bazel build sample error #714

Closed lianghao208 closed 4 months ago

my sample code sample_server.cc from doc:

  // @note it's the users responsibility to keep the object alive
  auto registry = std::make_shared<Registry>();

  // add a new counter family to the registry (families combine values with the
  // same name, but distinct label dimensions)
  //
  // @note please follow the metric-naming best-practices:

                             .Name("observed_packets_total")

                             .Register(*registry);

    // dynamically calling Family<T>.Add() works but is slow and should be
    // avoided
    http_requests_counter.Add({{"method", method}}).Increment();

problem resolved, due to low bazel version, it works after upgrading to the newest bazel version
