Compiling this package requires PostgreSQL to be installed--including the C headers for client development. The library builds on top of PostgreSQL's standard C API, libpq. The libpq headers are not needed to compile client programs, however.
For a quick introduction to installing and using libpqxx, see the README file; a more extensive tutorial is available in doc/html/Tutorial/index.html.
The latest information, as well as updates, a mailing list, and a bug reporting system can be found at the project's home page.
