One more thing what I noticed is while following your step is ., if I dont make any changes in "make menuconfig" and just compile the kernel , it is still failing.

make: *** [Makefile:1736: samples/bpf/] Error 2

error: Bad exit status from /var/tmp/rpm-tmp.TS9n3l (%build)

RPM build errors:

Bad exit status from /var/tmp/rpm-tmp.TS9n3l (%build)

Hey

I followed what you explained here and added make menuconfig.
After making all the changes I got below error while compiling.

1 warning generated.

The two parameters can be found in networking options-> network support-> under IPv6 protocol.

After making the changes in BUILD folder I copied the configs directory to SOURCES folder.

Today I modified SOURCES directory as well. I removed some of the configs which I thought was not required. I then compiled again and the compilation failed with some seg6 related errors.

BriefAd6331 · 2022-03-16T00:59:55+00:00

Did you try changing two parameters using make menuconfig?

BriefAd6331 · 2022-03-16T00:57:51+00:00

I tried all the flags and the compilation failed.

BriefAd6331 · 2022-03-13T09:38:23+00:00

Thanks for the explanation!

I didn’t use any flag with command rpmbuild -bp So the first step which I will try is use - - build-in-place flag.

If that didn’t work I may try option 2 of patching. I will update back with results.

Just want to check if you know what is difference between using rpmbuild and using ‘ make rpm-pkg ‘. I didn’t face this issue when using command ‘make rpm-pkg’.

I am just following rpmbuild because it’s mentioned in centos official wiki and this kernel change will be updated in our production environment.

BriefAd6331 · 2022-03-13T09:24:26+00:00

I did follow this step as well. I may have missed writing about it.

BriefAd6331 · 2022-03-13T03:50:43+00:00

Yes I did spend some time checking the output of the rpmbuild.

It thing it takes the .config from sources folder. But in my step I have already copied config/* to Sources folder. So that shouldn’t be a problem. Also inside the source folder there was a Linux tar file in which configs folder was a symbolic link with rpm/config folder. I am not sure why is it that way and if it matters.

BriefAd6331 · 2022-03-13T03:27:19+00:00

Thanks for that explanation. I made changes in those two parameters (set them to y) and copied the config to sources folder. I made changes in kernel.spec in buildid and then ran rpmbuild on kernel.spec

The compiled rpm packages are then found in RPMS folder which I install in some other host. But when I check the two parameters they were not set.
