Re: [gentoo-user] Problem building statically linked e2fsprogs

Hello

(Original post too long to quote)

How about building it dynamically and taking all the needed libraries as
well? I had similar problem (I needed fsck.ext3 in my init ramdisk) and
I just used ldd to find out what does it need.

You can test if it has enough by copying the thinks indo a directory,
chrooting there and trying out if it runs.

I hope it helps

I think the problem is that the drive (the server) is in a physically

Nevertheless, one can't help thinking the machine could be booted from

Ehm, exactly. So yes, it uses less libraries than before, but in no way 
is this a real statically linked binary:



This is true, but it is sufficiently static enough.  Pretty much any
Linux shipped within the past 10 years or so has GNU libc 2 .x (libc 6),
so the dependencies are satisfied.


Ah ? Are there no major difference between recent glibc versions ? I did 
not know that versions are so much compatible.



If you really really need static then:


No, it worked. However, the com_err library gave us no end of grief 
today. Mount was broken, fetchmail was broken, etc. And reemerging 
com_err yielded no results, the error


  "libcom_err.so.2: cannot handle TLS data"

persisted like a real plague. I finally fixed it, but am unsure how. I 
think reemerging an ancient version together with ss in the exact same 
version did the trick.  But something is badly broken-- com_err insists 
on running revdep-rebuild, but running that does NOT report problems 
related to any of the problematic binaries... :-(

As witnessed by, for instance, this:

master sys-libs # mkfs.ext2 --help
mkfs.ext2: error while loading shared libraries: libuuid.so.1: cannot 
handle TLS data


master sys-libs # revdep-rebuild --pretend --ignore
Checking reverse dependencies...



Checking dynamic linking consistency...
  broken /usr/lib/apache2-extramodules/libphp4.so (requires libpdf.so.2)
  broken /usr/X11R6/lib/apache2-extramodules/libphp4.so (requires 
libpdf.so.2)
  broken /opt/blackdown-jre-1.4.2.01/lib/i386/libjsoundalsa.so 
(requires libasound.so.2)
  broken /opt/blackdown-jdk-1.4.2.03/jre/lib/i386/libjsoundalsa.so

 done.



All prepared. Starting rebuild...

=dev-java/blackdown-jdk-1.4.2.03-r12 =dev-java/blackdown-jre-1.4.2.01-r1 
=dev-php/mod_php-4.3.10



In other words, no sign at all about this broken stuff. Same goes for 
fetchmail, but that has been reemerged so I cannot reproduce it anymore.


All in all, it has been a VERY BAD week for Gentoo from my perspective.
Which is a shame really, because I _want_ to love Gentoo... But... :-(


Another very bad thing which really bites us with our older Gentoo 
servers is the fact that having the CHOST set to *i386-* seems to 
harshly break any hope of a viable upgrade path. Figure that-- the main 
reason we chose Gentoo was, in fact, the possibility to seamlessly 
upgrade and thus stay up to date forever. That CHOST has killed that 
hope. Now IF someone back in 2004 had mentioned (or had known?) this 
fact we would not have fallen in this trap. But now, our management is 
pushing real hard to switch to redhat or some other 'terrible choice'.
I really really get angry and disappointed whenever I think about this 
situation nad how trivially simple it could have been avoided... :-(


I even think that the com_err thingy has some relations to this. Because 
'emerge world' has been effectively cut off for us, many many upgrades 
can be done only halfway, and these library problems indirectly stem 
from that.


If someone knows a solution to the CHOST=i386 problem that doesn't 
involve an 'emerge --emptytree world', I would LOVE to hear it...!


Thanks,
Maarten

Sorry, I am using a later version of e2fsprogs that does not have the
"static" USE flag.  I didn't know that earlier versions did have it but,
as another poster said, there is a bug for the package where use of the
"static" flag doesn't work.

If you really really need static then:

# cd e2fsck
# make e2fsck.static
# ldd e2fsck.static 
not a dynamic executable

Ah, that explains it.  Still, not too nice a fix they did on this.
Instead of really addressing the issue, simply "dropped USE=static".
(But what do I know, maybe it's truely quite complicated)

Anyway, I'll shut up before my frustration of today airs too much. :-)

Ehm, how do you figure that? It surely displays the "static" USE flag:

These are the packages that would be merged, in order:

So I would assume at this point the package is broken in this respect.

Good idea... well, maybe...

Ehm, exactly. So yes, it uses less libraries than before, but in no way 
is this a real statically linked binary:

However, since this might still perform much better, I tested it... 
and indeed, it does the job (despite different glibc versions between 
the build host and the bad server):

[gentoo-user] Problem building statically linked e2fsprogs

2008-09-24 Thread Maarten


Hi List,

I'm in a bit of trouble. A server or ours has a broken e2fsck because it 
is linked to a library version that doesn't exist anymore. Yes, I should 
have fixed this before-- but alas, I obviously didn't... :-(


Tonight, the server had a hard crash and the only way to get it up again 
(no IT people at the location) was by talking someone through a process 
wherein I replaced e2fsck by /bin/true so it would not complain at boot 
(where it would remain in an inaccesible state, with a panic shell).

So it is up and running again. All /seems/ fine, for now at least...

However, we must certainly assume the disk is in a dirty state so I 
really do not want to do more than the bare minimum to it. So emerging 
isn't a real good idea. Even then, I still tried. But it seems that 
-despite the state of the bug(s) about e2fsprogs which are in 
{resolved,fixed} state I cannot get e2fsprogs to compile AT ALL.

I've tried 10 different versions, etc., etc. To no avail. (Error below)
I believe looking at google and forum entries e2fsprogs on gentoo has a 
*terrible* track record of late by the way, but maybe that is just me.


Things get more complicated fast, because this server has a CHOST i386 
therefore -unless someone tells me otherwise- I cannot update glibc, and 
practise has taught us to not upgrade packages/libs left and right 
because you invariably end up, at revdep-rebuild time, with dependencies 
which are unsolvable "unless...". And it is the "unless" (meaning emerge 
-e world) which is unacceptable for this (or any production-) server...


It crashes on the "../../lib/libuuid.so: undefined reference to 
`___tls_get_addr'". The two bugzilla entries that apply basically tell 
me to rebuild from scratch, which I cannot do for reasons outlined 
above. (http://bugs.gentoo.org/204102 & http://bugs.gentoo.org/232743)



-in short-
So as to avoid any further messing with the box I opted for building a 
statically linked e2fsck binary on another box and copy it. However, I'm 
having no luck with that. I can build static binaries fine for other 
packages, but e2fsprogs refuses to build a static version.

(It builds, but the result is still dynamically linked)

Can anyone help with this ? Does this package not support building 
static ? The USE flag is there for a reason, no? Did I take the wrong 
approach here ? What is up with this [damn] package ?!?
