CentOS 7 安装 gcc 4.1.2

0. 参考

在centOS7.2上编译gcc4.1.2

1. 安装了编译所需

yum groupinstall "Development Tools"
yum install wget bzip2 texinfo glibc-devel glibc-static glibc binutils vim

出现collect2: error: ld returned 1 exit status多为编译库没有安装，要安装上glibc-devel。

2.下载源码

wget http://mirrors.ustc.edu.cn/gnu/gcc/gcc-4.1.2/gcc-4.1.2.tar.bz2
tar jxvf gcc-4.1.2.tar.bz2

3. 修改代码

gcc/config/i386/linux-unwind.h

struct rt_sigframe {
    int sig;
    struct siginfo *pinfo;
    void *puc;
    struct siginfo info;
} *rt_ = context->cfa;

改为

struct rt_sigframe {
    int sig;
    siginfo_t *pinfo;
    void *puc;
    siginfo_t info;
    struct ucontext uc;
} *rt_ = context->cfa;

否则会有类似以下的编辑错误

It has a compiling error when you build gcc4.1.2:
../gcc/config/i386/linux-unwind.h:138:17: error: field 'info' has incomplete type "

4. 编译

cd gcc-4.1.2
./configure --prefix=/usr/local/gcc-4.1.2 --enable-languages=c,c++
make
make install

5. 替换现有的gcc

cd /usr/bin/
mv gcc gcc-4.8.5 #4.8.5为现版本
mv g++ g++-4.8.5 #4.8.5为现版本
ln -s /usr/local/gcc-4.1.2/bin/gcc /usr/bin/gcc
ln -s /usr/local/gcc-4.1.2/bin/g++ /usr/bin/g++

检查是gcc g++版本已经替换

gcc -v
