我刚刚在 64 位的 Snow Leopard 上编译了 Qt4.6 的最新预览版，没有任何重大问题。

现在，我正在尝试使用 River Bank 网站上的最新快照对 PyQt4.6 做同样的事情。但是，编译器退出并出现以下问题：

这是 PyQt4 尝试访问 Qt4 类的私有成员的错误吗？有人在雪豹上成功编译过 PyQt4 吗？

在更新日志中，我看到 Phil（PyQt 的维护者）昨天在专门针对 Snow Leopard 的开发快照中发布了修复：

2009/09/14 12:12:49 phil 进一步修复了 64 位系统上的雪豹。添加了 QObject.pyqtConfigure()。

你在使用昨天构建的 PyQt 吗？

邮件列表上的这个线程也特别有趣。

PyQt 编译问题似乎是由 Snow Leopards 默认的 64 位编译和它附带的 64/32 位混合版本的 Python 引起的。

如果事情继续出错，我会将您的问题提交到这个邮件列表（以便他们可以得到修复 - 希望）并尝试（临时）以 32 位方式重建 Qt 和 PyQt（可能还有 python）（使用 -m32编译器标志）如果你现在需要它工作。

我刚刚让 PyQt 4.6.2 与 64 位 Python 2.6.1 一起工作。我在这里发布了说明：http: //mpastell.com/2009/11/24/pyqt-4-6-2-with-snow-leopard/

您可能想使用自制项目中的 PyQt：直接构建、托管依赖项。

在我的 MBP Unibody 上运行良好，都是 64 位的。
