Before you can compile 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 when linking all the .os to make the exe.

(If you got to this page before reading full install -- refer to [UsersWikiWinCompile Compiling PostGIS under Windows (basic)]

'''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. Follow the instructions in the readme.txt -- repeated below

         a) create folder c:\opt\gtk [[BR]]
         b) extract contents of zip to the new folder [[BR]]
         c) add c:\opt\gtk\bin to your windows environment search path [[BR]]
         d) launch msys  and run following: [[BR]] 
            pkg-config --cflags gtk+-2.0 [[BR]]
         e) gtk-demo (and verify it opens a gui)


'''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. export PKG_CONFIG_PATH=/c/opt/gtk/lib/pkgconfig 
       6. ''configure --prefix=/c/postgresql --with-pgconfig=/c/postgresql/bin/pg_config --with-geosconfig=/c/postgresql/bin/geos-config --with-projdir=/c/postgresql'' --with-gui
       7. ''make clean && make''
       8. ''make install''
       9. ''make check''
