gosmore rebuild segmentation fault

Alwayforver · 2012-08-10T00:35:47.000Z

Rebuilding without bounding box works well, but after that when I’m trying to create a smaller .pak file by specifying a cropping bounding box :
mv gosmore.pak master.pak
bzcat …osm.bz2 | ./gosmore rebuild l1 l2 l3 l4
it gives “Segmentation fault (core dumped)”.

I have enough virtual memory and cannot figure out what’s wrong…

Anyone knows how to solve this?

Maybe some hints can be found on http://help.openstreetmap.org when you do a search there for “gosmore” … there are already some topics about rebuilding.

Or any hints at the OSM wiki about gosmore.

This was caused by a bug in gosmore code. After successfully doing rebuild, the program falls through to presenting the Gui.
It was then it crashed to an error in the code.
I was only noting this as I hit the same snag recently and it irked me.

#ifdef USE_GPSD
gps_data_t *gpsData;
gps_open (“127.0.0.1”, “2947”, gpsData);
if (gpsData) {

Compile warning

jni/gosmore.cpp:3488:12: warning: ‘gpsData’ may be used uninitialized in this function [-Wmaybe-uninitialized]
gps_open (“127.0.0.1”, “2947”, gpsData);

(e.g. should be gps_data_t *gpsData = NULL;)
