[mkgmap-dev] Memory problems since 1245

Mon Oct 5 08:52:04 BST 2009

Hi,

I don't know where to post a ticket, but I'm sure you'll tell me if it's
the wrong forum.

Since version 1245 I had to increase the memory size in the MkGMap
command line

 and the virtual memory of my machine to get mkGMap to work.

(1245 was the last version I could get to work, but with the -index
switch off)

What am I doing wrong or is my hardware just too small?

Did anyone else experience a large increase in memory resource usage
since MDR & indexing was introduced?

I have not been able to test the results of the new dev around indexing
yet, because I am not able to compile a map

to send mapsource. It takes 3 hours to compile with these errors, so I
can barely run 2 tries per night. 

If someone can save me time with some tips, I will sincerely appreciate
it.

java -ea -Xmx1300M -jar mkgmap-mdr-r1257.jar (if I increase Xmx java
cannot create VM (whoever that is))

 --name-tag-list=name:af,name

 --route --remove-short-arcs

 --road-name-pois (I need this to search streets on device, but I can
remove it & build a separate map for the device if is the cause of the
problem)

 --tdbfile

 --style-file=MyStyle

 --description=01000000

 --product-id=0001

 --overview-mapname=SdAf1T1246 (should have been 1257 this time, but
will not have an effect)

 --mapname=10000000

 --family-name=GeoSdAf1T1246 (should have been 1257 this time, but will
not have an effect

 --family-id=0001

 --Region-name="SARegion"

 --generate-sea

 --ignore-osm-bounds   (If I don't use this the land & sea is reversed)

 --index

 --gmapsupp
