Configure options are common to all platforms.
Check our different tutorials to learn them.
Note: download the pre-compiled Qt unless you know you need to build from source to use the Qt Designer or if you want to make a 64 bit windows build
Build Qt on Windows
- 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.
- Use a windows extracter to unzip the [#Prerequisites|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].
- 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
Build Qt on Linux
- 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.
The following descriptions are given for people who want to compile Qt anyway.
mkdir Qt mkdir Qt-build cd Qt wget http://get.qt.nokia.com/qt/source/qt-everywhere-opensource-src-4.6.3.tar.gz tar xvfz qt-everywhere-opensource-src-4.6.3.tar.gz cd qt-everywhere-opensource-src-4.6.3 echo yes | ./configure -prefix ../../Qt-build -debug-and-release -opensource -no-qt3support make -j8 make install
Note: On a 64 bit system, you may have to add -arch x86_64
to the Qt configure command line (?)
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
.
Build Qt on Mac
Same as Linux. Use the flag -cocoa
on the configure command-line(the -shared
flag should be set automatically); for a 64 bit build on SnowLeopard use -arch x86_64
. For more information go to http://doc.qt.nokia.com/4.6/developing-on-mac.html (warning default values are different: -carbon
vs -cocoa
for Qt 4.7: http://doc.qt.nokia.com/4.7/developing-on-mac.html)
