Building
|
|
|
========
|
|
|
|
|
|
Please note that if you have already installed a previous version of
|
|
|
Qt Charts, you should first uninstall it with
|
|
|
make uninstall
|
|
|
|
|
|
Configure project with qmake and build project with make:
|
|
|
(Linux) make
|
|
|
(Windows with MinGw) mingw32-make
|
|
|
(Visual Studio) nmake
|
|
|
(OSX) make
|
|
|
|
|
|
For debug builds:
|
|
|
qmake CONFIG+=debug; make
|
|
|
or
|
|
|
qmake CONFIG+=debug_and_release; make debug
|
|
|
|
|
|
For release builds:
|
|
|
qmake CONFIG+=release; make
|
|
|
or
|
|
|
qmake CONFIG+=debug_and_release; make release
|
|
|
|
|
|
For both builds:
|
|
|
qmake CONFIG+="debug_and_release build_all"; make
|
|
|
|
|
|
If you want to leave out demos and examples from the build you can use
|
|
|
the following config with qmake:
|
|
|
CONFIG+=nomake_demos_examples
|
|
|
For some embedded environments, such as VxWorks, all examples and demos
|
|
|
may not be applicable. There it's recommended to use the above mentioned
|
|
|
config option.
|
|
|
|
|
|
If you want to install the libraries to your Qt library directory use:
|
|
|
make install
|
|
|
|
|
|
If you want to uninstall the libraries:
|
|
|
make uninstall
|
|
|
|
|
|
Building as a statically linked library
|
|
|
=======================================
|
|
|
|
|
|
The same as above applies, you will just have to add staticlib to the CONFIG:
|
|
|
qmake CONFIG+=staticlib
|
|
|
|
|
|
Documentation
|
|
|
=============
|
|
|
|
|
|
Documentation can be found from doc/html and doc/qch directories. The documentation
|
|
|
can also be generated with:
|
|
|
make docs
|
|
|
|
|
|
The documentation provided with Charts is generated with qdoc and the creation of the
|
|
|
documentation is prioritized for Qt5. We recommend building the documentation using Qt5,
|
|
|
if you want to do it yourself. Creating the documentation using Qt4 also works, but some
|
|
|
pages are not generated correctly, such as the 'List of All Members' page for all C++ and
|
|
|
QML APIs in .qch documentation.
