[mkgmap-dev] Find Address - No cities

Sat Jul 29 16:09:03 BST 2017

Hi Gerd

I've done a bit of investigation and debugging. It seems to be building
the indexes with enough cities and streets. MDR20 is the suspect index.

I'm now experimenting with mkgmap / Display

With just the suspect map built in gmapsupp:

$ ... test.ExtractFile gmapsupp.img

seems fine but

$ ... test.display.MdrCheck 00007444.MDR
---------- 00007444.MDR --------------------
EXTRA

# reading 74440044
mdr5 check

+ exit

On another map from the split this runs OK, producing masses of output:

$ ... test.display.MdrCheck 00007429.MDR
---------- 00007429.MDR --------------------
EXTRA
remaining {}
# reading 74290047

2 map1; ABRIDGE mapCity=3 reg=0 (ESSEX) country=0 (UNITED KINGDOM^]GBR)
ind20=0 rep=false
... 87000 more lines ...

Do you think mkgmap:Display is finding a real problem and I should
pursue this line, or could it be unreliable and this exception is due
to it rather than the format of the index?   

Thanks
