[gdal-dev] shp-gpx conversion with ogr2ogr

[flavio rigolon]

Hi all,
 I'm trying to convert a SHP file to GPX via ogr2ogr.

The "default" conversion works well:

<http://www.gdal.org/ogr/drv_gpx.html>$ ogr2ogr -f GPX nome_file.gpx
nome_file.shp

I'd like to mantain two attributes and I tried the option
GPX_USE_EXTENSIONS=YES with sql instruction to rename the interested fields:

$ ogr2ogr -f GPX -dsco GPX_USE_EXTENSION=YES -sql "SELECT NOME AS name, CAT
AS desc FROM source_layer" nome_file.gpx nome_file.shp

but I get this error:
--------------------------------
ERROR 1: SQL: Missing comma after column NOME in SELECT statement
--------------------------------
It seems that I forgot a comma but this command is the same in the
documentation.

I've checked the syntax with the help of this doc:
http://www.gdal.org/ogr/drv_gpx.html
http://www.gdal.org/ogr/drv_vrt.html

but I don't understand where is the error.
Does anibody have similar experience?

Thancks a lot for any hint.
