编译时出现错误:找不到'QtGui/QAction'文件#include< QtGui/QAction> [英] When compiling get error: 'QtGui/QAction' file not found #include <QtGui/QAction>

问题描述

我刚刚安装了Mac OS X 10.8.3和Qt Creator 3，XCode和XCode命令行工具.我正在尝试编译可在另一台计算机上使用的项目，但是每次我去全部构建"时，都会得到error: 'QtGui/QAction' file not found 在#include <QtGui/QAction>

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 found in #include <QtGui/QAction>

我尝试在.pro文件中添加第二行和第三行，但没有帮助

I tried adding the second and third line in the .pro file but it didn't help

QT       += core gui opengl
CONFIG += qt
QT += gui
TARGET = BasicOpenGL
TEMPLATE = app

更新:我也尝试了此.pro文件，但该文件不起作用

UPDATE: I also tried this .pro file and it didn't work

QT       += core gui opengl
QT += widgets
TARGET = BasicOpenGL
TEMPLATE = app

我应该说这是我第一次尝试在Mac上进行开发.

I should say this is my first time attempting development on mac.

编译来自Qt的输出

Versions/A/Headers -I/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk/System/Library/Frameworks/AGL.framework/Headers -I. -I. -F/Users/john/Qt/5.2.0/clang_64/lib -o mainwindow.o ../Framework/mainwindow.cpp

15:51:32: The process "/usr/bin/make" exited with code 2.
Error while building/deploying project BasicOpenGL (kit: Desktop Qt 5.2.0 clang 64bit)

更新:我可以使用它，但是在拧紧所有螺丝钉的情况下，我不确定该怎么做.我以全新的Mac映像开始，安装了系统更新，安装了xcode，安装了xcode命令行工具，安装了QT Creator 3.0，安装了QT库4.8.1，并在QT Creator中设置了编译器.

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.

推荐答案

在Qt5中，QAction标头在QtWidgets include子目录中，而不是在QtGui中(对于Qt4而言是正确的).尽管实际上不需要指定include子目录，因为qmake将为您处理.您只需将QT += widgets添加到您的.pro文件中.

In Qt5, QAction header is in QtWidgets include sub-directory, not in QtGui (that's true for Qt4). Though you don't actually need to specify include sub-directories since qmake will handle that for you. You just need to add QT += widgets to your .pro file.
