using gdal/ogr with epd

August 12, 2009

I had to add the gdal and ogr libraries to a fresh EPD 4.3.0 Windows install. Here is how i’ve done and what were the problems encountered :

  1. Install the python module : easy_install gdal
  2. Add the dll libraries : Download and uncompress to c:\gdalwin32-1.6 from
  3. Update your path

This is were you had to manually do some updates. I haven’t exactly found the culprit but there is a problem with the OpenSSL dynamic libraries (libeay32.dll and ssleay32.dll). There is one version in c:\Windows\System32, one in c:\Python25 and one in c:\gdalwin32-1.6\bin directory.

If you do not update the path, you get the following error when loading ogr :

The ordinal 3873 could not be located in the dynamic library LIBEAY32.DLL

and the library cannot be loaded.

Just put your c:\gdalwin32-1.6\bin\ directory on the first place in your path :


Hope this will help.
