Watch out for the libpng 1.4 update

Zentoo

I've upgrade and I' got stuck too on the libpng upgrade.
After read all this thread I've try to have a sane system only based on libpng-1.4.2.

It seems impossible to have it.

After several 'revdep-rebuild -- --keep-going' and 'lafilefixer --justfixit', revdep-rebuild can't compile theses packages:

So it seems impossible to have a sane system whithout have a slotted libpng:1.2 !

My question is how to slot properly libpng:1.2 since libpng:1.4 have installed this:

x11-libs/qt-3.3.8b-r1 doesn't compile after update.

I think I'll preliminary keep libpng-1.4.2 masked.

hmmm. just noticed this thread. i've had libpng-1.4.2 masked (it broke stuff and the rebuild list had a bad smell about it, as i didn't have time for major breakage) but seeing that the huge revdep-rebuild has worked for some, i'm tempted to try updating. can someone confirm that this is worth doing now? i'm assuming it's going to have to be done eventually anyway.

otherwise, everything is working just fine with 1.2.43-r2 so i'm in no hurry.

Everything in ~arch will compile against 1.4.2 without issues, no point in postponing the migration.

And sure, dead software that's not in Portage, like kde-sunset will likely be screwed by this... but nobody never claimed them to be supported in the first place.

Annoyed by little Uli?

It was just an information, no offense.

Most everything compiled fine for me (using xfce not gnome or kde),
I did have to bump up a couple of packages to ~arch status
ghostcript being one, xfce was already using the overlay.

I've had worse upgrades, :lol:

though not many

Anything I can do to get opera-10.10 working with it?

Personally, I shudder whenever I see libpng come up in the list. Every new version comes well equipped with nifty, new bugs. Just now, in an apparent attempt to not break everyone's computer, they've made libpng-1.2.43-r3, which only installs libpng12.la so those poor souls who got a nice ramming from the 1.4.2 "update" can get something to satisfy those things that need libpng12.la to continue to operate. How nice...unless that causes emerge issues, which it does unless you also mask libpng-1.2.43-r3 and libpng-1.4.2. I guess portage wants to make damn sure we don't want this latest abortion...er I mean version.

If libpng-1.4.2 is going to break qt3, then I want no part of it. Despite the snarky attitude shown towards those of us who prefer KDE-3, there is nothing else in portage that works as well for what I want out of my machine. To suggest being forced to follow fashion is a good thing is lame.

I mean! Does the png format change so radically between versions that every new one has to break things? Sheesh!

Maybe instead of continuously dropping turds, the libpng people might want to consider making sure their "latest and greatest" doesn't destroy yesterday's used-to-work machine. Just a suggestion.

Cheers,
Pappy

Without the slotted older version of libpng, I cannot seem to emerge about a dozen packages, mostly gnome related. Not sure of what to do, I have run revdep many times, the libpng update script and several of the suggestion found in this topic on the forum, all to no avail.

No. Your facts are incorrect. You assume I emerged to a 64 bit system. I did not. I emerged it to this 32 bit laptop. Here is a snippet of the emerge log:

I had the same exact issue. It was caused by me having masked media-libs/libpng:1.4. You likely have it masked. Unmask it and things should start to work.

Edit: ssuominen beat me to it.
