Dear All,
?
I am building the new kernel images for the 2.6.6 and 2.6.8 kernel versions on Intel 
x86 machine which was already installed using 2.6.5-7.71 kernel version. 

I downloaded the kernel tar files from the following link. http://www.kernel.org/pub/linux/kernel/v2.6/

I build the images on the same machine for the new 2.6.6 and 2.6.8 kernels. Now I am able to boot using the new kernel images. But there is the same version.h file under all the source directories. 

I have seen the version.h file under the following source directories. 
?
1.	/usr/src/linux-2.6.5-7.71/include/linux/
2.	/usr/src/linux-2.6.6/include/linux/
3.	/usr/src/linux-2.6.8/include/linux/

The contents of the version.h file are as follows.
--------------------------------------------------
#define UTS_RELEASE "2.6.5-7.71-default"
#define LINUX_VERSION_CODE 132613
#define KERNEL_VERSION(a,b,c) (((a) << 16) + ((b) << 8) + (c))

Due the same version.h file, when I try to load the module (which was compiled using the 2.6.8 kernel image on x86 machine which was installed using 2.6.5-7.71 kernel CDs) on another machine which was installed using 2.6.8 kernel CDs, I got the following error. 

> tifm: version magic '2.6.5-7.71-default 586 REGPARM gcc-3.3' should be '2.6.8 PENTIUM4 gcc-3.2'
> insmod: error inserting 'tifm.ko': -1 Invalid module format

I understood that the bug is: we can assume that the module was compiled for 
2.6.5-7.71-default with gcc 3.3 version where as we are trying to load the module on a machine which is having 2.6.8 kernel with gcc 3.2 version. 
?
My doubt is: Why all the source directories does include the same version.h file? How can we get the different version.h files under different source directories? 
?
Please give me an idea or solution, how to resolve the problem?
?

Srinivas G
