newer versions of emsdk are working well with the compiled libraries and the code. I think you must build your own tflite and opencv to build the sample with the newer versions of emsdk

@Dabin22 Yes, I updated the submodules, which did not work.

@leeyongeun9 I have emcc version 3.1.5

For the rest I have not build anything other than the default install commands.

I will try building tflite and opencv with new emcc now.
