[mkgmap-dev] UBUNTU JVM

Mon Apr 15 07:45:29 BST 2024

Hello, under W10 ,32 GB RAM, Ryzen 7- 8 Core, mkgmap-r4919 (and also
previous versions) stops processing large data sets after about 600
tiles. That's why I installed an UBUNTU 22-04 system. And the
java-1.11.0-openjdk, installs jdk-21-oracle-x64 and jdk-22-oracle-x64
machines.
  None of the JVM works. On java-1.11.0, Ubuntu crashes completely after
starting mkgamp.
Under jdk-21, mkgmap creates ~40 tiles and the terminal exits.
Under jdk-22 mkgmap creates ~40 tiles and the terminal closes.
Which JVM on UBUNTU needs to be installed to fix this error?

Under Windows 10, the generation ends after ~ 600 tiles from 1215 tiles.
Why? What do you have to set up on W10 to make mkgmap work to the end ?

Half a year ago, this went without any problems. Now it doesn't work on
W10 or Linux.
Hints very welcome.
