Thanks for the reply
Well, Sailfish is Linux, so grabbing the packaged mapnik and its build-deps for Fedora or whatever should just work. As for Android, it's become such a caricature of what Linux should be that I don't have any idea.

But if the Digia folks were able to run Qt there and Python runs there as well, why shouldn't boost & mapnik fail? But I guess xda-developers may be a better place to discuss mapnik on Android
Overall I think I'll just concentrate on getting one offline map rendering solution going and we will se how to go from that.

Or maybe the pbf (for instance) file could be split into smaller chucks, e.g. 50 MB each depending on the coordinates? And than it would be trivial to get the proper file - take the coordinates x,y - let x1=f(x), y1=g(y) - take the file `map-$x1-$y1` - find the fragment. This would greatly diminish the amount of file reading and RAM used.

Modrana on my N9:
The main page: Nothing happens when clicking on Routes or POI.
Options page: Clicking on POI, Navigation, Network, Debug just bring a black page with just a header of the item. Is there any other files to be installed to make the application useful?

There's this one at VE OS maps: http://talk.maemo.org/showpost.php?p...postcount=1739
Doesn't work on Jolla, I've not recently tried on n900.
Update:
Should be now fixed!

And now for a late release announcement.
modRana 0.52.10 has been released !
The only notable user visible change is the quick routing feature:
Just long press a point of the map and a quick routing menu shows up.
Changelog
The changelog format has changed due to various packaging changes to make modRana packaging more sane & Harbour compatible. The new spec file changelog is now automatically generated from commit message headers and looks like this:
The spec file is now part of the modRana source code repository, so you can now easily check the modRana changelog at any time.
While this is handy for packaging (it is automatically generated!) and for checking which commits are present in which modRana release, this new format is less readable than the "old" hand-written changelog entries.
So I've started writing simple hand written changelogs to the release commits:
As hand-written logs are more readable this will probably be the format of changelogs in future release announcements.

Code:
* Tue Jun 16 2015 Martin Kolman - 0.52.10-1 - Make sure the background bubble stays visible on Sailfish OS (martin.kolman) - Add long-click menu with a "route here" button (martin.kolman) - Set start and destination by a function (martin.kolman) - Add functions for enabling and disabling the routing UI (martin.kolman) - Make it possible to set marker name when appending it (martin.kolman) - Move the pinch and mouse areas under them tile grid (martin.kolman) - Make pan detection HiDPI aware (martin.kolman) - Don't trigger the long-click signal if a pan is in progress (martin.kolman) - Clarify Python 3 support (martin.kolman) - Round position change when panning during pinch zoom (martin.kolman) - Refactor the map marker implementation (martin.kolman) - Add support for long-click detection to the PinchMap element (martin.kolman) - Use rWin.lastGoodPos when computing distance to search results (martin.kolman) * Wed May 27 2015 Martin Kolman - 0.52.9-1 - Make sure that version.txt is present in sourcedir (martin.kolman) * Mon May 25 2015 Martin Kolman - 0.52.8-1 - Create a version.txt file when making the tarball (martin.kolman) * Tue May 19 2015 Martin Kolman - 0.52.7-1 - Only show the keep-screen-on toggle when it does something (martin.kolman) * Sat May 16 2015 Martin Kolman - 0.52.6-1 - More Sailfish Harbour packaging fixes (martin.kolman) * Wed May 13 2015 Martin Kolman - 0.52.5-1 - Remove python3-base dependency on Sailfish OS (martin.kolman) * Wed May 13 2015 Martin Kolman - 0.52.4-1 - Sailfish packaging fixes (martin.kolman) * Tue Apr 21 2015 Martin Kolman - 0.52.3-1 - Fix the Sailfish QML mangling script (martin.kolman) * Wed Apr 01 2015 Martin Kolman - 0.52.2-1 - Initial package
While this is handy for packaging (it is automatically generated!) and for checking which commits are present in which modRana release, this new format is less readable than the "old" hand-written changelog entries.
So I've started writing simple hand written changelogs to the release commits:
Code:
New modRana version 0.52.10
- add a long-click menu to the map for easy routing
- prevent the route from wobbling during pinch zoom

Does 0.52.10 include the VE OS maps fix? I still can't seem to get it to download - though I'm perfectly willing to accept it's pebkac issue.

In any case if you clone modRana from GitHub it will have the fix and should run out of the box. If you are using it on the N900 just run modrana.py from the command line. On Sailfish OS you can use the run/sailfish startup script.

If a need comes up, I'll look into cloning it, but I'm busy with wrapping up one job and hunting for another at the moment. I hope to have some time to play more with less standard stuff on SFOS when the tablet arrives and I have a bit more time.

Two questions:
1) Do normal map tiles 'expire'? It'd be ideal if the app could check whether tiles were up to date if they're older than a certain age and still being used, though if that isn't possible just having an option to flush them after a year or so would be good.
2) Don't copy-on-write filesystems have terrible performance for databases? I read older versions of BTRFS were notorious, and Sailfish has an oldish one...
I'm wondering whether creating a subvol without COW for the maps, or perhaps just tuning down the write frequency massively in the config file might help performance (not sure I'm brave enough to try the former - and I'm certainly not suggesting anyone else should, unless they know what they're doing...)
Love the app, but hitting some weird problems on sqlite where it seems to refuse to load tiles it has clearly loaded before. Still, I realise it's early days yet for the port. I'll try to capture some debug output if I can.
(p.s. sorry if these have been answered. I read 20 - 30 pages of the thread, didn't see anything)

This is a log from when the database seems to 'lock up', apparently refusing to load tiles it has already downloaded. I'm not 100% sure how to trigger it, but generally scrolling around and zooming in and out in an area I haven't yet downloaded works reliably eventually. I've left it in that state for 1/2 hour probably, and it doesn't recover - though interestingly, it does seem to be able to load other tiles sometimes (e.g. if I zoom really far out) - it just seems to choke on certain particular areas of map, but after closing the program and relaunching it, and sometimes even just by zooming out then back in again, those areas of map will draw fine.

Quite a few examples of this:
And probably less important, but nevertheless rather saddening to read, this too:

Side note:
Due to a bug, it seems it's currently impossible to send the logs via the Jolla mail client using gmail, unless you rename them (removing the #).
