Hi Andrzej
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.
There is a default for levels: DEFAULT_LEVELS = "0:24, 1:22, 2:20, 3:18, 4:16" There is not a default for overview-levels, although an overview level is constructed based on the highest level in 'levels'.
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=".
OK.
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.
Oh I see now. In case 2 the highest level is 1, whereas in 3) the max level is 2, since the normal and overview levels are combined. I can change this so that a level 2 would translate to the resolution of the level less than or equal to it. ..Steve
