How to configure offline map viewer for openstreetmaps on debian?

I've installed Gosmore and was going to download some maps in osm.bz2 format from here . How can I add them to Gosmore? I was googling but didn't manage to find any solution, so I'm not sure if I will manage to make it work or not. Maybe there is another good solution for fully legal free offline maps? **Update**: tried using command bzcat /file_location/filename.osm.bz2 | gosmore rebuild Got some errors (no any icons found) and then 1 while (xmlTextReaderRead (xml) == 1) and nothing happens. Maybe that is so because I installed gosmore from Debian repository, I'll try the way it told in official documentation (though it told that I CAN install from Debian repo). **Update:** Tried manual installation - the same result. Gave up with gosmore, tried to configure navit, and it doesn't work as well, I see no maps - only rose screen, it seems like maps just not loaded. I found a solution for the same problem on official maillists , but the solution provided did not work for me. **Update** I think I found quite good solution, see bellow.
