I'm not a linking guru... Is there a penalty for setting LDFLAGS+= -lstdc++ when building postgresql?
Postgis includes a bunch of useful functions for manipulating spatial data. Some of them are provided by geos, a separate c++ library, with postgis providing wrappers.
According to postgis docs, postgresql _must_ be configured with LDFLAGS containing -lstdc++ for this to work. I can confirm this.
The postgis port provides the WITH_GEOS tunable, but it has no effect unless the above adjustment is made to postgresql. The port makes no mention of this. Is there a penalty in just leaving LDFLAGS+= -lstdc++ in the postgresql port Makefile? Bad idea? What do you think?
I'd rather use a libgeos wrapper using just extern "C" entry points, not the C++ mangled entries.
Haven't checked yet how much trouble this may cause on geos, and if it will work with the exceptions. And if a simple .def with aliases would be enough. libgeos is huge.
