我正在尝试构建 Yocto 镜像，但编译 glibc 时构建失败。
如果我只是运行
bitbake glibc -c compile
我收到如下编译错误:

glibc库显然非常重要，那么如何解决编译错误呢？
最佳答案
获取软件包。
MACHINE=at91sam9rlek bitbake glibc
干净
MACHINE=at91sam9rlek bitbake -c clean glibc
编译配方
MACHINE=at91sam9rlek bitbake -f -c compile glibc
您还可以指定MACHINE 定义。正如我所见，您使用meta-atmel。您可以根据您的主板设置MACHINE定义。
注意:确保您的 meta-atmel 版本与开放嵌入式和 yocto poky 版本匹配。这可能是根本原因。请分享结果。
