Re: Determining a .deb's intended Debian Version
Suppose you have a repository stuffed full of binary packages, in this case Debian Packages. If you were unlucky enough to have them in a rather un-organized fashion, I was just wondering if the package file itself would provide said information to allow me to write a program to sort them out. -- christopher Marc 'HE' Brockschmidt wrote: Christopher Crammond <[EMAIL PROTECTED]> writes: I was wondering if someone could provide me with some additional information related to Debian packaging.

No. Almost all packages in stable have been uploaded to unstable, were migrated to testing and then were released as stable. We would have to do new uploads for each of these transitions to keep such a field updated. Why do you need it, anyway?

Determining a .deb's intended Debian Version
Hello: I was wondering if someone could provide me with some additional information related to Debian packaging. Specifically, I would like to know if there is a way to determine which version of Debian that a package belongs to? For instance, the control file of the dpkg_1.10.28_i386.deb file looks like this: Package: dpkg Version: 1.10.28 Section: base Priority: required Architecture: i386 Essential: yes Pre-Depends: dselect, libc6 (>= 2.3.2.ds1-21) Conflicts: sysvinit (<< 2.82-1), dpkg-iasearch (<< 0.11), dpkg-static, dpkg-dev (<< 1.10) Replaces: dpkg-doc-ja, dpkg-static, manpages-de (<= 0.4-3) Installed-Size: 5636 Origin: debian Maintainer: Dpkg Development Bugs: debbugs://bugs.debian.org Description: Package maintenance system for Debian This package contains the programs which handle the installation and removal of packages on your system. . The primary interface for the dpkg suite is the `dselect' program; a more low-level and less user-friendly interface is available in the form of the `dpkg' command. . In order to unpack and build Debian source packages you will need to install the developers' package `dpkg-dev' as well as this one. I can see that the origin is indeed Debian; however, is there anyway to determine which version of Debian this is targeted for (ie. 3.0, 3.1, etc...)? As a comparison, RPM offers an optional field for Distribution. While not required, most packages to fill in this field and it provides of means of determine the intended flavor of Linux.

Re: Interfaces for dpkg/deb packages
Michael, That little example is very cool and sure do appreciate you taking the time to help me out. I got the source code and can take if from here. Thank-you very much. -- christopher Michael Vogt wrote: On Thu, Sep 15, 2005 at 02:40:06PM -0700, Christopher Crammond wrote: I was curious as to where I might be able to find out what non-command-line interfaces into .deb packages are available.

Interfaces for dpkg/deb packages
Greetings All: First-time poster, please be gentle. :) I was curious as to where I might be able to find out what non-command-line interfaces into .deb packages are available. For instance, is there a C interface that could pull out information such as Name, Version, Release, etc... ? I posted the above question on the debian-policy mailing list, and I got back that .deb is simply an AR file & that writing my own routines shouldn't be too hard. While I agree, I figure this is probably already done/documented somewhere else (say the dpkg project). Where is the right place to start asking questions? For instance, the parse.c file in dpkg-1.10.28/lib looks promising, but where can I get more information about this?
