Hi Gerd, I have tried to compile South America and tripped on another crash. This is version 4065, it crashes regardless if HGT is present or not. http://files.mkgmap.org.uk/detail/395 java.lang.ArrayIndexOutOfBoundsException: 5 at uk.me.parabola.mkgmap.reader.hgt.HGTConverter.getElevation(HGTConverter.java:91) at uk.me.parabola.mkgmap.reader.hgt.HGTConverter.getHeights(HGTConverter.java:308) at uk.me.parabola.imgfmt.app.dem.DEMSection.calcTiles(DEMSection.java:128) at uk.me.parabola.imgfmt.app.dem.DEMSection.<init>(DEMSection.java:74) at uk.me.parabola.imgfmt.app.dem.DEMFile.calc(DEMFile.java:61) at uk.me.parabola.mkgmap.build.MapBuilder.makeMap(MapBuilder.java:322) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:107) at uk.me.parabola.mkgmap.main.MapMaker.makeMap(MapMaker.java:69) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:263) at uk.me.parabola.mkgmap.main.Main$1.call(Main.java:259) at java.util.concurrent.FutureTask.run(Unknown Source) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at java.lang.Thread.run(Unknown Source) Exiting - if you want to carry on regardless, use the --keep-going option -- Best regards, Andrzej
