Question

我正在尝试在QT应用程序中使用QGLWidget，并且我已将“QT + = opengl”行添加到.pro文件中，但我现在正在获取:: error：collect2：ld返回1退出状态当我尝试编译我的程序时

编译输出显示以下内容，

Running build steps for project MapEditor...

进程“C：/Qt/2010.05/mingw/bin/mingw32-make.exe”退出，代码为％2。构建项目MapEditor时出错（目标：桌面）执行构建步骤'Make'时

和我的.pro文件包含以下内容，

TARGET = MapEditor
TEMPLATE =app

QT += opengl

SOURCES += \
    Main.cpp \
    window.cpp \
    glwidget.cpp

HEADERS += \
    window.h \
    glwidget.h

Answer 1

看起来有些文件丢失了。你有没有把它添加到标题中？

 #include <QtOpenGL>

Answer 2

检查.pro文件（即项目文件），你已经在SOURCES和HEADERS标签中添加了所有类文件和头文件。[为此目的，从build menubar options运行qmake命令] 还要检查你是否在glwidget类的开头声明了Q_OBJECT宏。

:: error：collect2：ld使用QT和opengl返回1退出状态
