我是“ubuntu 社区”的新人，我刚刚和我的大学开始了一个项目，我需要安装一个工具链（OpenRisc GNU 工具链来自本教程：https://github.com/kdgwill/OR1K/wiki/OpenRisc-tools-Install），但我遇到了这个问题。
当我需要用制作命令 （构建 GCC - 第 1 阶段）该过程没有完成，并继续显示标题中报告的消息，引用了打印函数，or1k-gcc 目录中的许多文件中都存在该函数。它不会终止，只会继续运行并显示以下内容：
g++ -fno-PIE -c -DIN_GCC_FRONTEND -g -O2 -DIN_GCC-DCROSS_DIRECTORY_STRUCTURE

根据论坛或教程，我尝试更新 gcc 编译器，正如有人所说这里但什么都没有改变。
感谢所有试图帮助我的人:)
