pkgfs - Build packages from s(cratch|ource)
|
||
|
||
It is a simple package system manager that uses Xstow to allow packages
|
||
to be available at a master directory.
|
||
|
||
Multiple versions of a package can be installed, because they can be enabled
|
||
or disabled at the master directory anytime, to e.g allow testing different
|
||
versions of the same package by "stowning" or "unstowning" them.
|
||
|
||
------------------------------------------------------------------------------
|
||
HOW TO USE IT
|
||
------------------------------------------------------------------------------
|
||
|
||
Once you download it, you should edit the configuration file located at the
|
||
pkgfs directory. By default it uses the pkgfs directory in your $HOME.
|
||
|
||
If PKGFS_CONFIG_FILE is not set or specified from the command line with the
|
||
-c flag, it will first try to use the default location at
|
||
/usr/local/etc/pkgfs.conf, and as last resort in current directory.
|
||
|
||
Once that you read the "pkgfs.conf" file and configured it, you can start
|
||
installing packages by using the command:
|
||
|
||
$ pkgfs.sh install glib
|
||
|
||
Please note that it's assumed that PKGFS_TEMPLATESDIR is properly defined
|
||
and actually contains valid template files.
|
||
|
||
While installing your first package, if pkgfs couldn't find the Xstow program
|
||
specified at the configuration file with PKGFS_XSTOW_CMD, the Xstow package
|
||
will be installed and "stowned".
|
||
|
||
If the package is properly installed, it will be "stowned" automatically.
|
||
``stowned´´ means that this package is available in the master directory,
|
||
on which ``Xstow´´ has created links from DESTDIR/<pkgname>.
|
||
|
||
To remove a currently installed (and stowned) package, you can use:
|
||
|
||
$ pkgfs.sh remove glib
|
||
|
||
Please note that when you remove it, the package will also be removed
|
||
from PKGFS_DESTDIR and previously "unstowned".
|
||
|
||
pkgfs uses some db(1) btree files, to record what packages are currently
|
||
"stowned". Once you install successfully or stown a package, the package
|
||
will be registered in PKGFS_DESTDIR/.pkgfs-registered-pkg.db.
|
||
|
||
While "unstowning" a package, it won't be available anymore in the master
|
||
directory and therefore it probably won't work if used from
|
||
PKGFS_DESTDIR/<pkgname>.
|
||
|
||
Summary, to stow an already installed package (into PKGFS_DESTDIR/<pkgname>):
|
||
|
||
$ pkgfs.sh stow glib
|
||
|
||
and to unstow an already installed (stowned) package:
|
||
|
||
$ pkgfs.sh unstow glib
|
||
|
||
You can also print some stuff about any template, e.g:
|
||
|
||
$ pkgfs.sh info glib
|
||
|
||
To list installed (stowned) packages, use this:
|
||
|
||
$ pkgfs.sh list
|
||
|
||
To only extract the distfile, without configuring/building/installing:
|
||
|
||
$ pkgfs.sh -i install foo
|
||
|
||
To not remove the build directory after successful installation:
|
||
|
||
$ pkgfs.sh -C install blah
|
||
|
||
To only fetch the distfile:
|
||
|
||
$ pkgfs.sh -e install blah
|
||
|
||
To only install the package, _without_ stowning it into the master directory:
|
||
|
||
$ pkgfs.sh -i install blob
|
||
|
||
That's all for now folks. I hope you find it useful, as I do.

||
PERFORMANCE
|
||
------------------------------------------------------------------------------
|
||
|
||
pkgfs 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 (all deps installed)
|
||
with pkgfs:
|
||
|
||
217.00s real 103.23s user 29.96s system
|
||
|
||
versus pkgsrc (make install clean):
|
||
|
||
229.22s real 112.75s user 54.79s system
|
||
|
||
The difference in this package might not be too big as I might think... but
|
||
anyway, 12 seconds faster is not that bad.
|
||
|
||

|
||
HOW TO MAKE TEMPLATES
|
||
------------------------------------------------------------------------------
|
||
|
||
A template in pkgfs is just a small text file with a few variables that are
|
||
required to build the package. pkgfs should be easy to work on, and
|
||
making templates shouldn't be too hard... if you have made any pkgsrc, it
|
||
should be trivial.
|
||
|
||
The required variables are: pkgname, build_type, extract_sufx, url
|
||
and checksum. Also there are some optional, like make_cmd, wrksrc,
|
||
configure_args, configure_env, make_build_args, make_install_args, etc.
|
||
|
||
Please take a look at the example.tmpl file located in the templates/
|
||
directory.
|
||
|
||
Also to help you creating templates and dependencies, there's a script
|
||
that will ask you some required information and will create the template
|
||
file once the distfile is downloaded: mktmpl.sh.
|
||
|
||
Try it and let me know if you have any problem or suggestion.
