[GRASS5] Problem with shapefile

[Virgilio Gómez Rubio]

Hi all,

It's been a long time since we met in Trento, isn't it?

I am writting because I have a problem when timporting a shapefile.
What happens is that some lines (and ares) are lost. The command line
and error message I get are:


GRASS:~/tmp > v.support option=build -r map=cod_munici
err=err_cod_munici

V.SUPPORT:

I think the problem is related to that unclosed areas, but it is also
true that ArcVIew reads the shapefile without problems.

Any idea?

Of course, if some developer wants to try the shapefile I can send it to
him/her.

Regards, thanks and best wishes,
