Installing Everywhere? 62

Posted by Cliff from the putting-the-code-in-all-the-right-places dept.
PlainBlack queries: "Our company has been developing an open source project for a couple years now that has gotten pretty popular. The one thing we haven't yet figured out how to do well is packaging. It seems like every operating system has it's own standards for packaging, and installers, and for each OS we support, we end up adding a lot of time to our packaging process. So my question is, what do all of you do to package your apps? Do you just release source tarballs? Do you manually package your RPMs, EXEs, DEBs, DMGs, BINs, PKGs, [and MSIs] by hand? Do you have an automated build process that creates all the packages? If so, how does it work? Is it available for other developers to use?" There are tons of installers listed on SourceForge, but which one allows the creation of OS packages without too much hassle? Duplicating work, especially software installation procedures, across all supported OSes, is time consuming. Is there an easier way?

    A self-extracting installer can be produced for every platform. Unless your application needs to become a part of the platform, it should be isolable, and installation should be as simple as expanding a self-expanding archive. Such archives can be produced for every popular platform. Using dependency=tracking packages is not feasible if you require that your installation model be cross-platform, but that's really no big loss: by including all of the dependencies for each application within the applications own directory, dependency conflicts are effectively eliminated.

      Right, when you are installing a complex server side piece of software, using an installer is a no brainer. But for simple apps, installers (on Windows at least) let users ignore where it gets installed to, and create shortcuts for launching it from the Start menu/Desktop/Quicklaunch bar. Next --> Next --> Next --> Finish. Simple. If you weren't using an installer, the process would be extract app to some directory, go to directory, and create sh

        Why not have the program offer to do this when it is first run? The user downloads an executable and it appears on their desktop. They then double-click it and it runs. It examines the start menu and if no link is there it pops up a question asking if you wan to install it. The user can say yes/no/later. If they say yes it adds the startup item.

    1) Put everything into one huge directory. Create all the symlinks and path extensions etc.

    2) Out things in the 'correct' directories (/usr/bin for exectuables, /ur/lib for libraries etc).

    On windows you don't really have that option, but you don't tend to run as many apps from the command line (which is the real reason there is a space in c:\Program Files\) And the tendancy is to put config stuff in the registry.

    If you really feel you need to do something original, you could as well not install at all, or use Zero Install [sourceforge.net] (Covered on Sweetcode [sweetcode.org] recently).

    But in general (if you are not running under an interpreter or emulation layer) all applications should install in a compatible way on any system, even when that is quite different from a system to another. So on Unix install in a reloctable directory tree with /usr/local/ as default (bin/, lib/, man/ etc/ etc.), and provide packages for distributions.

    The usual way to do that is to prepare make targets (such as "make debian" and "make redhat" and use the defualt packaging system everywhere. Not that I would know how to do that on Windows...

    You will have to distribute sources or build it yourself on each platform, and that represents the real problem. Getting the make targets right is the easy part - many free software applications contain that, and all distributions come with nice examples.

    (Besides, Debian's Package Builder [debian.org] makes for an excellent multiarchitecture (11!) compilation cluster and should be a good reason to provide and mantain debian packages.)

    It's less important for software to come "pre-packages" properly, but that both the code and the build infrastructure are written with portability in mind in the first stop.

    * Make sure your software compiles on non-i386 non-Linux (don't #include , don't assume /proc is the same on all Systems, don't use clone(2), etc).
    * Make sure it can be relocated (configure --prefix=/foo working properly if you have to use GNU autoconf).
    * Don't assume everyone uses GNU make
    * Don't assume /bin/sh == Bash

    • the build procedure is unusually complex, or
    • your program takes ridiculously long to build.
    I think most experienced Unix people are comfortable with building from source, and many people just don't trust third-party packages, as they're often badly packaged or out of date.

    If you decide to do it anyway, one tool that can help you is checkinstall [asic-linux.com.mx]. It monitors the standard make install process and can create several kinds of packages. I doubt the quality of the generated packages is very good though, and you still have to take in account that different distributions have different policies.

    Also, make sure you don't waste effort creating packages for distributions that already include your program. You mention DEBs, but whatever your program is, I'm pretty sure Debian already includes it :)
