System requirements
------------------
- Perl 5.8 or later
- Python 2.7 or later
- C++ compiler supporting the C++98 standard
For other platform specific requirements,
please see section "Setting up your machine" on:
http://qt-project.org/wiki/Get_The_Source
Optional requirements
---------------------
- OpenSSL for SSL sockets or HTTPS
- Wayland
- See QtWebKit section.
New dependencies in Qt 5
------------------------
Linux: On systems running X11, the XCB libraries are required for
the platform plugin to build. qtbase/src/plugins/platforms/xcb/README
lists the required packages.
Qt 5 can make use of the ICU libraries providing Unicode and Globalization
support (see http://site.icu-project.org/). They are required for building
QtWebKit.
On Linux, they will be auto-detected.
On Windows, they need to be manually installed and the "include" and "lib"
folders of the ICU installation must be appended to the INCLUDE and LIB
environment variables after calling the Windows SDK setup script.
The "bin" folder of the ICU installation should be appended to the PATH
environment variable in order to for the DLLs to be found at run-time.
Linux, Mac:
-----------
cd <path>/qt-everywhere-opensource-src-<version>
export PATH=$PATH:$PWD/qtbase/bin
./configure -prefix $PWD/qtbase -opensource -nomake tests
Windows:
--------
Open a Windows SDK (7.0, 7.1 or later) command prompt. Ensure that Perl
version 5.12 or later and Python version 2.7 or later can be found in the
path.
cd <path>\qt-everywhere-opensource-src-<version>
set PATH=%PATH%;%CD%\qtbase\bin;
configure -prefix %CD%\qtbase -opensource -nomake tests
perl build
For MinGW (gcc version 4.6 or later), ensure that the compiler can
be found in the path.
The build script will use jom if it's found in the path, which means you can
use -j <n> options on Windows as well. If not, the /MP option is added to the
compile options of the Microsoft Visual Studio compiler, to use all available
cores for batch building.
Building QtWebKit
=================
Linux, Mac:
-----------
The tools bison, flex and gperf which are required for building.
cd qtwebkit
export WEBKITOUTPUTDIR=$$PWD/WebKitBuild
perl Tools/Scripts/build-webkit --qt --qmake=../qtbase/bin/qmake --install-libs=<install dir> --release --makeargs=$MAKEFLAGS
Windows:
--------
The tools bison, flex and gperf which are required for building are
provided for convenience in the folder gnuwin32\bin.
set PATH=%PATH%;%CD%\gnuwin32\bin
cd qtwebkit
set WEBKITOUTPUTDIR=%CD%/WebKitBuild
perl Tools\Scripts\build-webkit --qt --qmake=..\qtbase\bin\qmake.exe --install-libs=<install dir> --release --makeargs=%MAKEFLAGS%
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 -opensource
Example for a developer build:
(enables more autotests, builds debug version of libraries, ...)
./configure -developer-build -opensource
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-<foo>'. For example, to build only qtscript and qtwebkit,
and the modules they depend on:
./configure -prefix $PWD/qtbase -opensource
make -j4 module-qtscript module-qtwebkit
This can save a lot of time if you are only interested in a subset of Qt5.
Hints
=====
Shadow builds are possible, but not as well tested/supported as in-source
builds.
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
=====================
