Compile of usermode-sources-2.6.x fails

------- Additional Comments From [email protected] 2005-06-06 17:57 PDT ------- Ok, I hope there is still somebody using UML on a NPTL-only system. The workaround suggested last time was to avoid enabling CONFIG_MODE_TT; now I think I've got over this problem, too. So, when I release 2.6.11.8-bs6 (which will happen very shortly, I hope), I'd like to get some testing from you about this issue.
Thanks a lot.

I can give it a try if you like.
(That's a MODE_TT build on a system with NPTL headers, right?)

With NPTL-only glibc, I meant (and I guess you mean too).
Just give me the time to actually upload the tree, which I'm doing at the moment, and forgive me if I added anything ruining the compilation while I was working on x86_64 host.
Ok, done... enjoy!

Well, I've got a dual non-NPTL glibc in /lib and NPTL glibc in /lib/tls, but I can force use of either, and the headers, the dynamic loader, and everything other than the stuff in /lib come from the NPTL glibc build. This is pretty much indistinguishable from a pure-NPTL system unless you force LD_ASSUME_KERNEL, which I'm not.

Building now, atop Linux-2.6.11.10. More in a few minutes when the build completes, in whatever way.

Patch mis-rolled, I guess: arch/um/scripts/Makefile.rules is missing, yet included from multiple places:
CHK usr/initramfs_listarch/um/kernel/Makefile:34: arch/um/scripts/Makefile.rules: No such file or directory make[1]: *** No rule to make target `arch/um/scripts/Makefile.rules'. Stop.
make: *** [arch/um/kernel] Error 2
(I could grab the copy from -bs5, but I don't know if it's changed since then, or even if it's still meant to be there at all. I could check the -broken-out, but I have no guarantee that that isn't equally confused :) )

Yeah, the headers differ.

Not quite built without problems. Can you guess the cause of this?
Guess where the static libutil.a is. That's right,
/usr/lib. Are we searching it in that linker script? No :(
Ok, wait that I emerge that newer version and build starts failing here too and you'll get that fixed. A proper patch (ok for whatever SUBARCH you need) would be ok, either... Ok, it's doable because I must now link in arch/um/sys-SUBARCH/unmap_fin.o (it's done in -bs6 too), by passing -DSUBARCH=$(SUBARCH). You can pass a define for the path, too.

From: Paolo 'Blaisorblade' Giarrusso <[email protected]>, Al Viro <[email protected]>
To make sure switcheroo() can execute when we remap all the executable image, we used a trick to make it use a local copy of errno... this trick does not work with NPTL glibc, only with LinuxThreads, so use another (simpler) one to make it work anyway.
Hopefully, a lot improved thanks to merging with the version of Al Viro (which had his part of problems, though, i.e. removing a fix to another bug and not fixing the problem on i386).

OK, so it's a -static TT build that's failing?

Exactly.
Built, with a randomly selected .config (that is, a .config I use for other things, not a .config with the values set at random!)
Hmm, broken-out in the archives works perfectly (with patch-scripts). Go until uml-link-tt-mode-against-nptl.patch and retry, and possibly even with the previous one... please.
Hmm, ok, it works perfectly here in SKAS mode, not in TT mode (I'm enabling both), but it's different, so there is something wrong there... maybe it is the NPTL glibc. If you can confirm that, I'll have one less problem (fixing things for NPTL glibc will still be an issue, but that is not urgent).
Urgency is the keyword here.... I have the exam season now so I *must* study.

usermode-sources-2.6.12 is in portage. Please test it (see comment #51) as it should solve the NPTL issues.
Hi,
I'm using glibc-2.3.4.20041102-r1 compiled with the USE="nptl nptlonly".
Finally i was able to build an uml kernel from the source with this "mix"!!! i patched the host kernel (gentoo-sources-2.6.12-r4)
with this patch:
http://www.user-mode-linux.org/~blaisorblade/patches/skas3-2.6/skas-2.6.12-rc4-v9-pre4/skas-2.6.12-rc4-v9-pre4.patch.bz2
then i emerged the usermode-sources-2.6.12
and in the kernel configuration
i disabled CONFIG_MODE_TT
and enabled CONFIG_SKAS
(see comment #41 by BlaisorBlade)
NOTE1: when CONFIG_MODE_TT is disabled in the guest kernel (uml) the host kernel must be patched with the skas patch.
NOTE2: i would like to thank you all! :D

------- Additional Comments From [email protected] 2005-07-12 10:13 PDT ------- Ok, a couple of notes:
1) You'll probably like to upgrade your SKAS patch to V8.2 or V9-pre7, since they fix an important bug which could affect apps other than UML (difficult to trigger since you use NPTL, anyway).
2) With the latest patch for UML on my site, 2.6.12-bs5, you should be able to enable TT mode and still get a successful compile, it was tested on FC4. That tree will be probably added in portage (see bug #98785).
3) I think that even in past releases UML compiled for NPTL-only systems, if enabling SKAS and disabling TT.

thanks for the tip, updated the host kernel

you are right,
patched a vanilla 2.6.12 with this patch, now i can run an uml kernel compiled with CONFIG_TT and CONFIG_SKAS enabled on my nptlonly system.

Since when did sending a "go look at this URL" message to a development mailing list, with no further information outside of the message subject, not count as spam? Especially when three or four further follow-ups are equally unintelligible if you don't follow the link to the URL in question?
Just curious...

Ah, I see. I was thrown off by the formatting, there is a little info at the bottom there. (Mentally edited it out as a signature.) Ok...
