Hi Steve,
I don't understand this. If you have no --levels option then the default should be used, which has a maximum of 4.
Looks like there is no defaults now, or maybe only level 0 gets a default resolution.
What do you think that the message text should be?
Maybe something like "'level 1' is used in style while its resolution is not defined in option 'levels=' nor "overview-levels=".
What are the conditions to cause this error?
My previous analysis was wrong. This is what I'm doing: - I have modified default style changing some "resolution xx" to "level 0", "level 1" or "level 2". - I have commented "levels=" and "overview-levels=" in "options" file. Now I run compilation with following command line options: 1) --levels=0:22,1:21,2:20 --gmapsupp --no-tdbfile 2) --levels=0:22,1:21 --gmapsupp --no-tdbfile 3) --levels=0:22,1:21 --overview-levels=4:16 --gmapsupp --no-tdbfile Compilation 1) goes correctly. Compilation 2) ends with an error. Compilation 3) creates a map. Map for case 2) consist of only layer 0 and 1, so all references to "level 2" in style could be ignored. I would expect successful compilation at case 2). Next observation is that case 3) shouldn't be different from case 2), there is no definition for "level 2" either. -- Best regards, Andrzej
