包括opencv的Bitbake食谱 [英] Bitbake recipe that includes opencv

问题描述

我试图得到一个非常简单的食谱，使用bitbake建立，我不知道为什么opencv不能包括。所有的例子我发现使用这个设置，似乎没有问题链接到opencv。我对bitbake相当新，害怕我是误解了一些很简单的东西。感谢您提供任何帮助。

I am trying to get a very simple recipe to build using bitbake, and I cannot figure out why opencv cannot be included. All the example I have found use this setup and appear to have no problem linking against opencv. I am fairly new to bitbake, and fear I am be misunderstanding something very simple. Thanks in advance for any help you can provide.

推荐答案

尝试将depend改为DEPENDS - 大小写。

Try changing "depends" to "DEPENDS" - case matters.
