HOW TO BUILD QT5

Synopsis ========

System requirements ------------------

- Perl 5.8 or later
- Python 2.7 or later
- C++ compiler supporting the C++11 standard

 For other platform specific requirements,
 please see section "Setting up your machine" on:
 http://wiki.qt.io/Get_The_Source

Licensing: ----------

Opensource users:

            = -opensource

Commercial users:

            = -commercial

Linux, Mac: -----------

 cd /
 ./configure -prefix $PWD/qtbase  -nomake tests
 make -j 4

Windows: --------

 Open a command prompt.
 Ensure that the following tools can be found in the path:
 * Supported compiler (Visual Studio 2012 or later,
    MinGW-builds gcc 4.9 or later)
 * Perl version 5.12 or later   [http://www.activestate.com/activeperl/]
 * Python version 2.7 or later  [http://www.activestate.com/activepython/]
 * Ruby version 1.9.3 or later  [http://rubyinstaller.org/]

 cd \
 configure -prefix %CD%\qtbase  -nomake tests
 nmake // jom // mingw32-make

 To accelerate the bootstrap of qmake with MSVC, it may be useful to pass
 "-make-tool jom" on the configure command line. If you do not use jom,
 adding "/MP" to the CL environment variable is a good idea.

More details follow.

Build! ======

A typical `configure; make’ build process is used.

Some relevant configure options (see configure -help):

-release Compile and link Qt with debugging turned off.
-debug Compile and link Qt with debugging turned on. -nomake tests Disable building of tests to speed up compilation -nomake examples Disable building of examples to
speed up compilation -confirm-license Automatically acknowledge
the LGPL 2.1 license.

Example for a release build: (adjust the `-jN’ parameter as
appropriate for your system)

./configure -prefix $PWD/qtbase make -j4

Example for a developer build: (enables more autotests, builds debug
version of libraries, …)

./configure -developer-build make -j4

See output of `./configure -help’ for documentation on various
options to configure.

The above examples will build whatever Qt5 modules have been enabled
by default in the build system.

It is possible to build selected modules with their dependencies by
doing a `make module-’. For example, to build only
qtdeclarative, and the modules it depends on:

./configure -prefix $PWD/qtbase make -j4
module-qtdeclarative

This can save a lot of time if you are only interested in a subset of
Qt5.

Hints =====

The submodule repository qtrepotools contains useful scripts for
developers and release engineers. Consider adding qtrepotools/bin to
your PATH environment variable to access them.

The qt5_tool in qtrepotools has some more features which may be of
interest. Try `qt5_tool --help’.

Building Qt5 from git ===================== See
http://wiki.qt.io/Building_Qt_5_from_Git and README.git for more
information. See http://wiki.qt.io/Qt_5 for the reference platforms.

Documentation =============

After configuring and compiling Qt, building the documentation is
possible by running “make docs”.

After having built the documentation, you need to install it with the
following command:

make install_docs

The documentation is installed in the path set to $QT_INSTALL_DOCS.
Running “qmake -query” will list the value of QT_INSTALL_DOCS.

Information about Qt 5’s documentation is located in
qtbase/doc/README or in the following page:
http://wiki.qt.io/Qt5DocumentationProject

Note: Building the documentation is only tested on desktop platforms.
