[gentoo-user] Graphite causing trouble

Hello list,

For the last few days I've been unable to emerge anything that needs a C 
compiler. I've started getting this error message in the logs:

$ grep Graphite /var/log/portage/perl-core:Sys-
Syslog-0.290.0:20120105-150502.log
Syslog.c:1:0: sorry, unimplemented: Graphite loop optimizations cannot be used

So I tried removing graphite by putting USE=-graphite in make.conf, removing  -
floop-interchange -floop-strip-mine -floop-block from CFLAGS and CXXFLAGS, and 
uninstalling ppl and cloog-ppl. I also remerged gcc, libtool and binutils, in that 
order, twice.

I still get the same errors. What can I try next?

What I did try was revdep-rebuild. The only package it wanted to rebuild was 
krita, so I thought what-the-hell and let it try. It worked. So now emerging 
is working again.

I didn't reboot, change any settings, poke around under the bonnet - 
nothing. I'm mystified.

Wait - only some things compile; others still throw up the error. I'm 
confused as well now.

If you just want your machine to work properly, you should probably
`emerge -e --keep-going world` until it does. Make sure graphite/lto are
disabled.

If it looks unrecoverable, you can probably unpack a stage3 over your
existing system and then update it.

Add "graphite" to the USE flags of sys-devel/gcc.  Then rebuild these:

   dev-libs/gmp
   dev-libs/mpfr
   dev-libs/mpc
   dev-libs/cloog-ppl
   dev-libs/ppl

Hopefully this should make the graphite optimization flags work again.

I rebuilt only gloog-ppl and that fixed the problem for me.

In order to get that done, though, I had to remove the -floop-* flags
temporarily because cloog-ppl gave the error that Peter describes.
Once that job was done I reinstated the -floop-* flags and all is well.

I wish I'd thought of that. Much quicker than emerge -e world twice! Mind 
you, on this i5 box it takes under five hours each time to remerge the 980 
packages, including Libre Office.

Two packages didn't compile: lame (wrong file size; I'll try again tomorrow) 
and kmymoney (compiled fine when called on its own, not during -e world).

To get things compiling I removed all signs of graphite. I'm not sure 
whether it's worth the trouble of putting it back in again. Thoughts, 
anyone?

On the one hand, it's kind of fun and educational to have something
break in a novel way so that you can figure out how to fix it.

On the other hand, those things only break when you have something
important to do.

I try to keep my laptop in good shape, and then do the unspeakable to my
desktop machine at home. If I ever need to do something urgently (fill
out a spreadsheet to apply for a scholarship) and something is broken
(libreoffice can't find libhahakissyournightgoodbye.so.1) I can always
walk into the living room and do it on the laptop.

FWIW, there was an update to ppl recently, whose postinst message warns of this:

Only snag, in my case, is that with passing years I'm beginning to find 
myself going round in circles, gnashing my teeth more loudly each time.

Now that's just paranoia! You only remember the breakages that coincide with 
inconvenience.

My unspeakable things aren't open to discussion in this forum :-)

But I do have an 8-year-old dual-Opteron box that I can do indescribable 
things to at whim. It still shows many a younger system a clean pair of 
heels but it is rather too noisy for everyday use, not to mention overnight.

Damn. I must have missed that warning. I'm sure you're right, that it's what 
caused my problem. Thank you.
