Building
|
|
|
========
|
|
|
Please note that if you have already installed a previous version of
|
|
|
QtCommercial 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 install the libraries to your Qt library directory use:
|
|
|
make install
|
|
|
|
|
|
If you want to uninstall the libraries
