在mac osx中編譯libqxt

Question

我有最新的（git）版本的libqxt。 我運行./configure並且工作得很好，然后make失敗並出現此錯誤：

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

如果重要，我正在使用OSX Mountain Lion。

謝謝！

Answer 1

好像Qxt正在使用Mountain Lion中刪除的一些私有Mac OS X API。 在以前的Mac OS X版本中沒有記錄CGSGetWindowProperty，所​​以我認為無論如何使用它都是不可靠的。

Answer 2

作為一個hacky修復你可以刪除CGSGetWindowProperty屬性調用 - Qxt將編譯，但當然QxtWindowSystem::windowTitle將無法正常工作。

為了將來參考，您可以在libqxt存儲庫中監視此問題 。
