[gdal-dev] OGR: Accessing ESRI Personal Geodatabase on OS X

[Carlo A. Bertelli (Charta s.r.l.)]

Hello,
maybe a solution may be found at a lower level, using gdal java
bindings with Jackcess (http://jackcess.sourceforge.net/), the library
behind mdb-sqlite. This could be a simpler solution for all platforms
besides Windows.

I have not been able to get this working on OS X with the system iODBC (I last looked at it a year ago).  It compiles (with some hackery), but does not load.  I haven't tried mdbtools with UnixODBC, mainly because I prefer to use stuff available from the system, and UnixODBC is a large project.  Maybe if I can whittle it down to a bare minimum needed for mdbtools (and assuming it works), I could bundle it in the GDAL framework.

This wouldn't mirror the pgeo driver exactly as a feature (requires a separate external step), but it's _something_.
