Describe the problem

I followed the instructions to install the Mediapipe framework described here (including building the "Hello World" example). Then, I followed the instructions to build the "Hand Detection solution" using these instructions. The build failed due to a Linker error (see the output log).

[chojuahn]

For some reason the function body TfLiteOpaqueContextReportError inside mediapipe_cpp\bazel-mediapipe_cpp\external\org_tensorflow\tensorflow\lite\core\c\c_api_opaque.cc not built?

[Stoyan-I-A]

Same issue when building face_mesh

Indeed, I wasn't able to build any of the examples other than "Hello World".

face_detection is buildable as is

[Stoyan-I-A]

@chojuahn You are right! I didn't try this one. I had to mess around with the files afterwards to launch the .exe but it does build indeed.

A workaround, comment out here

This is also breaking MediaPipe's Python build for Windows. I am trying to track it down.

The offending commit is tensorflow/tensorflow@d6e25b0, though there doesn't seem to be an obvious problem with it.
