我遇到的问题是我正在尝试使用 bitbake 从头开始构建 Angstrom 图像（因为 Angstrom 现在与 Yocto 兼容）但是我在运行时遇到了错误bitbake systemd-image

我已经有一段时间了，在不同的网站上搜索。最初我尝试按照 Angstrom 网站上开发人员部分的指南进行操作，但是一旦我遇到一些错误（在我放在这里之前），我发现了 Derek Molloy 的网站http://derekmolloy.ie/building-angstrom- for-beaglebone-from-source/解决了这些错误，并为该过程提供了更多细节。
最终，我偶然发现了另一个描述我的问题的论坛帖子，但不幸的是，答案并不是很清楚（无论如何对我来说）http://comments.gmane.org/gmane.linux.distributions.angstrom.devel/7431。我不知道可能出了什么问题，而且我对 Yocto 项目还很陌生，所以我不确定是否有任何步骤丢失或我忽略了一些隐含的东西，所以我非常感谢任何能指出的人我在这个正确的方向。
作为旁注，我一直认为这可能与我拥有的 environment-angstrom-... 文件有关，因为我的是 environment-angstrom-v2013.12 并且所有其他示例都使用以前的版本，我想知道在处理这个问题时是否涉及到一个新的步骤。
