@Przemek_Jeske Thanks for the feedback. We’ve encountered (and have had reports) of some crashes and incompatibilities when building on older distributions, which is why we’ve switched to building on newer versions.
By the way, we have builds on Ubuntu 14.04 which should have a version of glibc < 2.22. The portable and headless debs are also build on Debian 7
Let me know if you have further questions or if none of our current packages work for your use case.
