what is the proper way to make changes to udp.c?

coontie · 03-03-2004, 09:40 AM

I want to test out a few things by making some subtle changes to tcp.c and udp.c. What is the proper way of doing this? If I make changes, how do I recompile? Is there a master make file? Is there a write-up on the web about how to do this?

thank you.

According to me, a proper way would be to make a copy of your current sources. And then modify the copy. About the makefile, I suppose that your IP stack is compiled in the kernel... so you have to recompile your whole kernel: make dep && make bzImage... (don't forget to include .config file in your copy if you don't want to redo the "make menuconfig" step)

are you sure i have to recompile the entire kernel?? seems like an overkill to me...

I think, yes you have to recompile the whole kernel... but it's very "fast" (in fact if you have a 2.4 kernel with a pentium 75MHZ and 32Mo RAM, it's very long but the command to type are short

).
You just have to type (if you have thought to recopy the .config file):
make clean && make dep && make bzImage (for a 2.4 kernel)
