linux - 如何使用带bitbake的uclibc构建软件包-Bitbake在尝试构建uclibc时引发MultipleMatches异常

我正在尝试通过bitbake为uclibc体系结构构建arm7a，但是得到以下输出

user@ubuntu:~/stuff$ bitbake -b uclibc

MultipleMatches

我也在尝试建立特定的配方（我做错了吗？），但是我得到了

谢谢

最佳答案

我回答自己的问题是因为我缺乏寻找该论点的信息。我希望这不是不合适的。所以..

首先，应在不使用bitbake选项的情况下调用-b，以便计算软件包的依赖关系

bitbake package

然后，无需直接构建uclibc，因为bitbake会在必要时自动构建它（为此，必须使用不带bitbake选项的-b）。此时，它尚未完成，因为对于我的Angstrom发行版（2010.x），uclibc不是由bitbake构建的默认库，而是由eglibc构建的。因此，您必须在stuff/build/conf/local.conf中添加以下行：ANGSTROMLIBC = "uclibc"，位于this faq

最后，您可以在stuff/tmp/deploy/uclibc中找到所有ipk软件包和源。
