C programming problem

[sujita]

I have a problem loading module,when I run the 'insmod' command,I get the message "Kernel-module version mismatch , hello.o was comoiled for 2.4.0-0.26 while this kernel version is 2.2.16-22". I use RedHat Linux 7.0 ,gcc 2.96. Please help!!!
Thanks in advance!

I assume that you have recently upgraded your kernel from 2.2 to 2.4. It could be that your system depends, to some extent, the /boot/System.map, and the System.map file being used is still from the 2.2 kernel. Copy /usr/src/kernel-source-2.4.(whatever)/System.map to /boot. This should fix your problem. -mk

------------------
If it ain't broke, fix it till it is.

Hi,
no,I did not upgrade my kernel,I just installed Red Hat 7.0 from scratch,no previously existing Linux on my pc.So what do I do?CAn I get the System.map file from any site?
I went thro the header files,came to the conclusion that 2 constants, __KERNEL__ and
__NO_VERSION__ determined the which kernel version ,so I redefined them in my pgm,with the lines, #define __KERNEL__ and #define __NO_VERSION__ and the pgm works,except that the o/p doesn't appear on the terminal and I have to check /var/log/messages for the o/p.
Thank you!

ps .. I found another solution, the -f option for insmod to 'force' loading onto a diff version..
Thanks !!
