Thank you for your reply. I'm sure this will work because it makes sense since there will be only one kernel on the system. Redhat uses the "custom" tag as a precaution when recompiling kernels so that the original is left intact and one would be able to reboot in case something goes wrong with the recompiled version.
However I have found another way as well. If you include the -I flag and give the proper path to the current kernel header files, the module will be inserted. This is what I did when I booted the "custom" kernel
gcc -c hello.c -I/usr/src/linux-2.4.20-8/include
and then
insmod hello.o
I have got the directory linux-2.4.20-8 and the include directory in it has the header files for which the current "custom" kernel was compiled against. Anyways thank you for the prompt reply Brian.

*****************************************************************************************************
Go re-compile the kernel, but edit Makefile in /usr/src/linux
In the Makefile, near the top, is a line defining a name as being
"-8custom"
Change that to read ""
then make & install the kernel
After that, you'll be building kernels and modules on the same version.

Hi,
I'm relative new to linux and I've just started module programming
following the Alessandro Rubini and Jonathan Corbet "Linux Device Drivers"
book for kernel 2.4. I have got Redhat 9.0 installed on my system. I
try to use "insmod" to insert a module called hello.o, however the
system returns a message
hello.o: kernel-module version mismatch.
hello.o was compiled for kernel version 2.4.20
while this kernel is 2.4.20-8custom
In the book it is mentioned that it would be better to recompile the
kernel without the version support for modules. I believe I did the
right thing by simply changing the option of "loadable module support ->
set version information on all module symbols" from y to n. I ran "make
xconfig" and followed the steps carefully listed in the Red Hat
documentation CD plus the steps listed on Alessandro's website and as you can
see from the message I booted the recompiled custom kernel without any
problems.
I don't know if this information is pertinent as well but I typed the
following
"gcc --version" and I got
"gcc (GCC) 3.2.2.20030222 (Reh Hat Linux 3.! 2.2-5)" followed by some
text. I believe my compiler is ok. Could someone please help me out? Is
what I did the thing to do or was I suppose to do something else in
order to remove version support?
