Qt与Firmata链接 [英] Qt Linking with Firmata

问题描述

我在Windows 7上运行Qt SDK（C ++），Firmata和Arduino Softaware

我想知道为什么firmata.h不工作

  #ifndef Firmata_Boards_h 
 #define Firmata_Boards_h 
 
 #include< inttypes.h> 
 
 #if defined（ARDUINO）&& ARDUINO> = 100 
 #includeArduino.h// for digitalRead，digitalWrite等
 #else 
 #includeWProgram.h
 #endif 
 
 
 
 
问题是当我尝试使用Qt编译它说
  D：\SGU\Semester 8\Program\OpenCVMultithreaded\Boards.h：9：错误：Arduino.h：没有这样的文件或目录
  
我们真的可以在Qt上使用firmata吗？因为在互联网我只找到Arduino软件使用公司，而不是Qt本身。
 
 
 
我试过：
  INCLUDEPATH + =D：\opencv\build\include
 INCLUDEPATH + =D：\opencv\build\include\opencv
 INCLUDEPATH + =C：\Program Files（x86）\Arduino
 INCLUDEPATH + =C：\Program Files（x86）\Arduino\hardware
 INCLUDEPATH + = C：\ Program Files（x86）\Arduino\libraries
 INCLUDEPATH + =C：\ Program Files（x86）\Arduino\libaries C：\Program Files（x86）\Arduino\hardware\arduino\cores\arduino\Arduino.h
  
但它不工作。
解决方案
这不是一个链接问题，并且与您使用的特定库无关。您可能没有指定在哪里找到头文件或库文件。
 
 
 
在您的项目文件（ .pro ）add 
  INCLUDEPATH + = PATH_TO_ARDUINNO_HEADERS 
   
 
例如 PATH_TO_ARDUINNO_HEADERS 可以是 C：/ Arduino / include  br> 
 
 
 
要指定库，您需要使用 LIBS 变量，例如
  LIBS + = Lc：/ Arduino / lib-larduinnoshared 
  
查看 qmake参考有关包含链接到外部项目的完整指南
 
 
 
 编辑： 
包含路径是要加上前缀以找到Arduino.h。 
所以如果文件位于
 C：\Program Files（x86）\Arduino\ \arduino\cores\arduino\Arduino.h
  
您需要使用
 
 
 
  INCLUDEPATH + =C：\Program Files（x86）\Arduino\hardware\arduino\cores\arduino 
  
您发布的所有其他路径对此文件无效。您将仅包含目录 的包含头文件包含在包含路径中。
 
I am running on a Windows 7 with Qt SDK(C++), Firmata, and Arduino Softaware

I was wondering why the firmata.h is not working
#ifndef Firmata_Boards_h
#define Firmata_Boards_h

#include <inttypes.h>

#if defined(ARDUINO) && ARDUINO >= 100
#include "Arduino.h"    // for digitalRead, digitalWrite, etc
#else
#include "WProgram.h"
#endif
the problem is when i try to compile using Qt it says
D:\SGU\Semester 8\Program\OpenCVMultithreaded\Boards.h:9: error: Arduino.h: No such file or directory
can we really use firmata on Qt? because in the internet I only found Arduino software using firmata, not on Qt itself.

I tried : 
INCLUDEPATH += "D:\opencv\build\include" 
INCLUDEPATH += "D:\opencv\build\include\opencv" 
INCLUDEPATH += "C:\Program Files (x86)\Arduino" 
INCLUDEPATH += "C:\Program Files (x86)\Arduino\hardware" 
INCLUDEPATH += "C:\Program Files (x86)\Arduino\lib" I
INCLUDEPATH += "C:\Program Files (x86)\Arduino\libraries" 
INCLUDEPATH += "C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino\Arduino.h" 
But it doesnt work.
解决方案
This is not a linking issue but a compilation issue, and has nothing to do with the specific library you are using. You probably haven't specified where to find the header files nor the library files.

In your project file (.pro) add 
INCLUDEPATH += PATH_TO_ARDUINNO_HEADERS
for example PATH_TO_ARDUINNO_HEADERS  can be C:/Arduino/include.


To specify libraries you need to use the LIBS variables, for example
LIBS += "-Lc:/Arduino/lib" -larduinnoshared
See the qmake reference for a complete guide on including\linking to external items

Edit: 
The include path is what is going to be prefixed to find "Arduino.h".
So if the file is at 
"C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino\Arduino.h"
you need to use 
INCLUDEPATH += "C:\Program Files (x86)\Arduino\hardware\arduino\cores\arduino"
All the other paths you posted are invalid for this file. You put only directories containing header files in the includepath.
