Qt5静态链接在Ubuntu Linux上失败

Question

这是我所做的：
1.下载源
2. ./configure -static -prefix /home/user/build/qt-static/build -qt-xcb
3. make -j3
4. make install
5.构建1小时后，我做了一个简单的test.cpp：

    #include <QtGui>

    int main(int argc, char *argv[]) {
    QApplication app(argc, argv);
    QMainWindow window;
    window.resize(250, 150);
    window.setWindowTitle("Test");
    window.show();
    return app.exec();
    }

6. 创建了一个项目文件： /home/user/build/final/bin/qmake -project

    TEMPLATE = app TARGET = test INCLUDEPATH += . # missing path ? # I also tried adding CONFIG += widgets or CONFIG += static, both resulting in the same errors SOURCES += test.cpp 

7. 创建一个Makefile： /home/user/build/final/bin/qmake *pro
   Makefile的一部分：

    ############################################################################# # Makefile for building: stat # Generated by qmake (3.0) (Qt 5.7.1) # Project: stat.pro # Template: app # Command:

8. make结果出错：

    Makefile:1169: warning: overriding commands for target `stat_plugin_import.o' Makefile:808: warning: ignoring old commands for target `stat_plugin_import.o' g++ -c -pipe -O2 -std=gnu++11 -Wall -W -D_REENTRANT -fPIC -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I. -I. -I../build/final/include -I../build/final/include/QtGui -I../build/final/include/QtCore -I. -I../build/final/mkspecs/linux-g++ -o test.o test.cpp test.cpp: In function 'int main(int, char**)': test.cpp:3:22: error: variable 'QApplication app' has initializer but incomplete type QApplication app(argc, argv); ^ test.cpp:4:5: error: 'QMainWindow' was not declared in this scope QMainWindow window; ^ test.cpp:4:17: error: expected ';' before 'window' QMainWindow window; ^ test.cpp:5:5: error: 'window' was not declared in this scope window.resize(250, 150); ^ make: *** [test.o] Error 1 

9. 因此，我阅读了官方文档，并尝试了以下命令： PATH=/home/user/build/final/bin:$PATH
export PATH
qmake -config release
make
   但是我遇到了与上面相同的错误

10. 将#include <QtGui>更改为#include <QApplication>和#include <QMainWindow>将返回：

     g++ -c -pipe -O2 -std=gnu++11 -Wall -W -D_REENTRANT -fPIC -DQT_NO_DEBUG -DQT_GUI_LIB -DQT_CORE_LIB -I. -I. -I../build/final/include -I../build/final/include/QtGui -I../build/final/include/QtCore -I. -I../build/final/mkspecs/linux-g++ -o test.o test.cpp test.cpp:2:24: fatal error: QApplication: No such file or directory #include <QApplication> ^ compilation terminated. make: *** [test.o] Error 1 

预先感谢您的帮助

Answer 1

更改

#include <QtGui>

至

#include <QApplication>
#include <QMainWindow>

AlexanderXV的注释很好，因为它告诉链接器使用QtWidgets并为编译器设置正确的路径。 在Qt5中，.pro文件中的命令为：

QT += widgets

加：

您可以使用单个#include <QtWidgets> ，它包括#include <QtWidgets>所有其他头文件。
