我对 buildroot 外部工具链有疑问；最后，当我输入“ make linux-menuconfig ”命令时，我收到了以下错误（我想将此配置菜单用于 eth 驱动程序）
ubuntu@upc:~/buildroot-2021.02.5$ make linux-menuconfig

在此命令之前，我已成功完成“make”，工具链配置如下：

当我检查 arm-linux-gnueabihf 时，我收到以下输出，我已经安装了 linaro gnueabihf 工具链并将其保存为“gcc-linaro”

到时候你能指导我吗？
我想将 eth 接口添加到图像和 arm-linux-gnueabihf 外部工具链中，
我的主机是 ubuntu 18
buildroot 版本是 buildroot-2021.02.5
linaro 版本是 gcc-linaro-7.5.0-2019.12-x86_64_arm-linux-gnueabihf.tar.xz
谢谢！
