我想调试用Bazel生成的可执行文件.使用Bazel生成的链接丢失了gdb调试器,并且无法向我显示C++源代码.如何解决？

项目根目录是/home/.../Cpp/

./Cpp/
??? bazel-bin -> /home/picaud/.cache/bazel/_bazel_picaud...
??? bazel-Cpp -> /home/picaud/.cache/bazel/_bazel_picaud...
??? bazel-genfiles -> /home/picaud/.cache/bazel/_bazel_picaud...  
??? bazel-out -> /home/picaud/.cache/bazel/_bazel_picaud...   
??? bin
?   ??? BUILD
?   ??? main.cpp
??? MyLib
?   ??? BUILD
?   ??? ....hpp
?   ???  ...cpp
??? WORKSPACE

我有一个(基本的)C++项目:

??? bin
?   ??? BUILD
?   ??? example.cpp
??? data
?   ??? someData.txt
??? WORKSPACE

可执行example.cpp使用data/目录中的一些数据文件:

#include <fstream>
#include <iostream>

int main()
{
  std::ifstream in("data/someData.txt");

  if (!in)
  {
    std::cerr << "Can not open file!";
    return EXIT_FAILURE;
  }

  std::string message;

  if (!(in >> message))
  {
    std::cerr << "Can not read file content!";
    return EXIT_FAILURE;
  }

  std::cout << message << std::endl;

  return EXIT_SUCCESS;
}

我的Bazel设置是最小的:

• WORKSPACE:空文件
• bin/BUILD:cc_binary(name = "example",srcs = ["example.cpp"])
• data/someData.txt:包含该Hello_world! …
