如何使用bitbake构建uclibc包- Bitbake在尝试构建uclibc时引发MultipleMatches异常

Question

我正在尝试通过bitbake为arm7a架构构建uclibc，但我得到了以下输出

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

MultipleMatches

我也在尝试构建一个特定的食谱(我做错了吗？)但我得到了

user@ubuntu:~/stuff$ bitbake -b /home/user/stuff/openembedded/recipes/uclibc/uclibc_0.9.31.bb 
ERROR: Command execution failed: Traceback (most recent call last):

谢谢

Answer 1

我回答了我自己的问题，因为我在搜索这个论点时发现缺乏信息。我希望这不是不恰当的。所以..。

首先，应该在不带-b选项的情况下调用bitbake，以便计算包依赖关系

bitbake package

这样，就不需要直接构建uclibc了，因为bitbake会在必要时自动构建它(因此，您必须使用不带-b选项的bitbake )。现在还没有完成，因为对于我的Angstrom发行版(2010.x)来说，uclibc不是bitbake构建的默认库，而是eglibc构建的库。因此，您必须在stuff/build/conf/local.conf中添加一行代码：ANGSTROMLIBC = "uclibc"，可在this faq找到

最后，你可以在你的stuff/tmp/deploy/uclibc上找到所有的ipk包和源代码。
