linux - 如何在 Redhat 7.0 中构建 gcc 4.2.0 以实现向后兼容？

Question

我必须将 gcc 4.2.0 编译为程序依赖项才能编译(Cobol 系统的向后兼容性)。我解决了一些问题，但现在抛出这样的异常:

如果我们看到此日志，我们可以发现该行为与 java lib (gcj) 依赖编译有关。我尝试使用以下设置来避免此 java 功能编译:

sudo ./configure --program-suffix=4.2.0 --without-libjava --without-gcj --disable-libgcj

但它仍在编译 GCJ 库，问题仍然发生。

我们的Linux发行版是Redhat 7.0，默认gcc是4.8.2 20140120 (Red Hat 4.3.2-16)

我会感谢您的任何帮助。

GCC-4.2.0:错误修复版本是 gcc-4.2.4 ...旧的 gcc 需要一个旧的操作系统来构建:RHEL 6 → CentOS 6.9 ...但是没有机会在 RHEL 7 上构建这些旧版本。

构建 gcc-4.2.4 :

$ tar xvf gcc-4.2.4.tar.bz2
$ mkdir build-gcc42 && cd build-gcc42/
$ export CC=gcc34 CXX=g++34 && ../gcc-4.2.4/configure --prefix=/usr/local/gcc424 --program-suffix=42 --enable-languages=c,c++ --enable-shared --enable-threads=posix --enable-__cxa_atexit -disable-checking --with-gnu-ld
$ make

软件包:gcc42-c++-4.2.4-1.el6.x86_64.rpm (14.9MB) https://drive.google.com/file/d/1eYWk6Nd63xeqqAUoJldNWRuwEGO6cAyv/view?usp=sharing → 提供/usr/bin/{ gcc42, g++42 }。

下载并安装:# cd Downloads/&& yum install ./gcc42-c++-4.2.4-1.el6.x86_64.rpm。 ...与 CentOS 7 (RHEL 7) 完美配合。

EL7 的其他旧的额外编译器是 {gcc34, g++34} https://drive.google.com/drive/folders/0B7S255p3kFXNSXBic2V4ekN0Slk?usp=sharing
