====================================

==========

MSYS provides a unix style build environment under windows. We have created a

document.

==========

Download qt4.3 opensource precompiled edition exe and install (including the

===================

*** Note I think this section can be removed as it should be installed int the

(the zip bin) and extract it into c:\msys\mingw\bin

=============================

Follow this section in case you would like to use Python bindings for QGIS. To

be able to compile bindings, you need to compile SIP and PyQt4 from sources as

their installer doesn't include some development files which are necessary.

==========================================================

(It doesn't matter to what folder you'll install it)

http://python.org/download/

=====================================

http://www.riverbankcomputing.com/Downloads/sip4/

to get versions that match your current Qt installed version.

==================

===================

=========================

/!\ You can delete the directories with unpacked SIP and PyQt4 sources after a

successfull install, they're not needed anymore.

================

In order to check out QGIS sources from the repository, you need Subversion

http://subversion.tigris.org/files/documents/15/36797/svn-1.4.3-setup.exe

===========

CMake is build system used by Quantum GIS. Download it from here:

http://www.cmake.org/files/v2.4/cmake-2.4.6-win32-x86.exe

==========

Start a cmd.exe window ( Start -> Run -> cmd.exe ) Create development

===============

As a background read the generic building with CMake notes at the end of

==================

When configuration is done, click 'OK' to exit the setup utility.

==================================

make make install

=================================================================================

Make sure to copy all .dll:s needed to the same directory as the qgis.exe

used from that place.

=================================================

Downlad and install NSIS from (http://nsis.sourceforge.net/Main_Page)

on qgis.nsi and choose the option 'Compile NSIS Script'.

==============================================================

In this approach I will try to avoid as much as possible building dependencies

from source and rather use frameworks wherever possible.

==================

I recommend to get the latest xcode dmg from the Apple XDC Web site. Install

XCODE after the ~941mb download is complete.

==========================

You need a minimum of Qt4.2. I suggest getting the latest (at time of writing).

=========================================================

Download William Kyngesburye's excellent all in one framework that includes

provided as frameworks so we will need to build these from source.

====================================

Retrieve the Gnu Scientific Library from

======================================

Get the expat sources:

====================================

Retrieve the python bindings toolkit SIP from

=====================================

Make sure you have the latest python fom

======================================

The version of bison available by default on Mac OSX is too old so you need to

==========================

Get the latest release from here:

Once downloaded open the dmg and run the installer

===============================

The http://sourceforge.net/projects/macsvn/ (MacSVN) project has a downloadable

Now close and reopen your shell to get the updated vars.

============================

Now we are going to check out the sources for QGIS. First we will create a

I suggest you press 'p' to accept the key permanently.

========================

CMake supports out of source build so we will create a 'build' dir for the

================

I had some issues with GEOS headers so I made the following edits:

In file /Library/Frameworks/GEOS.framework/Headers/geom.h, comment out line 145

=============

Now we can start the build process:

========================

=============================

*Requires:* Ubuntu Edgy / Debian derived distro

to you.

================

The packages qgis depends on to build are available in the "universe" component

================

above commands to select the Qt4 version of the relevant applications.

==============================================================

sudo apt-get install gdal-bin libgdal1-dev libgeos-dev proj \

libgdal-doc libhdf4g-dev libhdf4g-run python-dev \

libsqlite3-dev sqlite3 ccache make libpq-dev flex bison cmake txt2tags \

python-qt4 python-qt4-dev python-sip4 sip4 python-sip4-dev

language bindings you may need to build and install those packages from source.

=========================

/!\ *Note:* If you don't need to build with GRASS support, you can

/!\ You may need to explicitly state your grass version e.g. libgdal1-1.3.2-grass

============================

You should also setup ccache to speed up compile times:

=========================================

As a convention I do all my development work in $HOME/dev/<language>, so in

This directory path will be assumed for all instructions that follow.

===================================

There are two ways the source can be checked out. Use the anonymous method

=========================

I compile my development version of QGIS into my ~/apps directory to avoid

It may take a little while to build depending on your platform.

==================

Now you can try to run QGIS:

on your screen.

==============================================================

==================

===========

This is the environment that supplies many utilities from UNIX world in Windows and is needed

All stuff we're going to compile is going to get to this directory (resp. its subdirs).

============

Download from here:

It suffices to download and install only g++ and mingw-make components.

=====================

Flex and Bison are tools for generation of parsers, they're needed for GRASS and also QGIS compilation.

Unpack them all to c:\msys\local

============================

====================

Paul Kelly did a great job and prepared a package of precompiled libraries for GRASS.

Unpack the whole package to c:\msys\local

=====================

Since Quantum GIS needs GDAL with GRASS support, we need to compile GDAL

Make and make install should be hassle free after this.

============

Grab sources from CVS or use a weekly snapshot, see:

- http://geni.ath.cx/grass.html

=====================

At this stage, we'll use GDAL sources we've used before, only the compilation will be a bit different.

Now, GDAL should be able to work also with GRASS raster layers.

===========

Download the sources:

=============

You can use precompiled DLL, no need to compile from source:

and copy sqlite3.h to c:\msys\local\include

==========

Download sources:

============

Download sources:

===============

We're going to use precompiled binaries. Use the link below for download:

copy contents of pgsql directory from the archive to c:\msys\local

============

We're done with preparation of MSYS environment. Now you can delete all stuff in c:\msys\local\src - it takes quite a lot

of space and it's not necessary at all.

=================================

Note that this does not currently include GRASS or Python plugins.

========================

This section describes the setup required to allow Visual Studio to be used to build QGIS.

======================

The free Express Edition lacks the platform SDK which contains headers and so on that are needed when building QGIS. The platform SDK can be installed as described here:

http://www.codeproject.com/wtl/WTLExpress.asp

===================

You will need stdint.h and unistd.h. unistd.h comes with GnuWin32 version of flex & bison binaries (see later). stdint.h can be found here:

Copy both of these to <vsinstalldir>\VC\include.

==================================

This section describes the downloading and installation of the various QGIS dependencies.

=====================

Flex and Bison are tools for generation of parsers, they're needed for GRASS and also QGIS compilation.

http://gnuwin32.sourceforge.net/downlinks/bison.php

=========

Build Qt following the instructions here:

http://wiki.qgis.org/qgiswiki/Building_QT_4_with_Visual_C%2B%2B_2005

=============

Get proj.4 source from here:

This can also be added to a batch file.

==========

Get gsl source from here:

Build using the gsl.sln file

===========

Get geos from svn (svn checkout http://svn.refractions.net/geos/trunk geos).

This can also be added to a batch file.

===========

Get gdal from svn (svn checkout https://svn.osgeo.org/gdal/branches/1.4/gdal gdal).

==============

Get PostGIS and the Windows version of PostgreSQL from here:

Note the warning about not installing the version of PostGIS that comes with the PostgreSQL installer. Simply run the installers.

============

Get expat from here:

Simply run the executable to install expat.

============

Get CMake from here:

You'll need cmake-<version>-win32-x86.exe. Simply run this to install CMake.

=============================

Get QGIS source from svn (svn co https://svn.qgis.org/repos/qgis/trunk/qgis qgis).
