== Compiling using Mingw64-w64, Mingw64-w32  for 64-bit/32-bit (work in Progress) ==
[wiki:UsersWikiWinCompile Back to Compiling in Windows]

If you want to get to the last step fast to immediately start compiling PostGIS without having to compile the dependencies,
you can download our prepared mingw64+msys build environment which you can download from  [http://www.bostongis.com/postgisstuff/ming64.zip] and for 32-bit (for PostgreSQL 9.2+ (32-bit 9.1 and below have to use old msys chain) [http://www.bostongis.com/postgisstuff/ming32.zip]

If you want to start with your own mingw64 install and then add additional items refer to [DevWikiMingW64_Setup]
== 3.b create project folders ==

{{{
 cd ${PROJECTS}
 mkdir pgx${OS_BUILD}
 mkdir postgresql
 mkdir geos
 mkdir proj
 mkdir docbook
 ls

}}}

== GDAL ==
{{{
export GDAL_VER=1.9.2
cd ${PROJECTS}/gdal
wget http://download.osgeo.org/gdal/gdal-${GDAL_VER}.tar.gz
tar xvfz gdal-${GDAL_VER}.tar.gz
cd gdal-${GDAL_VER}
./configure --host=${MINGHOST}--build=x86_64-w64-mingw32 --with-threads=no --prefix=${PROJECTS}/gdal/rel-${GDAL_VER}w${OS_BUILD} 
make && make install
cd ${PROJECTS}/gdal/rel-${GDAL_VER}w${OS_BUILD}/bin
strip *.dll
}}}

== DOWNLOAD DOCBOOK ==

{{{
cd ${PROJECTS}/docbook
}}}

Download the latest Docbook from http://sourceforge.net/projects/docbook/files/docbook-xsl/
into that folder and untar.

Extract somewhere. In this case I chose my projects folder.  You'll need to set this folder for the --with-xsldir
setting

You should have a folder now docbook/docbook-xsl-1.76.1  or something similar


== 4. Compiling GEOS ==

Download latest GEOS source from http://trac.osgeo.org/geos/ 
You can also use the trunk svn version https://svn.osgeo.org/geos/trunk which is what we use. 
NOTE: To take advantage of new functions like [http://www.postgis.org/documentation/manual-svn/ST_DelaunayTriangles.html ST_DelaunayTriangles], you need GEOS 3.4dev which is trunk
If you are using svn version, make sure to run:

{{{
sh autogen.sh
}}}
