Hi,

I am porting some source code to powerpc platform.While compiling the kernel module i am getting following warnings. While inserting the kernel module it throws the warning as error.

WARNING: "__sync_fetch_and_add_8" undefined
WARNING: "__sync_sub_and_fetch_8" undefined

Can Anyone tell me how to resolve this issue ???

Thank you..

The kernel source, at least for the version from  SDK 1.8, does not contain the  symbols you mentioned at all. Check your header files for

their definition. If you are porting a third-party software, consult at it's vendor or maintainer.

Have a great day,
Platon
