If you build Slicer on ...
Linux
- Using binary works great for both Debug and Release build of Slicer. See #Download_links
Mac
- Using binary works great for both Debug and Release build of Slicer. See #Download_links
Windows
Debug (32 and 64-bit) or Release (64-bit)
- You have to build Qt from source. See #Download_links
- Details: Using the Qt Designer on Windows requires that the Slicer plugins are in the same mode as 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 Debug mode is recommended, this is why we detail the compilation of Qt below.
Release (32-bit)
- Using binary works great for 32-bit Release build of Slicer. See #Download_links
Download Qt: Source and Binaries

While it is not enforced, we strongly recommend you to USE the recommended version of Qt. We mean it. |
- That said, if you feel like experimenting, nothing prevent you from building against a difference version.
Download links
The following table list the link allowing to download either the recommended source code or binary of Qt.
Linux | Mac | Windows | ||||||
---|---|---|---|---|---|---|---|---|
Tiger | Leopard, SnowLeopard | VS2008 | VS2010 | |||||
32bits | 64bits | 32bits | 64bits | 32bits | 64bits | 32bits | 64bits | |
Qt source link | 4.7.4 | 4.7.4 | 4.7.4 | 4.7.4 | 4.7.4 | |||
Qt binary link | SDK-1.2 | SDK-1.2 | carbon_4.7.0 | cocoa_4.7.4 | 4.7.4 | - | 4.7.4 | - |
Qt version specific issues
Qt 4.6 on mac: hard to compile (tbd: be more specific)
Qt 4.6.x on windows (and possibly in linux/mac): No image base64 support in QLabel/QTooltips (work around exists though)
Qt 4.7 on mac: click outside of popup (http://na-mic.org/Mantis/view.php?id=1241) Fixed in Qt 4.8 ?
Qt 4.7.3 in mac: http://na-mic.org/Mantis/view.php?id=1388 (fixed in Qt 4.7.4)
Qt 4.8 does not work with PythonQt in slicer4 - suggested version is 4.7.4
How to change the minimum required version ?
- It's indeed possible to use a different version, just be aware that moving forward in time, things may not work as expected. Even worse Slicer may simply fail to compile.
- By configuring Slicer using
-DSlicer_REQUIRED_QT_VERSION:STRING=4.7.0
, you will be able to change the minimum required version.
- See 898bb14e, r19698, Mailing list
Build instructions
![]() |
Please, make sure that your IDE/compiler is properly installed and that all associated ServicePack are also installed. See Prerequisites. |
Linux
- Consider installing the following optional packages (
libxt-dev libxrender-dev libxrandr-dev libxinerama-dev libxcursor-dev libfontconfig-dev libglib2.0-dev
)
mkdir qt-everywhere-opensource-build-4.7.4 tar xvfz qt-everywhere-opensource-src-4.7.4.tar.gz cd qt-everywhere-opensource-src-4.7.4 ./configure -prefix ../qt-everywhere-opensource-build-4.7.4 -debug-and-release -opensource -confirm-license -no-qt3support -webkit make -j8 make install
Note: Adapt -j8
with the number of core on your machine, a dual core should probably not do more than -j3
, an 8 core machine can resonably go as much as -j12
.
Mac
Similar to Linux configuration. Note that -arch x86_64
has been added.
mkdir qt-everywhere-opensource-build-4.7.4 tar xvfz qt-everywhere-opensource-src-4.7.4.tar.gz cd qt-everywhere-opensource-src-4.7.4 ./configure -prefix ../qt-everywhere-opensource-build-4.7.4 -debug-and-release -opensource -confirm-license -no-qt3support -webkit -arch x86_64 make -j8 make install
- Consider reading: http://doc.qt.nokia.com/4.7/developing-on-mac.html)
Windows
- Use a windows extracter to unzip the Qt zip archive, don't use cygwin unzip it.
- launch the msvc2008 command prompt (MSVC08->Tools->Visual Studio 2008 CommandPrompt) (or: launch cmd.exe and run
vcvars32.bat
) Note: Start x64 prompt from Start menu (don't start from inside visual studio or it will be an x86 32 bit shell). Menu item is "Visual Studio 2008 x64 Win64 Command Prompt" - build with
configure.exe -platform win32-msvc2008 -debug
- When asked, choose open source license type (o), then accept the license (y)
- Note: the option
-prefix
doesn't work on Windows. - Note: According to [1] Qt does not support msvc2008 on windows xp. However, running
configure.exe
with no-platform
argument seems to work. If you run configure with the-platform
argument first by mistake, and ifconfigure -clean
doesn't work, then you may need to start from a fresh extraction from the .zip archive before runningconfigure.exe
again with no-platform
, unless you can runnmake
with the config clean target. - Note: for Microsoft Visual Studio 2010 users, Qt 4.6.3 is hard to configure with MSVC2010, use Qt 4.7.x instead. Build with
set QMAKESPEC=win32-msvc2010
andconfigure -platform win32-msvc2010 -debug
- run
nmake
- Note: building with webkit support requires that src/3rdparty/webkit/WebCore/tmp/moc/{debug,release}_shared/mocinclude.tmp be removed. else you will get linker errors like
QNetworkReplyHandler.obj : error LNK2001: unresolved external symbol "public: virtual struct QMetaObject const * __thiscall WebCore::FormDataIODevice::metaObject(void)const (?metaObject@FormDataIODevice@WebCore@@UBEPBUQMetaObject@@XZ)
- Note: If you encounter the following error
api\qscriptextensionplugin.h(43): Error: Undefined interface,
, delete the files \src\script\tmp\moc\debug_shared\mocinclude.tmp and \src\script\tmp\moc\release_shared\mocinclude.tmp and restart nmake. For more info, please see QTBug 6470].
