安装一个GCC编译器不好用

[oyxiaoyu0]

写个hello world的程序。


原来我安装一个GCC，版本可能不好，编译后报错误
$ gcc test.c
/usr/lib/dld.sl: Can't open shared library: /usr/local/lib/libiconv.sl
/usr/lib/dld.sl: No such file or directory
Abort(coredump)
后来换了个版本，还是报错误。错误信息换别的了
$ gcc test.c
as: warning 2: Unknown option "--traditional-format" ignored.
as: "/var/tmp//cc5KIeLg.s", line 21: error 1052: Directive name not recognized - NSUBSPA
$ which gcc
/usr/local/bin/gcc

请问各位大侠这是怎么回事呢
