undefined reference to `__gxx_personality_v0'

[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); }
