Bug#625949: navit shows wrong coordinates if LC_ALL is set
Package: navit Version: 0.2.0+dfsg.1-1 Severity: important Steps to reproduce: 1) wget http://iki.fi/lindi/foxtrotgps/met-to-ota2.dump.xz 2) unxz met-to-ota2.dump.xz 3) gpsfake -c 0.5 met-to-ota2.dump 4) LC_ALL=fi_FI.UTF-8 navit 5) click on the map to get to menu 6) click Toiminnat (=Actions) Expected results: 6) location is 60deg 13' 52 N 24deg 24' 32 E Actual results: 6) location is 60deg 0' 31 N 24deg 0' 52 E More info: 1) upstream seems to consider this to be a known issue but I could not find a bug report about it. It definitely is an important issue since somebody might actually believe the wrong coordinates and setting LC_ALL should be pretty standard. The code has if (getenv(LC_ALL)) dbg(0,Warning: LC_ALL is set, this might lead to problems (e.g. strange positions from GPS)\n); but I could not figure out how to enable that dbg. It would also only go to debug log which the normal user is not going to notice. Upstream FAQ at http://wiki.navit-project.org/index.php/FAQ has My position is reported incorrectly Most of the time, this is caused by the decimal separator being incorrectly set. Navit tries to override the decimal separator at startup, but the LC_ALL environment variable can block this. You can check this easily : echo $LC_ALL If it returns something, you can't override your locale settings. You should unset LC_ALL and try again. If it works, you got it :) In gentoo, this is set in the /etc/env.d/somethinglocales. You may want to remove or comment the LC_ALL line in that file. which gives me the impression that they have lost hope and don't think this issue can be fixed. 2) Do you know which function ends up using the wrong decimal separator? Surely other programs in debian must be hit by the issue too? 3) Do you know if there's an upstream bug report about this somewhere? I only wrote svn change http://navit.svn.sourceforge.net/viewvc/navit/trunk/navit/navit/main.c?r1=2082r2=2125 that touches the warning that is printed when debugging is enabled (how?). 4) If all else fails, would it make sense to ship a wrapper script that unsets LC_ALL before exec'ing navit binary? In the debian changelog I see navit (0.0.4+svn1229-3) unstable; urgency=low * fixed a small bug in navit.pl: delete LC_ALL from the environment, instead of only undefining it. -- Carsten Wolff cars...@yet-another-geek.org Sat, 25 Oct 2008 21:07:46 +0200 but this has probably already been rewritten completely? -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/4 CPU cores) Locale: LANG=C, LC_CTYPE=fi_FI (charmap=ISO-8859-1) Shell: /bin/sh linked to /bin/dash Versions of packages navit depends on: ii libc6 2.11.2-13Embedded GNU C Library: Shared lib ii libdbus-1-3 1.4.6-1 simple interprocess messaging syst ii libdbus-glib-1-20.92-1 simple interprocess messaging syst ii libfontconfig1 2.8.0-2.1generic font configuration library ii libfreetype62.4.4-1 FreeType 2 font engine, shared lib ii libfribidi0 0.19.2-1 Free Implementation of the Unicode ii libgarmin0 0~svn320-1 Garmin image format library (runti ii libglib2.0-02.28.2-1 The GLib library of C routines ii libgps192.95-12 Global Positioning System - librar ii libspeechd2 0.7.1-5 Speech Dispatcher: Shared librarie ii libssl0.9.8 0.9.8o-5 SSL shared libraries ii navit-data 0.2.0+dfsg.1-1 Car navigation system with routing ii navit-gui-gtk 0.2.0+dfsg.1-1 Car navigation system with routing ii navit-gui-internal 0.2.0+dfsg.1-1 Car navigation system with routing ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages navit recommends: ii gpsd 2.95-12Global Positioning System - daemon Versions of packages navit suggests: ii maptool 0.2.0+dfsg.1-1 Converts OpenStreetMap maps to Nav -- no debconf information -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.

I'm attaching complete ~/.navit/navit.xml this time.
(process:6049): Gtk-WARNING **: Locale not supported by C library.
Using the fallback 'C' locale.
(unknown:6049): Gdk-WARNING **: locale not supported by C library
Does locale -a list fi_FI.UTF-8? If not, can you generate it with
sudo dpkg-reconfigure locales and try again?
Indeed. I can reproduce the problem now.
but I could not figure out how to enable that dbg. It would also only
go to debug log which the normal user is not going to notice.

Sure, I was just trying to point out that the current warning is not
something that people actually notice.
Sure. I've opened a ticket upstream [1] and set up a patch which, when
LC_ALL is set, unset it and set LANG instead.
Committed to my git repo and attached here.

Description: Set lang instead of LC_ALL to prevent decimal separator bugs
In case LC_ALL is set, unset it and set LANG instead.
