Hi All,
Built version 10 on my desktop and moved it to a partition on my laptop and ran
kernel make menuconfigand got this error:

kernel/sys.c: In function ‘override_release’:
kernel/sys.c:1245:28: error: expected expression before ‘>>’ token
1245 | v = ((LINUX_VERSION_CODE >> 8) & 0xff) + 60;
| ^~
make[1]: *** [scripts/Makefile.build:281: kernel/sys.o] Error 1
make: *** [Makefile:1756: kernel] Error 2

up to version 8.4, I could do that with a few minor changes with make menuconfig
but for some reason no luck since. Any ideas or help appreciated. Sure saves a lot of work when it works.
Thanks

In the top source diredtory (/usr/src/linux-version/) I would save the .config by some other filename, and then run
Which will zap everything, including the .config. But you have that backed up, so replace it, an try again.

Thanks for the help. I will give that a try. That will be great if it works.

I didn't have any luck with it . Guess I dont understand
that much about the .config file yet. Thanks fer the help anyway.

With various compiles done, the binaries and other stuff like .o files lie around in the source. This cleans them out. That's all.

Thanks for your time. I have a working system with a few bugs I am dealing with.
I had good success with 8.3,8.4 and 9.0. This version has gave me issues with
upower and gvfs for some reason. Upower daemon doesn't want to start and gvfs
not mounting usb drives . But everything else seems ok. Guess thats why we do this to learn
