以“StandardCplusplus”中的Arduino库问题 [英] Issues with 'StandardCplusplus' Library in Arduino
问题描述
我不得不写一些code为Arduino的在C ++中。在code完美的作品，但我用了像载体，ifstream的，等一些库中的Arduino是行不通的。
I had to write some code for Arduino in C++. The code works perfectly, but wouldn't work in Arduino as I had used some libraries like vectors, ifstream, etc.
所以，我包括StandardCplusplus库。我下载了库的压缩版本。
So I included the StandardCplusplus library. I downloaded the zip version of the library.
我复制提取的版本到的Arduino的库文件夹。现在矢量库的作品，即它不给任何编译错误。
I copied the extracted version into the library folder of Arduino. Now the vector library works, i.e. it doesn't give any compile error.
但在的#include fstream的，Arduino的提供了以下错误：致命错误：unistd.h中：没有这样的文件或目录
But on #include fstream, Arduino gives the following error: fatal error: unistd.h: No such file or directory
推荐答案
一个有点晚，但也许别人遇到了同样的问题，就像我在寻找一个答案几分钟前。我通过定义符号ARDUINO（我用eclipse变成了问题，从一个错误的警告，所以我增加了项目的属性一个新的符号 - > C / C ++编译 - > 设置 - > AVR编译器 / AVR C ++编译器 - > 符号不知道你使用的是什么，但你可以添加<$ C调用AVR-G当$ C> -DARDUINO ++）。问题出在ios.cpp文件，其中有：
#IFDEF ARDUINO
＃包括LT＆;＆HardwareSerial.h GT;
＃包括LT＆;＆serstream GT;
＃其他
＃包括LT＆;＆的fstream GT;
＃万一
只要Arduino的符号在ios.cpp文件中看到，前两次包括采取的fstream的替代。
A bit late, but maybe someone else encounters the same problem, just like me looking for an answer couple of minutes ago. I turned the problem from an error to a warning by defining a symbol ARDUINO (I use eclipse, so I added a new symbol in the project's Properties --> C/C++ Build --> Settings --> AVR Compiler / AVR C++ Compiler --> Symbols. Don't know what you're using, but you could add -DARDUINO when calling avr-g++). The problem is in ios.cpp file, where you have:
#ifdef ARDUINO
#include <HardwareSerial.h>
#include <serstream>
#else
#include <fstream>
#endif
As soon as the ARDUINO symbol is seen in the ios.cpp file, two earlier includes are taken instead of the fstream.
