Kernel error

[Nokobon]

Hello,
after learning how to log the error
here it is.

I tried to build a custom kernel but got the following error

linking kernel.debug
nlm_advlock.o(.text+0x11a8): In function `nlm_advlock_internal':
/usr/src/sys/nlm/nlm_advlock.c:225: undefined reference to `nfs_vinvalbuf'

*** Error code 1

*** Error code 1

Stop in /usr/src.

It's the first time I try to build a custom kernel therefore I have no idea what is causing the error.

I read the thread Custom Kernel Error. It didn't help me that much, as I can't find any entry that requires another missing one.
And because I can't find words like "nlm" or "advlock" in my kernel, I hope to get some advice from you...

In the attachement there is my modified kernel.

Thanks.

My guess: you have

options 	NFSLOCKD

but you do not have one (or both) of these:

options         NFSCLIENT
options         NFSSERVER

If you don't need NFS at all (which is what I gather from the absence of those options), remove that NFSLOCKD as well. Remember to clean out /usr/obj before building again -- # rm -rf /usr/obj is fine.

Aside: I remember that SCTP needed INET6, but I'm sot sure if that's still the case. I'd suggest either using both, or removing both.

Thank you for your help.
Commenting the NFSLOCKD-entry out solved the problem. I have no idea why I didn't do that before...
For just a webserver with Apache I don't need any NFS, do I?

Well I don't really understand whats SCTP for but I think it doesn't require INET6.

Remember to clean out /usr/obj before building again -- # rm -rf /usr/obj is fine.

Ok, I cleaned it up before building the kernel.
But what is that directory for?

It's where your build world and kernel ends up. It'll be installed from there.

Well, not too long ago (in the 7 era certainly) the kernel refused to build with SCTP and without INET6. I had to add the latter, or remove the former.

It's where your build world and kernel ends up. It'll be installed from there.

And not removing it before a fresh build may result in already built code being reused (and failing again for that reason).

Okay, so everything in /usr/obj is just important for the build of a kernel and after this I can(or even should) delete it?

Thank you for your explainations

Once you're done installing world and kernel /usr/obj can be safely removed.

I have /usr/src/ and /usr/obj/ nfs exported read-only. That way I can build on my fast machine and just mount them on the slower machines to do the install.

Okay, thank you.

I have only one testing machine with FreeBSD so exporting the directories is no option for me...
