Hi Stefan,
maybe your sources are linked to the headers ? This is my way, it might not be
correct, but it works:
Go to /usr/src
Check a link "/usr/src/linux" , it should point to the unpacked
linux-sources, "/usr/src/linux-source-2.6.20"
If the link points to the headers, delete it and make it new, pointing to the
sources.
O.k., now cd into /usr/src/linux
Do "make menuconfig"
In the forth line of the GUI you see "Processor type and features". Step into.
In the second line of this menu, you see "Processor family" , anbd here you
can choose your processor.
Hint: The kernel-headers are only for building modules, the kernel-sources are
building a kernel.
I hope, this helps. Good luck !
Regards
Hans
