Why is `fdb_future_block_until_ready` blocking forever?

I’m on 7.1.27, and fdb_future_block_until_ready is blocking forever while I’ve started the network.

This is all of my source code:

#define FDB_API_VERSION 710
#include <foundationdb/fdb_c.h>
#include <pthread.h>
#include <stdio.h>
#include <stdlib.h>

void check_fdb_err(int err) {
  if (err != 0) {
    fprintf(stderr, fdb_get_error(err));
    exit(1);
  }
}

pthread_t network_thread_id;

void *run_network() {
  check_fdb_err(fdb_run_network());
  return NULL;
}

int main() {
  check_fdb_err(fdb_select_api_version(710));
  fdb_setup_network();
  if (pthread_create(&network_thread_id, NULL, (void *)run_network, NULL) !=
      0) {
    fprintf(stderr, "Failed to create pthread.\n");
    exit(1);
  }

  FDBDatabase *database;
  check_fdb_err(fdb_create_database(NULL, &database));

  FDBTransaction *transaction;
  check_fdb_err(fdb_database_create_transaction(database, &transaction));

  FDBFuture *future = fdb_transaction_get(transaction, "somekey", 1, 0);

  check_fdb_err(fdb_future_block_until_ready(future));

  fdb_transaction_destroy(transaction);
  fdb_database_destroy(database);

  check_fdb_err(fdb_stop_network());
}

Never mind. I replaced the lib and include headers from the RPM package with those in the DEB package and it worked.
