[GRASS-user] v.in.ascii don't work

[Manuel Francisco Maestre Páez]

Maybe a problem with gdal libraries. Has v.in.ascii worked some time? or
never worked?

Hi,

I check for spaces on columns, misllaneous character, etc. The text file
is clean.
I also check the bounadries of my region settings and it's ok, the
points are inside it.
I just produced a CSV file from a spreadsheet, and still not work.

How to know what happend durin v.in.ascii execution (debug or a log file) ?

Regards
