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

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

可以使用下面的命令 modinfo module.ko 確定module的info

# modinfo hello-4.ko
license:        GPL
author:         Daniel Chen
descrīption:    A sample driver
vermagic:       2.6.35.6-45.fc14.i686 SMP mod_unload 686
   

接著# uname –r

確定kernel vermagic.

檢查/usr/src/linux/Makefile，確保下面這些特定的版本資訊與使用的內核完全一致：
VERSION = 2
PATCHLEVEL = 6
SUBLEVEL = 35
EXTRAVERSION = .6-45.fc14.i686

最後
不必完全編譯一遍內核，只得到需要的檔即可：

# make
CHK     include/linux/version.h
UPD     include/linux/version.h
SYMLINK include/asm -> include/asm-i386
SPLIT   include/linux/autoconf.h -> include/config/*
HOSTCC  scrīpts/basic/fixdep
HOSTCC  scrīpts/basic/split-include
HOSTCC  scrīpts/basic/docproc
HOSTCC  scrīpts/conmakehash
HOSTCC  scrīpts/kallsyms
CC      scrīpts/empty.o
...
     

# insmod XXX.ko 就不會出現該錯誤
