makefile - 为 Sparc 交叉编译编译 OpenBIOS

问题描述

我正在尝试编译从 github 存储库下载的 OpenBIOS 应用程序

git clone https://github.com/openbios/openbios.git

但是我遇到以下错误消息

grct@grct-Dell-DM061:~/openbios$ ./config/scripts/switch-arch sparc32 sparc64 amd64

我不知道如何克服这个错误？感谢我能得到的任何帮助

谢谢 ：）

Try finding and removing -Werror from the makefiles.
