[DISCLAIMER]
Dieser Beitrag enthält ein unzureichend getestetes Skript. Benutzung auf eigene Gefahr.
Das Skript habe ich bisher nur unter Portage-2.0.51 getestet. Falls es wider Erwarten auch mit 2.0.50 funktioniert, bitte hier posten. Alle weiteren Kommentare, Flames etc. ebenfalls hier rein.
[/DISCLAIMER]

Quote:
!!! All ebuilds that could satisfy "=xorg-x11-6.7.99.902" have been masked

Manchmal wünscht man sich das alte "ACCEPT_KEYWORDS=~arch emerge <pkg>" zurück, da es auf die Dauer lästig ist, von Hand die Einträge in package.* vorzunehmen. Abhilfe schafft ein kleines Script, das den letzten emerge Befehl analysiert und alle notwendigen Einträge in package.* macht. Das ganze sieht dann so aus:
Quote:

$ emerge =xorg-x11-6.7.99.902
Calculating dependencies
!!! All ebuilds that could satisfy "=xorg-x11-6.7.99.902" have been masked
!!! One of the following masked packages is required to complete your request:
- x11-base/xorg-x11-6.7.99.902 (masked by: package.mask, ~x86 keyword)
# <seemant@gentoo.org> (13 Aug 2004)
# Masked for TESTING by DEVS and ARCHES!


For more information, see MASKED PACKAGES section in the emerge man page or
section 2.2 "Software Availability" in the Gentoo Handbook.

$ epo

* Starting emerge in the background. Please wait a while...
$ emerge =xorg-x11-6.7.99.902 --pretend 2>&1 [ ok ]
* Looking for packages to add to package.{unmask,keywords}

* =x11-base/xorg-x11-6.7.99.902
* will be added to /etc/portage/package.unmask

* =x11-base/xorg-x11-6.7.99.902 ~x86
* will be added to /etc/portage/package.keywords

* Do you want me to apply these changes?
Please type "Yes" or "No" Yes

* Starting emerge in the background. Please wait a while...
$ emerge =xorg-x11-6.7.99.902 --pretend 2>&1 [ ok ]
* Looking for packages to add to package.{unmask,keywords}

* Nothing to do. The last emerge command was
* emerge =xorg-x11-6.7.99.902
* Do you want me to re-run it?
Please type "Yes" or "No" Yes
Calculating dependencies ...done!
>>> emerge (1 of 1) x11-base/xorg-x11-6.7.99.902 to /
...

Zur Installation des Skripts genügt folgendes:
Code:

wget -P /sbin http://www.stud.uni-karlsruhe.de/~uxhz/gentoo/misc/epo
chmod +x /sbin/epo

Sobald beim emergen die "!!! All ebuilds that could satisfy ... have been masked" Fehlermeldung kommt, einfach "epo" starten.
Das funktioniert allerdings nicht mit "--pretend" (-p), da dieser Befehl nicht in emerge.log landet. Der Vollständigkeit halber hier das Skript:
Code:

Ja, so in der Art... /etc/portage sollte drinstecken, und das Wortspiel konnte ich mir dann nicht verkneifen 8)

Irgendwie habe ich das Prinzip noch nicht durchschaut...

Ich hab folgenden Update Befehl:

LINGUAS="de" emerge -u -D --newuse world

Wenn ich den starte, kommt:

Code:

tobi-rechner filme # emerge --update --deep --newuse world
Calculating world dependencies -
!!! All ebuilds that could satisfy ">=x11-libs/cairo-0.9.2" have been masked.
!!! One of the following masked packages is required to complete your request:
- x11-libs/cairo-1.0.2 (masked by: ~x86 keyword)

For more information, see MASKED PACKAGES section in the emerge man page or
section 2.2 "Software Availability" in the Gentoo Handbook.
!!!    (dependency required by "x11-libs/gtk+-2.8.6" [ebuild])


!!! Problem with ebuild app-office/dia-0.94-r3
!!! Possibly a DEPEND/*DEPEND problem.

!!! Depgraph creation failed.


Soweit so gut.

Dann epo:

Code:
tobi-rechner filme # epo

 * Starting emerge in the background. Please wait a while ...
$ emerge --update --deep --newuse world --pretend 2>&1                                                                                                                      [ ok ]
 * Looking for packages to add to package.{unmask,keywords}

 * Nothing to do. The last emerge command was
 *  emerge --update --deep --newuse world
 * Do you want me to re-run it?
Please type "Yes" or "No" Yes


Und nun? Hm.....


Danke

Nee. Normal im Terminal.

Ich glaube, er hat das Problem, dass in emerge.log kein Fehler abgespeichert wird...

Soll heißen: Er sagt nicht, dass dieses und jenes Programm masked ist.

Die Fehlermeldung wird von der Ausgabe von emerge übernommen. Dort fängt er die Zeile - x11-libs/cairo-1.0.2 (masked by: ~x86 keyword) ab. Ist in der Ausgabe das ~x86 grün?

Das ist rot.


=gcc-4.0.2-r1 <-- Das ist grün.

Der Rest ist schwarz.

Auch masked by: -* keyword ist schwarz.

Hi Earthwings,

Erstmal Lob für dein Tool! Gerade bei xorg-7 ect. sehr hilfreich!

Allerdings greift dein Suchmuster wohl nicht bei z.B

Code:
emerge -pv e KEYWORD=-*


Etwa so könnte man die egrep-Zeile im epo-script bei Zeile 74 erweitern.

Code:

egrep "masked by: [-~].* keyword" | cut -d " " -f 2,5 | sort | head -n 1


Gruß Qubit.
