I've tested the patched foxtrotgps this morning and can confirm: - it does not crash on startup anymore - it fetches missing tiles (I watched with TCPDUMP to make that sure); > I don't have a CURRENT machine to test this on.

I have an older VM with: $ uname -a FreeBSD vm-9Current 9.0-CURRENT FreeBSD 9.0-CURRENT #2 r220692: Sun Apr 17 03:28:12 CEST 2011 $ head Makefile ... # $FreeBSD: ports/astro/foxtrotgps/Makefile,v 1.3 2011/03/25 20:30:54 amdmi3 Exp $ # PORTNAME= foxtrotgps PORTVERSION= 1.0.0 PORTREVISION= 2 in this older kernel + ports the foxtrotgps works as well unpatched; maybe now in -CURRENT (and ports from SVN head) there has something changed in the Gtk shared libs; my patch contains a comment to some thread about a discussion of the same problem in tangGPS and I have just derived as I wild guess the change from this discussion (see the reply there from Kirill of 9th October 2012). For sure, one could compile gdk and gtk with debug symbols and step down with gdb to verify this. I will let this for someone else :-) > For what it's worth, my initial testing shows that map tile downloads > seem to work fine on 9.1-RELEASE with the patch applied, too. Good to know. I'd apply the patch to ports /head if it works for me and Pierre and does not break 9.1-RELEASE Thanks matthias -- Matthias Apitz t +49-89-61308 351 - f +49-89-61308 399 - m +49-170-4527211 e <guru@unixarea.de> - w http://www.unixarea.de/
