[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.

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);
}
