opencv - 使用 Yocto 的 OpenCV 4.4.0 构建错误

Question

我正在尝试使用我在http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-support/opencv找到的 opencv_4.4.0.bb 配方在 我的 Yocto 构建中包含 OpenCV 4.4.0 Yocto 版本是 2.2.0 (Morty)。

构建 opencv_3.4.3 时我没有看到任何问题。但是，我在使用 bitbake 构建 4.4.0 时遇到了错误： bitbake opencv. 这是错误日志的一部分：

我试图在网上搜索这些错误，但找不到类似的东西。似乎头文件可能丢失或不是最新的，但我不确定。有人遇到过 Opencv4 的这些问题吗？
