Certainly, but can we please backtrack for a second? R has been in Debian since the laste 1990s. We never needed a TZ (nor should having one break it, but let's leave that aside for a second), and given all the releases and architectures we must by now have built a thousand times. Without FTBFS. So who now sets TZ and why? Can we just unset before / while R is built? R should work just fine with or without TZ. Most systems seem to have it; Debian never did and I am not aware of side effects (but we sometimes do set TZ in our (user) analysis scripts). So two things going forward: i) find out who set TZ, make him stop it (should take care of the FTBFS now) ii) contact upstream which I'll will and see what can be done about makeing the behaviour more robust (as it used to be prior to R 3.1.3 as well, I think) Dirk | | Best, | Philip | | | [1] | https://reproducible.debian.net/rbuild/unstable/amd64/r-base_3.2.0-2.rbuild.log | [2] http://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html | | | | -- System Information: | Debian Release: 8.0 | APT prefers testing | APT policy: (600, 'testing'), (550, 'unstable'), (500, 'testing-updates'), (450, 'experimental') | Architecture: amd64 (x86_64) | Foreign Architectures: i386 | | Kernel: Linux 3.16.0-4-amd64 (SMP w/4 CPU cores) | Locale: LANG=de_DE.utf8, LC_CTYPE=de_DE.utf8 (charmap=UTF-8) | Shell: /bin/sh linked to /bin/dash | Init: systemd (via /run/systemd/system) -- http://dirk.eddelbuettel.com | @eddelbuettel | e...@debian.org -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
