Unhappy Unable to insert lodable module


Hi,

I am facing problem while inserting loadable module on FC5 kernel 2.6.15.1_2054FC5. I am able to get files named "hello.o" & "hello.ko" after compiling module "hello.c". Folowing is the error message I am getting:

insmod: error inserting './hello.ko': -1 Invalid module format

After insmod I used dmesg command & this is what it gave:

hello: disagrees about version of symbol struct_module

Please someone help me to rectify this problem as early as possible.

Thanks in advance.

In order to have kernel source code I downloaded kernel-2.6.15.1.2054_FC5.src.rpm from http://download.fedora.redhat.com/. After that installed the kernel source using following commands:

rpm -ivh kernel-2.6.15.1.2054_FC5.src.rpm

Then I navigated to /usr/src/redhat/SPECS/

rpmbuild –bp –target `uname -p`kernel –2.6.specs

Created Symbolic link to kernel source directory

ln –s /usr/src/redhat/BUILD/kernel-2.6.15/linux-2.6.15/ /usr/src/linux

Finally I executed these commands at /usr/src/linux/:

1.make
2.make modules
3.make modules_install

Now I wrote simple module & while trying to insert it faced the problem.

Please reply if anyone knows the solution.
