I've found another "bug", with the bookmark.txt (under /home/user/.navit). File is missing (probably need to be created by recording a bookmark). Made a file manually, and the alert disapear.

I think that the original installation of the Gtk library has been badly made (files or folders missing?)

What do you think about it?

gdb is the debugger application. You most probably have no benefit of it. Navit crashed and tried to fire up gdb at the point of code where navit crashed.

I'm using OpenStreetMap here. All the local streets are on the map,but they are not showing up on the search field of the navigator. I even added is_in tags to the streets and it didn't help either.

Fortunately I was able to export OpenStreetMap XML data and edit the tags myself. It seems that, if I move the city center some kilometers to the east, the missing streets are listed now. That did the trick, but sure we cannot move the centers of the cities.

Perhaps the reason to the peculiar behaviour is that the big cities are just beside each others here in the capital area of Finland. Can someone explain, what is the way Navit checks if a street is locates to a city?

I've got the same issue, and then looked inside a XML file. Everything seems to be OK... but, how to convert back an OSM file to a binary?

If I understood you right, that is quite easy to do for a small map. You can install maptool into your N900 and convert the file there. That is what I did.

The command is:
cat map.osm | maptool map.bin

You need to have the city-place definition at the file. Otherwise Navit cannot recognize the city at all.

If you install Navit into your pc, that can be done at the computer, too. Unfortunately, there seems to be an issue when trying to convert a big map to the binary format.

G'day. Here's a more fresh version, svn3048. I made espeak and librsvg2-common as a dependency. Unpack the file somewhere on your n900 and install with dpkg.

Code:

sudo gainroot
dpkg -i /path/to/navit*.deb
apt-get -f install
exit

I did not include any customized xml files yet, so use your own files in /home/user/.navit

Grab the new version here http://rapidshare.com/files/364969894/Navit-svn3048.zip

Nice!

One question: do i need to uninstall the previous version? If so, how to?

@magellan: You shouldn't need uninstall if the previous version is svn3014. This pack should overwrite necessary files, in other words this is an upgrade.

Right... (i'm sorry for my poor english, i'm a french user

)

So... i'v controlled a small XML area, wich is probably contained into the larger map i use. I've checked that the streets are in it, but not seen by Navit in the search process. Then, i've concluded many points:
- The size of the map (.bin format) is signifiant.
- The "city/road" system may have a problem to distinct cities. Many cities are not found because they are certainly "lost" into a large urban area. For example: I want to navigate to "Nanterre", in France. This city is in the surburban zone of Paris, and not seen because of the Paris size.
- I suppose that there's a problem with the "center" concept. If the towns are too close, each town "get" over another, and make them lost each other in the navigation system

These are only ideas... not facts

Cool!

I've asked it because of dependencies. Your new release embedd many libraries, and, carefully (i'm a programer on Java J2EE) i asked myself "what about versions of each library? If new? Replace? If not, no modification, and potentially problems for the navit binary?"

Well... not really stressing step, if it crashs, i'll uninstall the whole components, and gently reinstall everything

Issues by installing (update) the last version:
-> no icon for the app in the software list (in the mobile) : Must execute by the Xterm, no icon left on the desktop.
-> Less crashes (for now)
-> Less errors into the debugging tracks.
-> Same issues as before in the map reading (no identification of cities).

EDIT: Got a strange error: xkbd No such file or directory
