always welcome for indicating possible mistakes.
Because the code of QGIS evolves from release to release, These instructions are
regularly updated to match the corresponding release. Instructions for the current
master branch are available at
http://htmlpreview.github.io/?https://raw.github.com/qgis/QGIS/master/doc/INSTALL.html.
If you wish to build another version of QGIS, ensure to checkout the appropriate
release branch. The QGIS source code can be found in the repository (https:/qgis/QGIS).
Please visit http://qgis.org for information on joining our mailing lists
and getting involved in the project further.
/!\ Note to document writers: Please use this document as the central
place for describing build procedures. Please do not remove this notice.
/!\ Note to document writers: This document is generated from
doc/INSTALL.t2t - if you need to edit this document, be sure to edit that
file rather than the generated INSTALL document found in the root of the
source directory.
2. Overview
===========
QGIS, like a number of major projects (e.g., KDE 4.0), uses CMake
(http://www.cmake.org) for building from source.
Following a summary of the required dependencies for building:
Required build tools:
- CMake >= 3.0.0
- Flex >= 2.5.6
- Bison >= 2.4
Required build dependencies:
- Qt >= 5.9.0
- Proj >= 4.4.x
- GEOS >= 3.4
- Sqlite3 >= 3.0.0
- SpatiaLite >= 4.2.0
- libspatialindex
- GDAL/OGR >= 2.1
- Qwt >= 5.0 & (< 6.1 with internal QwtPolar)
- expat >= 1.95
- QScintilla2
- QCA
- qtkeychain (>= 0.5)
- libzip
Optional dependencies:
- for GRASS providers and plugin - GRASS >= 7.0.0.
- for georeferencer - GSL >= 1.8
- for PostGIS support - PostgreSQL >= 8.0.x
- for gps plugin - gpsbabel
- for mapserver export and PyQGIS - Python >= 3.3
- for python support - SIP >= 4.12, PyQt >= 5.3 must match Qt version, Qscintilla2
- for qgis mapserver - FastCGI
- for oracle provider - Oracle OCI library
Indirect dependencies:
Some proprietary formats (e.g., ECW and MrSid) supported by GDAL require
proprietary third party libraries. QGIS doesn't need any of those itself to
build, but will only support those formats if GDAL is built accordingly. Refer
to http://gdal.org/formats_list.html ff. for instructions how to include
those formats in GDAL.
3. Building on GNU/Linux
========================
3.1. Building QGIS with Qt 5.x
==============================
Requires: Ubuntu / Debian derived distro
/!\ Note: Refer to the section Building Debian packages for building
debian packages. Unless you plan to develop on QGIS, that is probably the
easiest option to compile and install QGIS.
These notes are for Ubuntu - other versions and Debian derived distros may
require slight variations in package names.
These notes are for if you want to build QGIS from source. One of the major
aims here is to show how this can be done using binary packages for *all*
dependencies - building only the core QGIS stuff from source. I prefer this
approach because it means we can leave the business of managing system packages
to apt and only concern ourselves with coding QGIS!
This document assumes you have made a fresh install and have a 'clean' system.
These instructions should work fine if this is a system that has already been
in use for a while, you may need to just skip those steps which are irrelevant
to you.
3.2. Prepare apt
================
The packages QGIS depends on to build are available in the "universe" component
of Ubuntu. This is not activated by default, so you need to activate it:
1. Edit your /etc/apt/sources.list file.
2. Uncomment all the lines starting with "deb"
Also you will need to be running Ubuntu 'precise' or higher in order for
all dependencies to be met.
Now update your local sources database:
sudo apt-get update
3.3. Install build dependencies

(extracted from the control.in file in debian/)
See http://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu for
currently supported distributions (plain xenial's GDAL for instance is to old
and we build with GDAL2 from ubuntugis).
3.4. Setup ccache (Optional, but recommended)
=============================================
You should also setup ccache to speed up compile times:
cd /usr/local/bin
sudo ln -s /usr/bin/ccache gcc
sudo ln -s /usr/bin/ccache g++
or simply add /usr/lib/ccache to your PATH.
3.5. Prepare your development environment
=========================================
As a convention I do all my development work in $HOME/dev/<language>, so in
this case we will create a work environment for C++ development work like
this:
mkdir -p ${HOME}/dev/cpp
cd ${HOME}/dev/cpp
This directory path will be assumed for all instructions that follow.
3.6. Check out the QGIS Source Code
===================================
There are two ways the source can be checked out. Use the anonymous method
if you do not have edit privileges for the QGIS source repository, or use
the developer checkout if you have permissions to commit source code
changes.
1. Anonymous Checkout
cd ${HOME}/dev/cpp
git clone git:/qgis/QGIS.git
2. Developer Checkout
cd ${HOME}/dev/cpp
git clone [email protected]:qgis/QGIS.git
3.7. Starting the compile
=========================
I compile my development version of QGIS into my ~/apps directory to avoid
conflicts with Ubuntu packages that may be under /usr. This way for example
you can use the binary packages of QGIS on your system along side with your
development version. I suggest you do something similar:
mkdir -p ${HOME}/apps
Now we create a build directory and run ccmake:
cd QGIS
mkdir build-master
cd build-master
ccmake ..
When you run ccmake (note the .. is required!), a menu will appear where
you can configure various aspects of the build. If you want QGIS to have
debugging capabilities then set CMAKE_BUILD_TYPE to Debug. If you do not have
root access or do not want to overwrite existing QGIS installs (by your
packagemanager for example), set the CMAKE_INSTALL_PREFIX to somewhere you
have write access to (I usually use ${HOME}/apps). Now press
'c' to configure, 'e' to dismiss any error messages that may appear.
and 'g' to generate the make files. Note that sometimes 'c' needs to
be pressed several times before the 'g' option becomes available.
After the 'g' generation is complete, press 'q' to exit the ccmake
interactive dialog.
/!\ Warning: Make sure that your build directory is completely empty when you
enter the command. Do never try to "re-use" an existing Qt4 build directory.
If you want to use `ccmake` or other interactive tools, run the command in
the empty build directory once before starting to use the interactive tools.
Now on with the build:
make -jX
where X is the number of available cores. Depending on your platform,
this can speed up the build time considerably.
Then you can directly run from the build directory:
./output/bin/qgis
Another option is to install to your system:
make install
After that you can try to run QGIS:
$HOME/apps/bin/qgis
If all has worked properly the QGIS application should start up and appear
on your screen. If you get the error message "error while loading shared libraries",
execute this command in your shell.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${HOME}/apps/lib/
Optionally, if you already know what aspects you want in your custom build
then you can skip the interactive ccmake .. part by using the cmake -D
option for each aspect, e.g.:
cmake -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=${HOME}/apps ..
Also, if you want to speed your build times, you can easily do it with ninja,
an alternative to make with similar build options.
For example, to configure your build you can do either one of:
ccmake -G Ninja ..
cmake -G Ninja -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=${HOME}/apps ..
Build and install with ninja:
ninja (uses all cores by default; also supports the above described -jX option)
ninja install
You can build just the targets you need using, for example:
ninja qgis
ninja pycore
3.8. Building Debian packages
=============================
Instead of creating a personal installation as in the previous step you can
also create debian package. This is done from the QGIS root directory, where
you'll find a debian directory.
First you need to install the debian packaging tools once:
apt-get install build-essential
First you need to create an changelog entry for your distribution. For example
for Ubuntu Precise:
dch -l ~precise --force-distribution --distribution precise "precise build"
The QGIS packages will be created with:
dpkg-buildpackage -us -uc -b
/!\ Note: Install devscripts to get dch.
/!\ Note: If dpkg-buildpackage complains about unmet build dependencies
you can install them using apt-get and re-run the command.
/!\ Note: If you have libqgis1-dev installed, you need to remove it first
using dpkg -r libqgis1-dev. Otherwise dpkg-buildpackage will complain about a
build conflict.
/!\ Note: By default tests are run in the process of building and their
results are uploaded to http://dash.orfeo-toolbox.org/index.php?project=QGIS.
You can turn the tests off using DEB_BUILD_OPTIONS=nocheck in front of the
build command. The upload of results can be avoided with DEB_TEST_TARGET=test.
The packages are created in the parent directory (ie. one level up).
Install them using dpkg. E.g.:
sudo debi
3.9. On Fedora Linux
====================
We assume that you have the source code of QGIS ready and created a
new subdirectory called `build` or `build-qt5` in it.
3.9.1. Install build dependencies
=================================
dnf install qt5-qtwebkit-devel qt5-qtlocation-devel qt5-qttools-static qca-qt5-devel qca-qt5-ossl qt5-qt3d-devel python3-qt5-devel python3-qscintilla-qt5-devel qscintilla-qt5-devel python3-qscintilla-devel python3-qscintilla-qt5 clang flex bison geos-devel gdal-devel sqlite-devel libspatialite-devel qt5-qtsvg-devel qt5-qtxmlpatterns-devel spatialindex-devel expat-devel proj-devel qwt-qt5-devel gsl-devel postgresql-devel cmake python3-future gdal-python3 python3-psycopg2 python3-PyYAML python3-pygments python3-jinja2 python3-OWSLib qca-qt5-ossl qwt-qt5-devel qtkeychain-qt5-devel qwt-devel sip-devel libzip-devel exiv2-devel
To build QGIS server additional dependencies are required:
dnf install fcgi-devel
Make sure that your build directory is completely empty when you enter the
following command. Do never try to "re-use" an existing Qt4 build directory.
If you want to use `ccmake` or other interactive tools, run the following
command in the empty build directory once before starting to use the interactive
tools.
cmake ..
If everything went OK you can finally start to compile. (As usual append a -jX
where X is the number of available cores option to make to speed up your build
process)
make
Run from the build directory
./output/bin/qgis
Or install to your system
make install
3.9.2. Suggested system tweaks
==============================
By default Fedora disables debugging calls from Qt applications. This prevents
the useful debug output which is normally printed when running the unit tests.
To enable debug prints for the current user, execute:
cat > ~/.config/QtProject/qtlogging.ini << EOL
[Rules]
default.debug=true
EOL
4. Building on Windows
======================
4.1. Building with Microsoft Visual Studio
==========================================
This section describes how to build QGIS using Visual Studio (MSVC) 2015 on Windows.
This is currently also how the binary QGIS packages are made (earlier versions used MinGW).
This section describes the setup required to allow Visual Studio to be used to
build QGIS.
4.1.1. Visual C++ Community Edition
===================================
The free (as in free beer) Community installer is available under:
http://download.microsoft.com/download/D/2/3/D23F4D0F-BA2D-4600-8725-6CCECEA05196/vs_community_ENU.exe
4.1.2. Other tools and dependencies
===================================
Download and install following packages:
|| Tool | Website |
| CMake | https://cmake.org/files/v3.12/cmake-3.12.3-win64-x64.msi |
| GNU flex, GNU bison and GIT | http://cygwin.com/setup-x86.exe (32bit) or http://cygwin.com/setup-x86_64.exe (64bit) |
| OSGeo4W | http://download.osgeo.org/osgeo4w/osgeo4w-setup-x86.exe (32bit) or http://download.osgeo.org/osgeo4w/osgeo4w-setup-x86_64.exe (64bit) |
| ninja | https:/ninja-build/ninja/releases/download/v1.7.2/ninja-win.zip |
For the QGIS build you need to install following packages from cygwin:
- bison
- flex
- git
and from OSGeo4W (select Advanced Installation):
- qgis-dev-deps
This will also select packages the above packages depend on.
If you install other packages, this might cause issues. Particularly, make sure
not to install the msinttypes package. It installs a stdint.h file in
OSGeo4W[64]\include, that conflicts with Visual Studio own stdint.h, which for
example breaks the build of the virtual layer provider.
Earlier versions of this document also covered how to build all above
dependencies. If you're interested in that, check the history of this page in the Wiki
or the SVN repository.
ninja:
copy ninja.exe to d:\OSGeo4W64\bin\
4.1.3. Setting up the Visual Studio project with CMake
======================================================
/!\ Consider this section as example. It tends to outdate, when OSGeo4W and
SDKs move on. ms-windows/osgeo4w/package-nightly.cmd is used for the
nightly builds and constantly updated and hence might contain necessary
updates that are not yet reflected here.
To start a command prompt with an environment that both has the VC++ and the OSGeo4W
variables create the following batch file (assuming the above packages were
installed in the default locations):
@echo off
call X:\src\qgis\ms-windows\osgeo4w\msvc-env.bat x86_64
@cmd
Save the batch file as d:\OSGeo4W64\OSGeo4W-dev.bat and run it.
On the command prompt checkout the QGIS source from
git to the source directory QGIS:
git clone git:/qgis/QGIS.git
And, to avoid Git in Windows reporting changes to files not actually modified:
git config core.filemode false
Using configonly.bat to create the MSVC solution file:
We will be using the file ms-windows/osgeo4w/configonly.bat to create an MSVC solution file.
There are a few options for a solution file, following are the options: ninja, native MSVC.
The advantage of using native MSVC solution is that you can find the root of build problems much easily.
configonly.bat is meant to create a configured build directory with a MSVC solution file:
```
configonly.bat
```
Compiling QGIS with MSVC:
We will need to run MSVC with all the environment variables set, thus we will run it as follows:
Run the batch file OSGeo4W-dev.bat you created before. On the command prompt run: devenv
From MSVC, open the solution file
d:\OSGeo4W64\QGIS\ms-windows\osgeo4w\build-qgis-test-x86_64\qgis.sln
Try to build the solution go grab a cup of tea, it may take a (while).
If it fails, run it again and again until there are [hopefully] no errors.
Running QGIS from within MSVC:
Edit the properties of the project ALL_BUILD:
Debugging -> Command -> D:\OSGeo4W64\QGIS\ms-windows\osgeo4w\build-qgis-test-x86_64\output\bin\RelWithDebInfo\qgis.exe
Run.
Ignore the "These projects are out of date" message, it appeares even if no files were was changed.
Old alternative method that might still work using cmake-gui:
Create a 'build' directory somewhere. This will be where all the build output
will be generated.
Now run cmake-gui (still from cmd) and in the Where is the source code:
box, browse to the top level QGIS directory.
In the Where to build the binaries: box, browse to the 'build' directory you
created.
If the path to bison and flex contains blanks, you need to use the short name
for the directory (i.e. C:\Program Files should be rewritten to
C:\Progra~n, where n is the number as shown in `dir /x C:\``).
Verify that the 'BINDINGS_GLOBAL_INSTALL' option is not checked, so that python
bindings are placed into the output directory when you run the INSTALL target.
Hit Configure to start the configuration and select Visual Studio 9 2008
and keep native compilers and click Finish.
The configuration should complete without any further questions and allow you to
click Generate.
Now close cmake-gui and continue on the command prompt by starting
vcexpress. Use File / Open / Project/Solutions and open the
qgis-x.y.z.sln File in your project directory.
Change Solution Configuration from Debug to RelWithDebInfo (Release
with Debug Info) or Release before you build QGIS using the ALL_BUILD
target (otherwise you need debug libraries that are not included).
After the build completed you should install QGIS using the INSTALL target.
Install QGIS by building the INSTALL project. By default this will install to
c:\Program Files\qgis<version> (this can be changed by changing the
CMAKE_INSTALL_PREFIX variable in cmake-gui).
You will also either need to add all the dependency DLLs to the QGIS install
directory or add their respective directories to your PATH.
4.1.4. Packaging
================
To create a standalone installer there is a perl script named 'creatensis.pl'
in 'qgis/ms-windows/osgeo4w'. It downloads all required packages from OSGeo4W
and repackages them into an installer using NSIS.
The script can be run on both Windows and Linux.
On Debian/Ubuntu you can just install the 'nsis' package.
NSIS for Windows can be downloaded at:
http://nsis.sourceforge.net
And Perl for Windows (including other requirements like 'wget', 'unzip', 'tar'
and 'bzip2') is available at:
http://cygwin.com
4.1.5. Packaging your own build of QGIS
=======================================
Assuming you have completed the above packaging step, if you want to include
your own hand built QGIS executables, you need to copy them in from your
windows installation into the ms-windows file tree created by the creatensis
script.
cd ms-windows/
rm -rf osgeo4w/unpacked/apps/qgis/*
cp -r /tmp/qgis1.7.0/* osgeo4w/unpacked/apps/qgis/
Now create a package.
./quickpackage.sh
After this you should now have a nsis installer containing your own build
of QGIS and all dependencies needed to run it on a windows machine.
4.1.6. Osgeo4w packaging
========================
The actual packaging process is currently not documented, for now please take a
look at:
ms-windows/osgeo4w/package.cmd
4.2. Building using MinGW
=========================
Note: This section might be outdated as nowadays Visual C++ is use to build
the "official" packages.
Note: For a detailed account of building all the dependencies yourself you
can visit Marco Pasetti's website here:
http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html
Read on to use the simplified approach with pre-built libraries...
4.2.1. MSYS
===========
MSYS provides a unix style build environment under windows. We have created a
zip archive that contains just about all dependencies.
Get this:
http://download.osgeo.org/qgis/win32/msys.zip
and unpack to c:\msys
If you wish to prepare your msys environment yourself rather than using
our pre-made one, detailed instructions are provided elsewhere in this
document.
4.2.2. Qt
=========
Download Qt opensource precompiled edition exe and install (including the
download and install of mingw) from here:
http://qt.nokia.com/downloads/
When the installer will ask for MinGW, you don't need to download and install
it, just point the installer to c:\msys\mingw
When Qt installation is complete:
Edit C:\Qt\5.9.1\bin\qtvars.bat and add the following lines:
set PATH=%PATH%;C:\msys\local\bin;c:\msys\local\lib
set PATH=%PATH%;"C:\Program Files\Subversion\bin"
I suggest you also add C:\Qt\5.9.1\bin\ to your Environment Variables Path in
the windows system preferences.
If you plan to do some debugging, you'll need to compile debug version of Qt:
C:\Qt\5.9.1\bin\qtvars.bat compile_debug
Note: there is a problem when compiling debug version of Qt 4.7, the script ends with
this message "mingw32-make: *** No rule to make target `debug'. Stop.". To
compile the debug version you have to go out of src directory and execute the
following command:
c:\Qt\5.9.1 make
4.2.3. Flex and Bison
=====================
Get Flex
http://sourceforge.net/project/showfiles.php?group_id=23617&package_id=16424
(the zip bin) and extract it into c:\msys\mingw\bin
4.2.4. Python
=============
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 PyQt5 from sources as
their installer doesn't include some development files which are necessary.
Note that even if you compile without the Python bindings, Python3 is still
a necessary dependency for building QGIS.
4.2.4.1. Download and install Python - use Windows installer
============================================================
(It doesn't matter to what folder you'll install it)
http://python.org/download/
4.2.4.2. Download SIP and PyQt5 sources
=======================================
http://www.riverbankcomputing.com/software/sip/download
http://www.riverbankcomputing.com/software/pyqt/download
Extract each of the above zip files in a temporary directory. Make sure
to get versions that match your current Qt installed version.
4.2.4.3. Compile SIP
====================
c:\Qt\5.9.1\bin\qtvars.bat
python configure.py -p win32-g++
make
make install
4.2.4.4. Compile PyQt
=====================
c:\Qt\5.9.1\bin\qtvars.bat
python configure.py
make
make install
4.2.4.5. Final python notes
===========================
/!\ You can delete the directories with unpacked SIP and PyQt5 sources after a
successful install, they're not needed anymore.
4.2.5. git
==========
In order to check out QGIS sources from the repository, you need a git client.
This installer should work fine:
https://git-scm.com/download/win
4.2.6. CMake
============
CMake is build system used by QGIS. Download it from here:
https://cmake.org/files/v3.9/cmake-3.9.3-win64-x64.msi
4.2.7. QGIS
===========
Start a cmd.exe window ( Start -> Run -> cmd.exe ) Create development
directory and move into it
md c:\dev\cpp
cd c:\dev\cpp
Check out sources from GIT:
git clone git:/qgis/QGIS.git
4.2.8. Compiling
================
As a background read the generic building with CMake notes at the end of
this document.
Start a cmd.exe window ( Start -> Run -> cmd.exe ) if you don't have one
already. Add paths to compiler and our MSYS environment:
c:\Qt\5.9.1\bin\qtvars.bat
For ease of use add c:\Qt\5.9.1\bin\ to your system path in system
properties so you can just type qtvars.bat when you open the cmd console.
Create build directory and set it as current directory:
cd c:\dev\cpp\qgis
md build
cd build
4.2.9. Configuration
====================
cmakesetup ..
Note: You must include the '..' above.
Click 'Configure' button. When asked, you should choose 'MinGW Makefiles' as
generator.
There's a problem with MinGW Makefiles on Win2K. If you're compiling on this
platform, use 'MSYS Makefiles' generator instead.
All dependencies should be picked up automatically, if you have set up the
Paths correctly. The only thing you need to change is the installation
destination (CMAKE_INSTALL_PREFIX) and/or set 'Debug'.
For compatibility with NSIS packaging scripts I recommend to leave the install
prefix to its default c:\program files\
When configuration is done, click 'OK' to exit the setup utility.
4.2.10. Compilation and installation
====================================
make make install
4.2.11. Run qgis.exe from the directory where it's installed (CMAKE_INSTALL_PREFIX)
===================================================================================
Make sure to copy all .dll:s needed to the same directory as the qgis.exe
binary is installed to, if not already done so, otherwise QGIS will complain
about missing libraries when started.
A possibility is to run qgis.exe when your path contains c:\msys\local\bin and
c:\msys\local\lib directories, so the DLLs will be used from that place.
4.2.12. Create the installation package: (optional)
===================================================
Download and install NSIS from (http://nsis.sourceforge.net/Main_Page)
Now using windows explorer, enter the win_build directory in your QGIS source
tree. Read the READMEfile there and follow the instructions. Next right click
on qgis.nsi and choose the option 'Compile NSIS Script'.
4.3. Creation of MSYS environment for compilation of QGIS
=========================================================
4.3.1. Initial setup
====================
4.3.1.1. 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).
4.3.1.2. 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.
4.3.1.3. 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
4.3.2. Installing dependencies
==============================
4.3.2.1. 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
4.3.2.2. 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 --with-postgres=yes --with-postgres-includes=/local/pgsql/include --with-pgsql-libs=/local/pgsql/lib --with-opengl=windows --with-fftw \
--with-freetype --with-freetype-includes=/mingw/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://grass.gdf-hannover.de/wiki/WinGRASS_Current_Status
- http://geni.ath.cx/grass.html
4.3.2.3. 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
4.3.2.4. 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
4.3.2.5. GSL
============
Download sources:
