I am getting some problem in inserting a module even after compiling it for the running kernel.
[root@localhost kernel-modules]# insmod hello-1.ko
insmod: error inserting 'hello-1.ko': -1 Invalid module format
[root@localhost kernel-modules]#
This does not seem to be related with the common vermagic problem, as I see the following message in dmesg.
hello_1: disagrees about version of symbol struct_module
Please see the Makefile and make output below. Please clarify me what goes wrong.
Makefile :
obj-m += hello-1.o
all:
make -C /lib/modules/$(shell uname -r)/build M=$(PWD) EXTRA_CFLAGS="-g" modules
[root@localhost kernel-modules]# make
make -C /lib/modules/2.6.14.4-kdbnew/build M=/root/kernel-modules EXTRA_CFLAGS="-g" modules
