= ArcSDE = 

Use of the [http://www.gdal.org/frmt_sde.html GDAL] or [http://www.gdal.org/ogr/drv_sde.html OGR] ArcSDE drivers requires building GDAL/OGR with the ArcSDE client libraries. These are obtained from ESRI, normally on the SDE product CDs or perhaps as part of developer kit.  It is not normally available for free. 

== Building on Linux ==

On linux this is specified something like:

{{{
  ./configure --with-sde=/home/gdal/ArcSDE-10.0 \
              --with-sde-version=100
}}}

Note that the directory specified to --with-sde should have subdirectories "etc", "include" and "lib".  The version is the version number multiplied by 10, so ArcSDE 9.3 would be "93".
