ich have on my 64 bit Windowsmachine and 5500 MB for java no problem. I also
use the geofabrik europa-extraxt; aktually ~ 16 GB osm.pbf. 1. step : Splitter
creates ~ 570 <name>.osm.pbf files and as 2.step mkgmap makes the img-files.
But in this 2. step i create not a <name>_mdr.img ! As 3. step i run mkgmap
with this options : --index --tdbfile --area-name=Europa *.img. I never
create a gmapsupp; only PC -Installation. This method has additionally
advantages: you can create many country-spezific-maps with option --index
--tdbfile --area-name=Poland poland*.img

6GB for Europa? I use the extract "Europa" from the geofabrik. With my style a
12GB Machine failed.
I make a Test with the "Balearen". With my style the mdr-file has 6,5MB. With
the default style only 5 MB.
In my style some ways exists more than one time. For example a street with
surface=cobblestone. There are 3 lines, one invisibel for routing, one for the
look and one for a marker, that the surface is bad.
Is it right, that only lines with highway=* use for adresses? Perhaps its
possibel to use only one highway Tag for the ways and for the other infos i use
a custom word.
Why it is necessary that the mdr build in only one step? Perhaps it ist
possibel, that this run a few rounds.

Hallo Arndt, ich nutze einen PC mit 6 GB RAM, und weise in der Commandline zum
start von mkgmap java 5500MB zu .Damit mit kann ich den europai_mdr.img
erstellen. Habe aber die x-splitt-name-index nicht benutzt. Auch die
gmapsupp-option nutze ich nicht.

Reg. memory: If you have a 64 bit system it is probably better to buy more
memory. I think Steven did already
try to reduce the memory usage so I guess there is not much room for
improvements.
reg. city index: I assume it is possible, not sure if it makes sense.
I guess you have names like "Samtgemeinde Harpstedt" instead of "Harpstedt" ?
In that case I think it would be better to use subst like we do for
"Gemeinde".
Do you have positive examples ?

Betreff: [mkgmap-dev] Index with little ram?
Hello together,
mkgmap needs a lot of RAM to build the index for the adress search. Also for
the gmapsupp.
My computer has 4 GB and it´s not possible to build the index for a germany
map. It works, when i not use the "x-split-name-index" Option. But I want to
use this.
The map has 2,21GB (only the mapfiles)
The Computer from my son has 12 GB. This machine has no problem with germany,
but failed, when it builds the index for an europe map (12,1GB).
Is it possible to change the index-build process so, that also a little
computer is able to build the index?
By the wy, the x-split-name-index works fine by street names. Is it possible,
that it also works by town-names?
Best regards
Arndt
