Re: Navit GPS (and libgarmin) for os2008

I have also successfully routed from Akron, OH to Toledo, OH using the Town interface. From my location to Toledo center. I travel frequently into Indiana, but am unable to route to towns there. I believe there are some errors on Route 80 that prevent the route from completing. I also just routed from Indianapolis to Valpariaso, IN using only the Town feature to select my position and destination. I am currently using OSM from cloudmade for Ohio and Indiana.

I did install the libgarmin build from earlier in the thread, but get the same error you do: invalid map type.

Thanks for letting me know that it does work. there is someone local to me that it works for as well so OSM for my area should be fine. Just have to figure out why .....

Re: Navit GPS (and libgarmin) for os2008
 

dwould (or anyone else) I saw you were using the announcer_toggle button in your modified osd. Do you have a speaker that shows up in that box? I just get a small question mark.

I was looking through the xpm folder and saw several gui_sound_off and gui_sound png / svg files with different sizes. Last night I was digging through the svn files and found gui_sound_off.xpm and gui_sound.xpm (svn1960). Don't know why they weren't installed on my N800. Copied them into my /home/usr/navit/xpm folder and presto a nice little speaker in my announcer_toggle box.

Just wondering if I should uninstall/re-install and if I may be missing other things as well.

Hi
I posted a file of pre-built icons on my blog. That is a place holder until they get built in the SVN builds. Presently the nav and flag icons are svg, which N800 doesn't like to scale.
And once I build my temp release (will post on blog), you will ge tto see large improvement in menu speed due to implementing trac 284.

with flag icons in place, you can see your default country. And if that default is wrong, you can fix it. [edit] mnnm there are issues with that approach, adding an additional locale is more complex...

Which maps are you guys using? Could you please confirm wherever I can use the maps purchased for Garmin Mobile XT with Navit GPS?
thanks!

Re: Navit GPS (and libgarmin) for os2008
 

Hi
Generally we use maps from OSM although Garmin format ones can be used, except those that are locked. And that means locked even if you have the key. There were/are Garmin Metro Guide files that are not locked, those probably work, but those do not support routing (even with Garmin devices).

The Navit wiki has further details.

Hi,
I just tried Gerrit's fix for menu performance. and WOW it makes a huge difference to the speed at which the menus work.
Thank you Gerrit!

Inspired by this I had a thought and compiled navit with -O2 in the CFLAGS (basically switch on all the compiler optimisations) Now my feeling is that this has done wonders for the performance I'm seeing. Though I've not yet had a chance to use it in anger, I was able to set a route and move the map about, zoom in/out etc much more responsively than I felt I had before.

I shall switch back now to regular version and see if I can quantify a difference, or see if it's just me being optimistic. Anyone else care to try compiling with optimisations and see what they think... Gerrit?

Re: Navit GPS (and libgarmin) for os2008
 

I don't have a compiler setup or particularly have time to learn (and include the diffs) right now, but I'd love to give it a try and give feedback.

Re: Navit GPS (and libgarmin) for os2008
 

Ok here is a deb compiled with Gerrits' changes and the optimisation flag set.
I'm still not sure if the optimisation flag is having an effect. Comparing against a regular build without Gerrits change is a massive difference in overall responsiveness, but that maybe purely Gerrits change. I've not had time to recompile without optimisation to compare just that difference.

Anyhow here you go : http://demigoth.org/files/navit.tar.gz

I tried to attach it here, but it's too big for the file limits. So it's hosted on my server, for want of a better file sharing option.

Re: Navit GPS (and libgarmin) for os2008
 

Hi dwould,
I think the benefit is additive!!!
Simple way to do this is is add CFLAGS="-O2" to the ./configure line (along with the other necessary params), then 'make clean all' or build the .deb file. This replaces the defaults CFLAGS="-g -O2"
(I forget how -g and -O2 interact, I vaguely remember -g reducing the optimization but that was from my 1990's Unix work...)
