/ tmp/ccM2tvqF.o: In function `main':

Thread_c.c: (.text + 0x1f): undefined reference to `pthread_create'

Thread_c.c: (.text + 0x52): undefined reference to `pthread_create'

Thread_c.c: (.text + 0x7d): undefined reference to `pthread_join'

Thread_c.c: (.text + 0xa9): undefined reference to `pthread_join'

Collect2: ld returned 1 exit status

After checking for a long time, I thought there was a problem with the code, and finally I found out that because the pthread library is not the default library of the Linux system, we need to use the library libpthread.a when connecting, so when we use pthread_create to create a thread, we should add the-lpthread parameter: gcc test_thread.c-lpthread-o test_thread. After adding this, the compilation is successful!
