我使用的是 Ubuntu 14.04.2 32 位平台，并且安装了 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。我试着遵循这个gcc-2.95.3和这个gcc-2.95.3-64（虽然后者指导如何在 64 位主机中构建 32 位 gcc，它似乎很有帮助，但不起作用）指南，但我未能构建它。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如果我不使用引导程序标记我在达到以下错误之前遇到更多错误。以下错误信息来自gcc-2.95.1

您将很难在现代系统上构建如此旧版本的 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。
您可以尝试直接安装二进制文件http://snapshot.debian.org/package/gcc-2.95/2.95.4.ds15-27/;安装cpp-2.95并gcc-2.95从那里将为您提供 C 支持，而无需触及您现有的 gcc 安装。要获得 C++ 支持，您需要g++-2.95和库；我还没有检查它们在现代系统上的安装效果如何。

我刚刚使用以下步骤在 Ubuntu 14.04 上安装了 gcc-3.4.6 和 gcc-2.95.3教程。我在这里发布这些步骤没有多大意义，因为您还需要从该页面下载一些补丁文件。
对于这两个编译，我必须添加-D_FORTIFY_SOURCE=0到CFLAGSgcc 构建目录及其包含其他 Makefile 的子文件夹中的所有 Makefile 中。
我需要首先安装 gcc-3.4.6，然后用它来构建 gcc-2.95.3。为此，您需要CC=/opt/x86_64/gcc/gcc-3.4.6/bin/gcc在 gcc-2.95.3 的 Makefile 中进行设置。
此外，我还必须将以下文件从源目录复制glibc-2.10.1到gcc-2.95.3/glibc-workaround/教程页面上的命令创建的目录：
bits/libc-lock.hsys/param.h_G_config.h
要修复上述问题中的错误消息：我注释掉了编译或安装的 gcc-2.95.3 Makefiles 的所有部分texinfo或cpp.info.

您需要从源代码编译旧版本的 gcc，并使用前缀选项为其指定不同的目标目录。
./configure --prefix=/usr/local/gcc
我认为 gcc 配置将允许您使用现有的 /etc。
./configure --prefix=/usr/local/gcc --sysconfdir=/etc
