请问kernel在什么位置啊?

我用redhat enterprise linux 5
请问kernel在什么位置啊? 或者用什么命令,可以查询所在位置      
kernel在boot目录下,名字一般vmlinuz-xxx
$uname -a命令可以查询kernel的详细信息      
如果想编辑内核,须先安装kernel-source包,其安装目录在/usr/src下。      
我想编译fuse-2.7.3,执行./configure之后,提示错误:
=============================
configure: error:
        *** Please specify the location of the kernel source with
        *** the '--with-kernel=SRCDIR' option
configure: error: ./configure failed for kernel
============================

然后我再执行./configure --with-kernel=/usr/scr/redhat,提示错误:
===========================
checking kernel source directory... /usr/scr/rehdat
checking kernel build directory... /usr/scr/rehdat
checking kernel source version... Not found
configure: error:
        *** Cannot determine the version of the linux kernel source. Please
        *** prepare the kernel before running this script
configure: error: ./configure failed for kernel
===========================

请问,是怎么回事啊?
