QtCreator：如何编译外部源文件 [英] QtCreator: How to compile external source files

问题描述

我有我的C ++项目文件，并想为这些源文件创建一个额外的图形用户界面。我使用Windows，MVSC2012和Qt 5.1.1与Qt Creator 2.8.1。

I have my C++ project files and want to create an additional graphical user interface for these sourcefiles. I am using windows, MVSC2012 and Qt 5.1.1 with Qt Creator 2.8.1.

所以这里是我有：

我的QtCreator项目文件夹，包括以下自动生成的文件

My QtCreator project folder, including the following auto-generated files

c:/creatorProject/creatorProject/main.cpp
c:/creatorProject/creatorProject/mainwindow.cpp
c:/creatorProject/creatorProject/mainwindow.h
c:/creatorProject/creatorProject/mainwindow.ui
c:/creatorProject/creatorProject/creatorProject.pro
c:/creatorProject/creatorProject/creatorProject.pro.user

源文件与逻辑在一个单独的文件夹，例如

Furthermore I the source files with the "logic" in a separated folder, e.g.

c:/programLogic/myFunctions.h
c:/programLogic/myFunctions.cpp

所以我只想添加这些文件到我的QtCreator项目，可以例如包含myFunctions.h并使用它。

So I simply want to add these files to my QtCreator project so that I can e.g. include "myFunctions.h" and work with it.

我的尝试：我使用Qt Creator并添加了 myFunctions.h <通过使用creatorProject >>右键单击>>添加现有文件..分别在 myFunctions.cpp 之后，我的creatorProject.pro看起来像这样：

My attempt: I used Qt Creator and added myFunctions.h respectively myFunctions.cpp by using "creatorProject >> right click >> add existing file..". After doing that my creatorProject.pro looks like this:

[...]
SOURCES += main.cpp\
        mainwindow.cpp \
    ../../programLogic/myFunctions.cpp

HEADERS  += mainwindow.h \
    ../../programLogic/myFunctions.h

看起来完全正常。 Qt Creator甚至在项目浏览器中显示这些文件！但是我有麻烦使用myFunctions.h在mainwindow.cpp。

Looks totally fine for me. Qt Creator even shows these files within the project explorer! However I have trouble using myFunctions.h within mainwindow.cpp.

#include "myFunctions.h" // Include can not be found
#include "../../programLogic/myFunctions.h" // Include is found but I get linker errors since myFunctions.cpp is not compiled?!

我的设置有什么问题？

推荐答案

您还需要在 .pro 文件中添加 INCLUDEPATH

You need to add the INCLUDEPATH also in your .pro file.

如下：

INCLUDEPATH += "C:/programLogic"
