linux - 如何使用 bitbake 使用 uclibc 构建包 - 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，但我得到以下输出

user@ubuntu:~/stuff$ bitbake -b uclibc
ERROR: Unable to match uclibc (19 matches found):

MultipleMatches

我也在尝试构建一个特定的食谱(我做错了吗？)，但我明白了

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

我回答我自己的问题，因为我发现搜索这个论点的信息缺乏。我希望这没有什么不妥当的。所以..

首先，应该在不使用 -b 选项的情况下调用 bitbake 来计算包依赖项

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，您必须使用不带 -b 选项的 bitbake)。此时它还没有完成，因为对于我的 Angstrom 发行版(2010.x)版本，uclibc 不是 bitbake 构建的默认库，而是构建了eglibc。因此，您必须将这一行添加到您的 stuff/build/conf/local.conf 中:ANGSTROMLIBC = "uclibc"，位于 this faq

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