使用intel core 2 duo处理器在旧MBP上从源代码构建gcc

我试图从失败的源代码构建GCC。我正在使用的设备是旧的MacBook Pro 5,3 2009年年中型号，带有运行macOS 10.15.7 Catalina的Intel Core 2 Duo 2.66 GHz处理器

首先，我通过自制安装了GCC。然而，由于其他一些原因（见下文），我希望从源代码构建GCC。执行命令时

brew reinstall --build-from-source gcc

我收到以下错误消息

brew reinstall --build-from-source gcc

您在此处复制的输出的底部有两个建议阅读的链接：“阅读此内容：”“这些开放性问题可能也有帮助：gcc 10.3.0”您确定阅读了这些链接吗？您好，是的，谢谢您指出这一点。我已经阅读了Github和自制文档中的一些提交。然而，我对这一点不太熟悉，觉得很难。因此，我希望这里的人能帮助我找到问题，然后从源代码构建gcc。。。
