Sorry; This output didn't bring any light into the problem.
Please try the following:
- download gpsdrive-2.10pre2 from http://www.gpsdrive.cc/
- unpack it
tar -xvzf gpsdrive-2.10pre2.tar.gz
- configure it with debug option switched on
cd gpsdrive-2.10pre2
./configure --with-debug
--> Send this output
- compile it
make
- start it with capturing the complete output
cd src
gpsdrive -D 2>&1 | tee gpsdrive_output.txt
---> Send this output
- start the debugger
cd src
gdb --args gpsdrive -D
- set a breakpoint
b 4717
- start the programm
r
- print the variables
on my box it looks like this:
Breakpoint 1, drawfriends () at gpsdrive.c:4717
4717 gdk_draw_pixbuf (drawable, kontext, friendspixbuf, 0, 0,
(gdb) l
4712 {
4713
4714 if ((posydest >= 0) && (posydest < SCREEN_Y))
4715 {
4716
4717 gdk_draw_pixbuf (drawable, kontext, friendspixbuf, 0, 0,
4718 posxdest - 18,
4719 posydest - 12, 39, 24,
4720 GDK_RGB_DITHER_NONE, 0, 0);
4721 gdk_gc_set_line_attributes (kontext, 4, 0, 0, 0);
(gdb) p drawable
$1 = (GdkDrawable *) 0x8256220
(gdb) p kontext
$2 = (GdkGC *) 0x8256268
(gdb) p friendspixbuf
$3 = (GdkPixbuf *) 0x818efd0
(gdb) p posxdest
$4 = 60.271915629473469
(gdb) p posydest
$5 = 180.92703781028297
(gdb) p GDK_RGB_DITHER_NONE
$6 = GDK_RGB_DITHER_NONE
(gdb)
So this is another try. I don't have any more ideas.
