[fdo-users] PostGIS provider undefined symbols

[Greg1975]

Yes, they do exist in the same directory as the Postgis provider. There's no
reference in libPostGISProvider.so to libExpressionEngine-3.4.0.so, so I
guess libtool failed but at the moment
I know next to nothing about libtool to fix it myself, if someone
knowledgeable took a look at the build scripts the problem probably would be
solved straight away by a simple tweak.
I'm looking forward to your reply. Thanks.

Greg
