Emerge

Emerge es la interfaz que conecta a Funtoo con su administrador de paquetes: Portage. Con emerge es fácil instalar, actualizar o remover paquetes.

Actualizar la base de datos de paquetes

Sincronice los meta-repositorios. El siguiente comando actualizará el árbol local de Portage con las últimas versiones de ebuilds de Funtoo.

root # ego sync

Consulte app-admin/ego (Wiki Page) para obtener más información sobre 'ego'. También revise los manuales [manpages]: ego, ego-profile, ego-sync y la página wiki sobre Funtoo Profiles.

Buscar paquetes

Buscar paquetes por nombre.

root # emerge -s firefox
root # emerge --search firefox

Buscar paquetes por descripción.

root # emerge -S web browser
root # emerge --searchdesc web browser

Instalar paquetes

Instalar un paquete.

root # emerge firefox

Instalar múltiples paquetes.

root # emerge firefox thunderbird

Instalar un paquete. Solicitar la confirmación del usuario antes de realizar cualquier cambio. Mostrar una salida con más información.

root # emerge -av firefox
root # emerge --ask firefox

Eliminar paquetes

Eliminar paquetes.

root # emerge -C firefox
root # emerge --unmerge firefox

Eliminar un paquete. Solicitar la confirmación del usuario antes de realizar cualquier cambio.

root # emerge -aC firefox

Remover paquetes huérfanos. Solicitar la confirmación del usuario antes de realizar cualquier cambio.

root # emerge -a --depclean

Actualizar paquetes

Actualizar todos los paquetes.

root # emerge -uDN @world

Actualizar todos los paquetes. Solicitar la confirmación del usuario antes de realizar cualquier cambio. Mostrar una salida con más información.

root # emerge -uavDN @world

Cuando instale una versión nueva de perl, es necesario ejecutar este comando después perl-cleaner:

root # emerge -auvDN @world
root # perl-cleaner --all

   Note

Con el paso del tiempo, el requisito: perl-cleaner no será necesario, una vez que todos los ebuilds relativos a perl sean actualizados a la versión EAPI 5. EAPI 5 es la versión de Ebuild que ofrece la opción de 'smart updating' de paquetes relacionados con perl bits.

Opciones de emerge

--sync

Updates the portage tree that is located in /usr/portage by default.

--search -s

Searches for matches of the supplied string in the portage tree.

--searchdesc -S

Matches the search string against the description field as well as the package name.

--ask -a

Ask for confirmation before performing any changes.

--pretend -p

Instead of actually performing the merge, simply display what *would* have been installed if --pretend weren't used.

--unmerge -C

Removes all matching packages.

--update -u

Updates packages to the best version available, which may not always be the highest version number due to masking for testing and development.

--deep [DEPTH] -D

force emerge to consider the entire dependency tree of packages, instead of checking only the immediate dependencies of the packages.

--newuse -N

Tells emerge to include installed packages where USE flags have changed since compilation.

--depclean -c

Remove orphaned packages. Cleans the system by removing packages that are not associated with explicitly merged packages.

--autounmask-write

Automatically write package.use settings as necessary to satisfy dependencies.

--resume -r

Resumes the most recent merge list that has been aborted due to an error.

--jobs[=JOBS] -j [JOBS]

Specifies the number of packages to build simultaneously.

--load-average [LOAD]

Specifies that no new builds should be started if there are other builds running and the load average is at least LOAD (a floating-point number).

Configuration

make.conf

Emerge can be configured by editing /etc/make.conf to customize settings that are set in profiles. However, it's recommended to try to use Funtoo Profiles as much as possible to avoid having to clutter up /etc/make.conf. Also note that /etc/portage/make.conf is the same as /etc/make.conf -- they are symlinked.

   /etc/portage/make.conf - See Make.conf

Package.use

Per-package use flags can be configured in

   /etc/portage/package.use

x11-wm/dwm savedconfig
x11-drivers/ati-drivers qt4
media-sound/ncmpcpp visualizer clock taglib

package.accept_keywords

If you want to install a package that has not been tested on your architecture you need to edit

   /etc/portage/package.accept_keywords
