Hello,

should work as Ticker says: --input-file=./otm-hungary.img

> ...but I thought I can merge multiple IMG files into a single one with Mkgmap.

AFAIK you can. Just keep an eye on the typ-files, that is: use identical ones.

Subject: [mkgmap-dev] Trouble with merging IMG files (for Garmin)

Hi You need to have ... --input-file=otm-hungary.img ... to fix the file doesn't exist errors. I have no idea if the rest of what you are asking for will work. Ticker On Thu, 2023-07-13 at 16:35 +0200, Tamas Gal wrote:

Hi all, maybe I got that wrong but I thought I can merge multiple IMG files into a single one with Mkgmap. My problem is that I need a bunch of maps and my Garmin 64s only shows 12 in the map selection. A simple solution to this limitation is merging maps ;) Anyways, I gave Mkgmap a try but I get an error which I don't know how to interpret, since it's missing the input files but they are definitely in the folder. Do I maybe need the original OSM files as input files? In that case, the error message is probably wrong. Here is an example where I try to merge the Hungarian and German map into a single IMG: ░ tamasgal@silentbox:~/opt/mkgmap-r4909 ░ 16:29:24 > ls -alh *.img -rw-r--r--@ 1 tamasgal staff 126M Jul 13 16:24 otm-germany- contours.img -rw-r--r--@ 1 tamasgal staff 43M Jul 13 16:28 otm-hungary- contours.img -rw-r--r--@ 1 tamasgal staff 346M Jul 13 16:28 otm-hungary.img -rw-r--r--@ 1 tamasgal staff 246M Jul 13 16:29 otm-slovenia.img ░ tamasgal@silentbox:~/opt/mkgmap-r4909 ░ 16:29:32 > java -jar mkgmap.jar --input-file otm-hungary.img -- input-file otm-slovenia.img --gmapsupp Mkgmap version 4909 Time started: Thu Jul 13 16:29:45 CEST 2023 SEVERE (Main): : input file '' doesn't exist WARNING (global): Setting max-jobs to 1 SEVERE (Main): : input file '' doesn't exist Number of MapFailedExceptions: 0 WARNING (global): To reduce the run time, consider increasing the amnount of memory available for use by mkgmap by using the Java -Xmx flag to set the memory to more than 32800 MB, providing this is less than the amount of physical memory installed.
