Before you can install PostGIS 1.4 with the slick graphical interface for shp2pgsql, you need to install GTK++ 2.8 or above. This is still a work in progress -- since I got as far as getting it to compile to .o but failed at the linker. 1. Install GTK++ Bundle

1. Download GTK++ bundle described on this page ​http://www.gtk.org/download-windows.html.

The direct link is

(​http://ftp.gnome.org/pub/gnome/binaries/win32/gtk+/2.16/gtk+-bundle_2.16.2-20090601_win32.zip)

2. Compiling PostGIS SVN 1.4 (with shp2pgql-gui)

1. Download postgis.refractions.net/download/postgis-1.4.0SVN.tar.gz and put in C:/thesrc
2. cd /c/thesrc
3. gzip -d -c postgis-1.4.0SVN.tar.gz | tar xvf -
4. cd postgis-svn
5. configure --prefix=/c/postgresql --with-pgconfig=/c/postgresql/bin/pg_config --with-geosconfig=/c/postgresql/bin/geos-config --with-projdir=/c/postgresql
6. make clean && make
7. make install
8. make check
