邮箱进入SimGrid

Question

我正在学习simgrid中的邮箱，查看文档中的示例，但是当我试图编译这些示例时，会出现错误，主要是邮箱-> get中的错误。我会把代码片段放在下面。

if (rank == 0) {
  /* The root actor (rank 0) first sends the token then waits to receive it back */
  XBT_INFO("Host \"%u\" send 'Token' to Host \"%s\"", rank, neighbor_mailbox->get_cname());
  std::string msg = "Token";
  neighbor_mailbox->put(&msg, token_size);
  const auto* res = my_mailbox->get<std::string>();
  XBT_INFO("Host \"%u\" received \"%s\"", rank, res->c_str());
} else {
  auto* res = my_mailbox->get<std::string>();
  XBT_INFO("Host \"%u\" received \"%s\"", rank, res->c_str());
  XBT_INFO("Host \"%u\" send 'Token' to Host \"%s\"", rank, neighbor_mailbox->get_cname());
  neighbor_mailbox->put(res, token_size);
}

此错误发生在const auto =my_mailbox->getstd：：string()中；

错误:无法推断类型“auto”，也不允许输入名称

Answer 1

将auto* res = my_mailbox->get<std::string>();替换为const auto *res = static_cast<std::string*>(my_mailbox->get());
