Compiler error:/tmp/ccyogqyq. O :(. eh_frame + 0 × 12): Undefined reference to '_ gxx_personality_v0' col

This afternoon, I wrote a C program file named test. cpp. For the file content, see the appendix. /Tmp/ccyogqyq. O :(. eh_frame + 0x12): Undefined reference to '_ gxx_personality_v0' collect2: LD returned 1 exit status error occurs during GCC compilation. The problem of using C ++ compilation disappears. This error is caused by the filename suffix. I changed test. cpp to test. C, and then compiled it using gcc again. The specific reasons are to be further studied.
