HOW TO BUILD QT5 ================ Synopsis ======== 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 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 /qt-everywhere-opensource-src- ./configure -prefix $PWD/qtbase -opensource -nomake tests make -j 4 Windows: -------- Open a Windows SDK (7.0, 7.1 or later) command prompt. Ensure that the following tools can be found in the path: * 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 \qt-everywhere-opensource-src- configure -prefix %CD%\qtbase -opensource -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 -opensource make -j4 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-'. 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 ===== 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://qt-project.org/wiki/Building-Qt-5-from-Git and README.git for more information. See http://qt-project.org/wiki/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://qt-project.org/wiki/Qt5DocumentationProject Note: Building the documentation is only tested on desktop platforms.
