gcc，g++ 编译的区别

test.cpp
int main()
{
return 1;
}

1.gcc 编译报错
gcc test.cpp
/tmp/ccgGC04E.o:(.eh_frame+0x12): undefined reference to `__gxx_personality_v0'
collect2: ld returned 1 exit status

2.g++编译通过
g++ test.cpp

3.改扩展名(test.c)后gcc可以编译通过
gcc test.c

4.添加链接库(lstdc++)后，gcc可以编译通过

gcc -lstdc++ test.cpp
