Question

我试图在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libqt4-dev安装了sudo apt-get install libqt4-dev，并将Qt库包含在我的项目中：

/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）

正在运行qmake并创建Makefile。

但我无法建立我的项目。

这是我的代码（在默认编译器下使用make all编译并运行正常，而不是Cross ARM GCC）：

的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：

的main.cpp
mainwindow.cpp
mainwindow.h
proConfig.pro

此处 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中点击了 Build All ，我得到了：

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（如此处所述），通过运行libqt4-dev
安装了sudo apt-get install libqt4-dev

此libqt4-dev副本适用于您的主机x86 / x64 CPU。您无法使用它来交叉编译ARM CPU。

使用Cross ARM GCC编译器自己构建Qt。例如，请参阅https://forum.qt.io/topic/26540/how-can-i-cross-compile-qt-5-0。

顺便说一句，Qt 4非常老了。它将在2015年12月之后不再受支持。我强烈建议您使用Qt 5。

Qt尚未移植到此操作系统
