Kernel compilation error

Question

Hi,

I was trying to compile the Linux kernel.

I am getting the following error:-

"No rule to make target arch/x86/kernel/entry_32.o', needed by arch/x86/kernel/built-in.o'."

Before this I configured the kernel(didn't do anything extra except the default options). configured the kernel using "make gconfig". The config was generated. I am using x86 32 bit machine (Fedora 9) kernel version 2.6.30.

Finally I used :- "make bzImage" to compile.

Tried to search the net for a solution but without success. How to fix these errors?? Kindly help.

Thanks,

Sourabh

Answer 1

You need to call make before make bzImage.

make clean or make mrproper would perhaps help too depending how much you screwed up already.

Answer 2

I agree with the previous answer, you should take a look at how to compile a kernel, the fedora way (here). Not sure this is still up-to-date, but leveraging the provided tools is a good idea sometimes.

Answer 3

Maybe you didn't actually configure the kernel. Did you use any of "make config", "make menuconfig", "make xconfig"?

Are you running an x86 distribution or an x86_64 one? In the latter case, you need the x86 32 bits compilation environment too.

Advice : this is a poorly asked question. You didn't give any relevant information : Linux distribution and architecture, kernel version you want to compile, the commands you tried and the messages you got.
