构建 opencv 时出错：内部编译器错误：在 gt_pch_note_object 中

Question

我需要构建一个较旧的 OpenCV 版本，并且我已经坚持使用它好几天了。任何帮助表示赞赏。

我从 CMake 获得的配置：

在我使用 CMake（对于 MinGW Makefile）配置和生成之后，我尝试mingw32-make --debug在构建文件夹中进行构建。我使用的是 Windows 10 & GNU Make 4.2.1 & CMake 3.24.3 & OpenCV 2.4.11 是从https://opencv.org/releases/page/7/下载的。

我收到的错误：

老实说，这个错误并没有告诉我任何信息，我也无法在网上找到信息。构建旧版 OpenCV 的指南也很难找到。因此，正如我在开头所写的，任何帮助都非常有价值。我必须继续使用这个版本的 OpenCV。

这是您的编译器告诉您您设法遇到了内部编译器错误。“内部编译器错误”的意思正是它所说的。恭喜，我想...没有解决方法，除了手动编辑代码，猜测是什么触发了错误，并编辑 C++ 源代码以产生不同的东西，但逻辑上是等效的，并且它不会触发内部编译器错误，无论如何这是。

显示的 gcc 版本（版本 8）非常旧。尝试看看是否可以将工具链更新到更新版本的 gcc。gcc 当前版本是 13。
