gdb nexti命令未显示源代码行

Question

I set a break in main then run the program (C code) but when I nexti all that is displayed is:

0x0stuff in main ()
0x0stuff in main ()
...

Instead of :

0x0stuff       for(i=0; i < 10; i++)
8              printf("Hello, world!\n");

How can I make gdp display the source line when using nexti?

Answer 1

nexti stes through one machine instruction, not one line of source code. You want step or next for a line of source code. It is worth reading the documentation carefully to see the difference.
