我正在尝试构建 Yocto 映像，但编译 glibc 时构建失败。
如果我只跑
bitbake glibc -c compile
我收到编译错误如下：

glibc库显然非常重要，那么我该如何解决编译错误呢？
获取包裹。
MACHINE=at91sam9rlek bitbake glibc
Clean
MACHINE=at91sam9rlek bitbake -c clean glibc
编译菜谱
MACHINE=at91sam9rlek bitbake -f -c compile glibc
您还可以指定MACHINE定义。正如我所见，你使用meta-atmel。您可以设置MACHINE根据您的董事会的定义。
Note: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。
