and yes Knoppix 7.0.3 is using a more recent version of gcc 4.7.1-2 than the one used to compile
the kernel (gcc 4.7.1-1) as you read below. So I need to either downgrade gcc to 4.7.1-1 or use
a previous version of Knoppix which still uses that version of gcc. I would be nice to have installed
on Knoppix the correct version of gcc to recompile the kernel without complication. I guess this is a
suggestion for improvement that Klaus may consider to use on his next release.
Thanks for your help.
Best Regards,
Gilles

The module file can be edited manually. I have done before, after editing the module using vi, if the length of string remains, the module can be loaded. Or perhaps insmod has a force option to forcefully load a module.

Well Knoppix 7.0.2 is using an older version of gcc 4.6.3-7 so I will need to downgrade gcc on Knoppix 7.0.3.
So what is the easiest way to find and reinstall an older version of gcc ?
apt-get -y --reinstall install gcc-4.7=4.7.1 does not work: "E: Version '4.7.1' for 'gcc-4.7' was not found"

Perhaps can try this :-
# sed -i -e 's/GCC: (Debian 4.7.1-2) 4.7.1/GCC: (Debian 4.7.1-1) 4.7.0/g' oprofile.ko
Might be faster than other methods.

Nice trick but the module still does not load because of Unknown symbols.
I may have to overlay the kernel and all the modules ...

Too bad then, I think other things are probably changed too. Maybe can still try modprobe -f.

Hi kl522,
Nope: # depmod; modprobe -f oprofile ==> ERROR: could not insert 'oprofile': Exec format error
Thanks for your help !
