    <blockquote> <p>I would like a solution whereby a customer can click on the binary file in their file manager of choice, and it would run, no 'apt-getting' or 'yumming'. I don't mind breaking standards, and if it has to go in /opt, it will.</p> </blockquote> <p>First, you have to understand that "yumming" and "apt-getting" are not really the actual installers of the applications (packages), they are simply the front-end programs used to look up / download / update / trace packages on the repositories (from the distro and others that you manually add). So, when you say "no 'apt-getting' or 'yumming'", we have to assume that you mean that you don't want to put up your game on a repository, which makes sense if you want people to pay to get your game (as opposed to other proprietary but free software like flash, graphics drivers, video codecs, and other things you typically find in repositories).</p> <p>So, there are really just two types of package management systems, RPM and DEB, which use a command-line program, <code>rpm</code> and <code>dpkg</code>, respectively, to actually do the installation. Most distributions also come with a GUI front-end for those programs too (not the Synaptic-style package management software (which is a GUI front-end to apt-get or yum), but something simpler). When you double-click on a <code>.deb</code> or <code>.rpm</code> file, on most distros, you get this GUI front-end to pop up asking you for admin credentials and telling you about dependencies that are required, and, obviously, that you are about to install this package onto your system. From what I can tell, this is exactly what you want. And so, what you need to provide is a <code>.deb</code> file (for Debian distros) and a <code>.rpm</code> (for Red Hat distros), for both 32bit and 64bit versions of your game, just like I would assume you provide a <code>.msi</code> file for your Windows versions.</p> <p>As for dependencies that might be hard for users to locate. What you should do is include in some directory of your installer a number of additional ('recommended' version) packages for these esoteric dependencies so that they can be installed from those offline packages if a newer version cannot be fetched from the distro's repositories. And that's about it.</p> <p>And you can either make people pay to get the deb or rpm installers for your game, or include some kind of license-key system to unlock the game (and thus, make the deb/rpm files available for download, and charge for the key / code to unlock it).</p> <blockquote> <p>The ideal way for me would be to package it as a .zip or tarball and provide that a download, just like good ol' .exe files under Windows that work with system libraries.</p> </blockquote> <p>Ideal? Really!?! Yeah, if all you do is use system libraries, then it will work. But if there is anything more, it will be a nightmare (nearly as bad as it is under Windows of you don't rely on installers).</p> <blockquote> <p>The game is written exclusively using open source libraries, which are all cross-platform.</p> </blockquote> <p>Make sure none of those open source libraries are GPL-licensed, because if that's the case, you can't make your game proprietary. Your dependencies must be licensed under LGPL or BSD, or similar licenses, so watch out for that.</p>

    1. CO+1 for note re. licensing. This questions sounds suspiciously ill-licensed.

    2. COWow, thanks. I was actually referring to the problems of different versions of libraries being available in distro repos and so on to the ones we use. As for libraries, no, not GPL, what idiot releases low-level libraries as GPL anyway? But yeah, I guess it has to be packaged.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
