如何构建旧版本的 gcc？

Question

我在 Ubuntu 14.04.2 32 位平台上，我安装了 gcc 4.8.4。我想构建旧版本的 gcc (2.95.3) 来编译旧版本的 linux 内核。我试图遵循这个gcc-2.95.3和这个gcc-2.95.3-64（虽然后者指示如何在 64 位主机上构建 32 位的 gcc，它似乎有帮助但没有工作）指南，但我没有建立它。有没有办法在我当前的发行版中编译它？

编辑：这是我使用的错误消息./configure --prefix=/usr/local/gcc --sysconfdir=/etc ，make bootstrap如果我不使用引导标志，我会在达到以下错误之前收到更多错误。以下错误消息来自gcc-2.95.1

您将很难在现代系统上构建这样一个旧版本的 gcc……您复制的错误来自texinfo，它不再与 gcc 2.95 中包含的文档兼容。

您可以尝试直接从http://snapshot.debian.org/package/gcc-2.95/2.95.4.ds15-27/安装二进制文件；安装cpp-2.95并gcc-2.95从那里为您提供 C 支持，而无需触及您现有的 gcc 安装。要获得您需要的 C++ 支持g++-2.95和库；我还没有检查它们在现代系统上的安装情况。
