Error tip: Disagrees about VERSION of SYMBOL module_layout, workaround

Description of the problem see: http://www.ibm.com/developerworks/cn/linux/l-cn-kernelmodules/

Reference: http://www.cnblogs.com/yzwd/archive/2013/03/27/2985086.html

Machine: Ubuntu 12

Problem Description: Error when compiling module: -1 Invalid module format

by command:

DMESG

Discover the reason is actually: disagrees about version of the symbol Module_layout

Workaround:

1. First check the currently installed kernel version

Uname-r

2. Check the kernel source path specified in the makefile, and modify the correct path. Ensure that the version number is consistent.

Linux_kernel_path:=/usr/src/kernels/2.6.32-358.2.1.el6.x86_64

2.1. If there is no source code for the currently installed kernel in the/usr/src/directory, download a recompile.

2.1.1 under Ubuntu Execute command:

1 sudo apt-get install Linux-source

Execute commands under CentOS and ret hat:

1 Yum Install Kernel-devel

2.1.2 The above command is completed, the installation source code can be found in the/USR/SRC directory. For Ubuntu, because the source code is downloaded, it has to be compiled.

Execute commands in the source directory (it takes about 30 minutes to compile):

Make

3. Recompile the installation.

Cause: Makefile Set Kernel source path error, not the same as the current kernel version, resulting in version verification does not pass, unable to install.
