WHAT IS IT?
|
||
-----------------------------------------------------------------------------
|
||
|
||
xbps - xtraeme's build package system.
|
||
|
||
It is a simple build package system that installs packages inside of
|
||
a chroot in a destination directory. Once the package has been installed
|
||
into this directory, you can make it appear/unappear at the master directory
|
||
at any time. It's in spirit the same than GNU stow, but the files are just
|
||
copied (there are no soft/hard links).
|
||
|
||
xbps has been designed for Linux, and for the moment I'm not interested to
|
||
make it work on any other random OS. I've been a NetBSD developer for some
|
||
years and I do not want to come back... also the experience has helped to
|
||
me to start xbps and not to use pkgsrc, which is very portable but also
|
||
not so fast.
|
||
|
||

|
||
REQUIREMENTS
|
||
-----------------------------------------------------------------------------
|
||
|
||
xbps uses proplib, a property container object library and it's almost the
|
||
same one available for NetBSD. Be sure to have it installed before using
|
||
xbps. You can get it at:
|
||
|
||
http://code.google.com/p/portableproplib/
|
||
|
||
I'm also the human maintaining the portable proplib package. I'd suggest you
|
||
to install it into /usr/local to avoid issues with your distribution packages.
|
||
|
||
Additionally the following software is required to be able to use xbps:
|
||
|
||
* GNU Make
|
||
* GNU Binutils
|
||
* GNU GCC (plus GMP and MPFR) development packages.
|
||
* GNU Bison
|
||
* GNU m4
|
||
* wget
|
||
* fakeroot
|
||
|
||
Super-user privileges are required as well, because all packages are built
|
||
in a chroot (except the ones that are included in a virtual package to be
|
||
able to build a minimal system for the chroot).
|
||
|
||
PLEASE NOTE THAT fakechroot or fakeroot-ng DO NOT WORK.
|
||
|
||
------------------------------------------------------------------------------
|
||
HOW TO USE IT
|
||
------------------------------------------------------------------------------
|
||
|
||
Before using xbps, some required utilities need to be built in the
|
||
bin and lib directories. You can do this by issuing "make" in the top level
|
||
directory and edit the configuration file located at the xbps directory.
|
||
By default it uses the xbps directory in your $HOME.
|
||
|
||
If configuration file is not specified from the command line with the
|
||
-c flag, it will first try to use the default location at
|
||
/etc/xbps.conf, and as last resort in the etc directory of the current
|
||
directory.
|
||
|
||
To avoid problems with libtool and configure scripts finding stuff that is
|
||
available in the host system, almost all packages must be built inside of a
|
||
chroot. So the first thing would be to create the binary packages with:
|
||
|
||
$ xbps-src.sh install xbps-base-chroot
|
||
|
||
This will build all required packages via fakeroot in masterdir, therefore you
|
||
can run it as normal user. Next commands will require super-user privileges
|
||
and all package handling will be done within the chroot. I believe it's the
|
||
most easier and faster way to handle clean dependencies; another reason would
|
||
be that xbps packages are meant to be used in a system and not just for
|
||
ordinary users. So once all packages are built, you can create and enter
|
||
to the chroot with:
|
||
|
||
$ sudo xbps-src.sh chroot
|
||
|
||
Press Control + D to exit from the chroot. The following targets will require
|
||
to be done in the chroot:
|
||
|
||
build, configure, install, install-destdir, remove, stow and unstow.
|
||
|
||
Now let's explain some more about the targets that you can use. To start
|
||
installing packages you should use the install target:
|
||
|
||
$ sudo xbps-src.sh install glib
|
||
|
||
If the package is properly installed, it will be "stowned" automatically.
|
||
``stowned<65><64> means that this package is available in the master directory,
|
||
on which xpbs has copied all files from DESTDIR/<pkgname>.
|
||
|
||
To remove a currently installed (and stowned) package, you can use:
|
||
|
||
$ sudo xbps-src.sh remove glib
|
||
|
||
Please note that when you remove it, the package will also be removed
|
||
from XBPS_DESTDIR and previously "unstowned".
|
||
|
||
To stow an already installed package (from XBPS_DESTDIR/<pkgname>):
|
||
|
||
$ sudo xbps-src.sh stow glib
|
||
|
||
and to unstow an already installed (stowned) package:
|
||
|
||
$ sudo xbps-src.sh unstow glib
|
||
|
||
You can also print some stuff about any template build file, e.g:
|
||
|
||
$ xbps-src.sh info glib
|
||
|
||
To list installed (stowned) packages, use this:
|
||
|
||
$ xbps-src.sh list
|
||
|
||
To only extract the distfiles, without configuring/building/installing:
|
||
|
||
$ xbps-src.sh extract foo
|
||
|
||
To not remove the build directory after successful installation:
|
||
|
||
$ sudo xbps-src.sh -C install blah
|
||
|
||
To only fetch the distfile:
|
||
|
||
$ xbps-src.sh fetch blah
|
||
|
||
To only install the package, _without_ stowning it into the master directory:
|
||
|
||
$ sudo xbps-src.sh install-destdir blob
|
||
|
||
To list files installed by a package, note that package must be installed
|
||
into destination directory first:
|
||
|
||
$ xbps-src.sh listfiles blob
|
||
|
||

|
||
PERFORMANCE
|
||
------------------------------------------------------------------------------
|
||
|
||
xbps is really fast, trust me. That was one of my reasons to make my own
|
||
pkgsrc/ports alike system.
|
||
|
||
If you want benchmarks, here is one: building libX11 and all its dependencies
|
||
required (not included building xstow) with xbps:
|
||
|
||
251.20s real 121.36s user 53.94s system
|
||
|
||
versus pkgsrc (make install clean clean-depends and digest previously
|
||
installed):
|
||
|
||
450.41s real 167.58s user 97.31s system
|
||
|
||
That's more or less 40% faster! that's the price you pay for having those
|
||
wrappers in pkgsrc that aren't very useful on NetBSD :-)
