Hi In investigating another problem I discovered that an index created for tiles in Greece (and it would also apply to any other place where non-latin letters are used) does not work for finding streets. You can select them but clicking on Find usually does not find them. This is because the transliteration from Greek characters to Roman characters occurs after the labels are sorted for the NET section. This results in them being completely mis-sorted in NET. The attached patch does the transliteration first. It doesn't much affect maps of western European countries, but it would be good to get wider testing before committing it. Maps with ascii labels are sometimes a little smaller, because name that are different but transliterate to the same string used to be duplicated but with this patch they are not. ..Steve
Steve, I tested the greek_index patch patch only. I assumed it was an alternative to the translit_first patch. Was it? Or should it accumulate? First thing with the greek_index patch, should be to add the forceUppercase()-method definition to the Transliterator interface to be able to compile the src. public interface Transliterator { ..... public void forceUppercase(boolean uc); } BTW: I'm proud I finally got Eclipse, SVN and the jdk toolchain running! ;-)) Second, we now have a kind of "differentiated" mapsource behaviour. - pan and zoom: OK - select tiles: OK - idx creation: OK now with all tiles - map aggreg. : OK with a few tiles CRASH with a few more tiles ERROR with many tiles Here are the figures / messages of my tests: #tiles est.Size Message / Error 619 3,72 GB Size of mapset ca. 3810,3 MB, on SDCard only 7781,8 MB available. Try again with fewer tiles. 456 2,74 GB Size of mapset ca. 2806,3 MB, on SDCard only 7781,8 MB available. Try again with fewer tiles. 216 1,2 GB Size of mapset ca. 1230,8 MB, on SDCard only 7781,8 MB available.

Seems like Mapsource's book-keeping of mapsizes got a little bit out of sync with the patch. With a few less tiles we trigger another TRIM-error in mapsource. It changed from ADDR to SC(?). MDR_TRIM_ADDR.CXX-440-6.16.3.0 -> MDR_TRIM_SC.CXX-808-6.16.3.0 Only with very few tiles (#29 in my test) I could transfer the map to my SD-Card. Peter Am 31.05.2011 15:14, schrieb Steve Ratcliffe:

I uploaded the mapsource tmp file when the error was triggered to http://files.mkgmap.org.uk/download. 00006324.MDR Mapsource temp MDR file in ..\AppData\Local\Temp\MapSource\GdxIndexBuilder when MDR_TRIM_SC.CXX-808-6.16.3.0 was triggered. I hope it helps track down the problem. Peter

I could successfully transfer 596 tiles with a total of 3,67 GB -- excluding Balkan states and eastwards!! That means greek and cyrillic(?) letters are still a problem ... despite the current greek_index patch. Peter

No, greek_index is a simple patch, which although it seemed to help doesn't really deal with the major problems that existed. translit_first is a separate patch and will fix a lot more things. Sorry if that was not clear. ..Steve PS

I've often seen that message, just assumed that Mapsource was confused somehow and the problem would go away reattaching the SD card. But if you have a reproducible case where this is not true let me know.
