no symbol version for module_layout

SLES 解决module: no symbol version for module_layout 方法

问题：

在SLES中/usr/src/linux-3.0.13-0.27-obj/x86_64/default/目录下 make XX.ko， 拷贝ko到相应目录，然后modprobe XX

出现：module: no symbol version for module_layout

根本原因：Unknown

解决方法：

两步：

1.确保/usr/src/linux-obj/x86_64/default/Modules.symvers文件是完整的，

如果以前在/usr/src/linux-3.0.13-0.27-obj/x86_64/default/目录下 make XX.ko 的话，该文件会重新生成这个模块所导出的符号。

所以要检查一个这个文件，如果很多行，那就对了。

 如果很少，就说明被覆盖了，需要重新安装kernel-default-devel rpm包。

Vsles11sp1 /mnt/Work/NOVELL/Product/SLES-11-SP1 #rpm -ivh kernel-default-devel-2.6.32.12-0.7.1.x86_64.rpm --force
Preparing... ########################################### [100%]

可在/usr/src/linux-2.6.32.12-0.7-obj/x86_64/default/看到Modules.symvers 文件

2. 编译模块的方法：

又一例： 在内核原目录中去编译。
