安装GCC遇到的问题

shamao

刚刚装好REDHAT LINUX 9,接着想装编译的东西,听说GCC是最常用的.
但是遇到的问题是:
this configuration is not supported in the following subdirectories:
target-libf2c target-libobjc
(any other directories should still work fine.)
../gcc-3.4.0/configure:line 2332: cc: command not found.
***the command 'cc -o conftest -g conftest.c' failed.
***you must set the environment variable CC to a working compiler.
请问我该怎么做呀?CC是什么意思啊?
