[root@localhost dss]# gcc -o abc abc.cpp
/tmp/ccY3hmyr.o(.eh_frame+0x11): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status
[root@localhost dss]# gcc -o abc abc.cpp -lstdc++

有两种讲法：

1. Linux Develop Notes

* 编译 c++ 程序需要添加 -lstdc++ option. sample: gcc -lstdc++ -o test test
.c，否则会报 "undefined reference to '__gxx_personality_v0' " 错误

2. 唉，用gcc命令编译C程序，用g++命令编译C++程序。

下面是abc.cpp的内容,代码确定无误.

#include <stdio.h>
#include <stdlib.h>
#include <sys/resource.h>
#include <unistd.h>

int main(int argc, char *argv[])
{
        struct rlimit rl;

        getrlimit(RLIMIT_NOFILE, &rl);
        printf("current open file limit = %1u/n", (long unsigned) rl.rlim_cur);
        printf("current open file max = %1u/n", (long unsigned) rl.rlim_max);
        rl.rlim_cur = RLIM_INFINITY;
        rl.rlim_max = RLIM_INFINITY;
        setrlimit(RLIMIT_NOFILE, &rl);
        printf("current open file limit = %1u/n", (long unsigned) rl.rlim_cur);
        printf("current open file max = %1u/n", (long unsigned) rl.rlim_max);
}
