[mkgmap-dev] Reproducible Problem With Generating gmapsupp.img

Thu Dec 4 18:41:04 GMT 2008

Hi,

I have a problem generating gmapsupp.img. I can reproduce this with some 
simple steps. The file is generated but it doesn't work on GPS units. 
This happens with multiple versions of mkgap. I'm sure I am doing 
something wrong, but I don't know what.

1. Download and unpack the set of Computer Teddy Germany img files from:

   http://openstreetmap.teddynetz.de/latest/deutschland.tgz

2. Download and build latest svn HEAD of mkgmap or get latest version from:

http://www.mkgmap.org.uk/snapshots/mkgmap-latest.tar.gz

$ java -Xmx512M -jar ../../mkgmap/mkgmap.jar --version
735-svn

Note: this is actually the latest svn HEAD version as of December 3rd - 
not sure the reported version number is correct.

Note that this problem occurs in older versions as well (744 and 587 for 
example).

3. Save the attached mkgmap.opt, which lists all the Germany tiles.

4. Run mkgmap with something like:

$ java -Xmx512M -jar ../../mkgmap/mkgmap.jar -c ./mkgmap.opt

No errors, no output, gmapsupp.img is generated:

$ ls -l
total 238236
-rw-rw-r-- 1 andy webdevelopers    104960 2008-12-04 10:55 63240000.img
-rw-rw-r-- 1 andy webdevelopers     13233 2008-12-04 10:55 63240000.tdb
-rw-rw-r-- 1 andy webdevelopers 243656718 2008-12-04 10:56 gmapsupp.img
-rw-rw-r-- 1 andy webdevelopers      5497 2008-12-04 10:54 mkgmap.opt
drwxrwsr-x 2 andy webdevelopers      4096 2008-12-03 22:49 tiles

5. Copy gmapsupp.img to a GPS unit. The map is not used. This is 
confirmed on a 60CSx and Colorado.

Any ideas on how to solve this?

thanks, Andy
