Hello. I compiled a simple module that I have copied from the on-line book "The Linux Kernel Module Programming Guide" at http://www.tldp.org/LDP/lkmpg/2.6/html/ but I am not able to load it with 'insmod'. It returns the following error: [root@localhost modules]# insmod hello-2.ko insmod: error inserting 'hello-2.ko': -1 Invalid module format I've searched Google but I don't find any solution. This is the module source: #include <linux/module.h> /* Needed by all modules */ #include <linux/kernel.h> /* Needed for KERN_ALERT */ #include <linux/init.h> /* Needed for the macros */ static int __init hello_2_init(void) { printk(KERN_ALERT "Hello, world 2\n"); return 0; } static void __exit hello_2_exit(void) { printk(KERN_ALERT "Goodbye, world 2\n"); } module_init(hello_2_init); module_exit(hello_2_exit); The Makefile is (I've compiled with only typing "make"): KDIR:=/lib/modules/$(shell uname -r)/build obj-m += hello-1.o obj-m += hello-2.o obj-m += hello-3.o default: $(MAKE) -C $(KDIR) SUBDIRS=$(PWD) modules clean: $(RM) .*.cmd *.mod.c *.o *.ko -r .tmp* Can any of you help me, please? What am I missing? Thank you all in advance, fabio -- Kernelnewbies: Help each other learn about the Linux kernel. Archive: http://mail.nl.linux.org/kernelnewbies/ FAQ: http://kernelnewbies.org/faq/
