I'm using Ubuntu 12.10 installed alongside Windows and the default loader is GRUB.

I've downloaded kernel 3.8.5 tar.xz file and want to install without erasing the existing 3.5 kernel.

Following the instructions given in the README file it said ncurses library is required.

I extracted the file and did the following. The terminal output is shown below.

root@Ubuntu:/home/prasanna/linux-3.8.5# make O=/home/name/build/kernel menuconfig

  HOSTCC  scripts/basic/fixdep

  GEN     /home/name/build/kernel/Makefile

  HOSTCC  scripts/kconfig/conf.o

 *** Unable to find the ncurses libraries or the

 *** required header files.

 *** 'make menuconfig' requires the ncurses libraries.

 *** 

 *** Install ncurses (ncurses-devel) and try again.

 *** 

make[2]: *** [scripts/kconfig/dochecklxdialog] Error 1

make[1]: *** [menuconfig] Error 2

make: *** [sub-make] Error 2



After installing ncurses, I ran the command menuconfig a dialogue box appeared and coundn't proceed much. I tried with "config" selecting default optioins.



     make O=/home/name/build/kernel

     sudo make O=/home/name/build/kernel modules_install install

When I entered the first command of above got error and it read: run "make mproper". And this command said no configuration file.
I'm truly not understanding what's happening.

Please help me out suggesting any other easy way to install the same tar.xz file of Linux kernel with default options without erasing the older one so that I get choices of kernel at boot up.
