[SOLVED] package.keywords - a smart way to use

Message

Hello,

I use Gentoo stable packages (ACCEPT_KEYWORDS="x86") but I'd like to use latest xfce-base/xfce4 and sci-mathematics/scilab package therefore I put them in package.keywords file.

However if I emerge i.e. 'emerge -p scilab' with scilab in package.keywords file, it will install latest version of scilab but all dependent packages will be from stable profile.

Code: Select all

 emerge -p scilab

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] app-text/sablotron-1.0.1  
[ebuild  NS   ] gnome-extra/gtkhtml-2.6.3  
[ebuild  N    ] x11-libs/libzvt-2.0.1-r2  
[ebuild  N    ] sci-libs/lapack-config-1.0.1  
[ebuild  N    ] sci-libs/lapack-atlas-3.6.0  
[ebuild  N    ] sci-mathematics/scilab-3.1.1-r3

On the other hand if I do:

Code: Select all

ACCEPT_KEYWORDS="~x86" emerge -p scilab

These are the packages that I would merge, in order:

Calculating dependencies ...done!
[ebuild  N    ] app-text/sablotron-1.0.1-r1  
[ebuild  NS   ] gnome-extra/gtkhtml-2.6.3  
[ebuild  N    ] x11-libs/libzvt-2.0.1-r2  
[ebuild  N    ] sci-libs/lapack-config-1.0.1  
[ebuild     U ] sci-libs/blas-atlas-3.7.11 [3.6.0-r1] 
[ebuild  N    ] sci-libs/lapack-atlas-3.7.11  
[ebuild  N    ] sci-mathematics/scilab-3.1.1-r3

dependent packages will be also from unstable profile (~x86).

Do I have to add to package.keywords file also all dependent packages ??? That's a kind of hassle to me.
Also if I do 'emerge world' I got error messages about all dependent packages of xfce4 and scilab. Is there a smart way how to tell portage that I want xfce4 and scilab and also all depent packages to be ~x86 ?

Thanks
Jan

Adding them and their dependencies to package.keywords *is* the smart way of doing it...

Does that mean there's no other way around but to list desired package and its dependencies in package.keywords file ?
I tried also to add something like
'xfce-base/xfce4*' or 'xfce-base/*' in package.keywords but (as expected) didn't work.

You could run a fully ~x86 system by setting it in make.conf, but I woudn't recommend it.

Yes, I don't want to run fully in ~x86.

One more question:
If I run 'emerge scilab' with 'sci-mathematics/scilab' only in package.keywords it will install latest scilab but stable version of all dependencies. Will then scilab work ?
If emerging with 'ACCEPT_KEYWORDS="~x86" emerge scilab' then it asks for different versions of packages + some new packages....

Thanks

If you just unmask scilab in package.keywords, and it doesn't complain about any of its dependencies when you emerge it, then it should work fine with the stable dependencies. The scilab ebuild (even masked ones) should verify that all build and runtime dependencies have been met before it will install.

For xfce, just do something like this and you'll be fine for running the newest version:

Code: Select all

ls /usr/portage/xfce-base >> /usr/portage/package.keywords
ls /usr/portage/xfce-extra >> /usr/portage/package.keywords

But delete the metadata.xml entries it will copy.

I have no idea why the newest xfce is still ~x86. It's been out for ages and last I checked there were no bugs.

Most likely. The maintainer of the scilab ebuild will specify if it has any additional dependencies that are in ~x86. The emerge will notify you and fail even before it starts. But since it is ~s86, the only way to find out is to try. Yes, you will want to use the package.keywords method.

Thanks for all replies, I like the tip with xfce - easy and smart. For scilab I'll add everything manually to package.keywords file.

Cheers!

p.s. I'm still vondering if it woudn't be practical to allow * syntax in package.keywords file (i.e. xfce-base/* would unmask everything in xfce-base directory).
