我正在使用esp8266和platformio来编写一个简单的草图。

#include <sstream>
#include <Arduino.h>

std::stringstream s;

void setup()
{
    Serial.begin(9600);
    Serial.println("Test");
}

void loop()
{

}

一切都应该正确设置，并且大多数草图都可以正常工作。但是，当我尝试使用 stringstreams 时，platformio 链接固件时会出现错误。

我对platformio和 esp 编程很陌生，但也许你们中的一些人遇到了类似的问题或从控制台日志中获得了线索。你能帮我解决这些错误吗？

据我所知，您不能轻易地包含sstream在您的项目或大多数其他 C++ 库中。

Arduino有自己的库，我建议您仔细查看String文档，因为它可能已经提供了您项目中所需的功能。

有一些用于Arduino的 C++ 库端口，包括一个StringStream端口——理论上来说——你可以使用。

也有C 库的端口，但老实说，我不知道这些库的进步/可靠性状态如何。
