GCC问题

knuoxy

安装GCC3.4的听人说如果本身系统没有GCC是不允许安装高级版本的
/configure --prefix=/root/gcc
the command 'cc -o conftest -g conftest,c'failed
you must set the envivonment variable cc to a working complier
gcc296 -v
查看到版本了是296的

rpm -qa |grep gcc

compat -9cc-c++ -7.3-2.96.118

之后朋友告诉我已经安装了让我查下GCC在什么目录下
[root@xiaoye root]# which gcc
/usr/bin/which: no gcc in (/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/
usr/bin:/usr/X11R6/bin:/root/bin)
请大家帮忙我该如何办呀

RedHat 7.x 内的 "gcc-2.96" 可以说是 RedHat 最失败，最为人诟病之作，当时 gcc 开发团队并没有此编译器，是 RedHat 自己把 2.95.x 打了很多补丁後硬灌的名字，结果得出来的 "gcc-2.96" 无比buggy，很多东西无法正常编译又或者不能歉容於其他正常用 2.95.x 编译出来的系统，早期内核文件均呼吁用户不要用 "gcc-2.96" 来编译，必定有问题的！这也是当年我下定决心舍弃 RedHat 的主要理由！

死心吧！用 gcc-2.96 编译 gcc-3.4 估计不能 bootstrap，再者 RH7.3 也太陈旧了，兄弟早日把系统升级为上，若兄弟仍希望用 RH 产品，那就转 FC 系列好了。
