虽然许多帖子说，STL库通常不适用于arduino/embedded系统，但它们似乎安装在我的Arduino编译器上！还有很多工作。

问题：(所示完整草图)

代码语言：javascript
运行
复制
std::vector<int> foo;         // this works fine
std::map<int,int> bar;    // adding this gives an error

void setup() {}
void loop() {}


sketch_jun05a:4:1: error: 'map' in namespace 'std' does not name a type
 std::map<int,int> bar;
 ^

所以我不知道为什么std：：会起作用，但是std::map不起作用。

编译平台:目标: Ardunio.app 1.8.12 : ESP8266

下面粘贴了详细的错误消息。

分析：

我在我的arduino应用程序中搜索map.h，我找到了一个看起来很广泛的STL库类，包括stl_map.h。

它们位于我的系统中，位于这条路径上：

代码语言：javascript
运行
复制
~/Library/Arduino15/packages//esp8266/tools/xtensa-lx106-elf-gcc/2.5.0-4-b40a506/xtensa-lx106-elf/include/c++/4.8.2

and most of the interesting looking headers are in a subdir called "bits".

另一件奇怪的事情是，std::vector不包含任何头文件就能工作。这对我来说是意外的。

我没有配置我的搜索路径，也没有设置任何环境变量，所以无论Arduino应用程序安装了什么，都是它正在搜索的路径。

我也找不到关于这个的任何文档.

我发现的每一件事都表明，Arduino/isn 8266没有STL！我确实找到了一些名为ArduinoSTL和avr_stl的gitbub项目库，之前我确实将它们安装为本地用户库(不是在系统库中)，但我并没有在上面的草图中导入这些库。

以下是完整的错误消息：

也许这能帮到一个人：

您可以在这里为Arduino IDE找到一个(非常老的) STL端口：https://github.com/maniacbug/StandardCplusplus

测试后注意：好，好，好.那个特别的库是错误的(有着令人讨厌的逐个错误！)尤其是在我不想重新发明的课程中)。

神秘的是，矢量被esp8266核心包含在其他地方，而map却没有。幸运的是，显式包含map使我的编译器很高兴。Arduino IDE 1.8.13，esp8266内核3.02，windows 7 32位.

对于其他STL模板也是如此，如std::string，#include

std::vector<int> foo;       // vector 'mysteriously' included elsewhere by esp8266 core
// As suggested by compiler along with 'map' error if map not user included:
//  "note: 'std::map' is defined in header '<map>'; did you forget to '#include <map>'?"
#include <map>              // user must include to use std::map (see above comment)
std::map<int, int> bar;
