Distributing binary applications across linux distros

RPM and DEB packages are the two primary mechanisms for distributing binary packages in Linux. RPM is used by RedHat and its derivatives (Fedora, CentOS), while DEB is used in Debian and Ubuntu.

The .rpm and .deb files themselves are generally "dumb" archives, and are installed to the correct locations in the filesystem by pre-installed helper applications. You don't have to worry about writing scripts to install files, unless it's a very complicated application which needs special per-system configuration.

The usual patterns I see for distributing binaries are:

• Release a compessed tarball (.tar.gz or .tar.bz2), and let distribution packagers worry about the details. This works well for popular applications, but if it's newly released, nobody will care enough about your application to package it.
• Release as a tarball, plus RPM and/or DEB packages (depending on customer needs). Customers with a supported distribution may install the pre-made package. Anybody who's using an unusual distribution is probably happy to install from a tarball anyway.

MojoSetup is a user-friendly, perfectly cross-distro solution and nicely-licensed (zlib, very permissive). All it requires is the standard sh shell which comes with any Linux distribution. It also allows for desktop shortcuts the easy way by creating freedesktop.org spec shortcuts, which are supported by just about all graphical environments for Linux (so just dump in a PNG at different resolutions and fill in the blanks of the .desktop file).

Installers are scripted using the very simple Lua programming language and there are several example installer scripts in the Mercurial repository as well as a lengthy tutorial. There are also many years to back up its development into a lightweight cross-distro installer.

The rpm and deb will store the binaries. You'll need to have a different binaries for each distro or distro variant most likely, just because on different distros things are different like paths.

I recommend starting with the two you have rpm and deb and nail those two distro. Then maybe do a tarball for misc distros have people can extract and directory structure and copy and handle permissions on their own.

Also, for things like deb you can setup a site as a repository. That makes it easy for people to add the repo and get/install the deb in ubuntu very easily. A lot of 3rd party closed source devs do that.
