使用 mingw32-make 编译 qt-webkit 以进行二分

Question

我启动了一个 bisect qtwebkit，当我尝试在第一阶段编译它时，它给了我以下异常。我尝试使用较旧的 qmake，但仍然给出相同的异常。这到底是什么意思，我该如何解决。

Answer 1

恕我直言。 2,3很重要：

错误“此文件是使用 4.8.0 的 moc 生成的。它”

错误“不能与此版本 Qt 中的包含文件一起使用。”

您的版本低于 qt 4.8，并且您所有的 moc 文件都是在 moc v4.8 的先前版本中生成的。您必须清理构建目录并重新启动构建命令（确保使用正确版本的 qmake、moc 等）。
