linux - Yocto Morty 2.2 ld : cannot find -lgcc in glibc 2. 24-r0

Question

glibc (libgcc.a) 很好地存在于/usr/lib/路径中。我想用 sdk 和 devtools 构建一个 linux 镜像 core-image-minimal-dev。链接 glibc 时失败(到目前为止，大约 50% 的任务顺利完成)

我需要如何设置路径和库(在 local.conf 中)？找到 -lgcc 或如何正确配置？谢谢。这是错误消息:

需要任何其他输出或文件来提供帮助吗？ BR弗洛里安

您是否更改了默认的 GCC 编译器？看看这个文件:tcmode-default.inc它是设置默认编译器目标的文件。

我之前也遇到过类似的问题，就是找不到-lgcc。 Yocto Jethro: How to choose a Yocto Default Compiler? glibc failed at do_compile when use gcc 4.9
