[mkgmap-dev] Find Address - No cities

From Gerd Petermann GPetermann_muenchen at hotmail.com on Sun Jul 30 07:33:33 BST 2017

Hi Ticker,

hmm, I think the patch looks good and I have no idea why the search doesn't work
for you. Yesterday I thought the patch handles the overall number of cities in the gmapsupp,
but it is about the number of cities in a single map tile.
Maybe there is another problem caused by the high number of cities. Maybe you can post a link to the tile with
that high number?

Gerd

Hi Gerd

Quite possibly, or maybe there are limits in the device.

More testing reveals that although my lists of cities and streets
within them appear correctly in Find>Address, it doesn't find anything.
