Hi,quite a number of "FTBFS with gcc 5" bugs are hitting packages under the debian-science umbrella ; as I'm part of the team, I'll try to help on those, but since I have no clue what the problem(s) exactly is(are) yet, I have a few questions :
1. How can I set up a pbuilder with that compiler ? 2. Is there a wiki page somewhere listing the most frequent issue ? Thanks, Snark on #debian-science
