[SOLVED]linux-grsec failed to build

suscyn · 2016-10-02 17:23:14

I'm trying to build myself the linux-grsec kernel from community repo and it fails. Building in clean chroot didn't help. Already reported bug here. Logs attached in same directory. End of buildlog is quite enigmatic to me:

For a start, you're looking for an error during compilation. The output you've posted only has warnings.

Looking at the build log you posted on the bug tracker, this is your error:

make[3]: *** Waiting for unfinished jobs....

A quick search brings up some results around the 15th June, including one hit on patchwork.kernel.org that has a patch to fix this. However, I can't test it works because one or more of the grsecurity patches are 404. Add the patch to the sources array and apply it in prepare, see how you get on.

EDIT: Wait, this patch is the opposite of what you need.

EDIT2: Looking at the linux 4.7 source code, dev_priv isn't used at the place where the error is occurring for you, so presumably one of the patches is changing the code.

Yeah, it makes sense now. I made mistake in my patch but can't find it in log because I expected that error will by at the very end of file not somewhere in the middle. How did you found it?

I'll try to build it now. Thx very much.

It's not at the end because you're running multiple jobs to speed up compilation, so although one job failed, the others continued to produce output until they terminated (which is why it says "make[3]: *** Waiting for unfinished jobs...."). You just need to search the log for "error".

It sounds like you're rolling your own patch? This is starting to sound like an X-Y problem. What is it you are trying to do?

BTW: Updating the PKGBUILD for 4.7.6 / 201609301918 results in a working package for me in a clean chroot.

It works for me too, thx again.

I needed patch to fix some regression which isn't solved yet upstream. I know that after the fact my first post lacks of information about this but if knew that the patch was the issue I wouldn't post it in the first place.

Anyway, You solved my problem.
