Qt for Windows - Building from Source
Step 1: Install the License File (Commercially Licensed Qt Only)
If you have a commercial Qt license, download the license file from your Qt Account Web portal and save it to your home directory as
Step 2: Unpack the Archive
Uncompress the files into the directory you want Qt installed; e.g.
Note: The install path must not contain any spaces or Windows specific file system characters.
Step 3: Set the Environment Variables
We recommend creating a desktop link that opens a command prompt with the environment set up similar to the Command Prompt menu entries provided by the Windows SDKs. This is done by creating an application link passing a
.cmd file setting up the environment and the command line option
/k (remain open) to
Assuming the file is called
qt5vars.cmd and the Qt folder is called
qt-5 and located under
REM Set up \Microsoft Visual Studio 2013, where <arch> is \c amd64, \c x86, etc. CALL "C:\Program Files (x86)\Microsoft Visual Studio 12.0\VC\vcvarsall.bat" <arch> SET _ROOT=C:\qt\qt-5 SET PATH=%_ROOT%\qtbase\bin;%_ROOT%\gnuwin32\bin;%PATH% REM Uncomment the below line when using a git checkout of the source repository REM SET PATH=%_ROOT%\qtrepotools\bin;%PATH% SET QMAKESPEC=win32-msvc2013 SET _ROOT=
A desktop link can then be created by specifying the command
%SystemRoot%\system32\cmd.exe /E:ON /V:ON /k c:\qt\qt5vars.cmd as application and
c:\qt\qt-5 as working directory.
Note: Setups for MinGW are similar; they differ only in that the
bin folder of the installation should be added to the path instead of calling the Windows SDK setup script. For MinGW, please make sure that no
sh.exe can be found in the path, as it affects
Settings required by the additional libraries (see Qt for Windows Requirements) should also go this file below the call to the Windows SDK setup script.
Step 4: Build the Qt Library
The default behavior of configure is to create an in-source build of Qt 5. If you want to install Qt 5 to a separate location, you need to specify the command line option
-prefix <location>. Alternatively, the command line option
-developer-build creates an in-source build for developer usage.
To configure the Qt library for a debug build for your machine, type the following command in the command prompt:
configure -debug -nomake examples -opensource
The Configure Options page contains more information about the configure options.
To build Qt using jom, type:
If you do not have jom installed, type:
For MinGW, type:
If an installation prefix was given, type
nmake install or
Note: If you later need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed by entering the build directory and typing
nmake distclean before running
jom is a replacement for
nmake which makes use of all CPU cores and thus speeds up building.
