Qt Creator is a cross-platform C++ IDE for development with the Qt framework.
The binary packages support the following platforms:
Windows 7, Windows XP SP2, Windows Vista
(K)Ubuntu Linux 8.04 (32-bit and 64-bit) or later
Mac OS 10.5 or later
Building the sources requires Qt 4.7.1 or later.
Compiling Qt Creator
* Qt 4.7.1
* On Windows:
- ActiveState Active Perl (version 5.8.9 for Symbian development)
- MinGW 4.4 or later, Visual Studio 2008 or later
The Qt SDK provides you with most of the required software.
* On Mac: XCode 2.5 or later, compiling on 10.4 requires setting the
environment variable QTC_TIGER_COMPAT before running qmake
We recommend that you build Qt Creator not in the source directory, but in a
separate directory. To do that, use the following commands:
make (or mingw32-make or nmake or jom, depending on your platform)
Compiling Qt Quick Designer
Qt Quick Designer (QmlDesigner plugin) depends on "private" headers from Qt
4.7.1, specifically from the QtDeclarative module. These private headers always
end with an "_p.h". Nokia does not promise to keep these files or APIs binary
or source compatible between releases. This means that when compiled, the
plugin has a dependency to the exact Qt version it was compiled with. Running
Qt Creator with the plugin against updated Qt libraries (also for patch
releases) might lead to link time failures, or even crashes.
If you want to disable the plugin, you can pass "QT_PRIVATE_HEADERS=" to qmake:
qmake "QT_PRIVATE_HEADERS=" $SOURCE_DIRECTORY/qtcreator.pro
The plugin is not compiled if the private header files are not found. This
might be the case when you use a Qt version from your distribution, or
installed a self-compiled Qt to a separate directory via 'make install'. You
can fix this by either re-building your Qt with the "-developer-build"
configure option, or by passing the include directory in the source directory
to qmake. For example:
qmake "QT_PRIVATE_HEADERS=$$QT_BUILD_TREE/include" $SOURCE_DIRECTORY/qtcreator.pro
Compiling Qt and Qt Creator on Windows
This section provides step by step instructions for compiling the latest
versions of Qt and Qt Creator on Windows. Alternatively, to avoid having to
compile Qt yourself, you can use one of the versions of Qt shipped with the Qt
SDK (release builds of Qt using MinGW and Visual C++ 2008).
1. Decide which compiler to use: MinGW or Microsoft Visual Studio. If you
plan to contribute to Qt Creator, you should compile your changes with
2. Install msysGit from http://code.google.com/p/msysgit/. If you plan to
use the MinGW compiler suite, do not choose to put git in the
default path of Windows command prompts. For more information, see
3. Create a working directory under which to check out Qt and Qt Creator,
for example, c:\work. If you plan to use MinGW and Microsoft Visual
Studio simultaneously or mix different Qt versions, we recommend
creating a directory structure which reflects that. For example:
4. Download and install Perl from http://www.activestate.com/activeperl
and check that perl.exe is added to the path.
5. In the working directory, check out the respective branch of Qt
(we recommend 4.7; see http://qt.gitorious.org/qt).
6. Check out Qt Creator (master branch, see
You should now have the directories qt and creator under your working
7. Install a compiler:
- For MinGW (4.4 onwards), see http://www.mingw.org/. Note that gcc 4.5
produces insufficient debugging information, and therefore, we
recommend that you use gcc 4.4 for debugging.
- For Microsoft Visual C++, install the Windows SDK and the "Debugging
Tools for Windows" from the SDK image. We strongly recommend using the
64-bit version and 64-bit compilers on 64-bit systems.
When using Visual C++ 2010, you must apply a hotfix that is available
For the Visual C++ compilers, it is recommended to use the tool 'jom'.
It is a replacement for nmake that utilizes all CPU cores and thus
speeds up compilation significantly. Download it from
ftp://ftp.qt.nokia.com/jom/ and add the executable to the path.
8. For convenience, we recommend creating shell prompts with the correct
environment. This can be done by creating a .bat-file
(such as, <working_directory>\qtvars.bat) that contains the environment
A .bat-file for MinGW looks like:
For the Visual C++ compilers, call the .bat file that sets up the
environment for the compiler (provided by the Windows SDK or the
CALL "C:\Program Files (x86)\MSVC10\VC\vcvarsall.bat" amd64
You can create desktop links to the bat files using the working
directory and specifying
%SystemRoot%\system32\cmd.exe /E:ON /V:ON /k <working_directory>\qtvars.bat
9. When using MinGW, open the shell prompt and enter:
That should result in a 'sh is not recognized as internal or external
command...' error. If a sh.exe is found, the compile process will fail.
You have to remove it from the path.
10. You are now ready to configure and build Qt and Qt Creator.
To use MinGW, open the the shell prompt and enter:
configure -debug && mingw32-make -s
qmake && mingw32-make -s
To use the Visual C++ compilers, enter:
configure -debug && jom
qmake && jom
11. To launch Qt Creator, enter:
12. When using Visual C++ with the "Debugging Tools for Windows" installed,
the extension library qtcreatorcdbext.dll to be loaded into the
Windows console debugger (cdb.exe) should have been built under
lib\qtcreatorcdbext32 or lib\qtcreatorcdbext64.
When using a 32 bit-build of Qt Creator with the 64 bit version of the
"Debugging Tools for Windows" the library should also be built with
a 64 bit compiler (rebuild src\libs\qtcreatorcdbext using a 64 bit
Note that unlike on Unix, you cannot overwrite executables that are running.
Thus, if you want to work on Qt Creator using Qt Creator, you need a
separate build of it. We recommend using a separate, release-built version
of Qt and Qt Creator to work on a debug-built version of Qt and Qt Creator
or using shadow builds.
