2. Overview

QGIS, like a number of major projects (e.g., KDE 4.0), uses CMake for building from source.

Following a summary of the required dependencies for building:

Required build tools:

CMake >= 3.12.0
Flex >= 2.5.6
Bison >= 2.4
Python >= 3.7

Required build dependencies:

Qt >= 5.15.2
Proj >= 7.2.0
GEOS >= 3.9
Sqlite3 >= 3.0.0
SpatiaLite >= 4.2.0
libspatialindex
GDAL/OGR >= 3.2.0
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 >= 3.6
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 format list 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

You will need a recent enough distribution in order for all dependencies to be met. The supported distributions are listed in the following section.

Now update your local sources database:

sudo apt-get update

3.3. Install build dependencies

(extracted from the control.in file in debian/)

See debian-ubuntu for currently supported distributions (plain xenial's GDAL for instance is too old and we build with GDAL2 from ubuntugis).

To build QGIS server landing page/catalog webapp additional dependencies are required:

Node.js (current LTS recommended): https://nodejs.org/en/download/
Yarn Package Manager: https://yarnpkg.com/getting-started/install

Additionally, the cmake flag WITH_SERVER_LANDINGPAGE_WEBAPP needs to be turned on.

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/, 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.

Anonymous Checkout

cd ${HOME}/dev/cpp
git clone https://github.com/qgis/QGIS.git

Developer Checkout

cd ${HOME}/dev/cpp
git clone git@github.com: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 package manager for example), set the CMAKE_INSTALL_PREFIX to somewhere you have write access to (For example ${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 Qt5 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.

sudo ldconfig

If that doesn't help add the install path to LD_LIBRARY_PATH:

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

To build even faster, you can build just the targets you need using, for example:

ninja qgis
ninja pycore
# if it's on desktop related code only:
ninja qgis_desktop

3.7.1 Available compilation flags

QGIS build is tunable according to your needs. Many flags are available to activate or deactivate some functionalities, here is a subset:

BUILD_WITH_QT6: Enable (experimental) Qt6 support
WITH_3D: Determines whether QGIS 3D library should be built
WITH_ANALYSIS: Determines whether QGIS analysis library should be built
WITH_AUTH: Determines whether QGIS authentication methods should be built
WITH_BINDINGS: Determines whether Python bindings should be built
WITH_COPC: Determines whether Cloud Optimized Point Cloud (COPC) support should be built
WITH_DESKTOP: Determines whether QGIS desktop should be built
WITH_EPT: Determines whether Entwine Point Cloud (EPT) support should be built
WITH_GRASS${GRASS_CACHE_VERSION}: Determines whether GRASS ${GRASS_SEARCH_VERSION} plugin should be built
WITH_GUI: Determines whether QGIS GUI library (and everything built on top of it) should be built
WITH_HANA: Determines whether SAP HANA Spatial support should be built
WITH_ORACLE: Determines whether Oracle support should be built
WITH_PDAL: Determines whether PDAL support should be built
WITH_POSTGRESQL: Determines whether POSTGRESQL support should be built
WITH_QGIS_PROCESS: Determines whether the standalone "qgis_process" tool should be built
WITH_QSPATIALITE: Determines whether QSPATIALITE sql driver should be built
WITH_SERVER: Determines whether QGIS server should be built
WITH_SPATIALITE: Determines whether Spatialite support should be built (required for spatialite, virtual, wfs providers)

A complete list can been extracted from the source code with the following command line:

cmake .. -N -LH | grep -B1 WITH_

3.8. Compiling with 3D

In the cmake, you need to enable:

WITH_3D=True

3.8.1. Compiling with 3D on old Debian based distributions

QGIS 3D requires Qt53DExtras. These headers have been removed from Qt upstream on Debian Buster and Ubuntu focal (20.04) based distributions. A copy has been made in the QGIS repository in external/qt3dextra-headers. To compile with 3D enabled on these distributions, you need to add some cmake options:

CMAKE_PREFIX_PATH={path to QGIS Git repo}/external/qt3dextra-headers/cmake
QT5_3DEXTRA_INCLUDE_DIR={path to QGIS Git repo}/external/qt3dextra-headers
QT5_3DEXTRA_LIBRARY=/usr/lib/x86_64-linux-gnu/libQt53DExtras.so
Qt53DExtras_DIR={path to QGIS Git repo}/external/qt3dextra-headers/cmake/Qt53DExtras

Above instructions do not apply to newer versions of Debian and Ubuntu.

3.9. Building different branches

By using git worktree, you can switch between different branches to use several sources in parallel, based on the same Git configuration. We recommend you to read the documentation about this Git command:

git commit
git worktree add ../my_new_functionality
cd ../my_new_functionality
git fetch qgis/master
git rebase -i qgis/master
# only keep the commits to be pushed
git push -u my_own_repo my_new_functionality

3.10. 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 setup a changelog entry for your distribution. For example for Debian Bookworm:

dch -l ~bookworm --force-distribution --distribution bookworm "bookworm build"

You also need to install the build dependencies. Alternatively use:

debian/rules templates
sudo mk-build-deps -i

The QGIS packages will be created with:

dpkg-buildpackage -us -uc -b

Note: Install devscripts to get dch and mk-build-deps.

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 https://cdash.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

3.10.1. Building packages with Oracle support

To build packages with Oracle support you need the Oracle libraries (currently 21.11) as additional build dependencies:

curl -JLO https://download.oracle.com/otn_software/linux/instantclient/2111000/oracle-instantclient-devel-21.11.0.0.0-1.el8.x86_64.rpm
curl -JLO https://download.oracle.com/otn_software/linux/instantclient/2111000/oracle-instantclient-basiclite-21.11.0.0.0-1.el8.x86_64.rpm
sudo apt install alien

3.11. 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.

To build QGIS server additional dependencies are required:

dnf install fcgi-devel

And for building QGIS server landing page/catalog webapp:

dnf install nodejs yarnpkg

Additionally, the cmake flag WITH_SERVER_LANDINGPAGE_WEBAPP needs to be turned on.

Make sure that your build directory is completely empty when you enter the following command. Do never try to "re-use" an existing Qt5 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

3.11.2. 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

3.11.3. Additional tools for QGIS development

If you're going to be developing QGIS on a Fedora system, the following extra packages are required for the various QGIS source formatting and preparation scripts.

dnf install ag ccache expect ninja-build astyle python3-autopep8 python3-mock python3-nose2 perl-YAML-Tiny

3.11.4. QT6 experimental builds with Fedora Rawhide

This requires latest QGIS master (>= January 25th 2024).

To save ~ 700 MB, if you want to install PROJ without its optional grids, first do:

dnf5 install -y --setopt=install_weak_deps=False proj-devel

Installation of all needed build dependencies:

Distribution Install command for packages

To build,

cmake .. -DBUILD_WITH_QT6=ON -DWITH_QTWEBKIT=OFF -DWITH_QTWEBENGINE=ON

4. Building on Windows

4.1. Building with Microsoft Visual Studio

This section describes how to build QGIS using Visual Studio (MSVC) 2019 on Windows. This is currently also how the binary QGIS packages are made.

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

4.1.1. Visual Studio 2019 Community Edition

Download the free (as in free beer) Community installer

Select "Desktop Development with C++"

4.1.2. Other tools and dependencies

Download and install following packages:

CMake
GNU flex, GNU bison and GIT with cygwin 64bit
OSGeo4W 64bit
ninja: Copy the ninja.exe to C:\OSGeo4W64\bin\

For the QGIS build you need to install following packages from cygwin:

bison
flex
git (even if you already have Git for Windows installed)

and from OSGeo4W (select Advanced Install):

qgis-dev-deps
- This will also select packages the above packages depend on.
- Note: 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.

If you intend to also build all the dependencies, you can refer to the OSGeo4W repository.

4.1.3. Clone the QGIS Source Code

Choose a directory to store the QGIS source code. For example, to put it in the OSGeo4W64 install, navigate there:

cd C:\OSGeo4W64

This directory will be assumed for all instructions that follow.

On the command prompt clone the QGIS source from git to the source directory QGIS:

git clone git://github.com/qgis/QGIS.git

This requires Git. If you have Git for Windows on your PATH already, you can do this from a normal command prompt. If you do not, you can use the Git package that was installed as part of Cygwin by opening a Cygwin[64] Terminal

And, to avoid Git in Windows reporting changes to files not actually modified:

cd QGIS
git config core.filemode false

4.1.4. Configure and build from command line

The best reference for building QGIS can be found in the build scripts for OSGeo4W

4.2. Building on Linux with mingw64

With this approach you can cross build a Windows binary on Linux using mingw64 in a Docker container.

To build on Linux from your QGIS sources directory, launch:

ms-windows/mingw/build.sh

After a successful build, you will find two packages in the QGIS sources directory:

qgis-portable-win64.zip (QGIS for Windows 64bit)
qgis-portable-win64-debugsym.zip (debug symbols)

This method is also used in the continuous integrations process. After each pull request the two packages mentioned above are stored as GitHub actions artifacts and are available for download making it possible to quickly test changes on Windows.

4.2.1. Building with Docker

This is the simplest way, but you need to have Docker installed on your system.

You can use a Docker image to cross build QGIS by calling the script ms-windows/mxe/build.sh from the root directory of QGIS repository.

=== Building without Docker ====

This requires to install mxe toolchain on your system and build all dependencies by yourself.

4.2.1.1. Initial setup

Please follow the instructions on mxe website to setup your building toolchain http://mxe.cc/, take note of the path where you have installed mxe.

4.2.1.2. Building the dependencies

Please see README.md under ms-windows/mxe for detailed instructions and for the list of dependencies that need to be built in mxe before attempting to build QGIS.

4.2.1.3. Cross-Building QGIS

Edit the build-mxe.sh script and optionally adjust the path where your mxe installation is located, you can also change the build and release directories.

4.2.2. Testing QGIS

Copy and unzip on the Windows machine package produced by the build and launch the qgis binary: no installation is required.

5. Building on MacOS X

If you want to test QGIS, easiest option is to download and install all-in-one self-containing bundle directly from

https://qgis.org/downloads/macos

On the other hand, if you want to build or develop QGIS on your own, you need a set of dependencies and tools. These instructions will use the same set of dependencies that are used for all-in-one QGIS bundle, but you can build QGIS with Homebrew, MacPorts or Conda dependencies too.

https://github.com/qgis/QGIS-Mac-Packager

Included are notes for building on latest Mac OS X with latest updates installed. The build uses clang compiler.

Parallel Compilation: On multiprocessor/multicore Macs, it's possible to speed up compilation, but it's not automatic. Whenever you type "make" (but NOT "make install"), instead type:

make -j [#cpus]

Replace [#cpus] with the number of cores and/or processors your Mac has. To find out how many CPUs you have available, run the following in Terminal:

/usr/sbin/sysctl -n hw.ncpu

5.1. Install Developer Tools

Developer tools are not a part of a standard OS X installation. As minimum you require command line tools

sudo xcode-select --install

but installation of Xcode from the App Store is recommended too.

5.2. Install CMake and other build tools

For example install Homebrew

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

and these development/build tools

brew install git cmake ninja pkg-config wget bash-completion curl gnu-sed coreutils ccache libtool astyle help2man autoconf automake pandoc

if you have these tools installed from MacPorts or Conda, it is the same, but we will need to be able to run cmake and others from Terminal in the following steps

5.3. Install Qt5 and QGIS-Deps

To build QGIS, we need Qt5 and FOSS dependencies on hand. The Qt5 version ideally should match the version that was used to build dependency package.

Download the latest QGIS-Deps install script, qt package and QGIS-Deps packages from

https://qgis.org/downloads/macos/deps

You should have one bash script and two tar archive in your download folder. Run the install script to install Qt and QGIS-Deps to /opt/ area. You need root privileges or have write access to /opt/Qt and /opt/QGIS.

Alternatively you can download and install Qt Open Source for MacOS from the

https://www.qt.io/

in the same version as referenced in the install script. It must be installed in /opt/Qt

Note that the QGIS-Deps package is not yet signed, so you may need to add Terminal to System Preferences -> Security & Privacy -> Privacy -> Developer Tools or manually accept usage of the libraries when asked by system.

5.4. QGIS source

Unzip the QGIS source to a working folder of your choice. If you are reading this from the source, you've already done this.

If you want to experiment with the latest development sources, go to the github QGIS project page:

http://github.com/qgis/QGIS

It should default to the master branch. Click the Downloads button and select Download .tar.gz. Double-click the tarball to unzip it.

Alternatively, use git and clone the repository by

git clone git://github.com/qgis/QGIS.git

5.5. Configure the build

CMake supports out of source build so we will create a 'build' dir for the build process. OS X uses ${HOME}/Applications as a standard user app folder (it gives it the system app folder icon). If you have the correct permissions you may want to build straight into your /Applications folder. The instructions below assume you are building into a ${HOME}/Applications directory.

In a Terminal cd to the qgis source folder previously downloaded, then:

cd ..
mkdir build
cd build

QGIS_DEPS_VERSION=0.9;\
QT_VERSION=5.15.2;\
PATH=/opt/QGIS/qgis-deps-${QGIS_DEPS_VERSION}/stage/bin:$PATH;\
cmake \
  -D CMAKE_INSTALL_PREFIX=~/Applications \
  -D CMAKE_BUILD_TYPE=Release \
  -D QGIS_MAC_DEPS_DIR=/opt/QGIS/qgis-deps-${QGIS_DEPS_VERSION}/stage \
  -D CMAKE_PREFIX_PATH=/opt/Qt/${QT_VERSION}/clang_64 \
  ../QGIS

Note: Don't forget the ../QGIS on the last line, which tells CMake to look for the source files.

Note: Double check on the screen output that all libraries are picked from QGIS-Deps /opt/QGIS and not from system /usr/lib or Homebrew's /usr/local/ or system Frameworks /Library/Frameworks/. Especially check Proj, GDAL, sqlite3 and Python paths.

After the initial Terminal configure, you can use ccmake to make further changes:

cd build
ccmake ../QGIS

5.6. Building

Now we can start the build process (remember the parallel compilation note at the beginning, this is a good place to use it, if you can):

make -j [#cpus]

Now you can run the QGIS from build directory by ./output/bin/QGIS.app/Contents/MacOS/QGIS

If all built without errors you can then install it:

make install

or, for an /Applications build:

sudo make install

For running the installed QGIS, you need to keep the dependencies in /opt/ folder in place. If you want to create bundle that runs without these dependencies, please read the documentation in project

https://github.com/qgis/QGIS-Mac-Packager

6. Setting up the WCS test server on GNU/Linux

Requires: Ubuntu / Debian derived distro

These notes are for Ubuntu - other versions and Debian derived distros may require slight variations in package names.

6.1. Preparation

Note the git repo below will change to the default QGIS repo once this work is integrated into master.

git remote add blazek git://github.com/blazek/Quantum-GIS.git
git fetch blazek
git branch --track wcs2 blazek/wcs2
git checkout wcs2
cd /var/www/
sudo mkdir wcs
sudo chown timlinux wcs
cd wcs/
mkdir cgi-bin
cd cgi-bin/

6.2. Setup mapserver

sudo apt-get install cgi-mapserver

Set the contents of /var/www/wcs/cgi-bin/wcstest-1.9.0 to:

#! /bin/sh
MS_MAPFILE=/var/www/wcs/testdata/qgis-1.9.0/raster/wcs.map
export MS_MAPFILE
/usr/lib/cgi-bin/mapserv

Then do:

chmod +x var/www/wcs/cgi-bin/wcstest-1.9.0
mkdir -p /var/www/wcs/testdata/qgis-1.9.0/raster/
cd /var/www/wcs/testdata/qgis-1.9.0/raster/
cp -r /home/timlinux/QGIS/tests/testdata/raster/* .

Edit /var/www/wcs/testdata/qgis-1.9.0/raster/wcs.map and set the shapepath to this:

SHAPEPATH "/var/www/wcs/testdata/qgis-1.9.0/raster"

Then create /var/www/wcs/7-wcs.example.com.conf setting the contents to this:

<VirtualHost*:80>
ServerName wcs.example.com
ServerAdmin wcs-admin@example.com

LogLevel warn
LogFormat "%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" \"%{forensic-id}n\"" combined
CustomLog /var/log/apache2/wcs_example.com/access.log combined
ErrorLog /var/log/apache2/wcs_example.com/error.log

DocumentRoot /var/www/wcs/html

ScriptAlias /cgi-bin/ /var/www/wcs/cgi-bin/
<Directory "/var/www/wcs/cgi-bin">
	AllowOverride None
	Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
	Order allow,deny
	Allow from all
</Directory>

RewriteEngine on
RewriteRule /1.9.0/wcs /cgi-bin/wcstest-1.9.0 [PT]

</VirtualHost>

6.3. Create a home page

mkdir html
vim html/index.html

Set the contents to:

This is the test platform for QGIS' wcs client. You can use these services
from QGIS directly (to try out WCS for example) by pointing your QGIS to:
http://wcs.example.com/1.9.0/wcs

6.4. Now deploy it

sudo mkdir /var/log/apache2/wcs_example.com
sudo chown www-data /var/log/apache2/wcs_example.com
cd /etc/apache2/sites-available/
sudo ln -s /var/www/wcs/7-wcs.example.com.conf .
cd /var/www/wcs/
sudo a2ensite 7-wcs.example.com.conf
sudo /etc/init.d/apache2 reload

6.5. Debugging

sudo tail -f /var/log/apache2/wcs_example.com/error.log

7. Setting up a Jenkins Build Server

Assumption: You know how to make a working build environment and want to deploy it under Jenkins for continuous integration testing now.

These notes are terse, I will expand on them later as the need arises. The procedure is:

Install Jenkins and get it configured according to your own preferences
Make sure you have the git, github, junit etc plugins installed. A complete list of the plugins I have installed follows (note that you almost certainly don't need evey plugin listed here):
- External Monitor Job Type Plugin
- LDAP Plugin
- pam-auth
- javadoc
- ant
- Jenkins Subversion Plug-in
- Git Plugin
- Maven 2 Project Plugin
- Jenkins SLOCCount Plug-in
- Jenkins Sounds plugin
- Jenkins Translation Assistance plugin
- ruby-runtime
- Jenkins CVS Plug-in
- Coverage/Complexity Scatter Plot PlugIn
- Status Monitor Plugin
- Git Parameter Plug-In
- github-api
- GitHub plugin
- Jenkins Violations plugin
- git-notes Plugin
- Twitter plugin
- Jenkins Cobertura Plugin
- Jenkins Gravatar plugin
- Jenkins SSH Slaves plugin
Create a Job called 'QGIS'
Use the following options for your job:
- Job Name: QGIS
- Job Type: Build a free-style software project
- Tick enable project based security (you need to elsewhere configure your Jenkins security to per project settings)
- Allow Anonymous user Read and Discover access
- Set the github project to https://github.com/qgis/QGIS/
- Set source code management to Git
- Set repository url to git://github.com/qgis/QGIS.git
- In advanced repository url settings set refspec to +refs/heads/master:refs/remotes/origin/master
- Set branch to build to master
- Repository Browser: Auto
- Build triggers: set to Poll SCM and set schedule to ***** (polls every minute)
- Build - Execute shell and set shell script to:

cd build
cmake ..
xvfb-run --auto-servernum --server-num=1 \
  --server-args="-screen 0 1024x768x24" \
  make Experimental || true
if [ -f Testing/TAG ] ; then
  xsltproc ../tests/ctest2junix.xsl \
    Testing/`head -n 1 < Testing/TAG`/Test.xml > \
    CTestResults.xml
fi

Add Junit post build action and set 'Publish Junit test result report' to: build/CTestResults.xml
Email notification: Send separate e-mails to individuals who broke the build
Jenkins sounds - set up sounds for Failure, Success and Unstable.
Save

Now open the Job dash board and push something to QGIS and wait a minute to validate automated builds work.

Note: You will need to log in to the Jenkins user account and go to /var/lib/jenkins/jobs/QGIS/workspace, then make a build directory and run the initial cmake setup and then do test build. This process is the same as described elsewhere in this doc.

I based some of the set up from this nice blog article here:

http://alexott.blogspot.com/2012/03/jenkins-cmakectest.html

8. Debug output and running tests

If you are interested in seeing embedded debug output, change the following CMake option:

-D CMAKE_BUILD_TYPE=DEBUG  # (or RELWITHDEBINFO)

This will flood your terminal or system log with lots of useful output from QgsDebugMsg() calls in source code.

Those lines can be reduced or augmented by setting the QGIS_DEBUG runtime environment variable between 0 (no messages) and 5 (all messages).

If you would like to run the test suite, you will need to do so from the build directory, as it will not work with the installed/bundled app. First set the CMake option to enable tests:

-D ENABLE_TESTS=TRUE

Then run all tests from build directory:

cd build
make test

To run all tests and report to http://cdash.orfeo-toolbox.org/index.php?project=QGIS

cd build
make Experimental

You can define the host name reported via 'make Experimental' by setting a CMake option:

-D SITE="my.domain.org"

To run specific test(s) (see 'man ctest'):

cd build
# show listing of tests, without running them
ctest --show-only

# run specific C++ or Python test(s) matching a regular expression
ctest --verbose --tests-regex SomeTestName
