This version of PyQt is to be used with the non-commercial version of Qt based on Qt v2.3.0. Your application must be released under a license that is compatible with the Qt Non-commercial license. Educational License.
You can download the Qt 5 sources from the Downloads page. For more information, visit the Getting Started with Qt page.
Qt for X11 has some requirements that are given in more detail in the Qt for X11 Requirements document.
Step 1: Installing the License File (Commercially Licensed Qt Only)
If you use Qt with a commercial license, the Qt tools look for a local license file. If you are using a binary installer or the commercial Qt Creator, your licenses are automatically fetched and stored in your local user profile (
$XDG_DATA_HOME/Qt/qtlicenses.ini
file).If you do not use any binary installer or Qt Creator, you can download the respective license file from your Qt Account Web portal and save it to your user profile as
$HOME/.qt-license
. If you prefer a different location or file name, you need to set the QT_LICENSE_FILE
environment variable to the respective file path.Step 2: Unpacking the Archive
Unpack the archive if you have not done so already. For example, if you have the
qt-everywhere-opensource-src-%VERSION%.tar.gz
package, type the following commands at a command line prompt:This creates the directory
/tmp/qt-everywhere-opensource-src-%VERSION%
containing the files from the archive. We only support the GNU version of the tar archiving utility. Note that on some systems it is called gtar.Step 3: Building the Library
To configure the Qt library for your machine type, run the
./configure
script in the package directory.By default, Qt is configured for installation in the
/usr/local/Qt-%VERSION%
directory, but this can be changed by using the -prefix
option.The Configure Options page contains more information about the configure options.
To create the library and compile all the examples, tools, and tutorials, type:
If
-prefix
is outside the build directory, you need to install the library, examples, tools, and tutorials in the appropriate place. To do this (as root if necessary), type:Note that on some systems the make utility is named differently, like gmake. The configure script tells you which make utility to use.
Note: Later, if you need to reconfigure and rebuild Qt from the same location, ensure that all traces of the previous configuration are removed. To do so, from the build directory, type
make confclean
before running configure
again.Step 4: Set the Environment Variables
To use Qt, some environment variables need to be extended.
This is done as follows:
In
.profile
(if your shell is bash, ksh, zsh or sh), add the following lines:In
.login
(if your shell is csh or tcsh), add the following line:If you use a different shell, modify your environment variables accordingly.
For compilers that do not support rpath you must also extend the
LD_LIBRARY_PATH
environment variable to include /usr/local/Qt-%VERSION%/lib
. On Linux with GCC this step is not needed.Step 5: Build the Qt Documentation
For the Qt reference documentation to be available in Qt Assistant, you must build it separately:

This page describes the process of configuring and building Qt for Windows. Before building, there are some requirements that are given in more detail in the Qt for Windows - Requirements document.
You can download the Qt 5 sources from the Downloads page. For more information, visit the Getting Started with Qt page.
Step 1: Install the License File (Commercially Licensed Qt Only)
If you use Qt with a commercial license, the Qt tools look for a local license file. If you are using a binary installer or the commercial Qt Creator, your licenses are automatically fetched and stored in your local user profile (
%USERPROFILE%AppDataRoamingQtqtlicenses.ini
file).If you do not use any binary installer or Qt Creator, you can download the respective license file from your Qt Account Web portal and save it to your user profile as
%USERPROFILE%.qt-license
. If you prefer a different location or file name, you need to set the QT_LICENSE_FILE
environment variable to the respective file path.Step 2: Unpack the Archive
Uncompress the files into the directory you want Qt installed; e.g.
C:Qt%VERSION%
.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 Visual Studio. 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 cmd.exe
.Assuming the file is called
qt5vars.cmd
and the Qt folder is called Qt-5
and located under C:Qt
:A desktop link can then be created by specifying the command
%SystemRoot%system32cmd.exe /E:ON /V:ON /k C:Qtqt5vars.cmd
as application and C:QtQt-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 Visual Studio setup script. For MinGW, please make sure that no sh.exe
can be found in the path, as it affects mingw32-make
.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:
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
jom install
, nmake install
or mingw32-make install
.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 configure
again.Parallel Builds
jom is a replacement for
nmake
which makes use of all CPU cores and thus speeds up building.Step 5: Build the Qt Documentation
