If your package is in Debian then it is automatically also in Ubuntu, Mint, Xandros, Univention, Aptosid, Knoppix and a few douzend more distributions which are all derivatives of Debian:

http://wiki.debian.org/Derivatives/Census http://www.debian.org/misc/children-distros

Roughly the other half(?) of the linux universe is based on Fedora, e.g.
CentOS, Red Hat:
https://fedoraproject.org/wiki/Derived_distributions

So by getting your package in the archives of Debian and Fedora, you should serve the large majority of linux users.

The Debian wiki has a list of advantages why somebody would want to have his software in a distributions archive: http://wiki.debian.org/AdvantagesForUpstream

Which is well and good, but doesn't address the problem that software developers face, which is "How can I make directly available binaries of my programs that will work for any Linux user?"

It's useful to be able to do that regardless of whether your software is FOSS and regardless of whether or not it's in distro repositories, because your latest release will always take time to propagate to the distros and because not everyone is comfortable compiling from source.

How would Debian Stable compare to, say, a five year old Ubuntu LTS that is still supported?

I'm not a Linux expert, but I'm fairly certain the answer is "You can't". Linux is very good at a lot of things, but standardization is definitely not one of them. Linux is just far too divergent ("herding cats" comes to mind) for a widely-compatible binary to be realistic. The best that can be done is make a dead-simple-to-use script to grab dependencies (isolated from the rest of the system if need be) and compile.

I think you're most likely right -- at least, it's impossible in the general case if not perhaps for a narrow band of widely-used distros.

It's just that I think people were answering a different question from that which the OP asked, and I think his actual question deserves a decent answer (even if it's a negative one).

There is only one Linux, well except that they keep evolving it and changing the version number. Linux is very standardized in that there is only one. There is no Linux divergence as there was UNIX divergence.

There are many, many, Linux-based distributions. The compilers vary, the version of Linux varies, the libraries vary, the packaging system varies. Binary compatibility across all of these is clearly impossible. This is not a problem, this is the antithesis of problem, as long as you allow the platform packagers to package or ship source and a build specification. Hence aptitude, yum, Waf and such stuff.

I've used alien a fair number of times, and its usually "just worked."
Here is an FAQ: http://www.debian.org/doc/manuals/debian-faq/ch-compat.en.html
That link provides a lot of info.

Honestly, unless Ubuntu has done something really weird, Debian should be just as compatible with non-Debian distros as Ubuntu is.  Give me a solid example of what you mean and I'll take a closer look.

Ubuntu has a Debian-for-Ubuntu-Devs page. https://wiki.ubuntu.com/Debian/ForUbuntuDevelopers
That should explain something at least.

How does Debian Stable compare to Ubuntu 8.04(Hardy Heron) LTS which loses support in April?
I'm not entirely sure.  http://packages.ubuntu.com/hardy/  http://packages.debian.org/stable/

I'm not saying it's incompatible, I'm asking :) BTW, I actually don't know how compatible Ubuntu either.

I guess I'll to take a look at that page.

As I understand it Debian is a more stable distribution and Ubuntu is a faster moving target. The question is how much faster. Would Ubuntu LTS be more ahead of compared to the latest stable Debian.

Debian testing is a rolling distribution, so it is always in an unstable state. Debian stable is, as it says, stable. To answer your question, just look at what debain version the particular ubuntu LTS version is based on.

To be honest, unless you're going to package all your dependancies along with the download, then you have to go down one of two routes: source distribution with a nice simple build procedure or making packages for the main distributions. I would recommend doing both.

Look at it this way: the sort of people who aren't using a debian or fedora based distro aren't going to be phased by building from source (as a matter of fact they might prefer it).
If you provide packages for debian and fedora and a source distribution as a fallback then you've covered the vast majority of your bases, allowing less advanced users to use package managers and letting the wild-west fringe distro people do whatever they want.
