Here I am, it seems that trunk is working. I didn't obtain segfault anymore. But now the import (to a new location) doesn't works for me. I did the same as in the previous release versione, even changing dns to input. I will investigate more. 2015-02-18 22:14 GMT+01:00 Anna Petrášová

Re: [GRASS-user] Is the location's VAR file required?

I confirm that trunks doesn't causes segfault. Same mapset and location. Now I have to figure our why the import doesn't happen: v.in.ogr input=/mnt/data/centroids.shp location=workLocation output=centroids -ie The location is created but is empty. Thr same shape is correctly imported from GUI.
