This is a rough guide on getting the code to compile under Linux.

Download the source

See the detailed notes here

Download Qt

The code uses version 4 of Qt whilst many Linux distributions come provided with Qt many also have the older version 3. Sadly that will not do because this code uses many of the new features that are available with version 4. Not certain which version you are using, the following command should help out

qmake --version

On my machine that gave the following information

QMake version: 2.00a
Using Qt version 4.1.2 in /usr/local/Trolltech/Qt-4.1.2/lib

So my version of Qt is alright it's 4.1.2 (just as well since I've been writing the code)
If you need to download Qt so that you have the latest version then try here

Download PostGreSQL

This is a database application and currently it uses PostGreSQL as the back end, it has been tested with version 8, I'm not certain if earlier versions will work because of the way the procedures have been written. So if you do need the latest and greatest from PostGreSQL try here or locate you favourite package manager. I also recommend ensuring that you have pgAdmin III on your system, it's an invaluable tool for looking at the database.

Compile Qt

The Qt libraries need to be compiled with support for the pgsql driver. So the following configuration switch should help:

./configure -qt-sql-psql -I/usr/local/pgsql/include -L/usr/local/pgsql/lib

The above assumes that the pgsql is located in /usr/local/ if you're unable to find where the sources for pgsql are, try the following:

slocate libpq-fe.h

Once you have configured Qt you just need to make, followed by make install. Like most compiles of large programs this takes quite a while so use this time to get out enjoy some fresh air.

Compile the source

This should be a case of using the following commands:

qmake
make

Now you need to jump ahead to the section on running the program.

This is a rough guide on getting the code to compile under Windows.

Download the source

Download Qt

The code uses version 4 of Qt you can download a binary of Qt from here

Download MinGW

The open source version of Qt uses the MinGW compiler, which is available here, or if you prefer you can download the MinGW version of DevC++, select the version with Mingw/GCC.

Download PostGreSQL

This is a database application and currently it uses PostGreSQL as the back end, it has been tested with version 8, I'm not certain if earlier versions will work because of the way the procedures have been written. So if you do need the latest and greatest from PostGreSQL try here. I also recommend ensuring that you have pgAdmin III on your system, it's an invaluable tool for looking at the database. A gudie to installing postgresql is given here.

Compile Qt plugin for pgsql

The Qt installer will provide you with a basic version of Qt, unfortunately that doesn't include the SQL plugin for pgsql. Thankfully all the Qt code is provided so it is a matter of compiling it with the pgsql source. You need to know where PostGreSQL has put the included files. Typically this is in the Program Files\PostgreSQL. Unfortunately that is not very helpful because the minGW compiler doesn't take too kindly to spaces in the file path. So here is my suggestion:
Locate the Qt directory and then the psql source code, on my system it is at:

C:\Qt\4.1.2\src\plugins\sqldrivers\psql

Now copy the include and lib directories from the PostgreSQL directory, from my system that was from C:\Program Files\PostgreSQL\8.1\lib and C:\Program Files\PostgreSQL\8.1\include. Just copy those two entire folders into the psql folder. Then run qmake as follows:

qmake -o Makefile "INCLUDEPATH+=C:\Qt\4.1.2\src\plugins\sqldrivers\psql\include" "LIBS+=C:\Qt\4.1.2\src\plugins\sqldrivers\psql\lib\ms\libpq.lib" psql.pro

Then run

make

This will then generate the psql dll which will be in the C:\Qt\4.1.2\plugins\sqldrivers\ directory.

Compile the source

This should be a case of using the following commands:

qmake
make

Now you can go to the section on running the program.

Please be patient...I'm getting there.
