= Creation of MSYS environment for compilation of Quantum GIS
(including all dark magic involved) =

== Initial setup ==

=== MSYS ===

This is the environment that supplies many utilities from UNIX world in Windows and is needed
by many dependencies to be able to compile.

Download from here:
http://puzzle.dl.sourceforge.net/sourceforge/mingw/MSYS-1.0.11-2004.04.30-1.exe

Install to ``c:\msys``

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

=== MinGW ===

Download from here:
http://puzzle.dl.sourceforge.net/sourceforge/mingw/MinGW-5.1.3.exe

Install to ``c:\msys\mingw``

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

=== Flex and Bison ===

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

Download the following packages:
http://gnuwin32.sourceforge.net/downlinks/flex-bin-zip.php

http://gnuwin32.sourceforge.net/downlinks/bison-bin-zip.php

http://gnuwin32.sourceforge.net/downlinks/bison-dep-zip.php

Unpack them all to ``c:\msys\local``


== Installing dependencies ==

=== Getting ready ===

Paul Kelly did a great job and prepared a package of precompiled libraries for GRASS.
The package currently includes:

- zlib-1.2.3
- libpng-1.2.16-noconfig
- xdr-4.0-mingw2
- freetype-2.3.4
- fftw-2.1.5
- PDCurses-3.1
- proj-4.5.0
- gdal-1.4.1


It's available for download here:
http://www.stjohnspoint.co.uk/grass/wingrass-extralibs.tar.gz

Moreover he also left the notes how to compile it (for those interested):
http://www.stjohnspoint.co.uk/grass/README.extralibs

Unpack the whole package to ``c:\msys\local``


=== GDAL level one ===

Since Quantum GIS needs GDAL with GRASS support, we need to compile GDAL
from source - Paul Kelly's package doesn't include GRASS support in GDAL.
The idea is following:
+ compile GDAL without GRASS
+ compile GRASS
+ compile GDAL with GRASS


So, start with downloading GDAL sources:
http://download.osgeo.org/gdal/gdal141.zip

Unpack it to some directory, preferably ``c:\msys\local\src``.

Start MSYS console, go to gdal-1.4.1 directory and run the commands below.
You can put them all to a script, e.g. build-gdal.sh and run them at once.
The recipe is taken from Paul Kelly's instructions - basically they
just make sure that the library will be created as DLL and the utility
programs will be dynamically linked to it...

```
CFLAGS="-O2 -s" CXXFLAGS="-O2 -s" LDFLAGS=-s ./configure --without-libtool --prefix=/usr/local --enable-shared --disable-static --with-libz=/usr/local --with-png=/usr/local
make
make install
rm /usr/local/lib/libgdal.a

cd ogr

g++ -s ogr2ogr.o -o ogr2ogr.exe -lgdal -L/usr/local/lib -lpng -lz -lgdal
g++ -s ogrtindex.o -o ogrtindex.exe -lgdal -L/usr/local/lib -lpng -lz -lgdal
install ogrinfo.exe ogr2ogr.exe ogrtindex.exe /usr/local/bin
cd ../apps
g++ -s gdalinfo.o -o gdalinfo.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdal_translate.o -o gdal_translate.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdaladdo.o -o gdaladdo.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdalwarp.o -o gdalwarp.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdal_contour.o -o gdal_contour.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdaltindex.o -o gdaltindex.exe -L/usr/local/lib -lpng -lz -lgdal
g++ -s gdal_rasterize.o -o gdal_rasterize.exe -L/usr/local/lib -lpng -lz -lgdal
install gdalinfo.exe gdal_translate.exe gdaladdo.exe gdalwarp.exe gdal_contour.exe gdaltindex.exe gdal_rasterize.exe /usr/local/bin
```

Finally, manually edit ``gdal-config`` in ``c:\msys\local\bin`` to replace the static library reference with -lgdal:
```
CONFIG_LIBS="-L/usr/local/lib -lpng -lz -lgdal"
```

=== GRASS ===

Grab sources from CVS or use a weekly snapshot, see:
http://grass.itc.it/devel/cvs.php

In MSYS console go to the directory where you've unpacked or checked out sources
(e.g. ``c:\msys\local\src\grass-6.3.cvs``)

Run these commands:
```
export PATH="/usr/local/bin:/usr/local/lib:$PATH"
./configure --prefix=/usr/local --bindir=/usr/local --with-includes=/usr/local/include --with-libs=/usr/local/lib --with-cxx --without-jpeg --without-tiff --without-postgres --with-opengl=windows --with-fftw --with-freetype --with-freetype-includes=/usr/local/include/freetype2 --without-x --without-tcltk --enable-x11=no --enable-shared=yes --with-proj-share=/usr/local/share/proj
make
make install
```

It should get installed to ``c:\msys\local\grass-6.3.cvs``

By the way, these pages might be useful:

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


=== GDAL level two ===

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

But first in order to be able to compile GDAL sources with current GRASS CVS, you need to patch them, here's what you need to change:
http://trac.osgeo.org/gdal/attachment/ticket/1587/plugin_patch_grass63.diff
(you can patch it by hand or use patch.exe in ``c:\msys\bin``)

Now in MSYS console go to the GDAL sources directory and run the same commands as in level one, only with these differences:

+ when running ``./configure`` add this argument: ``--with-grass=/usr/local/grass-6.3.cvs``
+ when calling ``g++`` on line 5 (which creates libgdal.dll), add these arguments: ``-L/usr/local/grass-6.3.cvs/lib -lgrass_vect -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase -lgrass_I -lgrass_gproj -lgrass_vask -lgrass_gmath -lgrass_gis -lgrass_datetime``


Then again, edit ``gdal-config`` and change line with CONFIG_LIBS
```
CONFIG_LIBS="-L/usr/local/lib -lpng -L/usr/local/grass-6.3.cvs/lib -lgrass_vect -lgrass_dig2 -lgrass_dgl -lgrass_rtree -lgrass_linkm -lgrass_dbmiclient -lgrass_dbmibase -lgrass_I -lgrass_gproj -lgrass_vask -lgrass_gmath -lgrass_gis -lgrass_datetime -lz -L/usr/local/lib -lgdal"
```

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

=== GEOS ===

Download the sources:
http://geos.refractions.net/geos-2.2.3.tar.bz2

Unpack to e.g. ``c:\msys\local\src``

To compile, I had to patch the sources: in file ``source/headers/timeval.h`` line 13.
Change it from:
```
#ifdef _WIN32
```
to:
```
#if defined(_WIN32) && defined(_MSC_VER)
```

Now, in MSYS console, go to the source directory and run:

```
./configure --prefix=/usr/local
make
make install
```


=== SQLITE ===

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

Download this archive:
http://www.sqlite.org/sqlitedll-3_3_17.zip

and copy sqlite3.dll from it to ``c:\msys\local\lib``

Then download this archive:
http://www.sqlite.org/sqlite-source-3_3_17.zip

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


=== GSL ===

Download sources:
ftp://ftp.gnu.org/gnu/gsl/gsl-1.9.tar.gz

Unpack to ``c:\msys\local\src``

Run from MSYS console in the source directory:

```
./configure
make
make install
```

=== EXPAT ===

Download sources:
http://dfn.dl.sourceforge.net/sourceforge/expat/expat-2.0.0.tar.gz

Unpack to ``c:\msys\local\src``

Run from MSYS console in the source directory:

```
./configure
make
make install
```

=== POSTGRES ===

We're going to use precompiled binaries. Use the link below for download:
http://wwwmaster.postgresql.org/download/mirrors-ftp?file=%2Fbinary%2Fv8.2.4%2Fwin32%2Fpostgresql-8.2.4-1-binaries-no-installer.zip

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


== Cleanup ==

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.
