<H1>2. Overview</H1>
<P>
QGIS, like a number of major projects (e.g., KDE 4.0), uses CMake
(<A HREF="http://www.cmake.org">http://www.cmake.org</A>) for building from source.
</P>
<P>
Following a summary of the required dependencies for building:
</P>
<P>
Required build tools:
</P>
<UL>
<LI>CMake >= 3.0.0
<LI>Flex >= 2.5.6
<LI>Bison >= 2.4
</UL>
<P>
Required build dependencies:
</P>
<UL>
<LI>Qt >= 5.3.0
<LI>Proj >= 4.4.x
<LI>GEOS >= 3.4
<LI>Sqlite3 >= 3.0.0
<LI>SpatiaLite >= 4.2.0
<LI>libspatialindex
<LI>GDAL/OGR >= 2.1
<LI>Qwt >= 5.0 & (< 6.1 with internal QwtPolar)
<LI>expat >= 1.95
<LI>QScintilla2
<LI>QCA
<LI>qtkeychain (>= 0.5)
<LI>libzip
</UL>
<P>
Optional dependencies:
</P>
<UL>
<LI>for GRASS providers and plugin - GRASS >= 7.0.0.
<LI>for georeferencer - GSL >= 1.8
<LI>for PostGIS support - PostgreSQL >= 8.0.x
<LI>for gps plugin - gpsbabel
<LI>for mapserver export and PyQGIS - Python >= 3.3
<LI>for python support - SIP >= 4.12, PyQt >= 5.3 must match Qt version, Qscintilla2
<LI>for qgis mapserver - FastCGI
<LI>for oracle provider - Oracle OCI library
</UL>
<P>
Indirect dependencies:
</P>
<P>
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 <A HREF="http://gdal.org/formats_list.html">http://gdal.org/formats_list.html</A> ff. for instructions how to include
those formats in GDAL.

<H1>3. Building on GNU/Linux</H1>
<A NAME="toc4"></A>
<H2>3.1. Building QGIS with Qt 5.x</H2>
<P>
<B>Requires:</B> Ubuntu / Debian derived distro
</P>
<P>
/!\ <B>Note:</B> 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.
</P>
<P>
These notes are for Ubuntu - other versions and Debian derived distros may
require slight variations in package names.
</P>
<P>
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 <B>*all*</B>
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!
</P>
<P>
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.
</P>
<A NAME="toc5"></A>
<H2>3.2. Prepare apt</H2>
<P>
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:
</P>
<OL>
<LI>Edit your /etc/apt/sources.list file.
<LI>Uncomment all the lines starting with "deb"
</OL>
<P>
Also you will need to be running Ubuntu 'precise' or higher in order for
all dependencies to be met.
</P>
<P>
Now update your local sources database:

<P>
(extracted from the control.in file in <CODE>debian/</CODE>)
</P>
<P>
See <A HREF="http://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu">http://qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu</A> for
currently supported distributions (plain xenial's GDAL for instance is to old
and we build with GDAL2 from ubuntugis).
</P>
<A NAME="toc7"></A>
<H2>3.4. Setup ccache (Optional, but recommended)</H2>
<P>
You should also setup ccache to speed up compile times:
</P>
<div class="code"><PRE>
cd /usr/local/bin
sudo ln -s /usr/bin/ccache gcc
sudo ln -s /usr/bin/ccache g++
</PRE></div>
<P>
or simply add <CODE>/usr/lib/ccache</CODE> to your <CODE>PATH</CODE>.
</P>
<A NAME="toc8"></A>
<H2>3.5. Prepare your development environment</H2>
<P>
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:
</P>
<div class="code"><PRE>
mkdir -p ${HOME}/dev/cpp
cd ${HOME}/dev/cpp
</PRE></div>
<P>
This directory path will be assumed for all instructions that follow.
</P>
<A NAME="toc9"></A>
<H2>3.6. Check out the QGIS Source Code</H2>
<P>
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.
</P>
<P>
1. Anonymous Checkout
</P>
<div class="code"><PRE>
cd ${HOME}/dev/cpp
git clone git://github.com/qgis/QGIS.git
</PRE></div>
<P>
2. Developer Checkout
</P>
<div class="code"><PRE>
cd ${HOME}/dev/cpp
git clone git@github.com:qgis/QGIS.git
</PRE></div>
<A NAME="toc10"></A>
<H2>3.7. Starting the compile</H2>
<P>
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:
</P>
<div class="code"><PRE>
mkdir -p ${HOME}/apps
</PRE></div>
<P>
Now we create a build directory and run ccmake:
</P>
<div class="code"><PRE>
cd QGIS
mkdir build-master
cd build-master
ccmake ..
</PRE></div>
<P>
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.
</P>
<P>
/!\ <B>Warning:</B> Make sure that your build directory is completely empty when you
enter the command. Do never try to "re-use" an existing <B>Qt4</B> 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.
</P>
<P>
Now on with the build:
</P>
<div class="code"><PRE>
make -jX
</PRE></div>
<P>
where X is the number of available cores. Depending on your platform,
this can speed up the build time considerably.
</P>
<P>
Then you can directly run from the build directory:
</P>
<div class="code"><PRE>
./output/bin/qgis
</PRE></div>
<P>
Another option is to install to your system:
</P>
<div class="code"><PRE>
make install
</PRE></div>
<P>
After that you can try to run QGIS:
</P>
<div class="code"><PRE>
$HOME/apps/bin/qgis
</PRE></div>
<P>
If all has worked properly the QGIS application should start up and appear
on your screen. If you get the error message "error while loading shared libraries",
execute this command in your shell.
</P>
<div class="code"><PRE>
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${HOME}/apps/lib/
</PRE></div>
<P>
Optionally, if you already know what aspects you want in your custom build
then you can skip the interactive ccmake .. part by using the cmake -D
option for each aspect, e.g.:
</P>
<div class="code"><PRE>
cmake -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=${HOME}/apps ..
</PRE></div>
<P>
Also, if you want to speed your build times, you can easily do it with ninja,
an alternative to make with similar build options.
</P>
<P>
For example, to configure your build you can do either one of:
</P>
<div class="code"><PRE>
ccmake -G Ninja ..
</PRE></div>
<div class="code"><PRE>
cmake -G Ninja -D CMAKE_BUILD_TYPE=Debug -D CMAKE_INSTALL_PREFIX=${HOME}/apps ..
</PRE></div>
<P>
Build and install with ninja:
</P>
<div class="code"><PRE>
ninja (uses all cores by default; also supports the above described -jX option)
ninja install
</PRE></div>
<A NAME="toc11"></A>
<H2>3.8. Building Debian packages</H2>
<P>
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.
</P>
<P>
First you need to install the debian packaging tools once:
</P>
<div class="code"><PRE>
apt-get install build-essential
</PRE></div>
<P>
First you need to create an changelog entry for your distribution. For example
for Ubuntu Precise:
</P>
<div class="code"><PRE>
dch -l ~precise --force-distribution --distribution precise "precise build"
</PRE></div>
<P>
The QGIS packages will be created with:
</P>
<div class="code"><PRE>
dpkg-buildpackage -us -uc -b
</PRE></div>
<P>
/!\ <B>Note:</B> Install <CODE>devscripts</CODE> to get <CODE>dch</CODE>.
</P>
<P>
/!\ <B>Note:</B> If <CODE>dpkg-buildpackage</CODE> complains about unmet build dependencies
you can install them using <CODE>apt-get</CODE> and re-run the command.
</P>
<P>
/!\ <B>Note:</B> If you have <CODE>libqgis1-dev</CODE> installed, you need to remove it first
using <CODE>dpkg -r libqgis1-dev</CODE>. Otherwise <CODE>dpkg-buildpackage</CODE> will complain about a
build conflict.
</P>
<P>
/!\ <B>Note:</B> By default tests are run in the process of building and their
results are uploaded to <A HREF="http://dash.orfeo-toolbox.org/index.php?project=QGIS.">http://dash.orfeo-toolbox.org/index.php?project=QGIS.</A>
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.
</P>
<P>
The packages are created in the parent directory (ie. one level up).
Install them using dpkg. E.g.:
</P>
<div class="code"><PRE>
sudo debi
</PRE></div>
<A NAME="toc12"></A>
<H2>3.9. On Fedora Linux</H2>
<P>
We assume that you have the source code of QGIS ready and created a
new subdirectory called `build` or `build-qt5` in it.
</P>
<H3>3.9.1. Install build dependencies</H3>
<div class="code"><PRE>
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
</PRE></div>
<P>
To build QGIS server additional dependencies are required:
</P>
<div class="code"><PRE>
dnf install fcgi-devel
</PRE></div>
<P>
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.
</P>
<div class="code"><PRE>
cmake ..
</PRE></div>
<P>
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)
</P>
<div class="code"><PRE>
make
</PRE></div>
<P>
Run from the build directory
</P>
<div class="code"><PRE>
./output/bin/qgis
</PRE></div>
<P>
Or install to your system
</P>
<div class="code"><PRE>
make install
</PRE></div>
<H3>3.9.2. Suggested system tweaks</H3>

By default Fedora disables debugging calls from Qt applications. This prevents
the useful debug output which is normally printed when running the unit tests.

<UL>
<LI>bison
<LI>flex
<LI>git
</UL>
<P>
and from OSGeo4W (select <I>Advanced Installation</I>):
</P>
<UL>
<LI>qgis-dev-deps
</UL>
<P>
This will also select packages the above packages depend on.
</P>
<P>
If you install other packages, this might cause issues. Particularly, make sure
<B>not</B> 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 virtuallayer provider.
</P>
<P>
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.
</P>
<H3>4.1.3. Setting up the Visual Studio project with CMake</H3>
<P>
/!\ Consider this section as example. It tends to outdate, when OSGeo4W and
SDKs move on. <CODE>ms-windows/osgeo4w/package-nightly.cmd</CODE> is used for the
nightly builds and constantly updated and hence might contain necessary
updates that are not yet reflected here.
</P>
<P>
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):
</P>
<div class="code"><PRE>
@echo off
set OSGEO4W_ROOT=C:\OSGeo4W
call "%OSGEO4W_ROOT%\bin\o4w_env.bat"
call "%OSGEO4W_ROOT%\bin\py3_env.bat"
call "%OSGEO4W_ROOT%\bin\qt5_env.bat"
set O4W_ROOT=%OSGEO4W_ROOT:\=/%
set LIB_DIR=%O4W_ROOT%
call "C:\Program Files\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" amd64
path %path%;C:\Program Files\Microsoft Visual Studio 14.0\VC\bin
path %PATH%;C:\Program Files\CMake\bin;c:\cygwin\bin
@set GRASS_PREFIX=c:/OSGeo4W/apps/grass/grass-7.2.1
@set INCLUDE=%INCLUDE%;%OSGEO4W_ROOT%\include
@set LIB=%LIB%;%OSGEO4W_ROOT%\lib;%OSGEO4W_ROOT%\lib
set LIB=%LIB%;%OSGEO4W_ROOT%\apps\Qt5\lib;%OSGEO4W_ROOT%\lib
set INCLUDE=%INCLUDE%;%OSGEO4W_ROOT%\apps\Qt5\include;%OSGEO4W_ROOT%\include
@cmd
</PRE></div>
<P>
Start the batch file and on the command prompt checkout the QGIS source from
git to the source directory <CODE>QGIS</CODE>:
</P>
<div class="code"><PRE>
git clone git://github.com/qgis/QGIS.git
</PRE></div>
<P>
Create a 'build' directory somewhere. This will be where all the build output
will be generated.
</P>
<P>
Now run <CODE>cmake-gui</CODE> (still from <CODE>cmd</CODE>) and in the <I>Where is the source code:</I>
box, browse to the top level QGIS directory.
</P>
<P>
In the <I>Where to build the binaries:</I> box, browse to the 'build' directory you
created.
</P>
<P>
If the path to bison and flex contains blanks, you need to use the short name
for the directory (i.e. <CODE>C:\Program Files</CODE> should be rewritten to
<CODE>C:\Progra~n</CODE>, where <CODE>n</CODE> is the number as shown in `dir /x C:\``).
</P>
<P>
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.
</P>
<P>
Hit <CODE>Configure</CODE> to start the configuration and select <CODE>Visual Studio 9 2008</CODE>
and keep <CODE>native compilers</CODE> and click <CODE>Finish</CODE>.
</P>
<P>
The configuration should complete without any further questions and allow you to
click <CODE>Generate</CODE>.
</P>
<P>
Now close <CODE>cmake-gui</CODE> and continue on the command prompt by starting
<CODE>vcexpress</CODE>. Use File / Open / Project/Solutions and open the
qgis-x.y.z.sln File in your project directory.
</P>
<P>
Change <CODE>Solution Configuration</CODE> from <CODE>Debug</CODE> to <CODE>RelWithDebInfo</CODE> (Release
with Debug Info) or <CODE>Release</CODE> before you build QGIS using the ALL_BUILD
target (otherwise you need debug libraries that are not included).
</P>
<P>
After the build completed you should install QGIS using the INSTALL target.
</P>
<P>
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).
</P>
<P>
You will also either need to add all the dependency DLLs to the QGIS install
directory or add their respective directories to your PATH.
</P>
<H3>4.1.4. Packaging</H3>
<P>
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.
</P>
<P>
The script can be run on both Windows and Linux.
</P>
<P>
On Debian/Ubuntu you can just install the 'nsis' package.
</P>
<P>
NSIS for Windows can be downloaded at:
</P>
<BLOCKQUOTE>
<A HREF="http://nsis.sourceforge.net">http://nsis.sourceforge.net</A>

<P>
And Perl for Windows (including other requirements like 'wget', 'unzip', 'tar'
and 'bzip2') is available at:

<H3>4.1.5. Packaging your own build of QGIS</H3>
<P>
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.
</P>
<div class="code"><PRE>
cd ms-windows/
rm -rf osgeo4w/unpacked/apps/qgis/*
cp -r /tmp/qgis1.7.0/* osgeo4w/unpacked/apps/qgis/
</PRE></div>
<P>
Now create a package.
</P>
<div class="code"><PRE>
./quickpackage.sh
</PRE></div>
<P>
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.
</P>
<H3>4.1.6. Osgeo4w packaging</H3>
<P>
The actual packaging process is currently not documented, for now please take a
look at:
</P>
<P>
<I>ms-windows/osgeo4w/package.cmd</I>
</P>

<H2>4.2. Building using MinGW</H2>
<P>
<B>Note:</B> This section might be outdated as nowadays Visual C++ is use to build
the "official" packages.
</P>
<P>
<B>Note:</B> For a detailed account of building all the dependencies yourself you
can visit Marco Pasetti's website here:
</P>
<P>
<A HREF="http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html">http://www.webalice.it/marco.pasetti/qgis+grass/BuildFromSource.html</A>
</P>
<P>
Read on to use the simplified approach with pre-built libraries...
</P>
<H3>4.2.1. MSYS</H3>
<P>
MSYS provides a unix style build environment under windows. We have created a
zip archive that contains just about all dependencies.
</P>
<P>
Get this:
</P>
<P>
<A HREF="http://download.osgeo.org/qgis/win32/msys.zip">http://download.osgeo.org/qgis/win32/msys.zip</A>
</P>
<P>
and unpack to c:\msys
</P>
<P>
If you wish to prepare your msys environment yourself rather than using
our pre-made one, detailed instructions are provided elsewhere in this
document.
</P>
<H3>4.2.2. Qt</H3>
<P>
Download Qt opensource precompiled edition exe and install (including the
download and install of mingw) from here:
</P>
<P>
<A HREF="http://qt.nokia.com/downloads/">http://qt.nokia.com/downloads/</A>
</P>
<P>
When the installer will ask for MinGW, you don't need to download and install
it, just point the installer to c:\msys\mingw
</P>
<P>
When Qt installation is complete:
</P>
<P>
Edit C:\Qt\5.9.1\bin\qtvars.bat and add the following lines:
</P>
<div class="code"><PRE>
set PATH=%PATH%;C:\msys\local\bin;c:\msys\local\lib
set PATH=%PATH%;"C:\Program Files\Subversion\bin"
</PRE></div>
<P>
I suggest you also add C:\Qt\5.9.1\bin\ to your Environment Variables Path in
the windows system preferences.
</P>
<P>
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
</P>
<P>
