Dear noel,
Please follow the following steps to build the new image kernel.
You have not mentioned the kernel version here.
For 2.4.x kernel, please follow the following steps. All these steps
should perform from the kernel source directory i.e. /usr/src/linux-2.4
1. make menuconfig - we can do the
modifications here.
2. make dep - updates the
dependencies.
3. make bzImage - creates the image file under
i386 directory.
4. make modules
5. make modules_install - before executing this command
please change the EXTRAVERSION
variable in the source
directory under linux/version.h
Based on this name it
will create the modules
directory under /lib/modules...
6. make install - This will copy the System.map
and bzImage files to
/boot directory and creates
the links and finally updates
/etc/grub.conf files.
For more information please follow the following link.
