I am an amateur who just started atmega128 yesterday. I'm trying to turn on the led, but it's not working. I don't know what's wrong.  I'd really really appreciate it if you could tell me what went wrong.

You show only  the output of AVRDude, and all is ok with flashing your code to the device, Note: you can ignore the warning on the first line about sck period, your using a Chinese made USBasp, the 

firmware on these are different then the German made USBasp firmware that AVRDude is expecting.

 

So that leaves us with "not working", that is not much of an error report, I'll assume you mean your LED is not blinking, but you need to be clear about what "not working" means....

Use the code editor in the menu above the comment box when you reply with your code, it's icon looks like "<>", two places to the right of the smiley face icon, this will preserve your code and spacing when posting.

as Jim says you haven't actually said how it is "not working". also it might be an idea to show us both the code and a quick sketch/picture to show ho your have the LED connected to the 128.

 

As it is a 128 I will point out that the very first "gotcha" for most people is that brand new mega128's are really mega103's . You actually have to program something (a fuse) to say "stop being a 103 and start being a 128". If you don't do that most things will not work as expected 

 

(the alternative is to actually build the code as if it were a 103 but you probably don't want to do that!!)

This seems to confirm the M128(A) is configured correctly!  external XTAL, JTAG enabled, and 103 disabled!

Is the problem solved now? I think you'll get more responses if you share your ckt diagram too. The messages shows that your code have been successfully loaded to the microcontroller. Still, if it does not give you the desired result, then there are many things to consider. Such as, the power supply, the fuse bits of the microcontroller, circuit connections etc. What the other users have said above, should be taken into consideration too. 

 

By the way, if you ever decide to make a PCB of your project, this write-up will be helpful: https://pcbtracks.com/how-to-man...
