readline.c:

#include <stdio.h>
#include <readline/readline.h>
#include <readline/history.h>

int main(int argc, char *argv[]){
    readline("console>>");
    return 0;
}

一开始编译没有-lreadline，结果出现undefined reference to 'readline'。

但加上了以后还是报错：

/usr/lib/gcc/x86_64-redhat-linux/4.1.2/../../../../lib64/libreadline.so: undefined reference to `PC'

到底怎样才能顺利编译readline?
