undefined reference to `__this_module'

[rostfrei]

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

obj-y := jb.o

to the make file. Now I get error like

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?

change /usr/src/linux-2.4 to what u r using or
do a symlink of ur kernel directory to linux-2.4
or rename your kernel directory to linux-2.4

I should be more specific on the exact situation I have. I'm using Mips32 crosscompiler in the Cygwin environment. I have the Linux kernel code in the

/opt/kernel.2.4.31/source/kernel/opensource/linux-2.4.31

folder. I did what you suggested and made symbolic link in the /usr/src folder to point to the kernel directory folder

linux-2.4 -> /opt/kernel.2.4.31/source/kernel/opensource/linux-2.4.31/

The problem did not go away. I still get the same error. Can you please explain a little bit further why would such an action help in the first place?

Best regards,
