Compile problem
Message 1 in thread
I'm trying to compile QT4.4-Win with MinGW 4.3 (alpha).
Configure works,
mingw32-make breaks on this error:

Seems the same problem described in
http://lists.trolltech.com/qt-interest/2007-04/thread00269-0.html
(1 years ago, with GCC 4.1.1 in Linux, Fedora 6)
so I don't think it's a compiler/environment problem.
I tried QT-win 4.4.0 final and QT-win 4.4.1 20 may 2008 snapshot.
Is this a bug?
Thanks
Paolo

Hi,

Indeed, qt_sendSpontaneousEvent() is not really declared anywhere, just
declared as a friend in src/corelib/kernel/qcoreapplication.h:
class Q_CORE_EXPORT QCoreApplication : public QObject
{
[...]
friend bool qt_sendSpontaneousEvent(QObject*, QEvent*);
[...]
The fix is to add in src\gui\inputmethod\qwininputcontext_win.cpp:
extern bool qt_sendSpontaneousEvent(QObject *, QEvent *);
The same fix seems to have been applied in this case:
http://lists.trolltech.com/qt-interest/2007-04/thread00269-0.html
This is a bug. Could you please send a bug report to Trolltech so that the
problem is known and a fix is scheduled?
