问题描述
我正在尝试使用在http://cgit.openembedded.org/meta-openembedded/tree/meta-oe/recipes-support/opencv上找到的opencv_4.4.0.bb配方将OpenCV 4.4.0包含在我的Yocto构建中 我的Yocto版本是2.2.0（Morty）。
构建opencv_3.4.3时没有任何问题。但是，使用bitbake构建4.4.0时遇到错误：
bitbake opencv。
这是错误日志的一部分：

我试图在线搜索这些错误，但是找不到类似的东西。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这些问题吗？
