make error with tensorflow

[flankechen]

I am working with tensorflow and success in bazel build. I do have libtensorflow_framework.so libtensorflow.so in /usr/local/lib/ and I verify this with a toy .c file with

#include <stdio.h>
#include <tensorflow/c/c_api.h>

int main() {
  printf(“Hello from TensorFlow C library version %s\n”, TF_Version());
  return 0;
}

and gcc -I/usr/local/include -L/usr/local/lib hello_tf.c -ltensorflow and it runs as expected

but in this project, I got these errors like:

I think there is something missing in linking tensorflow in test.o

@ybao2016 thanks for your reply, in face, I switch to this repo and it works .

Thanks. the above fix clears the error. I also added export MTCNNLIBDIR=~/FaceDetection/libmtcnn But this project is clean for Tensorflow.
