linux – 加载内核模块时的未知符号

我需要帮助,了解为什么我插入模块时出错.我试过 this没有成功.

$sudo modprobe lpfc_scst 
FATAL: Error inserting lpfc_scst (/lib/modules/2.6.32-33-generic/extra/lpfc_scst.ko): Unknown symbol in module,or unknown parameter (see dmesg)

非常感谢.

解决方法

>编辑scst.
>将生成的Module.symvers附加到/lib/modules/u0026lt;versionu0026gt;/build/Module.symvers(Hack.不知道为什么内核没有看到导出的符号).
>将scst复制到/ lib / modules /< version> / extra.
> depmod -a.
>编译lpfc_scst.
>插入模块lpfc_scst没有问题.

祝你今天愉快.
