64 位雪豹上的 PyQt4

Question

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 试图访问 Qt4 类的私有成员的错误吗？有人在 Snow Leopard 上成功编译过 PyQt4 吗？

Answer 1

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/

Answer 2

在更新日志中，我昨天在专门针对 Snow Leopard 的开发快照中看到了 Phil（PyQt 的维护者）has issued fixes：

2009/09/14 12:12:49 菲尔进一步 修复了 64 位的雪豹 系统。添加 QObject.pyqtConfigure().

你使用的是昨天构建的 PyQt 吗？

This thread on the mailinglist 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（暂时）以 32 位方式重建 Qt 和 PyQt（可能还有 python）（使用-m32 编译器标志），如果您现在需要它。

Answer 3

您可能希望使用自制项目中的 PyQt：直接构建、托管依赖项。

在我的 MBP Unibody 上运行良好，全部为 64 位。
