I'm just looking for some clarification on a question that came up with me this morning. Are the DLL client files (libeay32.dll, libiconv-2.dll, libintl-8.dll, libpq.dll, and ssleay32.dll) platform specific?
ie - If I have QGIS and ArcDesktop installed on the same machine, can I take a copy of those DLL files from the QGIS installation and move it to the Arc \bin\ folder and then connect to a PostgreSQL database? OR, do I need to have a specific set of the DLLs for each platform (QGIS/ArcDesktop)?
EDIT - For Clarification:
This ESRI Help Article says that in order to set up a connection between ArcGIS and a PostgreSQL database I need to download a set of DLL files from the ESRI Customer Care Portal and place them in the \bin\ folder of my current ArcGIS installation.
I noticed that I already have a set of these files that were installed with QGIS. Can I just use that copy (from QGIS) in place of the ones I would download from ESRI?
