I can confirm that the PROJ_LIB environment variable is not set in the httpd configuration file. Adding it has solved the problem. Yay!!
In addition, I got some answers to my questions regarding where MapServer was getting this information if that environment variable wasn't in the Apache configuration. By default, it was using a directory provided at compile time, as suggested in a previous post. Obviously, that path wasn't the same as the one we thought it was using. Now we know and our choice is either to leave the PROJ_LIB environment variable set or to just overwrite the epsg file in the proper location. Special thanks to Jeff for his input here. -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/msProcessProjection-Projection-library-error-no-options-in-init-file-tp6273726p6277431.html Sent from the Mapserver - User mailing list archive at Nabble.com. _______________________________________________ mapserver-users mailing list mapserver-users@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/mapserver-users
