as osmo-trx has recently introduced a dependency on a super-recent version of UHD (as opposed to what regular stable distributions ship), the nightly debian builds are broken for both Debian 8.0 and Ubuntu 14.04: https://build.opensuse.org/package/show/network:osmocom:nightly/osmo-trx

I bumped the UHD version dependency to 3.9.x because older versions of UHD are no longer maintained and osmo-trx was already dependent on 3.9.x for certain functionality (mainly multi-trx and improved timing). Build-time version checks were also causing user confusion.

It is sad that Ettus depreicates those versions that are shipped by the major stable distributions. This means that anyone basing their projects or products on stable versions of those major distributions / OS vendors will run into trouble. I consider that quite questionable, but it is of course not my call and there's nothing we can do about it.

I understand the unwanted effects and dislike the idea of forcing users to move to more recent versions, however, Ettus Research does not recommend building against the shipping 3.5 and 3.7 UHD versions in Ubuntu 14.04 and Debian 8.0 respectively.

That's Ettus' decision. However, when you introduce a dependency into osmo-trx which breaks our official nightly package builds, I would argue it is also your responsibility to resolved that in some way, or at least to provide a solution to that problem :)

Recommended UHD versions are found in Debian 8.0 Backports and Ubuntu 14.04 Ettus Research PPA.

Do you know how to add that dependency on external binary package repos to OBS? Or do we have to re-build the soruce packages as part of the OBS build? Would you be taking care of this if we provide you with the respective privileges on the osmocom OBS build?

Adding the backports repository should be sufficient for Debain builds. I'm not familiar with the details of the OBS. Given access, though, I can figure out the dependency settings if there is nobody else is in a better position to do so.

Well, I would do it, but it's all new to me and I have a pile of tasks this high, way beyond late... so personally, I would highly appreciate if I could pass it on to you. The first step would be to create an account on https://build.opensuse.org/ and communicate your user name to Holger, so that you can be added to the osmocom-nightly project. From there on, Holger would be your guide, I assume.

For the record, using jessie-backports I successfully installed a recent UHD on a Debian-jessie based build server and built osmo-trx master. Helpful: https://backports.debian.org/Instructions/ In short: Add to /etc/apt/sources.list: deb http://ftp.de.debian.org/debian jessie-backports main Then: apt-get update apt-get -t jessie-backports install libuhd-dev It would of course be even nicer if UHD 3.9 were in the "normal" jessie packages, but this is the next most convenient way. ~N
