hello:
I want to rebuild my kernel without any network functions.
my step is as below:
1. type "make menuconfig" to get in kernel configuration menu.
2. disable all net functions, like[*]network support ->[]network support.
3. save the kernel configuration and I did check Makefile to sure that this configuration is used in building progress~~~

After building, I checked kernel menuconfig to see all net items I disabled resumed to enable!!! then I run the new kernel... sure, the network are all available~~~ I have no idea~
I also modified "Kconfig" in net related folders, like :
"default y(or m) -> default n"...it doesn't work!!!
do I miss something??? does any one know how to build a kernel without network??? any advice will be very appreciate!!!
thank you very much~~~

when you have the setting of the kernel you want it to stay, be sure to make clean before a usual make. I often got that some settings stay in the image from before even if I've disabled them in the config

hello:
thanks for reply, however I have done "make clean" before "make" kernel, ...it didn't work~~
do you have another ideas ?? thanks!

Actually that's the only thing I can think of why this error occurs.

Here are my steps when I create a different .config file. I usually use buildroot to generate the Image so it may differ a bit:

(1) make linux-menuconfig: save the new settings under "linux.config"
(2) make clean
(3) make menuconfig (that's buildroot): set the path to the custom linux config file (linux.config), in the kernel options.
(4) make

So I expect to get it working like this, if you don't use buildroot:

(1) in linux menuconfig save the new settings under e.g.: "linux.config"
(2) make clean
(3) in linux menuconfig load the linux.config
(4) make

If this still didn't help then maybe you have some kind of a hidden network package. (Like there is still another package about the network)

Kind regards
