compile kernel problem

ufmale · 10-20-2007, 12:22 PM

I download the limux-2.6.23.1 from the kernel.org and try to compile it on my fedora 7, which has kernel "2.6.22.4-65.fc7".

I follow the step, which i am not sure i did it correctly.

First i call
1. make config
- then select all default value by just hit enter all the
way through the prompts.
2. make clean
- make[3]: warning: Clock skew detected. Your build may be incomplete.

The second step finish successfully, but the 3nd step never ends. It continue looping and show the same message as shown above. I am not sure what I did wrong, can anyone help?

Your doing old 2.4 kernel comands.
After running make config or make xconfig or make gconfig or make menuconfig you use the ' make ' command.
You can use the config file in /boot as a reference start if using say ' make xconfig ' configuration tool.

So I do this.
make xconfig
make (this builds the kernel and modules)
make modules_install (installs the modules in /lib/modules/`uname -r`
make install (install kernel image to /boot, initrd, and install to grub boot loader)

Think this is related to some file timestamps being in the future
Do make clean before make

oh and check your system time is correct

EDIT
Brian1 seems to have a better answer

Missed that one erro. Looks like the time is off on the machine. When building it looks at the time on the machine and if date is from the past then it sees compiling future code on a date that is not go and past causes an error like that.

Thank you guys. After fixed the time, it looks much better.
This is my experimental machine so I did not care about setting the time right and did not know if it would be the cause of this problem

Thanks again
