LinuxQuestions.org - undefined reference to `__this_module' when trying to link module to kernel

Hello!

On our embedded device I have a jitter buffer module jb.o. I don't have any code for it just compiled binary jb.o. It works ok and it can be insmoded and used without the problem. Now I want it to become part of the kernel and not insmoded anymore. I tried to link it to the kernel by adding

Code:

obj-y := jb.o

to the make file. Now I get error like

Code:

arch/mips/infineon/incaip/jb/jb.a: In function `ifx_jb_get_status_proc': 

src/ifx_jb_algorithm.c:(.text+0x18e4): undefined reference to `__this_module' 

src/ifx_jb_algorithm.c:(.text+0x18e8): undefined reference to `__this_module' 

src/ifx_jb_algorithm.c:(.text+0x191c): undefined reference to `__this_module' 

src/ifx_jb_algorithm.c:(.text+0x1920): undefined reference to `__this_module' 

src/ifx_jb_algorithm.c:(.text+0x192c): undefined reference to `__this_module'

What is the cause of this? I have other modules also, which I compiled into the kernel without the problem. What is `__this_module' actually?

Regards,
