Dear Ezequiel,

Thank you for your response. Yes, your patch seemed to work.
Unfortunately, we cannot upgrade the package, there are too many
version specific dependencies. Currently we are getting another error
on the gcc version:

poky-hardknott-25.0.5/build/tmp/work-shared/dcbullet/kernel-source/include/linux/compiler-gcc.h:106:1:
fatal error: linux/compiler-gcc10.h: No such file or directory
|   106 | #include gcc_header(__GNUC__)
|       | ^~~~~
| compilation terminated.

There were no errors using Yocto sumo which used gcc version 7.3, but
hardknott uses gcc 10.3. Attempting to set the preferred version in
yocto after adding sumo's gcc 7.3 to the environment did not help.

Maybe you have some idea on how to set the __GNUC__ define for version
7 or some other way to have the linux kernel use gcc 7.3 instead of
the gcc 10.3?

Thank you again for your help, time and consideration.

With Best Regards.

Steven.

We are upgrading versions of Yocto and the current version of kconfiglib.py gives errors [2]. There is indeed an extra dot on line 20. Perhaps you have already fixed this in a later version  of this linux package so that we can avoid adding a patch? If so or if you have another solution, please advise accordingly. Currently your Kconfig file for this version of Linux is not compatible with the current version of  kconfiglib.
