【问题描述】：
我正在尝试在 Eclipse 中使用 Cross ARM GCC 编译我的 c++ 项目。
我安装了GNU ARM Eclipse Plug-ins（如here 所述），通过运行sudo apt-get install libqt4-dev 安装了libqt4-dev，并将Qt 库包含到我的项目中：
/usr/include/qt4
/usr/include/qt4/Qt
/usr/include/qt4/QtCore
/usr/include/qt4/QtGui
(Project > Properties > C/C++ Build > Settings > Cross ARM C++ Compiler > Includes)
和：
QtCore
QtGui
(Project > Properties > C/C++ Build > Settings > Cross ARM C++ Linker > Libraries)
运行qmake 成功并创建Makefile。
但我无法构建我的项目。
这是我的代码（在默认编译器下使用make all 编译和运行良好，而不是Cross ARM GCC）：
main.cpp
#include "mainwindow.h"
#include <QApplication>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
MainWindow mainWindow;
mainWindow.setGeometry(0,0,mainWindow.getButtonWidth(),mainWindow.getButtonHeight()*mainWindow.getButtonsNum());
mainWindow.show();
return app.exec();
}
mainwindow.h
#ifndef MAINWINDOW_H
#define MAINWINDOW_H
#include <QMainWindow>
#include <QPushButton>
namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
Q_OBJECT
public:
explicit MainWindow(QWidget *parent = 0);
int getButtonWidth();
int getButtonHeight();
int getButtonsNum();
~MainWindow(){}
private:
QPushButton *button1, *button2, *button3, *button4;
const int ButtonWidth = 200;
const int ButtonHeight = 50;
const int ButtonsNum = 4;
};
#endif // MAINWINDOW_H
mainwindow.cpp
#include "mainwindow.h"
#include <QCoreApplication>
MainWindow::MainWindow(QWidget *parent)
: QMainWindow(parent)
{
button1 = new QPushButton("Button1", this);
button2 = new QPushButton("Button2", this);
button3 = new QPushButton("Button3", this);
button4 = new QPushButton("Button4", this);
button1->setGeometry(QRect(QPoint(0, ButtonHeight*0), QSize(ButtonWidth, ButtonHeight)));
button2->setGeometry(QRect(QPoint(0, ButtonHeight*1), QSize(ButtonWidth, ButtonHeight)));
button3->setGeometry(QRect(QPoint(0, ButtonHeight*2), QSize(ButtonWidth, ButtonHeight)));
button4->setGeometry(QRect(QPoint(0, ButtonHeight*3), QSize(ButtonWidth, ButtonHeight)));
}
int MainWindow::getButtonWidth()
{
return ButtonWidth;
}
int MainWindow::getButtonHeight()
{
return ButtonHeight;
}
int MainWindow::getButtonsNum()
{
return ButtonsNum;
}
我在./src中的文件：
- main.cpp
- 主窗口.cpp
- 主窗口.h
- proConfig.pro
这里是 proConfig.pro：
QT += core gui
greaterThan(QT_MAJOR_VERSION, 4): QT += widgets
TARGET = proConfig
TEMPLATE = app
SOURCES += main.cpp \
mainwindow.cpp
HEADERS += mainwindow.h
我在eclipse中点击Build All，我得到：
