Best thing would be to try it out.
- availability of zoom levels depends on the server (terraserver-usa responds to most of them - others only to certain levels)
- file sizes are more in the range of satellite maps (as lots of maps seem to be hand drawn, compression doesn't work that well - may be the image/jpeg format leads to smaller files)
- currently the most annoying thing is the terraserver-usa behaviour - may be it's possible to add some pauses, when downloading?
- 'proj' should be ready for installation (no graphics!)

Hiking in the Bavarian Alps with these maps worked fine for me!

Regarding gconftool:

I tried it as root and as 'user'. Still getting the segfault. I'm not going to reflash my 770 though, it's such a pain in the butt to get all the little settings and apps back on it. I'll sit back and wait until things become more stable.

BTW, there is no /apps/maemo or even /apps on my machine, so maybe that has something to do with it. And I have no idea what 'gconftool-2' is! Does anyone know the directories/files that are involved in the mapper settings? I'd be happy to delete them by hand rather than trying some script or tool to do it - gconftool doesn't give any feedback.

gconf is the Linux equivalent of the Windows Registry - it's a hierarchical set of configuration data that can be read and written programmatically.

gconftool-2 is a command-line interface for interacting with gconf. use "gconftool-2 --help" for more details, or google about it.

"/apps/maemo" is a name for a gconf key, or, in this case, a key "directory", which is like a container for keys. It is analagous to a directory structure in a file system, but it doesn't correspond (directly) with the file system.

"/apps/maemo" is the key directory in which all maemo applications should place their gconf preferences. "/apps/maemo/maemo-mapper" is the "key directory" in which Maemo Mapper's gconf preferences are placed. You can use the following command to list the keys in the maemo-mapper key directory:

gconftool-2 -a "/apps/maemo/maemo-mapper"

If you run that command after running maemo mapper, it should give you a list of key names and values. Except that if Maemo Mapper crashes before it can save keys, it won't get a chance to create any keys in that key directory, so the directory will remain empty.

So, pdafan, if you would induldge me, what is the output of the above command on your Nokia 770? If it is non-empty, then please PM to me the output.

If it is empty, then I conjecture that there is something unique about your Nokia 770 that is causing the problem. Have you done anything special to your particular Nokia 770, like apply a special theme or use a unique locale? Have you done anything funny with root, like move directories around, or move/delete the /home/user/MyDocs directory or any of its subdirectories?

I'd really like to work with you to discover the problem, because if it _is_ a bug in maemo-mapper, then it might affect other people, and of course I'd like to fix it. If you prefer, we can continue the dialogue in private - just PM me at your convenience.

This my story.

All versions 1.0 - 1.2.3 worked without issues up until early this week.

Then my tablet decided it wouldn't boot so I had to reflash.

I reinstalled some applications (FBReader etc) and installed 1.2.3.

Received the segmentation error.

Backed out to version 1.1 and have no issues with that version.

This is my gconf-2 output when used with 1.2.3

(used the Notes app on the Nokia..forgive the spaces)

/apps refers to /var/lib/gconf/apps

go to /var/lib/gconf/apps/maemo/maemo-mapper and rename (mv) %gconf.xml to old%gconf.xml and try again.

Hi
I am sorry to say, but I get Segmentation fault with v.0.12.3 even after renaming first /var/lib/gconf/apps/maemo-mapper/%gconf.xml and later the dir /var/lib/gconf/apps/maemo-mapper/. apt-get (remove|install) maemo mapper did not help so.

Old binary runs in any case opening the configuration dialog box. That after removing old conf data.

The v. 0.12.3 crashes before opening any window.

Edit: the old binary crashes immediately after confirming the configuration. BTW upgrading the package some libs was also upgrded to a new version.

BRs,

I think an older version (1.0?) of maemo-mapper used /var/lib/gconf/maemo-mapper
You should delete that directory.

The later versions use /var/lib/gconf/maemo/maemo-mapper

Since 1.2.3 seems to work fine for everyone else, maybe there's a conflict with some other application you have installed.

Hi,

I have the same problem with the new version 1.2.3 of maemo-mapper. It's crash with segfault. Any hints to solve the problem ? Version 1.2.2 run with no problems.

After having deleted the old parameters and with version 1.2.3 all running fine here, also with /dev/rfcomm0 trick.

Thanks for the update!

To everyone who has cleared their configuration and is now getting a segfault on startup with Maemo Mapper v1.2.3: please try typing the following commands (exactly as they appear - use copy/paste) into an xterm.
Then try starting Maemo Mapper. Let me know if this has any effect.
