I get these warnings when I compile the latest kernel. A few of them I know how to fix but what should I do with them I dont know how to fix? is it important not to get any warnings when compiling a kernel?

Most likely you selected options that depend on other supported items in the kernel. Either disable those in the errors entirely or find out what else they need for each to be enabled in the kernel.

Though the kernel is not SUPPOSED to spit out warnings, it can. Warnings are generally ok, unless you see bugs/crashes after booting the kernel. Some odd behaviors used in optimization can generate warnings, in fact.

I´ve read that "kernel/intermodule.c:178: warning:" comes when you chose the 386 processor. I picked the P4-based one(MPENTIUM4)becouse I have a Compaq 500 Mhz Celeron, did I chose wrong?

Thanks for helping out guys!

If you have a 500 MHz Celeron, you definitely do not have a P4-based Celeron.

I've reduced the number of errors, but the ones thats left are a bit annying. Any ideas where I did wrong? well here they are:

I wouldn't worry about any of these warnings, particularly the "unused variable" and deprecated warnings. Exactly which kernel version are you compiling? It's not a -rc*, is it?

No, it's 2.6.14.4. thanks for taking your time to help me out Matir. You saved me alot of time!

It's no problem, I'm just glad I'm able to help. So long as the build finishes and exits normally, you should have a fully functional kernel ready to go.
