gpsbabel fails to open some files

[Alister]

I don't know what is distinctive about the attached file, but the gpsbabel included in osgeo4w does not open it. The easiest way to demonstrate is using ogrinfo.

If I replace the osgeo4w gpsbabel executable with the one from the windows installer on the gpsbabel site, it works.

Thanks for the problem report Alistair. Would you please provide some more details? For example what command(s) are failing, and what errors are reported.

And how does ogrinfo help demonstrate the issue? Ogrinfo doesn't understand the Garmin Mapsource .gdb format.

Ogrinfo understands it here :)

With the osgeo4w gpsbabel:

$ ogrinfo problem.gdb
ERROR 1: [gpsbabel error] gdb: Unexpected end of file ((Memory stream))!


FAILURE:
Unable to open datasource `problem.gdb' with the following drivers.
  -> ESRI Shapefile
  -> MapInfo File
...

With the gpsbabel executable from the windows installer:

$ ogrinfo problem.gdb
Had to open data source read-only.
INFO: Open of `problem.gdb'
      using driver `GPSBabel' successful.
1: tracks (Multi Line String)
2: track_points (Point)

I have a couple of other .gdb files here which do work with the osgeo4w gpsbabel. They each have one point layer and no line string layers, so possibly the gpsbabel in osgeo4w doesn't understand .gdb files with multiple layers, or doesn't understand linestring layers.

Ah, that helps. I can confirm the error on my system now. It turns out that if the gdal-filegdb package is installed ogrinfo never tries to use the gpsbabel format:

>ogrinfo problem.gdb
ERROR 1: Error: Failed to open Geodatabase (The system cannot find the path specified.)
ERROR 1: Error: Failed to open Geodatabase (The system cannot find the path specified.)

What does the working gpsbabel -V report on your system? (osgeo4w is 1.4.2)

[Alister]

$ gpsbabel --v
GPSBabel Version 1.4.3-beta20111112
...

If you want I can try their 1.4.2 build, to check if that works too. Might not get to it until tomorrow though.

=================================== I can't see a gdal-filegdb package. Is there some sort of testing repository with it? Or have you just built it yourself?

I've push a fix in GDAL in ​http://trac.osgeo.org/gdal/changeset/23478: "FileGDB: only try to open .gdb directories, not file (http://trac.osgeo.org/osgeo4w/ticket/245)"

If you want I can try their 1.4.2 build, to check if that works too.

Yes, it does.

Curious that it works for you, it doesn't for me.

No, it's in current: ​http://download.osgeo.org/osgeo4w/versions.html.
