[Aggiornamento Gcc]Ricompilazione sistema[risolto]

[effeuno]

Dopo aver aggiornato GCC, tutto ok, passo al comando:

emerge -eav system.

Errore!!!!

These are the packages that would be merged, in order

Parse error reading PROVIDE and USE in '/var/db/pkg/x11-base/xorg-x11-6.8.2-r4'
Possibly invalid: 'virtual/x11 opengl? virtual/opengl? opengl? virtual/glu virtual/xft'
Exception: Conditional without parenthesis: 'opengl?'

Calculating system dependencies ...... done!

Total 118 packages (........2 blocks)

Blocked Packages

Code Listing 18: Portage warning about blocked packages (with --pretend)

[blocks B ] mail-mta/ssmtp (is blocking mail-mta/postfix-2.2.2-r1)

Code Listing 19: Portage warning about blocked packages (without --pretend)

!!! Error: the mail-mta/postfix package conflicts with another package.
!!! both can't be installed on the same system together.
!!! Please use 'emerge --pretend' to determine blockers.

Ebuilds contain specific fields that inform Portage about its dependencies. There are two possible

dependencies:
build dependencies, declared in DEPEND and run-time dependencies, declared in RDEPEND.
When one of these dependencies explicitly marks a package or virtual as being not compatible, it

triggers a blockage.

To fix a blockage, you can choose to not install the package or unmerge the conflicting package first.
In the given example, you can opt not to install postfix or to remove ssmtp first.

It is also possible that two packages that are yet to be installed are blocking each other.
In this rare case, you should find out why you need to install both. In most cases you can do with one

of the packages alone.
If not, please file a bug on Gentoo's bugtracking system.


Come devo procedere???
Grazie.

N.B. avvo piu' pacchetti bloccati, ho gia' fatto un emerge -u portage !!!

Ma hai appena installato da un livecd 2006.0 o non aggiorni da otto mesi (xorg 7 è stabile da giugno scorso)?
Se hai appena installato ti consiglio di reinstallare da un livecd 2006.1, così trovi già gcc 4.1 e xorg 7.1 e devi perdere meno tempo ad aggiornare di quanto se ne prospetta attualmente.

Altrimenti, rimuovi pam-login (emerge -C pam-login) e segui la guida per l'aggiornamento di xorg, quindi riprova ad aggiornare tutto.

ti consiglio di cercare nel forum esistono N post con questi problemi. poi ti consiglio di leggerti questo .

nb: emerge -u portage per cosa lo lanciato??? dovevi aggiornare portage??? oppure volevi aggiornare l'albero di portage??? in quel caso il comando è : emerge --sync.

ciao
