在mac osx中編譯libqxt

Question

我有libqxt的最新（git）版本。我跑./configure和工作得很好，然後讓失敗，此錯誤：

linking ../../lib/QxtWidgets.framework/QxtWidgets 
ld: warning: directory not found for option '-L/usr/local/pgsql/lib' 
ld: warning: directory not found for option '-L/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib' 
ld: warning: directory not found for option '-F/tmp/qt-stuff-85167/source/qt-everywhere-opensource-src-4.8.1/Desktop/Qt/4.8.1/gcc/lib' 
Undefined symbols for architecture x86_64: 
    "_CGSGetWindowProperty", referenced from: 
     QxtWindowSystem::windowTitle(long) in qxtwindowsystem_mac.o 
ld: symbol(s) not found for architecture x86_64 
collect2: ld returned 1 exit status 
make[1]: *** [../../lib/QxtWidgets.framework/QxtWidgets] Error 1 
make: *** [sub-src-widgets-install_subtargets] Error 2 

如果它的事項，我使用OSX山獅。

謝謝！

Answer 1

似乎Qxt正在使用一些在Mountain Lion中刪除的私有Mac OS X API。 CGSGetWindowProperty在以前的Mac OS X版本中沒有記錄，所以我認爲無論如何使用它都是不可靠的。

Answer 2

作爲一個hacky修復程序，您可以刪除CGSGetWindowProperty屬性調用--Qxt將編譯，但當然QxtWindowSystem::windowTitle將無法​​正常工作。
