I would suggest a source-based distribution, because by definition you will have easy access to a wealth of development tools. I'm extremely happy with Gentoo for my own needs. Gentoo calls itself a meta-distribution, it is built to accomodate people who create their own distribution, and it does very well at this. I build my own distributions for my systems on a build server, and after pressing the build button it takes about a day until my laptop tarball with ca. 1000 packages including various crosscompilers and other nice things falls out, which I unpack to a fresh partition and find my system ready to use, with the same configuration that I like to always have, because that is of course included in the build. This may seem extreme, but what you want to do is not very far from it. The osmocom projects and GNU radio are quite volatile, frequently changing, and more or less require staying constantly on the bleeding edge to get the most out of the projects, and to be able to contribute back of course! Very few distributions are equipped to handle anything bleeding edge, and in particular binary based distributions are useless, because you have to wait for someone else to build that last commit. Not what you want. Not all work must take place under control of a package manager of course. But on the other hand, since it is possible, then why not? Especially when you have to deal with the dependency hell of larger packages such as GNU radio, not having to do *everything* manually like on Slackware is a big relief and a time saver. They are usually available in every distribution. But the separation in binary distributions between "user" files and "developer" files (there is usually one package with the binaries, and a -dev or -devel package with any development files provided by that package; headers and maybe static libraries and so on) I find unhelpful on a system whose intended use is development. Gentoo allows you to customize pretty much everything, but abstracts compile time decisions into a harmoized set of "USE flags", so you can say both globally and per-package if you want examples installed, if you want documentation installed, if you want JPEG support, what databases you want supported in a package (assuming upstream allows choosing) and so on. Gentoo also has a very nice tool called crossdev, for building cross toolchains, which of course also integrates with the system package manager. It's a different mindset, but if you enjoy being in control of your system, rather than your system controlling you, then I think Gentoo would be worth a try for you. There are of course also other source based distributions! Some have left Gentoo for Archlinux, and there are several others. I have never needed anything which Gentoo did not provide, so I never had a reason to look for anything else. :) I'm sure that other distributions have users with exactly the same experience with those! :) //Peter
