Hi,
I am working on a larger kernel module.
This module will be based on a lot of
portable code, for which I have to implement
the OS depended code.
At the moment I can compile the complete
code into a module. Some of OS depended
code is still missing, but I do not get
any warnings from kbuild.
When I try to load the module, I can a really
strange error message:
insmod: error inserting 'foo.o': -795847932 Function not implemented
What does that mean? How can I get a list
of missing symbols?
cu, Marco

Upgrade your module tools, probably also your build procedure.

Are you creating a module for multiple platforms or migrating an
existing one to new version ?? And what do u mean by OS dependent code
??? I think it might be Architecture dependent code !!!!

Plz tell which kernel version you are using and which distribution
!!!! b/c there is a probability that you distro might have old
modutils etc ......

How do you compile the module?
I you use:
make dir/file.ko
then kbuild will warn you about undefined symbols.
Here I assume you only use standard methods in your kbuild file, and do
not play funny tricks with vermagic etc.
