configure and build the kernel 4.9
 

Hello All,

I am following README that comes with package.I run following command to configure and build
make O=/home/name/build/kernel menuconfig

I didnt changed any parameter and went for default settings.After running following command
make O=/home/name/build/kernel

I got this issue:
make[1]: Entering directory `/home/rahul/build/kernel'
arch/x86/Makefile:140: CONFIG_X86_X32 enabled but no binutils support

I installed binutils:
binutils 2.24-5ubuntu14.1
binutils-aarch64-linux-gnu 2.24-5ubuntu14cross0.11.2
binutils-arm-linux-gnueabi 2.24-5ubuntu13cross1.97.1

GCC compiler version is:gcc (Ubuntu 4.8.4-2ubuntu1~14.04.3) 4.8.4

You have some kernel flags set which do not match your system. You need to use the menuconfig stage of the build to unset these two flags before building.

When you are in menuconfig, enter a / and then type the name of the flag you wish to change.
You will be taken automatically to the right part of the menu. Unset both flags, then try make again.

Hello Hazel,

I tried but it simply gives "No matches found".

one more input i want to compile linux 4.9 and i am having following version
linux 3.19.0-25-generic #26~14.04.1-Ubuntu SMP Fri Jul 24 21:16:20 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Is it due to version i am getting issue??

That's strange! I just tried it out with 4.7.9 kernel source and found both flags without difficulty. The search isn't even case-sensitive.

The X86_X32 flag is in the "Executable file formats" section. The other one comes under "General setup".
