I have all of my maps ( many dozens of uscNNNNN.rdm files for each state ) in the maps directory: /mnt/cf/QtPalmtop/share/roadmap/maps

When I load mine from the desktop (in 640x480 mode), it pops up a window that says: \"An error occured when opening the selected trip\". (I didn\'t select any trip. ??) When I click \"ok\", the program closes. This happens on all 3 version of the IPK linked above (2 links... 1 link has 2 IPKs).

In the terminal:

Code: [Select]

bash-2.05$ cd /home/QtPalmtop/bin

bash-2.05$ ./roadmap

Some messages appears quickly in the Terminal and then the GUI application pops up with the same \"An error occured when opening the selected trip\" message. When I click \"OK\", the program closes again and I\'m back in the terminal which says:

Code: [Select]

bash-2.05$ cd /home/QtPalmtop/bin

bash-2.05$ ./roadmap

Display size = 480x640

could not open translation file /home/QtPalmtop//i18n/zh_TW/libs1.qmid

filename:/home/QtPalmtop/lib/fonts/arial_140_50_t10.qpf

fontName:lcfont , size:10

s## roadmap_locator.c, line 144: cannot open directory database (usdir)

 == roadmap_gps.c, line 232: cannot access GPS source gpsd://localhost

s** roadmap_file.c, line 70: cannot open file /home/zaurus/.roadmap/trips/default

bash-2.05$

Part of the message above I\'ve seen before:

Code: [Select]

Display size = 480x640

could not open translation file /home/QtPalmtop//i18n/zh_TW/libs1.qmid

filename:/home/QtPalmtop/lib/fonts/arial_140_50_t10.qpf

fontName:lcfont , size:10

I seem to see this a lot... I also see this with the stratagus (WarCraft) engine I\'m trying to run. Is this an SQL library problem? Anyone else getting this?

I looked in the preference, schema, and sprites files (located in /home/QtPalmtop/share/roadmap when installed internally)... but I couldn\'t find anything in these files mentioning a designation trip file to load. How do I get around this?

Thanks in advance!

This is amazing. Thanks for the help guys. I was having permissions errors. The database on /mnt/cf is owned by root. When I run the program as root, it works but I lose the compass. When I run as zaurus, I have the compass but cant access the database. I finally moved all the contents of /opt/QtPalmtop/share/roadmap to /mnt/cf/QtPalmtop/share/roadmap, deleted the roadmap directory in /opt/QtPalmtop/share and created a symlink there to /mnt/cf/QtPalmtop/share/roadmap. Then created a script that basically does a \" export LOGNAME=root \" and \"su -c roadmap root\". I changed the exec entry in /opt/QtPalmtop/apps/Applications/zroadmap.desktop to point to the script and all is working well. It even has voice enabled, i think via flite which I installed last night.

Other questions:
What GPS device are you guys using with this?
Is it possible to set it up so it will tell you to \"Turn right\" etc as you are driving?
How do you plot a trip from origin to destination and have it reflect on the map?

I will be doing some more reading.

Just to make you dream a little about TomTom on your Zaurus.
Don\'t forget to notice that they say that it is running on an embedded Linux OS.

Do you like the difference? On Visual Basic RAD editor, it\'s a simple move + rename for most of those screen (+ gimp work?).

Older versions of roadmap need the default trips file to exist. Try doing a touch or something else to create a (writable, deleteable) zero length file.

You can view maps without a gps. The easiest way to get to a known point is search for an intersection or address.

I\'ve modified mine to automatically unpack BZ2-ed databases from another directory via the download function (unless you want to run boa or something with a CGI script).

Ok, I created an empty \"trips\" file in /mnt/cf/QtPalmtop/share/roadmap using \"vi\". I moved all of the files from /home/QtPalmtop/shared/roadmap to /mnt/cf/QtPalmtop/share/roadmap, and then I deleted /home/QtPalmtop/shared/roadmap. I then created a symlink from /home/QtPalmtop/shared/roadmap to /mnt/cf/QtPalmtop/share/roadmap.

I changed the roadmap icon to run with root priveledges.

...but when I open roadmap I still get the same \"An error occured when opening the selected trip\" error message, followed by the application closing.

Any ideas?

I think it should be in /home/zaurus/.roadmap/trips/default that needs to be created. running \"strace roadmap...\" (2]&1 | grep open) would show you an open that is failing.

i had a boatload of permission errors before I finally got it running. Unfortunately, I could not change permissions on a vfat partition. I moved the roadmaps to an ext3 partition and deleted my ~/.roadmap directories and now can run zroadmap as zaurus user.

TonyOlsen · « **Reply #22 on:** May 17, 2004, 05:34:49 am »

Ok, I created default in /home/zaurus/.roadmap/trips. (It is weird how \".\" directory don\'t show up in \"ls\". Are they Linux\'s hidden directories?)

It still crashes... only this time it doesn\'t actually tell you anything. The icon shows the \"Explosion\" graphic and the hour glass appears.... and then a few minuts later the screen flickers, the hour glass disappears, and that\'s it.

I couldn\'t get \"strace\" working. I will look into it...

Yes, although I think the connotation is more \"housekeeping--don\'t let this clutter up your directory listing\" than \"secret.\"

What error messages (if any) do you get when running it from a shell prompt?

Use ls -a to see everything.

On the side... thanks for the constant flow of good Linux tips... piece by piece I\'m learning this.

Here\'s my output when running this from the terminal:

Code: [Select]

bash-2.05$ cd /home/QtPalmtop/bin

bash-2.05$ ./roadmap

Display size = 480x640

could not open translation file /home/QtPaltop//i18n/zh_TW/libs1/qmid

filename:/home/QtPalmtop/lib/fonts/arial_140_50_t10.qpf

fontName:lcfont , size:10

s## roadmap_locator.c, line 144: cannot open directory database (usdir)

 == roadmap_qps.c, line 232: cannot access GPS source gpsd://localhost

(Above typed manually. Typos may exist)

It looks like the default empty trips file solved part of the problem. It fixed 1 of the 3 errors I get. Am I supposed to have the usdir.rdm somewhere? Is that the main database it is complaining about?

Also... the rdm files I downloaded came compressed in a tarball. I uncompressed them and put the results in the maps directory mentioned above. The documentation says that RoadMap can\'t work directly on the compressed files, so it sounds like I put the maps in the right place. ...did I?

Ethereal · « **Reply #26 on:** May 17, 2004, 03:23:23 pm »

All of my maps are in /mnt/card/QtPalmtop/share/roadmap. You need usdir.rdm and the untarred maps of the state(s) you are interested in. The location of the map database can be changed in File]Preferences]General (tab).

lol! \"Got trouble accessing the Internet? Just go to our website at...\" ha ha ha..

So the default location for the maps ISN\'T in /mnt/card/QtPalmtop/share/roadmap/maps but instead it\'s /mnt/card/QtPalmtop/share/roadmap? I\'ll give that a try.

ChrisZaurus · « **Reply #28 on:** May 17, 2004, 04:02:23 pm »

Did that work? I\'m having the same problem I got rid of the first two messages by creating a vi file default in /home/zaurus/.roadmap/trips, and by creating usdir.rdm in /mnt/card/QtPalmtop/share/roadmap, but i\'m still getting the error:

Quote

== roadmap_qps.c, line 232: cannot access GPS source gpsd://localhost

Do I edit the config file somewhere? I didn\'t see anything about turning off gps in there...

TonyOlsen · « **Reply #29 on:** May 17, 2004, 04:38:38 pm »

I suspect the GPS error isn\'t the problem. I\'m guessing it\'s just saying that it can\'t find a GPS device, which I\'m hoping the software can deal with.

Mine loads now, but I can\'t get a map to load. I said \"Main, Keokuk, IA\" and it gave me a message saying it found 10 matches (for number ranges in the address on the street)... and then it froze up. Had to reboot my Zaurus.

Ironically, I\'m doing more rebooting with my Zaurus that I am with my Windows machine. But that\'s only because I don\'t know how to kill a frozen program... still learning...
