Dear Sir,
I eventually know what the problem is. I overlook this line at the end of the Makefile
strip program
So I can't find any symbols from the object file when I gdb it. Everything is OK when I delete this line from the Makefile.
Thank you for so much hints from you.

>> gcc -c program_2.c -g -Wall
>> gcc program.o program_1.o program_2.o -o program -g -Wall
>>

>> Function "main" not defined.
