Quantum GIS + GRASS Windows Native Binary Building Guide

Introduction

This document is a basic guide to a Windows Native Binary building of both GRASS and Quantum GIS. It is mainly based on the following articles:

Quantum GIS Wiki - BuildingFromSource

WinGRASS Current Status

GRASS 6.3 Install

GRASS 6.3 Requirements

Paul Kelly's winGRASS Extralibs Documentation

It tries to summarise all the previous documents in a brand new "all in one" guide, written specially for beginners.

Any library or application used in this guide is intended as the latest stable release available. Otherwise, developers notes will be added, explaining why I decided to not use the latest stable release.

In order to avoid mistakes or misunderstandings, I suggest to read each paragraph entirely before to perform any action. It's very important to follow each step and command explained exactly in the same order as they are written in the guide.

The following instruction have been succesfully tested on both Windwows XP and Windows Vista operative systems.

1. MSYS (1.0.11)

Download the MSYS installer

Install to c:\msys

At the command prompt question for post install, type n and then enter.

MSYS supplies many utilities from UNIX world in Windows; this document could help to know more about UNIX commands;

If you want to check or post some MSYS screen outputs, just right click on MSYS text area that you want to select, and selected text will be automatically copied into Windows clipboard; now it's ready to be pasted in every other document, just using the CRTL+V keyboard shortcut.

Download the MSYS coreutils package (required by some GRASS modules and scripts):

Download the MSYS coreutils package

Unpack it to a temporary folder, then copy all the content of the coreutils-5.97 folder to c:\msys (overwrite the existing files when asked)

2. MinGW (5.1.4)

Download the MinGW installer

Select "Download and Install Current Version";

Install only "g++ compiler" and "MinGW Make";

Install to c:\msys\mingw

3. Flex (2.5.4a-1)

Download the Flex prebuilt binaries package

Unpack to c:\msys\local

The latest release of Flex is (2.5.34), but it has not still ported to Windows.

4. Bison (2.1)

Download the following archives:

Bison prebuilt binaries package

Bison prebuilt dependencies package

Unpack all to c:\msys\local (overwrite the existing files when asked)

The latest release of Bison is (2.3), but it has not still ported to Windows.

5. Zlib (1.2.3)

Download the Zlib source code

Unpack to c:\msys\local\src

Open c:\msys\local\src\zlib-1.2.3\win32\Makefile.gcc

Replace line 102 with:

INCLUDE_PATH=/usr/local/include
LIBRARY_PATH=/usr/local/lib
SHARED_LIBRARY_PATH=/usr/local/bin

At lines 109-110 delete:

-@if not exist $(INCLUDE_PATH)/nul mkdir $(INCLUDE_PATH)
-@if not exist $(LIBRARY_PATH)/nul mkdir $(LIBRARY_PATH)

After line 111 add:

-$(INSTALL) $(SHAREDLIB) $(SHARED_LIBRARY_PATH)

After line 118 add:

-$(RM) $(SHARED_LIBRARY_PATH)/$(SHAREDLIB)

Open MSYS console (double click on MSYS icon on your desktop) and type:

cd /usr/local/src/zlib-1.2.3
make -f win32/Makefile.gcc
make install -f win32/Makefile.gcc

For unknown reasons, zlib1.dll information label displays that it is 1.2.2.0 version, while actually it is 1.2.3.

6. Libpng (1.2.29)

Download the Libpng source code

Unpack to c:\msys\local\src

Open c:\msys\local\src\libpng-1.2.29\scripts\makefile.mingw

After line 40 add:

prefix=/usr/local

At lines 52-53 edit:

ZLIBLIB=/usr/local/lib
ZLIBINC=/usr/local/include

In MSYS console, type:

cd /usr/local/src/libpng-1.2.29
cp scripts/makefile.mingw ./Makefile
make

Because make install procedure fails, we need to install it manually:

mkdir /usr/local/lib/pkgconfig
mkdir /usr/local/man/man3
mkdir /usr/local/man/man5
install -m 644 libpng.a /usr/local/lib
install -m 644 libpng.dll.a /usr/local/lib
install -s -m 755 libpng12.dll /usr/local/bin
install -m 644 libpng.pc /usr/local/lib/pkgconfig
install -m 644 png.h pngconf.h /usr/local/include
install -m 644 libpngpf.3 libpng.3 /usr/local/man/man3
install -m 644 png.5 /usr/local/man/man5
cp libpng-config /usr/local/bin
chmod 755 /usr/local/bin/libpng-config

An easy way to do that is to copy the previous code and and paste it in a new document; name it install-libpng.sh and save it into Libpng source code directory; then go to MSYS console and type: install-libpng.sh

7. Libjpeg (6b)

Download the Libjpeg source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/jpeg-6b
./configure --prefix=/usr/local --enable-shared
make
mkdir /usr/local/man/man1
make install

Because make procedure doesn't create the shared library (even if enabled by configure), we need to build it manually:

COMOBJECTS="jcomapi.o jutils.o jerror.o jmemmgr.o jmemnobs.o"
CLIBOBJECTS="jcapimin.o jcapistd.o jctrans.o jcparam.o \
jdatadst.o jcinit.o jcmaster.o jcmarker.o jcmainct.o \
jcprepct.o jccoefct.o jccolor.o jcsample.o jchuff.o \

LIBOBJECTS="$CLIBOBJECTS $DLIBOBJECTS $COMOBJECTS"
COBJECTS="cjpeg.o rdppm.o rdgif.o rdtarga.o rdrle.o rdbmp.o rdswitch.o cdjpeg.o"
DOBJECTS="djpeg.o wrppm.o wrgif.o wrtarga.o wrrle.o wrbmp.o rdcolmap.o cdjpeg.o"
TROBJECTS="jpegtran.o rdswitch.o cdjpeg.o transupp.o"
for i in *.exe ; do rm /usr/local/bin/$i ; done
rm *.exe
cd .libs
rm libjpeg.a
rm /usr/local/lib/libjpeg.a
cd ..
gcc -shared -s -o ./.libs/libjpeg.dll -lm -Wl,--out-implib,./.libs/libjpeg.a  $LIBOBJECTS
gcc -s -g -O2 -o cjpeg.exe $COBJECTS -L./.libs/ -ljpeg
gcc -s -g -O2 -o djpeg.exe $DOBJECTS -L./.libs/ -ljpeg
gcc -s -g -O2 -o jpegtran.exe $TROBJECTS -L./.libs/ -ljpeg
gcc -s -g -O2 -o rdjpgcom.exe rdjpgcom.o -L./.libs/ -ljpeg
gcc -s -g -O2 -o wrjpgcom.exe wrjpgcom.o -L./.libs/ -ljpeg
cd .libs
install libjpeg.a /usr/local/lib
install libjpeg.dll /usr/local/bin
cd ..
for i in *.exe ; do install $i /usr/local/bin ; done

Referring to the MinGW and GCC Documetation (Compiling and Building with MinGW and GCC Command Options - Options for Linking), I guess that the right procedure to build shared libraries (and executables that use them) with MinGW/MSYS should be as follows:

First of all we need to delete the static import library built by the standard make procedure, and then all the executables built linking against the static libraries. After that, we will build a shared library with the related import static one, and then all the needed executables, that will be linked against the new shared library.

8. Libtiff (3.8.2)

Download the Libtiff source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/tiff-3.8.2
./configure --prefix=/usr/local \
--with-zlib-lib-dir=/usr/local/lib \
--with-zlib-include-dir=/usr/local/include \
--with-jpeg-lib-dir=/usr/local/bin \
--with-jpeg-include-dir=/usr/local/include

Libtiff should be thus configured as follows:

Libtiff is now configured for i686-pc-mingw32

  Installation directory:             /usr/local
  Documentation directory:            ${prefix}/share/doc/tiff-3.8.2
  C compiler:                         gcc -g -O2 -Wall -W
  C++ compiler:                       g++ -g -O2
  Enable runtime linker paths:        no
  Support Microsoft Document Imaging: yes

 Support for internal codecs:
  CCITT Group 3 & 4 algorithms:       yes
  Macintosh PackBits algorithm:       yes
  LZW algorithm:                      yes
  ThunderScan 4-bit RLE algorithm:    yes
  NeXT 2-bit RLE algorithm:           yes
  LogLuv high dynamic range encoding: yes

 Support for external codecs:
  ZLIB support:                       yes
  Pixar log-format algorithm:         yes
  JPEG support:                       yes
  Old JPEG support:                   no

  C++ support:                        yes

  OpenGL support:                     no

Now build Libtiff:

make
make install

9. Xdr (4.0)

Download the Xdr source code (special stripped-down version with networking code removed)

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/xdr-4.0-mingw2
./configure --prefix=/usr/local --build=i686-pc-mingw32
make
make install

Must compile this only as a static library, because of obscure problems with GRASS using shared one!

10. Freetype (2.3.5)

Download the Freetype source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/freetype-2.3.5
./configure --prefix=/usr/local
make
make install

To complete the installation type:

cd /usr/local/include
mkdir freetype
mkdir ./freetype/config
cd ./freetype2/freetype/config
mv * /usr/local/include/freetype/config
cd ..
rmdir config
mv * /usr/local/include/freetype
cd ..
rmdir freetype
cd ..
rmdir freetype2

Open c:\msys\local\lib\pkgconfig\freetype2.pc

At line 11 replace:

Cflags: -I${includedir}/freetype2 -I${includedir}

with:

Cflags: -I${includedir}

11. FFTW (3.1.2)

Download the FFTW source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/fftw-3.1.2
./configure --prefix=/usr/local \
--disable-fortran \
--with-our-malloc16 \
--enable-shared \
--disable-static \
--enable-threads \
--with-combined-threads \
--enable-portable-binary \
--enable-sse2
make
make install

12. PDCurses (3.3)

Download the PDCurses source code

Unpack to c:\msys\local\src

Open c:\msys\local\src\PDCurses-3.3\win32\mingwin32.mak

At line 80 replace:

-copy pdcurses.a panel.a

with:

-cp pdcurses.a panel.a

In MSYS console, type:

cd /usr/local/src/PDCurses-3.3
cd win32
make -f mingwin32.mak DLL=Y all
cp pdcurses.a libcurses.a
install libcurses.a /usr/local/lib
install pdcurses.dll /usr/local/bin
cd ..
install -m 644 curses.h /usr/local/include

13. PROJ.4 (4.6.0)

Download the PROJ.4 source code

Unpack to c:\msys\local\src

Download the US, Canadian and New Zealand datum shift grids

Unpack to c:\msys\local\src\proj-4.6.0\nad

In MSYS console, type:

cd /usr/local/src/proj-4.6.0
./configure --prefix=/usr/local --enable-shared --disable-static
make
make install

Because make procedure doesn't create shared library (even if enabled by configure), we need to build it manually:

cd src
for i in *.exe ; do rm /usr/local/bin/$i ; done
rm /usr/local/bin/invgeod.exe
rm /usr/local/bin/invproj.exe
rm *.exe
cd .libs
rm libproj.a
rm /usr/local/lib/libproj.a
gcc -shared -s -o libproj.dll -lm -Wl,--out-implib,libproj.a *.o
cd ..
gcc -s -g -O2 -o cs2cs.exe cs2cs.o gen_cheb.o p_series.o .libs/emess.o -L./.libs/ -lproj
gcc -s -g -O2 -o geod.exe geod.o geod_set.o geod_for.o geod_inv.o .libs/emess.o -L./.libs/ -lproj
gcc -s -g -O2 -o nad2bin.exe nad2bin.o -L./.libs/ -lproj
gcc -s -g -O2 -o nad2nad.exe nad2nad.o .libs/emess.o -L./.libs/ -lproj
gcc -s -g -O2 -o proj.exe proj.o gen_cheb.o p_series.o .libs/emess.o -L./.libs/ -lproj
cp proj.exe invproj.exe
cp geod.exe invgeod.exe
cd .libs
install libproj.a /usr/local/lib
install libproj.dll /usr/local/bin
cd ..
for i in *.exe ; do install $i /usr/local/bin ; done

14. GEOS (3.0.0)

Download the GEOS source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/geos-3.0.0
./configure --prefix=/usr/local
make
make install

15. GSL (1.11)

Download the GSL source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/gsl-1.11
./configure --prefix=/usr/local
make
make install

16. Expat (2.0.1)

Download the Expat source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/expat-2.0.1
./configure --prefix=/usr/local
make
make install

17. PostgreSQL (8.3.1)

Download the PostgreSQL source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/postgresql-8.3.1
./configure --prefix=/usr/local/pgsql \
--with-includes=/usr/local/include \
--with-libraries=/usr/local/lib \
--without-readline
make
make install

Even if a prebuilt PostgreSQL Windows binary package is available, it generates problems with GDAL building. This because the Windows release of PostgreSQL is built using Visual Studio, while MinGW (and specially GDAL built with MinGW) has problems linking against VS built libraries.

18. SQLite (3.5.9)

Download the SQLite source code

Unpack to c:\msys\local\src

In MSYS console, type:

cd /usr/local/src/sqlite-amalgamation-3.5.9
./configure --prefix=/usr/local/sqlite
make
make install

19. GDAL (1.5.2) - Step One

Since Quantum GIS needs GDAL with GRASS support, we will do as follows:

Build and install GDAL without GRASS support
Build and install GRASS
Rebuild and install GDAL with GRASS support

According to the previous items, now we will build and install GDAL without GRASS support:

Download the GDAL source code

Unpack to c:\msys\local\src

Open c:\msys\local\src\gdal-1.5.2\configure

At line 23832 replace:

expat_lib_flags="-L$expat_prefix/lib -lexpat"

with:

LIBS="$LIBS -L$expat_prefix/lib -lexpat"

In MSYS console, type:

cd /usr/local/src/gdal-1.5.2
./configure --prefix=/usr/local \
--without-grass \
--with-sqlite3=/usr/local/sqlite \
--with-pg=/usr/local/pgsql/bin/pg_config.exe

When finished, you should have the following screen output:

GDAL is now configured for i686-pc-mingw32

  Installation directory:    	/usr/local
  C compiler:                	gcc -g -O2
  C++ compiler:              	g++ -g -O2

  LIBTOOL support:           	yes

  LIBZ support:              	internal

  LIBGEOTIFF support:        	internal
  LIBJPEG support:           	internal
  LIBGIF support:            	internal
  OGDI support:              	no
  HDF4 support:              	no
  HDF5 support:              	no
  Kakadu support:            	no
  JasPer support:            	no
  ECW support:               	no
  MrSID support:             	no
  GRIB support:              	no
  cURL support (wms/wcs/...):	no
  PostgreSQL support:        	yes
  MySQL support:             	no
  Xerces-C support:          	no
  Expat support:             	yes
  ODBC support:              	no
  PGeo support:              	no
  OCI support:               	no
  SDE support:               	no
  DODS support:              	no
  SQLite support:            	yes
  DWGdirect support          	no
  PANORAMA GIS support:      	no
  INFORMIX DataBlade support:	no
  GEOS support:              	yes


  Old-gen python          	no
  SWIG Bindings:          	no

  Statically link PROJ.4:    	no
  enable OGR building:       	yes
  enable pthread support:    	no
  hide internal symbols:     	no

Open c:\msys\local\src\gdal-1.5.2\GNUmakefile

After line 4 add:

GDAL_ROOT=.

Finally build and install GDAL:

make
make install

Enabling external support for Zlib, Libpng, Libjpeg and Libtiff makes GDAL's build procedure to fail;

The distributed Windows binary package of Python is built using Visual Studio, while GDAL (if built with MinGW) requires a MinGW built version of Python; this means that, if you want to enable Python bindings in GDAL, you'll need to build Python from source using MinGW;

The same problem applies to the OGDI support.

Download the GRASS source code

Unpack to c:\msys\local\src

Open c:\msys\local\src\grass-6.3.0\man\Makefile

At line 13, replace:

Having GRASS successfully configured, now you can build it:

export PATH="/usr/local/bin:/usr/local/tcl-tk/bin:/usr/local/sqlite/bin:/usr/local/pgsql/lib:$PATH"
make

When finished, you should have the following compilation log:

In case of errors please change into the directory with error and run 'make'.
If you get multiple errors, you need to deal with them in the order they
appear in the error log. If you get an error building a library, you will
also get errors from anything which uses the library.

make: *** [default] Error 1

The best way to check it, is to open c:\msys\local\src\grass-6.3.0\error.log using your favourite web client.

Then install GRASS:

make install

Now GRASS should be installed in c:\msys\local\grass-6.3.0

25. GDAL (1.5.2) - Step Two

26. Qt OpenSource (4.4.0)

Download the Qt OpenSource installer

Install to C:\DevTools\Qt-OpenSource

When the installer will ask for MinGW, you don't need to download and install it, just point the installer to c:\msys\mingw

At the alert message "The installer could not found a valid c:\msys\mingw\include\w32api.h", press "Yes" and continue.

When Qt installation is complete, edit C:\DevTools\Qt-OpenSource\bin\qtvars.bat and do as follows:

At line 8 replace:

echo -- PATH set to C:\DevTools\Qt-OpenSource\bin

with:

echo -- Adding MSYS environment directories to PATH

At line 14 replace:

set PATH=C:\DevTools\Qt-OpenSource\bin

with:

set PATH=%PATH%;c:\msys\local\bin;c:\msys\local\sqlite\bin;c:\msys\local\pgsql\lib

Finally, add C:\DevTools\Qt-OpenSource\bin to your PATH system variable.

27. Python (2.5.2)

Download the Python installer

Install to C:\DevTools\Python

Add C:\DevTools\Python to your PATH system variable.

28. SIP (4.7.6)

Download SIP source code

Unpack to c:\msys\local\src

Open a Windows terminal and type:

cd c:\msys\local\src\sip-4.7.6

In CMake Setup utility press "Configure" button and, when asked, choose "MinGW Makefiles" as generator.

CMake Setup will alert you for missing dependencies; don't care, press OK and continue.

When finished, select "Show Advanced Values" checkbox.

For each item listed below, select the related box in the CMake Setup utility, type in the suggested value and then press enter (we will perform a "bottom-up" procedure, editing last values of the CMake Setup list as first):

SQLITE3_LIBRARY = c:/msys/local/sqlite/bin/libsqlite3-0.dll
SQLITE3_INCLUDE_DIR = c:/msys/local/sqlite/include
POSTGRES_INCLUDE_DIR = c:/msys/local/pgsql/include
GRASS_PREFIX = c:/msys/local/grass-6.3.0
CMAKE_INSTALL_PREFIX = c:/msys/local/qgis-0.11.0
CMAKE_CXX_FLAGS = -DGEOS_INLINE
