When compiling get error: 'QtGui/QAction' file not found #include <QtGui/QAction>
提问by Celeritas
I just installed Mac OS X 10.8.3 and Qt Creator 3, XCode, and XCode command line tools. I'm trying to compile a project that works on another computer but each time I go to "build all" I get error: 'QtGui/QAction' file not foundin #include <QtGui/QAction>
我刚刚安装了 Mac OS X 10.8.3 和 Qt Creator 3、XCode 和 XCode 命令行工具。我正在尝试编译一个可以在另一台计算机上运行的项目，但每次我去“全部构建”时，我都会error: 'QtGui/QAction' file not found进入#include <QtGui/QAction>
I tried adding the second and third line in the .pro file but it didn't help
我尝试在 .pro 文件中添加第二行和第三行，但没有帮助
QT += core gui opengl
CONFIG += qt
QT += gui
TARGET = BasicOpenGL
TEMPLATE = app
UPDATE: I also tried this .pro file and it didn't work
更新：我也试过这个 .pro 文件，但没有用
QT += core gui opengl
QT += widgets
TARGET = BasicOpenGL
TEMPLATE = app
I should say this is my first time attempting development on mac.
我应该说这是我第一次尝试在 mac 上开发。

When executing step 'Make'
UPDATE: I got it to work but with all the screwing around I'm not exactly sure what did it. I started with a fresh mac image, installed system updates, installed xcode, installed xcode command line tools, installed QT Creator 3.0, installed QT libraries 4.8.1, setup the compilers in QT Creator.
更新：我让它工作了，但由于所有的问题，我不确定它做了什么。我从一个新的 mac 镜像开始，安装系统更新，安装 xcode，安装 xcode 命令行工具，安装 QT Creator 3.0，安装 QT 库 4.8.1，在 QT Creator 中设置编译器。

Try doing a make cleanfollowed by a make. I had this exact problem on a Windows 7 system, and this is what worked for me.
尝试执行 amake clean后跟 a make。我在 Windows 7 系统上遇到了这个确切的问题，这对我有用。

In Qt5, QActionheader is in QtWidgetsinclude sub-directory, not in QtGui(that's true for Qt4). Though you don't actually need to specify include sub-directories since qmakewill handle that for you. You just need to add QT += widgetsto your .profile.
在 Qt5 中，QAction头文件在QtWidgetsinclude 子目录中，而不是在QtGui（对于 Qt4 来说是这样）。尽管您实际上并不需要指定包含子目录，因为它qmake会为您处理。您只需要添加QT += widgets到您的.pro文件中。

Set the version to Qt5, change all #include<QtQui/*>s into #include<QtWidgets/*>.
And add QT += widgetsin your .pro file.
Rebuild the project, when you get the error again, tap into the error message, and change the #include<QtQui/*>s into #include<QtWidgets/*>too.
设置版本为Qt5，将#include<QtQui/*>s全部改成#include<QtWidgets/*>. 并添加QT += widgets您的 .pro 文件。重建项目，当你再次出现错误时，点击错误信息，将#include<QtQui/*>s也改成#include<QtWidgets/*>。
