[gentoo-user] escape from hell: kdelibs

[gentoo-user] escape from hell: kdelibs

[Philip Webb]

First, no criticism of Gentoo's hardworking devs intended or implied.

I thought I'ld try GCC 4.1.1, Glibc 2.4 & update to KDE 3.5.3 .
They're all still "testing", but we do have some responsibility to test,
& they've been there for a while without reports of painful experiences.

Having dealt with GCC & Glibc according to the docs,
I tried to compile Kdelibs 3.5.3 & got a long series of "can't find" msgs
followed by failure: there are a number of similar reports in the Forum.
Flameyes seems to give the authoritative response at Forum 060602 0917 :
  http://forums.gentoo.org/viewtopic-t-467029-postdays-0-postorder-asc-start-50.html?sid=759b61da629afeca0dfc16ee01411a17

Following this advice, I unmerged the previous Kdelibs
& tried again with the same result.  A bit more poking around
& I decided the best course was to return to the original state of affairs
& restore GCC 3.4.5, Glibc 2.3 & KDE 3.5.2 .  However when I did,
Kdelibs 3.5.2-r6 failed with the same error !  So recompile everything again
to try to make sure they were all in sync: same bad result !

Being experienced, I had made a quick-package of Kdelibs 3.5.2 ,
which I now tried to re-install via 'emerge -K': it refused,
demanding Qt 3.3.6 -- no longer in Portage -- , where I had 3.3.6-r1 .

Finally, I tried 'emerge -K --nodeps =kdelibs-3.5.2-r6', which worked !
I've rebooted & restarted KDE & all seems to be back to normal.

However, something is still not right with GCC 4.1.1, Glibc 4.2 & KDE 3.5.3 .
There was a recent request on Gentoo Dev for people to test things
prior to stabilising these items for the next profile, so I HTH (smile).

Anyone else have experiences to share ?  Any known-to-work solution ?

I didn't include it partly because I couldn't think where to look
-- after some sleep, I remembered  /var/log/emerge-logs  --
& also because it depends on what people are trying to compile:
there are similar reports with metabuilds in the Forum.
Here are what appear to be the relevant final lines

strange...

my only advise: go 3.5.3 - it is much more stable than 3.5.2 ever was.

[gentoo-user] kdelibs again: 'moc' & USE flags ?

[Philip Webb]

I just tried to update to "stable" Kdelibs-3.5.2-r6
(having returned everything to the previous GCC 3.4.5 & Glibc 2.4 state),
& it failed with the same lines as when I tried "testing" 3.5.3-r3 earlier:

The other failures reported on the Forum seem to involve 'moc' too :
what is 'moc' & how might it be related to this problem ?

Since I first emerged KDE 3.5.2 , I changed the USE flags in  make.conf :

  USE="-* apm bitmap-fonts bonobo bzip2 cdr crypt cups dri foomaticdb
     gdbm gif gnutls gpm gtk gtk2 imagemagick imlib java javascript jpeg kde
     libwww lm_sensors mime motif mozilla mpeg ncurses nptl nptlonly
     nsplugin nvidia opengl pcre pdf perl plotutils png pop python
     qt3 readline scanner session slang ssl
     tiff truetype truetype-fonts type1-fonts unicode usb X xml xv zlib"

The flags reported by 'emerge -pv' for 3.5.2-r6 are

  USE="-acl -alsa -arts cups -debug -doc -jpeg2k -kdeenablefinal -kdehiddenvisibility% -kerberos -legacyssl% -openexr -spell* ssl tiff* -xinerama -zeroconf"

Those for 3.5.3-r3 (slightly different) were:

  USE="-acl -alsa -arts cups -debug -doc -fam% -jpeg2k -kdeenablefinal -kdehiddenvisibility% -kerberos -legacyssl% -openexr -spell* ssl tiff* -xinerama -zeroconf"

It occurs to me that I might not have added back something needed by KDE
(NB I don't have a sound card & long ago removed all sound pkgs).

I am doing this while KDE is running, but that hasn't mattered in the past.

Does anyone have suggestions or enlightenment, before I file a bug ?

Do you have MAKEOPTS=-jN, with N>1?  If so, have you tried
"MAKEOPTS=-j1 emerge --oneshot kdelibs"?  It should not be necessary,
I thought KDE properly supported parallel builds, but this definitely
looks like that sort of problem.

Otherwise I suggest to post your emerge --info....

No: I have no MAKEOPTS (that line is commented).

That echoes a comment somewhere in the Forum.

It does. I usually compile kdelibs with distcc without problems.

I removed "confcache" from FEATURES & KDE 3.5.2-r6 emerged successfully !
I'll try 3.5.3 later after some sleep.

Is confcache considered stable ?  Should I file a bug about this ?

> (3) I still don't know what "moc" means: can you/anyone explain ?

I'ld still like to know what it is/does.

confcache is package.masked, you definitely should not file a bug about
it.

Hrm, confcache has also been known to cause strange problems, and in
fact is currently package.mask'ed.

Can you try "FEATURES=-confcache emerge --oneshot kdelibs"?

> (3) I still don't know what "moc" means: can you/anyone explain ?

I forget what the acronym means (meta-object compiler?), but it is
basically how Qt (and thus KDE) apps convert their user interface
files into .h and .cpp sources.  The idea is that moc is run against a
.ui file, which generates corresponding .h and .cpp sources, which are
then compiled with gcc.

Thus, in a parallel make, another thread could try to use the .h and
.cpp files generated by moc before moc has finished with them, leading
to missing files or undefined type errors.

Yes, as I now notice: it was "testing" when I set it up a few days ago.
Thanks (and to the other 2 respondents) for pointing this out.

Thanks for this partial enlightenment: I will file it away.

So having dropped Confcache, I'll try the whole exercise again.

FEI I've successfully updated to GCC 4.1.1 , Glibc 2.4 & KDE 3.5.3 .
The only problem is that Krusader fails, but there's a thread on Forum
& it is predicted that a new version now in CVS will solve things.
While Krusader is fun, I rarely have a use for it, so this is low-priority.

Out of caution in light of recent experiences (smile),
I didn't try 'kdehiddenvisibility', but may have a look at that too later.
Anyone have thoughts/experiences to offer ?

I am using it without any issues....although I don't know that I have
seen any benefit either.
