The libpqxx Portfile 52808 2009-06-23 17:48:20Z dweber macports.org $

PortSystem 1.0

Name: libpqxx
Version: 3.0.1

Category: databases devel

Maintainers: dweber openmaintainer

Description: Official C++ client API for PostgreSQL

Long Description: libpqxx is the official C++ client API for PostgreSQL, the enterprise-strength open-source database software. There are many similar libraries for PostgreSQL and for other databases, some of them database independent. Most of these, however, are fairly C like in their programming style, and fail to take advantage of the full power of the C++ language as it has matured since the acceptance of the Standard in 1996. What libpqxx brings you is effective use of templates to reduce the inconvenience of dealing with type conversions, standard C++ strings to keep you from having to worry about buffer allocation and overflow attacks, exceptions to take the tedious and error prone plumbing around error handling out of your hands, constructors and destructors to bring resource management under control, and even basic object orientation to give you some extra reliability features that would be hard to get with most other database interfaces.

If you haven't already installed Darwin Ports, you can find easy instructions for doing so at the main Darwin Ports page.
Once Darwin Ports has been installed, in a terminal window and while online, type the following and hit return:

%  cd /opt/local/bin/portslocation/dports/libpqxx
%  sudo port install libpqxx  
Password: 

You will then be prompted for your root password, which you should enter. You may have to wait for a few minutes while the software is retrieved from the network and installed for you. Y ou should see something that looks similar to:

--->  Fetching libpqxx
--->  Verifying checksum for libpqxx
--->  Extracting libpqxx
--->  Configuring libpqxx
--->  Building libpqxx with target all

--->  Staging libpqxx into destroot

--->  Installing libpqxx

- Make sure that you do not close the terminal window while Darwin Ports is working. Once the software has been installed, you can find further information about using libpqxx with these commands:

%  man libpqxx
%  apropos libpqxx
%  which libpqxx
%  locate libpqxx
