Tensorflow c++ api未定义引用`tflite::DefaultErrorReporter()'答案

【问题描述】：

我在 Ubuntu 16.04 上使用静态构建成功构建了 tensorflow_cc。

我正在测试我从 tflite 指南中获取的一个小代码：

  $> cat test1.cpp

  #include <cstdio>
  #include "tensorflow/lite/interpreter.h"
  #include "tensorflow/lite/kernels/register.h"
  #include "tensorflow/lite/model.h"

  using namespace tflite;

  int main(int argc, char* argv[]) {
  if (argc != 2) {
  fprintf(stderr, "minimal \n");
  return 1;
  }
  const char* filename = argv[1];

  std::unique_ptrtflite::FlatBufferModel model =
  tflite::FlatBufferModel::BuildFromFile(filename);
  return 0;
  }

我收到此错误：

  [ 50%] Building CXX object CMakeFiles/example.dir/example.cpp.o

  CMakeFiles/example.dir/example.cpp.o: In function main': example.cpp:(.text+0x57):

对如何进行有什么建议吗？

【解决方案1】：

已在https://github.com/tensorflow/tensorflow/issues/36661 上回复由于某些奇怪的原因，您需要先向链接器提供目标文件而不是 tflite 库。
