[gdal-dev] cannot open shape file created in linux in windows

[gaffigan at sfos.uaf.edu]

Xiaodong,

Good morning.  I'm not sure why the example wouldn't work on your machine.
 When I paste the lines below into my linux terminal window, I get the
result shown on the csv driver page.  I tried the example without error on
a number of machines, with GDAL versions ranging from 1.5.0 to 1.3.1.  You
could confirm that the VRT driver is enabled, but I thought it always is.
  ogrinfo --formats     # look for "VRT"

Steve

cat > test.csv <<EOF
Latitude,Longitude,Name
48.1,0.25,"First point"
49.2,1.1,"Second point"
47.5,0.75,"Third point"
EOF
cat > test.vrt <<EOF
<OGRVRTDataSource>

ogrinfo -ro -al test.vrt
