* How to build Qt ?
+
== CHECKOUT slicer source files ==
  
Configure options common to all platform:
+
Two options: <code>svn</code>  or    <code>git-svn</code>
  
Check our different tutorials:
+
To make '''review''' and '''integration''' of your welcome contributions, we recommends the use of <code>git-svn</code>
* Build Qt on Windows
+
 
** Using the Qt Designer on Windows requires that the Slicer and CTK widget plugins are [http://doc.trolltech.com/4.6/deployment-plugins.html#debugging-plugins|compiled in the same mode than Qt]. If Qt was compiled in Release mode (default), Slicer would have to be compiled in Release mode as well. However if Qt is compiled in Debug mode only, Slicer has to be compiled in Debug too. When Qt is in "Release and Debug" mode only the Release version of Designer.exe is generated, Slicer would have to be compiled in Release. So for developers, the <b>Debug mode is recommended</b>, this is why we detail the compilation of Qt below.
+
<br>
*# Use a windows extracter to unzip the [#Prerequisites|Qt zip archive], don't use cygwin unzip it.
+
{{ambox
*# launch the msvc2008 command prompt (MSVC08->Tools->Visual Studio 2008 CommandPrompt) (or: launch cmd.exe and run <code>vcvars32.bat</code>)
+
| type  = warning
*# build with <code>configure.exe -platform win32-msvc2008 -debug</code>  
+
| text  = While it is not enforced, we strongly recommend you to '''AVOID''' the use of '''SPACES''' for both the <code>source directory</code> and the <code>build directory</code>. We mean it.
*#* When asked, choose open source license type (o), then accept the license (y)
+
}}
*#* Note: the option <code>-prefix<code> doesn't work on Windows.
+
<br>
*#* Note: According to [http://qt.nokia.com/doc/4.6/supported-platforms.html] Qt does not support msvc2008 on windows xp.  However, running <code>configure.exe</code> with no <code>-platform</code> argument seems to work. If you run configure with the <code>-platform</code> argument first by mistake, and if <code>configure -clean</code> doesn't work, then you may need to start from a fresh extraction from the .zip archive before running <code>configure.exe</code> again with no <code>-platform</code>, unless you can run <code>nmake</code> with the config clean target.
+
 
*# run <code>nmake</code>.
+
Note that even if you use <code>svn</code> to check out Slicer source code, you will need to have <code>git</code> installed to checkout and build other libraries. '''YES''', you need to install the things listed in the [[Documentation/{{documentation/version}}/Developers/Build Instructions/Prerequisites|prerequisites]] !.
** Note: building with webkit support requires that <i>src/3rdparty/webkit/WebCore/tmp/moc/{debug,release}_shared/mocinclude.tmp</i> be removed. else you will get linker errors like <code>QNetworkReplyHandler.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall WebCore::FormDataIODevice::metaObject(void)const (?metaObject@FormDataIODevice@WebCore@@UBEPBUQMetaObject@@XZ)</code>
+
 
** Note: If you encounter the following error <code>api\qscriptextensionplugin.h(43): Error: Undefined interface,</code>, delete the files <i>\src\script\tmp\moc\debug_shared\mocinclude.tmp</i> and <i>\src\script\tmp\moc\release_shared\mocinclude.tmp</i> and restart nmake. For more info, please see [http://bugreports.qt.nokia.com/browse/QTBUG-6470 QTBug 6470]].
+
 
* Build Qt on Linux
+
=== Using <code>git-svn</code> ===
Downloading the binaries of Qt works fine with Linux, you do not have to compile Qt manually.
+
 
** Note: You need to install the libQtWebkit-devel package too
+
  git clone git://github.com/Slicer/Slicer.git
The following descriptions are given for people who want to  
+
  cd Slicer
compile Qt anyway.
+
  git svn init http://svn.slicer.org/Slicer4/trunk
 +
  git update-ref refs/remotes/git-svn refs/remotes/origin/master
 +
  git checkout master
 +
  git svn rebase
 +
 
 +
Consider reading the following page: [[Slicer:git-svn|Slicer guide to <code>git-svn</code>]]
 +
 
 +
=== Using <code>svn</code> ===
 +
 
 +
cd MyProjects
 +
svn co [http://svn.slicer.org/Slicer4/trunk http://svn.slicer.org/Slicer4/trunk] Slicer4
 +
 
 +
<br><br><br><br>
 +
 
 +
== CONFIGURE and generate Slicer solution files ==
 +
You can configure and generate Slicer solution files using either <code>ccmake</code> or <code>cmake-gui</code>.
 +
=== Per-platform instructions===
 +
==== Windows ====
 +
*'''Recommended''': <code>cmake-gui</code>
 +
** Configure using default options.
 +
* '''Remarks''':
 +
#If you downloaded the Qt binary then <code>qmake</code> will be detected and all paths will be set automatically. 
 +
#If you built your own Qt (e.g. in Debug mode for use with the designer) set the <code>QT_QMAKE_EXECUTABLE</code> in <code>cmake-gui</code>.<code>QT_QMAKE_EXECUTABLE</code> should be set to the path of the qmake.exe file, which is inside the bin directory (for example, <code>/path/to/qt-everywhere-opensource-build-4.7.4/bin/qmake.exe</code>).  
 +
#Windows doesn't support path longer than 260 characters, please make sure that the total path name of your <code>Slicer-build</code> directory is no longer than 50 characters ( for example <code>c:\work\Slicer\Slicer-Superbuild</code> (32 characters) is fine)
 +
 
 +
==== Unix-like ====
 +
*'''Recommended''': <code>ccmake</code>
 +
** Configure using the following commands. By default '''CMAKE_BUILD_TYPE''' is set to '''Debug'''.
 
<pre>
 
<pre>
mkdir Qt
+
mkdir Slicer4-SuperBuild-Debug
mkdir Qt-build
+
cd Slicer4-SuperBuild-Debug
cd Qt
+
ccmake -DQT_QMAKE_EXECUTABLE:FILEPATH=/path/to/QtSDK-1.2/Desktop/Qt/474/gcc/bin/qmake ../Slicer4
wget http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.2.tar.gz
 
tar xvfz qt-everywhere-opensource-src-4.6.2.tar.gz
 
cd qt-everywhere-opensource-src-4.6.2
 
echo yes | ./configure -prefix ../../Qt-build -debug-and-release -opensource  -no-qt3support
 
make -j 16
 
make install
 
 
</pre>
 
</pre>
** Note: On a 64 bit system, you may have to add <code>-arch x86_64</code> to the Qt configure command line (?)
+
* '''Remarks''':
 +
# Using top-level directory name like <code>Slicer-Superbuild-Release</code> or <code>Slicer-Superbuild-Debug</code> is recommended.
 +
 
 +
=== General information ===
 +
 
 +
Two projects are generated by either <code>cmake</code>, <code>ccmake</code> or <code>cmake-gui</code>.
 +
 
 +
One of them is in the top-level bin directory <code>Slicer4-Superbuild</code> and the other one is in the subdirectory <code>Slicer-build</code>:
 +
 
 +
<pre>Slicer4-Superbuild/Slicer-build</pre>
 +
 
 +
# The first project in <code>Slicer4-Superbuild</code> manages all the external dependencies of Slicer (VTK, ITK, Python, ...). To build Slicer for the first time, run make (or build the solution file in Visual Studio) in <code>Slicer4-Superbuild</code>, which will update and build the external libraries and if successful will then build the subproject Slicer-build.<br>
 +
# The second project in <code>Slicer4-Superbuild/Slicer-build</code> is the "traditional" build directory of Slicer.  After local changes in Slicer (or after an svn update on the source directory of Slicer), only running make (or building the solution file in Visual Studio) in <code>Slicer4-Superbuild/Slicer-build</code> is necessary (the external libraries are considered built and up to date). <br>
 +
#'''Warning''': An important amount of disk space is required to compile Slicer in Debug (>10GB on Windows)
 +
 
 +
=== Workaround firewall blocking git protocol ===
 +
* Some firewall will be blocking the git protocol, a possible workaround is to configure Slicer disabling the option <code>Slicer_USE_GIT_PROTOCOL</code>. Then http protocol will be used instead. Consider also reading https://github.com/commontk/CTK/issues/33
 +
 
 +
=== Notes for advanced users ===
 +
* By default, if CMake finds Java on your machine, it automatically builds Java CLIs. If you don't want any Java in your Slicer (or if you don't want to install Java on your Mac Os X), you can pass <code>-DCMAKE_DISABLE_FIND_PACKAGE_Java:BOOL=TRUE</code> when configuring Slicer.
 +
* Same applies for OpenSSL: <code>CMAKE_DISABLE_FIND_PACKAGE_OpenSSL:BOOL=TRUE</code> can be passed when building Slicer for packaging.
 +
 
 +
<br><br><br><br>
 +
 
 +
== BUILD Slicer4 ==
 +
After configuration, start the build process in the  <code>Slicer4-SuperBuild</code> directory
 +
 
 +
=== Per-platform instructions===
 +
==== Windows ====
 +
* Open <code>Slicer4-SuperBuild\Slicer.sln</code> in Visual Studio
 +
* Select your build configuration. Usually '''Release''' of '''Debug'''
 +
* Build the <code>ALL_BUILD</code> project.
 +
 
 +
* If you make local changes to Slicer4, open the solution file located in the directory <code>Slicer4-SuperBuild/Slicer-build</code> instead. You should then be able to either build all projects or just a specific one.
  
* Build Qt on Mac
+
==== Unix-like ====
Same as Linux. Use "-arch x86_64" for a 64 bit build on SnowLeopard.
 
  
== Step1 : Checkout slicer sources using subversion ==
+
  cd ~/Projects/Slicer4-SuperBuild
For example:
+
  make -j<NUMBEROFCORES>
<pre>
+
 
cd MyProjects
+
 
svn co http://svn.slicer.org/Slicer4/trunk Slicer4
+
<br><br><br><br>
</pre>
+
 
 +
== RUN Slicer ==
 +
=== Per-platform instructions===
 +
==== Windows ====
 +
 
 +
Run <code>Slicer4-SuperBuild/Slicer-build/Slicer.exe</code>
 +
 
 +
==== Unix-like ====
 +
 
 +
Run <code>Slicer4-SuperBuild/Slicer-build/Slicer</code>
 +
 
 +
<br><br><br><br>
 +
 
 +
== DEBUG Slicer ==
 +
=== Per-platform instructions===
 +
==== Windows ====
 +
* Make sure you build Slicer using the '''Debug''' configuration.
 +
* Open a windows terminal <code>cmd.exe</code>
 +
* Execute the following command:
 +
  cd \path\to\Slicer4-SuperBuild\Slicer-build
 +
  Slicer.exe --VisualStudio Slicer.sln
 +
 
 +
==== Unix-like ====

''What is the difference between Python and PythonQt build ?''
 
'''The Python option is an older slicer3 flag used to turn on the KWWidgets-based Python option and should not be used with Qt.  PythonQt refers to [http://pythonqt.sourceforge.net the PythonQt Project] which is being integrated with Slicer4.  Leave both options OFF for best results (PythonQt is still being debugged)'''
 
  
== Step3: Configure, Generate the solution files and Build ==
+
<br><br><br><br>
Two projects are generated by ccmake/cmake-gui: the top-level bin directory Slicer3-Superbuild and the subdirectory Slicer3-Superbuild/Slicer3-build.
 
The first project in Slicer3-Superbuild manages all the external dependencies of Slicer (VTK, ITK, Python, ...). Running make (or building the solution file on Visual Studio) will update and build the external libraries and if successful will then build the subproject Slicer3-build.<br>
 
The second project in Slicer3-Superbuild/Slicer3-build is the "traditional" build directory of Slicer. Running make will only build Slicer (the external libaries are considered built and up to date).<br>
 
To build Slicer the first time, run <code>make</code> in Slicer3-Superbuild. After local changes in Slicer (or after an svn update on the source directory of Slicer3), only running make in Slicer3-Superuild/Slicer3-build is necessary.<br>
 
Warning, a lot of space disk is necessary to compile Slicer (>10Go on Windows)

PREREQUISITES


To avoid
Common errors,
we
STRONGLY
recommend to read the
Prerequisites
section.





CHECKOUT slicer source files

Two options: svn or git-svn

To make review and integration of your welcome contributions, we recommends the use of git-svn



Note that even if you use svn to check out Slicer source code, you will need to have git installed to checkout and build other libraries. YES, you need to install the things listed in the prerequisites !.


Using git-svn

 git clone git://github.com/Slicer/Slicer.git
 cd Slicer
 git svn init http://svn.slicer.org/Slicer4/trunk
 git update-ref refs/remotes/git-svn refs/remotes/origin/master
 git checkout master
 git svn rebase

Consider reading the following page: Slicer guide to git-svn

Using svn

cd MyProjects
svn co http://svn.slicer.org/Slicer4/trunk Slicer4





CONFIGURE and generate Slicer solution files

You can configure and generate Slicer solution files using either ccmake or cmake-gui.

Per-platform instructions

Windows

  • Recommended: cmake-gui
    • Configure using default options.
  • Remarks:
  1. If you downloaded the Qt binary then qmake will be detected and all paths will be set automatically.
  2. If you built your own Qt (e.g. in Debug mode for use with the designer) set the QT_QMAKE_EXECUTABLE in cmake-gui.QT_QMAKE_EXECUTABLE should be set to the path of the qmake.exe file, which is inside the bin directory (for example, /path/to/qt-everywhere-opensource-build-4.7.4/bin/qmake.exe).
  3. Windows doesn't support path longer than 260 characters, please make sure that the total path name of your Slicer-build directory is no longer than 50 characters ( for example c:\work\Slicer\Slicer-Superbuild (32 characters) is fine)

Unix-like

  • Recommended: ccmake
    • Configure using the following commands. By default CMAKE_BUILD_TYPE is set to Debug.
mkdir Slicer4-SuperBuild-Debug
cd Slicer4-SuperBuild-Debug
ccmake -DQT_QMAKE_EXECUTABLE:FILEPATH=/path/to/QtSDK-1.2/Desktop/Qt/474/gcc/bin/qmake ../Slicer4
  • Remarks:
  1. Using top-level directory name like Slicer-Superbuild-Release or Slicer-Superbuild-Debug is recommended.

General information

Two projects are generated by either cmake, ccmake or cmake-gui.

One of them is in the top-level bin directory Slicer4-Superbuild and the other one is in the subdirectory Slicer-build:

Slicer4-Superbuild/Slicer-build
  1. The first project in Slicer4-Superbuild manages all the external dependencies of Slicer (VTK, ITK, Python, ...). To build Slicer for the first time, run make (or build the solution file in Visual Studio) in Slicer4-Superbuild, which will update and build the external libraries and if successful will then build the subproject Slicer-build.
  2. The second project in Slicer4-Superbuild/Slicer-build is the "traditional" build directory of Slicer. After local changes in Slicer (or after an svn update on the source directory of Slicer), only running make (or building the solution file in Visual Studio) in Slicer4-Superbuild/Slicer-build is necessary (the external libraries are considered built and up to date).
  3. Warning: An important amount of disk space is required to compile Slicer in Debug (>10GB on Windows)

Workaround firewall blocking git protocol

  • Some firewall will be blocking the git protocol, a possible workaround is to configure Slicer disabling the option Slicer_USE_GIT_PROTOCOL. Then http protocol will be used instead. Consider also reading https://github.com/commontk/CTK/issues/33

Notes for advanced users

  • By default, if CMake finds Java on your machine, it automatically builds Java CLIs. If you don't want any Java in your Slicer (or if you don't want to install Java on your Mac Os X), you can pass -DCMAKE_DISABLE_FIND_PACKAGE_Java:BOOL=TRUE when configuring Slicer.
  • Same applies for OpenSSL: CMAKE_DISABLE_FIND_PACKAGE_OpenSSL:BOOL=TRUE can be passed when building Slicer for packaging.





BUILD Slicer4

After configuration, start the build process in the Slicer4-SuperBuild directory

Per-platform instructions

Windows

  • Open Slicer4-SuperBuild\Slicer.sln in Visual Studio
  • Select your build configuration. Usually Release of Debug
  • Build the ALL_BUILD project.
  • If you make local changes to Slicer4, open the solution file located in the directory Slicer4-SuperBuild/Slicer-build instead. You should then be able to either build all projects or just a specific one.

Unix-like

 cd ~/Projects/Slicer4-SuperBuild
 make -j<NUMBEROFCORES>






RUN Slicer

Per-platform instructions

Windows

Run Slicer4-SuperBuild/Slicer-build/Slicer.exe

Unix-like

Run Slicer4-SuperBuild/Slicer-build/Slicer





DEBUG Slicer

Per-platform instructions

Windows

  • Make sure you build Slicer using the Debug configuration.
  • Open a windows terminal cmd.exe
  • Execute the following command:
 cd \path\to\Slicer4-SuperBuild\Slicer-build
 Slicer.exe --VisualStudio Slicer.sln

Unix-like

NA

make -j4

Details:

A tool returned an error code from "Performing configure step for ..."

Older CMake versions had some problems building complex projects on Windows7 (see more details in: http://cmake.org/Bug/view.php?id=12957). Make sure you use the required CMake version.

A tool returned an error code from "Performing download step (git clone) for ..."

CMake has problems cloning git repositories on Windows7. See more details in http://cmake.org/Bug/view.php?id=12564

If you think the described problem is the same as you have, please add your specific error message to the bug report (the more people report the problem the sooner it will be fixed).
