Hello @all
</div>
<div>
</div>
<div>
my PC is not he best machine. 4GB RAM & Intel CoreDuo 3GHz 64bit Win7.
</div>
<div>
</div>
<div>
Making maps from Europa is no problem, but at the end of the process, mkgmap failed to build mdx/mdr.
</div>
<div>
</div>
<div>
For the website www.speichenkarte.de i need germany and a few kilometers more. Size of the files after "splitter" is 2,8 Gb and 213 img-files.
</div>
<div>
</div>
<div>
mkgmap 3426 is to be able to build this.
</div>
<div>
</div>
<div>
mkgmap 3472 failed to build mdx/mdr. Also the gmapsupp dosnīt work/no shown.
</div>
<div>
</div>
<div>
Need 3472 needs more computing power than 3426?
</div>
<div>
</div>
<div>
Is it possible change mkgmap, to create mdr/mdx and gmapsupp wiss less cumputer power?
</div>
<div>
</div>
<div>
Best regards
</div>
<div>
Arndt
