Hi List,
What can I assume about the pgroute run time envroment ? Does it support c++???
If I want to write some c++ code for the pg route library can I assume that standard envromental std functions such as vector will exist ?
Can I write a implement code using a standard c++ template feature?
Dave.

You can link whatever your need into the library you create to be dynamically loaded. We have functions that use std::* and use Boost which is all C++ templates.
You have to start with some thing C code to handle the interface with plpgsql can create the library interface that postgresql calls but that can then call C++ functions. Look at the bi-directional code for an example.

Thanks Steve,
Some of the KSP stuff is written in C++, I was looking at some of the OR stuff.
There seems to be a rather useful function in there for doing Shortest Hamiltonian Path Problem, true is limited to 31 vertexes, but I think it would address all the problems that I am interested in.
