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?
Mir
