Most of the software I need are located in the ~PPC repository. These bits of software include octave-forge, octave, gnuplot-4.0 and vlc.

My question is, if I add ACCEPT_KEYWORDS="~PPC" to my make.conf file, how likely is it to break my system? Is there anyone here running ~PPC who can share their experiences?

~PPC and ~X86 is completly different IMO. The X86 platform has a lot more people working on it then the PPC platform. There's a ton of stuff that should be marked PPC but instead it stays ~PPC untill someone finds the time to change it. I've swtiched over to ~PPC and I'm not looking back. The only problem so far is Xorg locks up with my rage128 card. I'd say switch over. The PPC platform takes way too long for packages to mark stable anyway.

Yes I agree that the updates for ppc platform seem to lag behind x86 but by using /etc/portage/package.keywords you will have a better organized Gentoo install IMO. It depends what mission you are going to use the install for, ~ppc I feel should not be use in a server mission.

I did have some problems with a ~ppc install on a TiBook. Could not put my finger on the culprit but after going back to ppc and using /etc/portage/package.keywords for the ~ppc packages that I needed my problems went away. Remember when you run emerge with ~ppc you get the package as ~ppc and all the packages it depends on as ~ppc if they exist.

The last poster hit the nail on the head: if you want/need packages of a certain version that are key'd ~ppc , add the atom with ~ppc after it to /etc/portage/package.keywords, e.g. "cat-foo/barbarbar ~ppc".

You can also refine the atom you use even more so only a specific version get key'd for ~ppc. Checkout `man 5 portage` for more info.

If you feel you've used the package, and it's quite stable, and an entire month has passed, you can submit a bug to bugs.gentoo.org to kindly remind the maintainer to stabilize the package for ppc. (There may always be other reasons why unknown to you why it's not marked stable though.

xorg 6.8 has been problematic on PPC, including hardlocks with OpenGL and rage128, hence it being marked ~ppc and not stable as many arches already have. Really, some pacakges are marked ~ppc for a reason, some haven't been well tested, others are known to cause problems under certain configurations.

That said, if you do choose to use a package marked ~ppc, please follow fafhrd's advice. We don't have the time or the manpower to test and keyword everything. Let us know if a package has a bug or if a pacakge has been sitting in ~ppc for more than 30 days!

Thanks!

1 thing to add and 1 question:

If you want most of the ~ppc, then it might be easier to go ~ppc and use /etc/portage/packages.use to say the stable version (CAT/PKG -~ppc) for some packages than to specify which one ~ppc. Just depends on what you want to do.

My question: Is there any easy way of collecting the names of all the packages installed on my system with ~ppc so I can request ~ppc -> ppc of the ones I frequently use?

I have been using 'ppc' for a long time, but I ended up with 136 entries in package.keywords for a total of 750 packages installed. The problem with that was that emerge was very very slow. So I went to '~ppc', with as a result portage being a *lot* faster. Before "emerge -uDpv world" would take more or less 7 minutes, while now it only takes around 45 seconds. Except for some packages that don't compile (so i put them in package.mask for now), I haven't experienced problems with this.

@iTux:

If you have packages installed with '~ppc', while your arch is 'ppc', and you didn't put those packages in package.keywords, then portage will probably want to downgrade them if you do "emerge -uDpv world".

Gringo, what kind of powerbook are you using? TiBook? Pismo? Wallstreet? AluBook?

PostPosted: Sat Dec 11, 2004 12:10 pm    Post subject: My experience with ~ppc as default Reply with quote

This is my experience from about a year ago, so things might have changed since then.

I'm running a G3 with Gentoo, and had "ppc" as default. Then, not quite knowing what the consequences really were (this was the time when I was just getting used to Gentoo), I switched over to "~ppc". I was probably also using Portage in a very dangerous way, by including the "-U" switch. Anyway, the end-result after a while was a system which was totally unusable because of glibc version errors! After finally reconstructing the system, I've switched back to using "ppc" as default, and unmasking select packages via packages.keywords instead.

Correct me if I'm wrong but arn't there problems with ATi drivers and Xorg 6.8 in general?
https://forums.gentoo.org/viewtopic.php?t=249729&start=0

I've seen it a few places (not PPC particulairly though) but I havn't exactly seen it spelled out for sure 100% and current... I'm really bad at finding stuff though.

I did have the same problem when I switched to the 6.8.x version of Xorg. If I remember right, I had to switch off the extensions in /etc/X11/xorg.conf:

Code:
Section "Extensions"
        # Option                "Composite" "enable"
        # Option                "RENDER" "enable"
EndSection


and that did it. I run Gentoo ~ppc on a TiBook (1GHz) and it runs stable for me, including Xorg and Gnome. I used to run EvilWM instead of Gnome but ever since I updated Xorg it doesn't work anymore :-( (Filed a bug report but nothing happened so far)

Anyway, I'd say go ahead with ~ppc. The only annoying things about it is the load of compiling you have to do every now and then...

Cheers,
Jens :-)

yes, thats what i tried first, but it didnt help ... -r3 has been out for a while, will have a look to the changelog, maybe some ppc fixes are included.

Ati support sucks, there are no binaries for x86 + xorg-6.8.x and we dont have binary drivers for ppc. As said, its not a problem for me, its great to play with gentoo on my pb and i generally dont play opengl games ;)

cheers
