系统：WIN7 Home Basic
安装：qt-win-opensource-4.7.3-mingw + Dev-C++ 4.9.9.2
1、QT软件安装正常，但编译Debug库有如下错误提示：
dialogs\qprintdialog_win.cpp: In function `void qt_win_read_back_PRINTDLGEX(PRIN
TDLGEX*, QPrintDialog*, QPrintDialogPrivate*)':
dialogs\qprintdialog_win.cpp:159: error: `PD_CURRENTPAGE' undeclared (first use
this function)
dialogs\qprintdialog_win.cpp:159: error: (Each undeclared identifier is reported
only once for each function it appears in.)
mingw32-make[2]: *** [tmp/obj/debug_shared/qprintdialog_win.o] Error 1
mingw32-make[2]: Leaving directory `G:/Qt/4.7.3/src/gui'

mingw32-make[1]: Leaving directory `G:/Qt/4.7.3/src/gui'
mingw32-make: *** [sub-gui-sub_Debug] Error 2
2、WIN7下编写了个QT GUI小程序，命令行下执行提示“***.exe已停止工作...”如下：
