Use ccache
To enable ccache
, simply set the relevant variables in your
configuration bashrc
:
PATH="/usr/lib/ccache/bin/:${PATH}" CCACHE_DIR="/var/tmp/ccache" SANDBOX_WRITE="${SANDBOX_WRITE}:${CCACHE_DIR}"
You'll need to make sure that your ccache directory has appropriate permissions. Paludis
will sometimes use the paludisbuild
user when compiling.
You can set the maxium size of the cache by running (for example)
CCACHE_DIR="/var/tmp/ccache" ccache -M 2G
once as root.
Unmask a Package
First, you need to determine how a package is masked. The easiest way to do
this is to use cave show
. Then, if you're sure you really
want to unmask a package, and bearing in mind that doing so might break your
system, you need to override the mask. How to do this depends upon the mask
reasons:
- keyword
- You need to add an entry to your
keywords.conf
accepting one of the ebuild's keywords. The special-*
keyword cannot be accepted this way; if an ebuild only has this in its keywords, report it to Gentoo bug 160519 and work around it by using*
. An asterisk will also accept an ebuild with empty keywords. - user mask
- Either remove your
package_mask.conf
entry or override it withpackage_unmask.conf
. - profile mask
- Override with
package_unmask.conf
. - repository mask
- Override with
package_unmask.conf
. - eapi
- You cannot override this mask. It indicates either a broken ebuild (if
EAPI=unknown
) or an ebuild not supported by your current version of Paludis. - license
- Accept the appropriate licences in
licenses.conf
.
Sync from CVS
Syncing from CVS requires use of either the cvs+pserver
or the cvs+ssh
protocol.
The syntax for the configuration file line is
sync = cvs+ssh://username@host:/path/to/cvsroot:modulename
. As an example,
for syncing with the gentoo
repository via CVS, you would use
sync = cvs+ssh://username@cvs.gentoo.org:/var/cvsroot:gentoo-x86
.
Sync from a Gentoo tree snapshot
Syncing from a tarball requires the tar+http
or tar+ftp
protocol. You must also
specify sync_options = --strip-components=1
, as the
Gentoo snapshots place everything under a subdirectory
named portage
. For example:
# Replace this with your favourite Gentoo mirror sync = tar+ftp://my.favourite.mirror/gentoo/snapshots/portage-latest.tar.bz2 sync_options = --strip-components=1
Recover VDB
If you deleted /var/db/pkg
by accident, you're pretty much screwed. So don't do that, and be more
careful next time.
If you deleted /var/db/pkg
on purpose, please install OS X and stop pestering us.
Remove Portage from my Gentoo installation
The short answer is that you can't.
Several Gentoo packages wrongly depend on Portage, several depend on Portage because they use it and there really is no reason to try. Just leave Portage installed.
Update Configuration Files (etc-update
)
Paludis doesn't provide its own version of etc-update
. You can just keep using etc-update
or dispatch-conf
, since you can't remove Portage. Or, you can use
one of the workalikes that are available in the tree, such as app-portage/conf-update
, or
app-portage/cfg-update
.
Sync while doing anything else
If you think this'll work, buy a mac.
