[Gdal-dev] unable to initialize OGR datasource using C#

[Tamas Szekeres]

Eduardo,

I think some of the dll-s could not be loaded by your application. I
guess you should strip the '_fw' suffix of some of the dll-s in the
FWTools bin directory if you don't have those dll-s available on you
system. For example try to rename proj_fw.dll to proj.dll and so on.

Best regards,

Tamas Szekeres
